Pepper greenhouse slogan

What aspects should be taken to achieve high yield of pepper in greenhouse after autumn? With the continuous progress of science and technology, soilless cultivation and out-of-season growth of crops have become a reality, which greatly improves the yield of crops and meets the needs of the broad masses of the people. However, China is a country with vast territory and abundant resources, and the poverty level varies from place to place. In order to solve the poverty problem of the whole country, realize the simultaneous well-off of the whole country, encourage and support poverty-stricken areas to get rid of poverty, and encourage and support poverty-stricken areas to adjust their industrial structure in light of natural conditions.

Pepper is an indispensable and important food for every family, so it has also entered the line of sight of industrial restructuring, and many greenhouse peppers have appeared, most of which are delayed autumn peppers in greenhouses. In this paper, the efficient cultivation techniques of pepper in greenhouse after autumn were discussed.

Because pepper in autumn greenhouse is usually sown in summer and autumn and picked in winter and cold season, the climate problem is big and lasts for a long time. If you don't take care of it carefully, it will lead to the disaster in the early stage of pepper, and the yield of pepper will be reduced or even lost in the middle and late stage.

Therefore, it is necessary to take care of the peppers in the greenhouse in autumn and take various measures to ensure the yield of peppers. However, because it was planted in autumn, its climatic conditions were not suitable, so its output was affected. How to improve the yield of pepper in greenhouse after autumn is the primary difficulty at this stage. To delay the increase of pepper production in greenhouse in autumn, we should start from the following aspects.

1 According to the local climatic conditions, reasonably select the sowing seed yield which is harmful to pepper varieties, and select suitable pepper varieties to lay the foundation for increasing pepper production. Therefore, we must attach great importance to the selection of pepper varieties in late autumn. However, as industrial restructuring is a new project in China, the climatic conditions in different places are different, so we still need to consider the climatic factors when choosing.

1. 1 Selecting varieties Usually, because peppers that are delayed in autumn should be sown in summer and autumn and picked in winter, it is necessary to choose varieties that are heat-resistant in sowing season and low-temperature resistant in picking season to meet the requirements of climatic conditions. At the same time, in order to increase the mature season of pepper, mature varieties cannot be selected.

In order to prevent pepper diseases reasonably, it is necessary to choose varieties with good upward trend and strong antiviral ability to resist the harm of climate and epidemic situation and achieve the purpose of increasing production. As far as finished peppers are concerned, it is generally necessary to choose pepper seedlings with concentrated fruits, large fruits and thick flesh, and bright colors of mature peppers.

For example, in autumn, if you choose seeds that do not meet the above standards, the yield will generally be affected or even limited. If you choose seeds with early heat resistance, they will be harmed by high temperature and strong light in summer and autumn when sowing in spring and summer, which will lead to the death of pepper seedlings, which is very unfavorable for pepper production. Everything else is the same. If we don't follow certain natural laws when making choices, the growth of pepper seedlings will be affected, which will lay a curse for the limited production of pepper in the future.

1.2 After selecting good varieties for seed treatment, attention should also be paid to the seed solution. Generally speaking, in order to grow peppers scientifically and reasonably, peppers must be dried, soaked in warm water, cleaned and removed from impurities, disinfected with potassium permanganate, moisturized and replenished with water, and sown with teeth. For the actual safety operation procedures, you can check the relevant books, so I won't repeat them here.

2. Reasonable seedling cultivation and colonization 2. 1 Reasonable seedling cultivation After selecting suitable seeds, it is also necessary to carry out reasonable seedling cultivation and colonization of pepper seeds, which is also an essential process for increasing pepper production. Unlike crops such as corn and wheat that are planted immediately, pepper seedlings must be cultivated first and then planted.

Seedling raising of autumn pepper in greenhouse is generally carried out in the middle and late July, and the seedling raising address is selected in windproof, rainproof and shading areas, generally in the greenhouse with sunshade net and agricultural plastic film to prevent the skin of pepper seedlings from being sunburned by direct sunlight. In addition, it is necessary to pay attention to the natural ventilation of the nursery address, and pay attention to the setting of drainage ditch during centralized seedling raising to meet the water demand for early growth of pepper seedlings.

For example, in the process of planting pepper seedlings, because the variety of pepper is generally small, it is usually difficult to control the total number of plants without selecting seedlings. If it is too much, it will lead to competition among pepper seedlings for sunlight, water and its nutrient elements. Generally, seedling trays with different holes are selected according to different seedling ages, which will not easily lead to the decline of pepper yield. In the process of pepper seedling, if shading and natural ventilation are not in place, it will also lead to abnormal growth and development of pepper seedlings, because the vitality of pepper seedlings is sensitive in the early stage.

In autumn, the seedling raising period of pepper in greenhouse is relatively late, and it is in the season of high environmental temperature. Direct sunlight is very serious, and the lack of effective shading will lead to sunburn or death of pepper seedlings. In addition, excellent natural ventilation standards can promote the growth and growth of pepper seedlings, so we must attach great importance to natural ventilation in seedling stage, so as to create a good growth environment for pepper seedlings and ensure the quality of pepper seedlings.

2.2 When the pepper seedlings are reasonably planted for about 30 days, the duration is generally selected in the middle and late August, so it is necessary to plant the pepper seedlings and select the seedlings with good growth and strong plants. In order to prevent the root system of pepper seedlings from being damaged and improve the survival rate of seedlings, it is generally necessary to choose seedling tray medium for seedling raising.

After transplanting and planting, it is necessary to pay attention to the row spacing and spacing of pepper seedlings to ensure that they are scientific and not endanger the light between peppers, but they should not be too rare, which will lead to the consumption of land resources and the increase of planting costs. In the process of constant time, we must attach great importance to the selection of pepper seedlings. If we choose plants with poor growth and disease resistance, it will affect their future growth and development and directly affect the yield of delayed autumn pepper in greenhouse.

Therefore, when choosing to plant seedlings, we must make a scientific and reasonable choice, check the weather forecast in advance, choose the appropriate temperature for planting, and ensure the power supply after planting. The water flow for planting must be large and rapid, so that the soil can be fully wetted, and irrigation immediately after planting, so as to ensure the normal development of pepper seedlings, reasonably control the interval of pepper seedlings, ensure the intake of nutrients and ensure the supply of water, so as to achieve the normal growth of pepper seedlings.

In the process of planting, it is necessary to select the appropriate soil layer, carry out corresponding treatment, and choose organic fertilizer to solve the corresponding soil layer. In order to prevent pepper seedlings from being submerged in water during planting, the roots will be out of breath and rot, so the soil should be ridged to ensure its future yield will not be affected.

3. Strengthen plant management, apply fertilizer rationally and prevent diseases. 3. 1 Plant management After pepper seedlings are planted, in order to increase the yield of pepper, it is necessary to strengthen plant management. Under the premise of fully understanding the nutrient demand of plants, rational fertilization and strengthening management should be carried out to prevent and control plant diseases in time to ensure the normal development of plants.

3.2 Rational fertilization is a necessary condition to ensure the yield increase in the middle and late period. However, the abuse of organic fertilizer will not be worth the loss, which will lead to the death or disease of pepper seedlings, and will continue to lead to soil salinization and air pollution. Therefore, in the process of fertilization, it is necessary to fully investigate and master the situation of pepper seedlings, carry out soil testing and formula fertilization according to the actual situation, and apply fertilizer reasonably and moderately on the principle of making up the deficiency.

Usually, a combination of organic fertilizer and inorganic fertilizer is used to fertilize plants. For example, in the process of plant growth and development, if reasonable fertilization is not carried out, its plants are generally short, with low yield and weak disease resistance.

However, if too much fertilizer is applied or there is no symptomatic treatment, it will also cause adverse harm to plants. On the one hand, if fertilization is not symptomatic, there will be no actual effect, and the symptoms of plants will not be alleviated, which will endanger their healthy and happy growth and fruit yield. Even because plants can't absorb it, organic fertilizer will remain in the soil layer, polluting the natural environment of the soil, leading to the inability of land resources to continue planting crops.

On the other hand, excessive fertilization will not only make plants sick and endanger their physical and mental health, but also continue to cause soil salinization, pollute water sources and soil layers and destroy the ecological environment. Therefore, fertilization should be symptomatic and appropriate, so as to ensure the healthy growth of plants and protect the environment.

3.3 Disease Prevention In the process of plant growth and development, it is necessary to strengthen disease prevention, immediately care about the growth of plants, and treat them in time when there are signs of malignant transformation, so as to maintain the physical and mental health of plants. Because the pepper planted in greenhouse in autumn belongs to anti-season planting, the temperature in the early stage of planting is high, the sunshine time is long, and the environmental temperature and humidity in greenhouse are high, which is very easy to breed bacteria and endanger the growth and development of plants.

Therefore, it is necessary to strengthen disease prevention and control, and spray pesticides reasonably and properly, which can eliminate pathogenic bacteria and pests, but it does not damage the development of plants and the efficacy of fruits in the middle and late stages, so that customers can use them with peace of mind.

3.4 Prevention and control of pests and diseases In the plant development stage, it is necessary to strengthen the prevention of diseases, do a good job of disease prevention and control in advance, remove diseases on time, create a good growth environment for plant growth, and promote the healthy and happy growth of pepper plants. Like the use of fertilizer, the disease prevention of pepper plants also needs to ensure symptomatic treatment and appropriateness, otherwise it will also affect the physical and mental health of plants or pollute the natural environment of soil. If too much fertilizer is used, it will continue to promote the excessive amount of fertilizer carried on fruits, thus endangering the physical and mental health of consumers.

Therefore, in the process of pest control, we must strengthen observation and supervision, ensure the correct use of drugs for symptomatic treatment, protect the physical and mental health of plants, and eliminate pests and diseases. In the middle and late stage of plant development, it is necessary to prune and bifurcate, and immediately harvest mature fruits, so as to promote the rapid conclusion of plants and realize the plan of increasing pepper production.

Conclusion In recent years, with China's poverty alleviation work entering the decisive battle stage, industrial restructuring has been widely carried out nationwide. As an essential food for thousands of families, pepper has also entered the line of sight of industrial restructuring.

Out-of-season peppers have large sales and high prices, which can quickly increase people's income. Therefore, pepper planting in greenhouse rises rapidly in autumn. However, there are many factors that affect the yield when pepper is planted out of season. To achieve high yield of pepper, it is necessary to strengthen all aspects of regulation and control, and do a good job in seed selection, seedling raising, planting, fertilization and pest control, so as to achieve the goal of high yield of pepper.
