Soybeans: sowing time to ensure a seedling preservation seedlings

It is now the best sowing time for soybeans. However, the rainy days have affected the planting schedule of soybeans. How should farmers respond to such weather? Wang Zhixin, director of the Soybean Breeding Institute of the Jiamusi Branch of the Academy of Agricultural Sciences, proposed that crops should be planted in time when the crop was harvested to ensure that the seedlings were planted once.

Wang Zhixin said that recently there are more rainy weather, less sunshine, and lower temperatures, resulting in excessive soil moisture, and water accumulation on individual plots, affecting the planting schedule of soybeans. Farmers should give full play to the soil with moderate soil conditions. Large- and medium-sized planting machines have the advantages of fast operation speed and high seeding quality, and do not delay or accelerate the progress of planting; for large-scale soils and undulating terrain, it is possible to adopt sub-segmentation to sow higher topography of the soil. The section with relatively low water content shall be sown after the lower part of the terrain is fully dispersed; the land with clear water shall be timely excavated and drained; at the same time, the depth of sowing shall be determined according to the actual conditions, and the soil moisture shall be too large. The plots should be appropriately broadcasted and repressive measures should be taken the next day; for the plots where the fertilisers are applied at the same time, it is necessary to pay attention to stratified application to avoid the phenomenon of “burning seedlings”; The actual situation of replacement of early-maturing soybean seeds, to avoid the phenomenon of late maturity and green beans after autumn, affecting soybean yield and quality.

Sowing early-maturing soybeans can appropriately increase the sowing density, so that it can be safely matured and yield can be guaranteed. In terms of soybean seeds, it is necessary to select the original species or field crops produced by the regular seed industry, and the farmers should also maintain the seeds for their own retention. Selective treatment can ensure higher seed vigor and germination rate, improve resistance to low-temperature and high-humidity soil conditions, and at the same time, coat seeds to prevent white seeds from falling to the ground to facilitate the prevention and control of early diseases and insect pests; In the case of rainfall, low temperature, and excessive soil moisture, safe and efficient herbicides should be selected and closed and stem and leaf treatments should be conducted to avoid poor weed control or phytotoxicity.
