How to manage wheat at filling stage to achieve high yield?

after heading and flowering, wheat is about to enter the filling stage. At this time, the number of ears per mu in the field has been fixed. In order to improve the yield, there are only two ways, one is to increase the number of grains per ear, that is, the number of grains per ear, and the other is to increase the weight of grains, that is, the weight of each grain. The above two kinds of things have a very important impact on the yield of wheat. Here's how to manage them:

1. Attention should be paid to lodging of wheat. Once lodging of wheat occurs, it will have a great impact on yield. There are many factors that can easily cause lodging, such as continuous heavy rain and strong wind, which can easily lead to lodging of wheat. Other diseases will also increase the probability of lodging of wheat, such as root rot.

2. Spraying foliar fertilizer

Spraying foliar fertilizer has many benefits. First, it can provide nutrients for wheat growth, especially some medium and trace elements, which is beneficial to the increase of grain weight; Secondly, the function of blades is increased, and the harm of dry hot wind is reduced; Third, improve the filling rate of wheat in the field, effectively increase the grain weight and promote the high yield of wheat.

3. Watering

There are different opinions about watering. Some people think that watering during grouting is easy to cause lodging, and this situation will exist. However, for relatively dry plots, watering is needed to promote the normal growth of wheat. During the whole growth period of wheat, from filling to maturity, the demand for water is relatively large, accounting for about 2%-25% of the whole growth period.

4. Weeding

I believe many friends will have different views on weeding during wheat filling period. At this time, if herbicides are applied again, the probability of phytotoxicity will be greatly increased. In addition, the growth of wheat is higher than that of many weeds, and it is not easy to spray on weeds. Therefore, the weeding mentioned here is carried out when there are too many weeds in the field. Some fields may not be weeded in the early stage, or the weeding effect is not good. It affects the normal growth of wheat. At this time, manual weeding is needed to ensure the normal growth of wheat and improve the final yield. This is not mandatory, and it depends on the specific situation. After all, under the condition of large-scale planting, manual weeding is not practical.

the above four points are the management measures that need to be taken during wheat filling, which have a good effect on increasing the number of grains per spike and improving the grain weight. Of course, in the actual planting process, everyone should also choose their own measures according to the specific situation, and it is not necessary to implement them all.

May is the key period for the formation of wheat yield, and the filling period is the key period for determining the 1-grain weight of wheat. Good management in this period directly affects the wheat yield, so it is necessary to strengthen the management of wheat filling period.

in order to ensure the high and stable yield of wheat, combined with the growth and development characteristics of wheat and the current wheat situation, I put forward the following management suggestions, hoping to be useful to everyone.

1. Supplementing nitrogen fertilizer and irrigating slurry water

At this time, the wheat is in the flowering period. After 1-15 days, about 5kg of urea should be topdressing per mu, combined with watering and flushing, so as to prolong the filling time. However, if you know that the wind and rain are coming, you can't water it to prevent lodging, and you can't topdressing too much nitrogen fertilizer to prevent greed and late maturity.

if the base fertilizer is sufficient and nitrogen fertilizer is topdressing in spring, urea can not be topdressing at this time, and 2g of potassium dihydrogen phosphate and 5g of urea can be sprayed on the leaves and mixed with water for 3--4kg, and then sprayed again after 7-1 days.

2, pest control

With the increase of temperature and humidity, wheat powdery mildew, rust, aphids, red spiders, wheat sawflies and other pests and diseases will occur. At this time, we must do a good job of spraying three or four defenses to prevent diseases, insects, dry heat and wind and lodging.

Wheat powdery mildew will harm wheat leaves, which will lead to the failure of photosynthesis and reduce the yield. The flag leaf and the inverted second leaf of wheat are seriously damaged, and the yield will be greatly reduced, and it is easy to lodging and increase the number of grains.

Wheat rust also harms leaves, stems and ears, which directly affects the yield.

triadimefon, also called triadimefon, can be applied to diseases, and it has special effects on powdery mildew and rust of wheat. There are carbendazim, tebuconazole, propiconazole and so on.

Aphids can suck leaf juice and grain slurry, resulting in a 2-3% decrease in yield, and in severe cases, it can reach more than 5%.

The available pesticides are imidacloprid, acetamiprid, abamectin, pyridaben and beta-cypermethrin.

The above chemicals for preventing and controlling wheat diseases and insect pests can be used alternately, and brassinolide can be added at the same time, which can improve the strength of wheat stalks, reduce the harm of dry-hot wind, and speed up grain filling, and play an important role in improving the 1-grain weight and grain quality of wheat.

how to manage wheat at grain filling stage to achieve high yield?

two things should be done well during wheat filling period, namely, water management and disease prevention, in order to achieve high yield. During wheat filling period, it is rainy or spring drought, and water management is particularly important. There are many spring rains, high temperature in late spring and early summer, and serious water accumulation in wheat fields, which is not conducive to wheat irrigation. It will induce premature aging of wheat roots, affect filling, and also cause diseases such as wheat scab and stem rust. If there is a spring drought, it will affect the water demand for wheat filling, make the grain filling insufficient, and have more grains, which will affect the quality and yield of wheat.

first, the management of water in wheat filling stage. During the wheat filling period, we are not only afraid of more rain, waterlogging and diseases, but also afraid of the coming of spring drought, which will affect grain filling. During the wheat filling period, if there is too much spring rain, remember to manage the wheat field well, ditch and clear the ditch, repair the drainage channel from the wheat field to the outside, dredge and remove impurities to prevent blockage; Repair every drainage ditch in the wheat field to improve the drainage effect and enhance the ability of filtering water and stains. Do it rain, there is no water in the wheat field, reduce the soil water content in the wheat field, and avoid causing wheat root rot and inducing scab and rust. If the spring drought comes, the soil moisture content of wheat field will decrease, so as to avoid affecting wheat filling, irrigation should be done immediately, and irrigation should be done quickly, so as not to cause diseases by flooding slowly.

second, the prevention and control of wheat diseases during grain filling. At the wheat filling stage, it is the high temperature and high humidity season, which is the high incidence period of wheat scab and stem rust. The period from flowering to filling stage of wheat is the key period for chemical control of scab and stem rust. Wheat scab is sprayed for the first time at the flowering stage of wheat, and it should be sprayed before flowering at the latest, usually for the second time every 7 days. At present, the effective agents for preventing and controlling scab are 5% thiophanate methyl wettable powder 1-15 times solution, 5% carbendazim 1-15 times solution, 4% mirex gel suspension 1-15 times solution, and .5 .8 Baume sulfur mixture spray. The best chemical control period of stem rust is generally spraying at the flowering and filling stage of wheat. Effective agents for preventing and controlling wheat straw rust are sodium antirust, Weixiu powder and triadimefon.

In short, wheat must grasp two points during grain filling, manage water well and prevent diseases. If these two points are done well, it is inevitable to have a bumper harvest and high yield.

Today is May 3rd in the solar calendar, and wheat is at the end of flowering! How can we make wheat stable and high yield during the upcoming wheat filling period?

In mid-May, wheat was sprayed with "one spray and three defenses". Because it rained several times in eastern Henan during this period, the drought here has been greatly alleviated! For the current situation, I think our farmers here should spray the pesticide of "one spray and three defenses" in time!

Yesterday, my daughter-in-law just sprayed the wheat on our five acres of land, with high-fluorine cypermethrin+brassinolide+potassium dihydrogen phosphate+medium and trace element fertilizer+tebuconazole prochloraz! A * * * spent nearly 5 yuan money! Because I contracted land for planting in previous years, I am familiar with the owner of agricultural stores, and the price is more favorable! 5 mu of land was sprayed with 6.5 barrels of water! The rest was sprayed into the garlic field! If conditions permit, you can also use polonium to apply urea to wheat again, with an area of about 2-25kg per mu! Wheat during grouting really needs fertilizer, and the soil moisture here is better this year.

You can also spray bactericide+potassium dihydrogen phosphate+urea once every other week! At this time, spraying fertilizer on leaves can also increase wheat production!

The warm spring is coming, and the hot summer is coming. With the increase of temperature, wheat basically entered the filling stage. The management of wheat filling period plays an important role in improving the quality and yield of wheat.

So how to manage during the wheat filling period to achieve the goal of high yield?

when wheat enters the grain filling stage, the growth of wheat needs to absorb a lot of nutrients and water. Therefore, the management of water and fertilizer in this period is particularly important. If nutrition and water are not available during this period, it will seriously affect the yield of wheat.

The soil in wheat field is too dry or the humidity in the field is too high, and even water accumulation is not conducive to the growth of wheat. A few days ago, there was continuous rain, wind and even hail in some places in the young man's hometown. Such weather has a great influence on the growth of wheat. Continuous rainfall makes the soil moisture in the field too high, which is very unfavorable to the respiration of wheat roots. Coupled with the wind, there are several wheat lodging in the village. If there is water in the field, drainage work should be carried out in time.

During the wheat filling stage, it is necessary to avoid the fertilizer removal and premature aging of wheat. In this period, due to the need for a lot of nutrition, the absorption of roots can not fully meet the growth needs of wheat, coupled with excessive soil moisture or diseases and insect pests and other factors, it is easy to cause premature aging of wheat. Under the condition of ensuring soil fertility, it is necessary to spray potassium dihydrogen phosphate on wheat in time, and the premature aging of wheat can be well prevented by supplementing phosphorus and potassium elements on the leaves.

do a good job of "one spraying and three prevention" to protect the high yield of wheat. During the wheat filling period, spraying potassium dihydrogen phosphate and brassinolide can make the roots and stalks of wheat stronger, prevent premature aging of wheat, increase the ability to resist dry and hot wind, and play a very important role in improving the quality and yield of wheat. Adding thiophanate methyl wettable powder or carbendazim can control wheat scab and stem rust; Adding chlorpyrifos or imidacloprid can control aphids, red spiders and other pests.

to sum up, the management of wheat filling period has an important influence on the quality and yield of wheat. Only by doing every job carefully can the high quality and high yield of wheat be guaranteed.

The wheat filling period is the last important growth link that affects the final yield of wheat, so it is very important to manage it reasonably and scientifically during the wheat filling period. Then Lao Zhang told fellow villagers what to do during the wheat filling period to improve the yield of wheat.

1. Rational fertilization.

at this time, it is necessary to apply foliar fertilizer (.5% potassium dihydrogen phosphate +1% urea+brassin mixture) to wheat. At this time, spraying foliar fertilizer in time is conducive to prolonging the senescence of wheat leaves, maintaining plant vitality and continuously maintaining high disease resistance. More importantly, it can improve the plumpness and dry weight of wheat particles.

2. Take timely measures to prevent pests and diseases.

third, reasonable irrigation.

In general, it is beneficial to increase the yield of wheat if it is irrigated during the wheat filling period. However, in actual production, we should pay attention to whether the growth of wheat is too strong. If it is too strong, it will easily lead to wheat lodging and affect the yield. Therefore, it is necessary to judge whether to irrigate wheat according to the soil moisture and the growth of wheat. If it is half irrigated, just soak it in the field for a long time.

The above is the method given by Lao Zhang on how to scientifically manage wheat during grain filling to increase production. Forgetting can help everyone.

With the change of seasons, it has entered the poplar flowering period of wheat, followed by the critical period of wheat management, which affects wheat yield. During this period, due to the changeable weather, especially rainy weather and some irresistible bad weather, wheat diseases and insect pests will occur, which will affect wheat yield, so the management of wheat in this period is particularly critical.

first of all, talk about which diseases and insect pests occur in grain filling stage, mainly wheat rust, powdery mildew, scab and sheath blight. Once these diseases occur, they will have a serious impact on wheat, especially after rainy weather every time. If they are not controlled, they will spread quickly. Because we all know that there are a lot of wheat rust when harvesting wheat every year, and the reasons are all these diseases.

The main pests are ear aphid, wheat midge and wheat red spider. Especially in continuous rainy weather, ear aphid will occur seriously. The most important thing is to prevent and control wheat midge in time, and suck the grain slurry during wheat filling, resulting in shriveled grains, empty shells and reduced production. When it happens, there will be no grain harvest in the whole field.

Based on the above analysis, the most important thing for wheat at present is one spray and three defenses. Now, one spray and three defenses can not only prevent and control the occurrence of wheat diseases, but also resist lodging and cope with bad weather at any time. As for the drugs for spraying foliar fertilizer at present, there is no unified regulation, mainly fungicides and foliar fertilizers for growing wheat with lodging resistance and disease resistance, and mainly triadimefon and diniconazole can prevent powdery mildew and rust by spraying. Wheat root rot can be controlled by triadimefon, thiram and chlorphenamine. If there are pests, pirimicarb or 4% omethoate and cypermethrin can be used to control wheat midge. Every time, foliar fertilizer with potassium dihydrogen phosphate, brassinolide and amino acid as the main ingredients should be used to resist diseases and increase production.

At present, there are many wheat-specific one-spray three-proofing agents with good effects on the market. It is recommended to buy them from agricultural stores with good credit. When spraying, it is best to use sunny weather before 1 am and after 4 pm, with the best effect.

First of all, thank you very much for your invitation. The filling stage of wheat is the key stage of grain formation, which determines the 1-grain weight of wheat. However, under the premise of a certain number of ears per mu and grains per ear, the growth of wheat in the key stage will determine the final yield. Therefore, the management of grouting period is particularly important.

generally speaking, the following two points should be done well during grain filling period to lay a solid foundation for high yield of wheat. First, we should do a good job in the regulation of water and fertilizer. The increase of 1-grain weight of wheat is actually the transfer of photosynthetic products, so it is essential to find ways to prolong the photosynthetic performance of leaves. Generally speaking, the grouting water should be poured once according to the soil moisture during the grouting period, and the amount of water should not be too large for about 2 cubic meters, so as to provide suitable water for grain grouting. It is best to irrigate grouting water in the middle of grouting, and irrigation must be stopped 1 days before harvest. If the leaves are aging, a small amount of foliar fertilizer such as potassium dihydrogen phosphate should be added at the same time to prolong the green retention of the leaves and escort the photosynthesis.

if you are planting fields, you should do the last purification and rejuvenation before harvesting.

The above are only personal opinions, and you are welcome to make more valuable suggestions.

wheat enters the filling stage, which is also formed by wheat grains.
