Seeding method of maize by pushing stubble and clearing ridges and rotary tillage

Abstract

The invention provides stubble-pushing row-cleaning, rotary tillage and sowing technology for corns, pertaining to the technical field of crop cultivation. The stubble-pushing row-cleaning, rotary tillage and sowing technology is characterized in that in a previous crop land parcel where straw is accumulated, stubble-pushing and row-cleaning, deep fertilizing, single-grain precise sowing operation are carried out within rows of sowing belts; in association with water spraying and medicine-spraying operation, multiple operation processes such as deep-rotating, soil-loosening and straw mulching are performed among sowing belts and are completely one time mechanically. The stubble-pushing and row-cleaning technology is performed in such a manner that preceding straw are cut off and crushed at seeding strips and pushed out of sowing belts to stay at non-sowing belts; and meanwhile, shallow rotary tillage at the depth of approximate 10 cm is performed in form seeding strips in sowing belts having no straw or few straw and loose surface soil. The stubble-pushing, row-cleaning, rotary tillage and sowing technology for corns has following beneficial effects: due to the fact that stubble-pushing and row-cleaning operation is used in conjunction with technology such as deep rotary tillage, deep fertilizing and precision sowing, simplified and highly-efficient plantation technology featuring low power consumption and high yield of corns is formed so that difficulties for corn production such as accumulation of preceding straw, poor sowing quality, a solid plow sole of a plough layer and low populations uniformity are effectively solved.

Description

Technical field: [0001] The invention belongs to crop cultivation and cultivation techniques, in particular to a method for pushing stubble and clearing ridges and rotary tillage and sowing of corn. Background technique: [0002] In my country, the planting of both spring corn and summer corn is faced with poor sowing quality due to the large amount of straw in the previous stubble, uncontrollable straw burning in the field, serious air pollution and fire losses. Unstable performance leads to lack of seedlings and broken ridges, which seriously restricts the development of local corn production. At present, the technology of no-tillage direct seeding or deep plowing of straw is adopted to solve the problem of straw, but it causes serious pests and weeds. To solve the problem of the solid bottom of the plow layer, the deep loosening shovel is used to carry out a single operation, but it requires a large-horsepower tractor. It consumes a lot of energy, and the deep loosening e...

Problems solved by technology

[0003] The purpose of the present invention is to simultaneously complete the steps of stubble pushing and ridge clearing, deep spin loosening, deep fertilization, precision sowing and other links in one operation, effectively solving the problems of straw accumulation in the previous stubble, poor sowing quality, shallow plowing layer with solid bottom layer and low group uniformity In order to solve the difficult problems of corn production, a light and simplified planting method with low energy consumption, high yield and high efficiency has been formed.
