Last Updated: 2024/11/06, First, the selection of improved varieties is the core to achieve high quality and high yield. Qindou 8 is the main variety, demonstrating and popularizing Zhonghuang 13, Jindou 23 and mutagenesis 30. Second, rational rotation and formula fertilization of soybean should avoid continuous cropping and welcome stubble. For the seriously affected fields, we should change to other crops, actively promote a reasonable system of crop rotation and reduce the number of years of continuous cropping and continuous cropping. According to the soil survey last year, the N:P:K of the soybean field in our town was 12:1:5, while the N:P:K required for soybean was 14:3.

I. selection of improved varieties

The selection of excellent varieties is the core to achieve high quality and high yield. Qindou 8 is the main variety, and Zhonghuang 13, Jindou 23 and Mutant 30 are demonstrated and popularized.

II. Rational crop rotation and formula fertilization

Soybean is the most avoid continuous cropping and welcome stubble. For the seriously affected fields, we should change to other crops, actively promote a reasonable system of crop rotation and reduce the number of years of continuous cropping and continuous cropping. According to the soil survey last year, the N:P:K of soybean fields in our town was 12:1:5, while the N:P:K needed for soybean was 14:3:5, indicating a serious lack of P element. According to 150kg soybean yield per mu, soybean fertilization should be based on base fertilizer. Generally, 2000 kg of farm manure should be applied before sowing, 17 kg of diammonium phosphate and 10 kg of urea before sowing. The foliar fertilizer can be sprayed with 15 grams of ammonium molybdate + 30 grams of Suele boron and 15-25 liters of water at flowering stage.

(3) sowing at the right time and reasonable close planting

The sowing date has a great influence on the yield and quality. Sowing at the right time has high seedling preservation rate, neat emergence, strong growth, strong stem and strong stem. The suitable sowing date of our town is mid-June or before, sowing about 7.5 kg per mu and keeping 1.5-20,000 seedlings per mu of medium fertility. The sowing depth should be 3 Mel. 5 cm to ensure that the seedlings are strong and uniform.

IV. Field management

1. Ploughing and weeding and fixing seedlings in time. Weeding in the 3-4 leaf stage can also be done with herbicides such as 5% fine grass 60 ml and spray with 30 kg water. Combine with ploughing to fix seedlings at one time.

2. prevention and control of diseases and insect pests. The focus of control is aphids, bean stem black miner and virus diseases. 15 days before flowering (about early July), 30 milliliters of 50% phoxim EC per mu, or 2.5% green time EC 15ml + 20% virus A wettable powder 60 grams, or 3.95% virus 45 grams, mixed with 30 kilograms of water, once every 10 days. Prevention and treatment for 3 times in a row.

Fifth, timely harvest

There is more overcast and rain in soybean harvest season, so we should pay close attention to harvest, threshing, prevent mildew and ensure high yield and harvest in the yellow ripening period.
