Appropriately, the application of flower pod fertilizer from flowering to bulging period is the peak period of fertilizer demand. The fertilization plot with insufficient fertility should be followed by topdressing, and the application of diammonium 15~20 kg per mu can achieve obvious yield increase effect.
If there is a prosperous trend in the rationalization control, the initial flowering period should be sprayed with 15% paclobutrazol 40~50g plus 50kg per acre or 15ml with 25mg of water. If the flowering period is still prosperous, it can be controlled for the second time.
Drought-proof and anti-mite soybeans should be planted in the early stage of the pod to the pod-forming period. In case of drought, water should be watered in time, and attention should be paid to drainage to avoid aggravating the disease.
Spraying foliar fertilizer In addition to the three major elements of NPK, boron, zinc and molybdenum are indispensable trace elements of soybean. Therefore, spraying multi-element complex nutrient solution during the flowering to the blast stage of soybean has the effect of increasing pod growth and increasing yield. The method is: 100 g of potassium dihydrogen phosphate per acre, 50 g of zinc phosphate, 50 g of borax (dissolved with hot water first) 25 g of ammonium molybdate, fully stirred with liquid, 50 kg of water, evenly sprayed on soybean The front and back sides of the blade are sprayed 2 to 3 times.
Prevention and control of pests and diseases The main control of soybean pests: 1. Soybean larvae are sprayed with 2.5% deltamethrin EC 1500~2000 times; 2. Bean hawk moth is sprayed with 20% fenvalerate EC 2500~3000 times; 3. Bean pods Spray with 50% thiophene emulsifiable concentrate 1000~1500 times. The main control of soybean diseases: gray spot disease, sprayed with 70% thiophanate-methyl WP 500-600 times or 50% thiram double-wet powder 500 times.
