Wheat-corn ridge-culture zero-tillage direct-sowing cultivating method

Abstract

The present invention relates to a wheat-maize ridge-planting non-tillage cultivation method by direct seeding. Said method uses special-purpose ridge drill for wheat to making ridge forming and ridge sowing, after the wheat is harvested, the straw can be covered with surface layer, and the special-purpose sowing machine for maize can be used for sowing on the ridge, so that it is favorable for high-yield of maize.

Description

Technical field: [0001] The invention relates to a planting method of two main field crops, in particular to a ridge-planting no-tillage direct-seeding cultivation method of wheat to corn. Background technique: [0002] The existing wheat-corn crop rotation system mainly adopts flat cultivation, and corn is interplanted before wheat harvest. This kind of planting system mainly has the following five disadvantages: first, it cannot realize the whole process of mechanized operation, and the labor productivity is low; second, it cannot guarantee the density and uniformity of corn, which affects the yield of corn; Premature aging reduces grain weight and reduces yield; fourth, interplanting corn is harvested early, and there is generally a crop rotation period of about 20 days from corn harvest to wheat sowing, and this period is the end of the rainy season and the temperature is relatively moderate, which is most conducive to corn grain filling Timing, so corn interplanting wa...

Problems solved by technology

This kind of planting system mainly has the following five disadvantages: first, it cannot realize the whole process of mechanized operation, and the labor productivity is low; second, it cannot guarantee the density and uniformity of corn, which affects the yield of corn; Premature aging reduces grain weight and reduces yield; fourth, interplanting corn is harvested early, and there is generally a crop rotation period of about 20 days from corn harvest to wheat sowing, and this period is the end of the rainy season and the temperature is relatively moderate, which is most conducive to corn grain filling Timing, so corn interplanting wastes light and heat resources, which is not conducive to a balanced increase in production throughout the year; fifth, the traditional farming system (after corn is harvested, before wheat sowing requires plowing, harrowing, etc.) not only increases production costs, but also destroys soil structure and soil benefits. The living environment of organisms is not conducive to the stability of biodiversity and agricultural ecosystems
