The continuous cloudy and rainy weather caused spring soybean seedlings to be thin, weak, and weedy, which may affect yield. To this end, special countermeasures are proposed to ensure stable production and high yield of soybeans.
Ditch drainage and dredge Sangou: Since the spring soybean planting, persistent rain has caused the soybean roots to be stunted and the distribution is shallow and less, once the water in the fields will rot. To this end, it requires the majority of farmers to do a good job of dredging the Sangou to prevent the ditch from collapsing and the ditching, so that no rain will accumulate in the rain and the rain will stop.
Do a good job of fertilizing: In view of the soil water, root damage, and impaired absorption function, it should be performed with 0.5% urea plus 0.2% potassium dihydrogen phosphate for extra-root dressing in general, usually twice in a row, separated by 7 days. Promote the early growth of seedlings, early leaves. For lack of fertilizer, defertilization field blocks, should be used with 5 kg of compound fertilizer or urea plus defecation water supplement once, in order to promote the recovery of spring soybean.
The cultivating loose soil: cultivating tillage on cloudy or sunny days to increase soil permeability to promote root growth and spring soybean growth.
Manual weeding and pest control: continuous rain will impede the growth of spring soybeans, which is beneficial to the breeding of weeds in the field. All localities must manually remove weeds after rainy days and promote the late growth of spring soybeans. Focus on the prevention and control of fungal diseases. Bean pods, bean hopper fly and other pests ensure that the spring soybeans grow robustly and improve their quality at a later stage.
