Spring corn and winter soybean interplanting method

Abstract

The invention discloses a spring corn and winter soybean interplanting method. The spring corn and winter soybean interplanting method comprises the steps of preparation of culture beds, appropriate-period sowing, rational close planting, increased application of phosphatic fertilizer and field management. According to the spring corn and winter soybean interplanting method, winter soybean which is long in growth period and high in shade tolerance during the seedling stage is planted in early summer to ensure that the vigorous growth period is in August, September of October each year, namely,months after corn is harvested, thereby being low in symbiotic opposition to the corn; the winter soybean is interplanted in corn fields without occupying arable fields and avoid field conflict between the soybean and other crops, so that without influence on corn production, the yield per mu (=0.0667 hectares) of the soybean can be increased by 30-50 kilograms, and further crop productivity canbe enhanced.

Description

technical field [0001] The invention belongs to the field of agricultural product planting, and more specifically, the invention relates to a method for interplanting spring corn and winter soybean. Background technique [0002] Intercropping intercropping is a measure to increase production in agriculture. Intercropping intercropping can rationally allocate crop groups, make crops high and short in layers, and line up alternately, which is conducive to improving the ventilation and light transmission conditions of crops, increasing the utilization rate of light energy, and giving full play to the advantages of side rows. Yield-increasing effect; intercropping refers to the planting method of planting different types of crops in different proportions on the same land; intercropping is to use the spatial structure principle of the community to make full use of light energy, space and time resources to increase crop yield; soybean is a food, economic , feeding ternary crops, i...

[0002] Intercropping intercropping is a measure to increase production in agriculture. Intercropping intercropping can rationally allocate crop groups, make crops high and short in layers, and line up alternately, which is conducive to improving the ventilation and light transmission conditions of crops, increasing the utilization rate of light energy, and giving full play to the advantages of side rows. Yield-increasing effect; intercropping refers to the planting method of planting different types of crops in different proportions on the same land; intercropping is to use the spatial structure principle of the community to make full use of light energy, space and time resources to increase crop yield; soybean is a food, economic , feeding ternary crops, important raw materials for animal husbandry and food industry, winter soybeans have a long growth period, simple planting, long land occupation time, low land utilization rate, and it is difficult to increase crop productivity; single crop planting, for water, fertilizer The utilization rate is low, and it is easy to cause large-scale pests and diseases
