Wheat-spinach-corn-green mature intercropping planting and cultivating method

Abstract

The invention relates to a wheat-spinach-corn-green mature intercropping planting and cultivating method. The method comprises the following steps: performing first-time land preparation; sowing winter wheat and spinach; performing weeding and disinsection; harvesting the spinach, irrigating the wheat after turning green, and planting spring corn; harvesting the winter wheat, and planting summer corn; applying corn fertilizers; irrigating the corn, performing weeding, and controlling pests and diseases; harvesting the spring corn, sowing green manure plants, performing second-time land preparation, and plowing the green manure plants into land; performing alternate planting between a spring corn belt and wheat belt, and repeating the planting steps. According to the method, intercropping cultivation is performed on five plants including the winter wheat, the spinach, the spring corn, the summer corn and the green manure, which not only conforms to cultivation habits of the five plants,but also makes full use of mutually beneficial relationships between different plants to form a reasonable composite population structure; various stress resistances of populations are improved; thesoil disease phenomenon under a single crop rotation mode is avoided; the quality of soil and cultivated land is improved; and the defects that benefits gained by only planting grain are low, sustainable production capacity of the soil is low, and the like are remedied.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and in particular relates to a wheat-spinach-corn-green manure intercropping cultivation method. Background technique [0002] The traditional intercropping mode mostly relies on manual planting, which has high labor intensity, low economic benefits and is not conducive to the development of mechanization, which seriously restricts the process of agricultural mechanization in this area and discourages farmers' enthusiasm for farming. [0003] In terms of crop planting, single-cropping and continuous cropping are the traditional planting patterns. Single-cropping and continuous cropping are likely to cause heavy cropping. Changing cropping and intercropping are effective ways to overcome heavy cropping. However, winter wheat is the only two-year crop that survives the winter. It is sown in early October every year, and matures and harvests in early June of the second year after ov...

Problems solved by technology

[0005] The above patent application documents use wide and narrow rows, which is not conducive to mechanized operations. At present, mechanized sowing and mechanized harvesting of wheat and corn have been basically realized. Failure to implement mechanized operations will seriously affect production efficiency and is not suitable for large-scale planting.
