Double-cropping straw-returning farming method for wheat and maize

Abstract

The invention discloses a double-cropping straw-returning farming method for wheat and maize, comprising the following steps: (A), lofting a ridge surface; (B), ploughing a ridge furrow; (C), spreading base fertilizer; (D), sowing the maize; (E), returning the wheat straws to the field; (F), furrow deepening and hilling; (G), cleaning the furrow and covering the seeds; (H), managing the field; (I), burying the straws; and (J), ploughing and planting the wheat. Summer maize is planted in the winter wheat stubbles; the method is free of tillage and holes, and rational in close planting; each ridge is sowed in drill in two rows; the wheat straw is covered between the rows of the maize ridge surface; the maize straw is collected in the ridge furrow, buried and returned to the field; the water and soil is conserved; the environment is protected; fertility is collected and water is stored; the fertility is increased and the soil is improved; the production of wheat and maize is stable and high; in a 5-year period, the ridge furrow moves towards the same direction; the ridge surface at the field edge is irregular; other ridge surfaces are standard so that the ploughing layer of the full field can be 30cm deep; the soil organic matters are largely increased so that the method is a farming method for improving middle / low-production field and providing high-production field; and the economic benefits, the social benefits and the ecological benefits are increased.

Description

technical field [0001] The invention relates to a farming method for returning wheat and corn second-ripe stalks to the field. Background technique [0002] Planting summer corn after harvesting winter wheat is an important crop layout for my country's grain production. Wheat and corn stover are versatile renewable biological resources for fuel, feed and fertilizer. Farmers in our country have always had a fine tradition of rationally utilizing and comprehensively developing straw. With the change of people's production methods and the application of liquefied gas and other fuels, there is a large amount of surplus straw in the countryside. At present, the utilization rate of straw resources in my country is low, and most of them are discarded or directly burned, which not only wastes resources seriously, but also causes environmental pollution. [0003] At present, the square hole cultivation method for double-cooking wheat and corn for corn specifically includes the fol...
