Soybean fertilization technology, topdressing method, fertilization time

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, and 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 will take you to know more! 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 20kg ternary compound fertilizer is applied per mu, or 1500-2000kg decomposed organic fertilizer is applied as base fertilizer.

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 kilograms of urea nitrogen is used in rainy acres, and urea can be reduced or not applied as appropriate if the plants grow too vigorously.

The dilute solution of ammonium molybdate or calcium superphosphate can also be sprayed on the leaves of soybean at seedling stage and early flowering stage respectively to improve fertilizer efficiency and increase yield.

During the period from early flowering to pod filling, if the weather is dry, water it in time to prevent the yield from being affected by drought.

Soybean topdressing method After soybean emergence, 3-5 kilograms of urea can be topdressed per mu when the compound leaves of soybean sprouts are unfolded. Green food soybean, using organic fertilizer instead of chemical fertilizer, using 500 kilograms of high-quality agricultural fertilizer per mu.

If the seedlings are strong and there is 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 of fertilizer demand, and it is also the vigorous period of soybean growth and development. Applying proper amount of nitrogen fertilizer 5-7 days before flowering or at the early 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.

Generally, topdressing ammonium nitrate is about 200-250 kg or urea is about 130- 160 kg 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 of absorbing fertilizer weakened. Topdressing outside the root, that is, foliar spraying, is very important for improving soybean maturity, increasing 100-grain weight and improving soybean quality.

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

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

The dilute solution of ammonium molybdate or calcium superphosphate can also be sprayed on the leaves of soybean at seedling stage and early flowering stage respectively to improve fertilizer efficiency and increase yield.

During the period from early flowering to pod filling, if the weather is dry, water it in time to prevent the yield from being affected by drought.

Soybean fertilization, focusing on phosphorus, nitrogen and potassium as appropriate.

Generally, high phosphate fertilizer 10-20k g, urea 58kg, or diammonium 15-20k g are applied at the bottom of one acre.

Applying ammonium molybdate to soybean seed dressing, spraying Woye boron fertilizer and foliar fertilizer at full flowering stage, the yield increase effect is remarkable.
