Tillage-free method for directly seeding winter wheat into dry-land mulching film cornfield

Abstract

The invention discloses a tillage-free method for directly seeding winter wheat into a dry-land mulching film cornfield. Corns are subjected to hole sowing at proper time after fertilization, deep tillage, raking, chemical herbicide spraying and mulching film coverage are executed according to requirements of direct seeding of winter wheat in a tillage-free manner in the spring; after the corns are harvested in the autumn, the corn straws are cleared away, and the mulching film is retained, so that the winter wheat can be directly subjected to hole-sowing on the mulching film in the tillage-free manner. The tillage-free method for directly seeding winter wheat into the dry-land mulching film cornfield has the beneficial effects that density resistance and high yield mid-maturation and early-maturation corns are selected; after the corns are harvested, the soil work is reduced, and the winter wheat can be sowed at proper time; the soil water content and the ground temperature are increased when the winter wheat is sowed after the corns are harvested; seedlings are tidy consistently and grow robustly; after the corns are sowed in a full-film double-ridge trench, and the tillage-free directly sowed winter wheat can be sowed on the ridges, so that the surface area of the soil is enlarged, and the light capturing amount is increased; the phenomenon of low ventilation and light transmittance property of conventional flat planting is well avoided; the yield and the benefit are increased; the effect is obvious.

Description

technical field [0001] The invention relates to a method for planting crops, in particular to a method for direct-seeding winter wheat without tillage in a cornfield with plastic film on dry land. Background technique [0002] The crop rotation can balance the nutrients in the soil, and can effectively solve the problems of serious diseases, insect pests and weeds, and yield reduction caused by continuous cropping for too long. Reverting winter wheat after spring maize is one of the main crop rotation methods in the semi-humid and arid areas of the Loess Plateau. [0003] Due to the significant moisture conservation and yield-increasing effect of plastic film covering, in recent years, film-covered rain-harvesting agriculture has rapidly emerged in Gansu, Ningxia, Shanxi, Shanxi and other provinces, especially film-filmed corn. The area of ​​corn reached more than 10 million mu. In the semi-humid and arid areas of the Loess Plateau, the planting area of ​​winter wheat afte...

AI Technical Summary

Problems solved by technology

At the same time, autumn harvesting (corn harvesting) and autumn sowing (winter wheat planting) agricultural activities are highly concentrated, and the labor force is tight. The current low-efficiency, time-consuming, and labor-intensive winter wheat production technology cannot meet the high-efficiency requirements of winter wheat production in the semi-humid and arid areas of the Loess Plateau. , The urgent need for cost-saving cultivation techniques
