Ordering beans and fertilizing slogans

We are all familiar with soybean, which is one of the important food crops in China, also known as soybean. It is often used to make all kinds of bean products, soy sauce or extract soybean oil, which has a wide range of utilization value in our lives.

So, do you know how to fertilize soybeans? When to fertilize? The following small series takes you to learn more about it! Soybean fertilization technology 1, applying sufficient base fertilizer to cultivate strong seedlings.

The growth of soybean seedlings needs certain nutrients. Before sowing, nitrogen, phosphorus and potassium should be added as base fertilizer to help strong seedlings resist diseases.

Generally, about 20 kilograms of ternary compound fertilizer is applied per mu, or basal fertilizer 1500-2000 kilograms of decomposed organic fertilizer is applied.

2. Generally, calcium superphosphate 18 ~ 15 kg or diammonium phosphate 5 kg is used as seed fertilizer per mu, and borax 0.4 ~ 0.6 kg is added to boron-deficient soil.

3. timely topdressing.

Topdressing nitrogen fertilizer at the initial flowering stage can promote the development of flowers and the growth of young pods.

Generally, 4-5 kg urea nitrogen is used in rainy acres, and urea can be reduced or not applied as appropriate if the plants grow too vigorously.

You can also spray dilute solution of ammonium molybdate or calcium superphosphate at seedling stage and early flowering stage of soybean, so as to improve fertilizer efficiency and increase yield.

During the period from the first flowering to pod setting and filling, if the weather is dry, it is necessary to water at an appropriate time to prevent the yield from being affected by drought.

Top dressing method of soybean After soybean emergence, 3-5 kilograms of urea can be topdressing per mu when soybean sprouts are unfolded and compound leaves are applied. For green food soybeans, organic fertilizer is applied instead of chemical fertilizer, and 500 kilograms of high-quality agricultural fertilizer is applied per mu.

If the seedlings are healthy and have no fertilizer, no or less nitrogen fertilizer can be applied at the seedling stage to avoid the plants growing in vain.

The flowering and pod setting period is the key period for soybean to need fertilizer, and it is also the vigorous period for soybean growth and development. Applying an appropriate amount of nitrogen fertilizer 5-7 days before or at the initial flowering stage of soybean can promote the formation of carbohydrates and protein, reduce the abscission of flowers and pods, promote early maturity and increase yield, with obvious effect.

The results showed that topdressing nitrogen fertilizer in this period increased the yield by more than 10% compared with ordinary mu without topdressing nitrogen fertilizer.

Usually, about 200-250kg of ammonium nitrate or about130-160kg of urea are topdressing per hectare, combined with intertillage and soil cultivation.

In addition, soybean should be supplemented with topdressing. When soybean entered the stage of pod setting and grain filling, the root activity decreased and the ability to absorb fertilizer weakened. Topdressing outside the root, that is, foliar spraying, is very important to improve soybean maturity, increase 100-grain weight and improve soybean quality.

Topdressing nitrogen fertilizer at the early flowering stage of soybean can promote the development of flowers and the growth of young pods.

Generally, 4-5 kg urea nitrogen is used in rainy acres, and urea can be reduced or not applied as appropriate if the plants grow too vigorously.

You can also spray dilute solution of ammonium molybdate or calcium superphosphate at seedling stage and early flowering stage of soybean, so as to improve fertilizer efficiency and increase yield.

During the period from the first flowering to pod setting and filling, if the weather is dry, it is necessary to water at an appropriate time to prevent the yield from being affected by drought.

Soybean fertilization focuses on phosphorus, nitrogen and potassium.

Generally speaking, 65,438+00-20kg of high phosphate fertilizer, 58kg of urea or 65,438+05-20kg of diammonium are applied to the bottom of an acre of land.

Applying ammonium molybdate to soybean seed dressing and spraying Woye boron fertilizer and foliar fertilizer at full flowering stage have obvious effects on increasing yield.

The above is the soybean fertilization technology, topdressing method and fertilization time introduced by Bian Xiao.
