Corn stubble-remaining ridge side planting method

Abstract

The invention relates to a stubble-leaving ridge side planting method pertaining to a technical field of corn planting and cultivation. A stubble of 5-15cm is left in even ridges of the existing tillage method after corn harvest, and seeds are sowed at a side of the ridge containing the stubble in the next year. One plough is shallowly processed on the side of a stubble belt of the last year, andthen base fertilizer is applied. The seeds in precision quantity are manually sowed by using a disseminator and then grain fertilizer is applied. Soil is covered on the seeds and compacted to conserve soil moisture. The stubble-leaving ridge side planting method for corn of the invention realizes safely returning of straws, little move of soil, soil moisture conservation and seedling protection. Combined with dressing, subsoiling is used for breaking plough pans to create soil reservoir of plough layers, improve the use efficiency of natural rainfall, realize natural decay and returning of high stubbles, increase soil organic matters and cultivate fertility, thus ensuring the sustainable use of land resource.

Description

Corn stubble side planting method technical field The invention belongs to the cultivation technique of corn. Background technique Among the existing field crop cultivation techniques, most countries with developed economy and suitable climate conditions adopt mechanical harvesting, straw crushing and returning to the field for mechanized cultivation. There are two main methods of cultivation in Northeast my country: one is to turn and rake to form an even ridge of 60-70 cm; broadcast. The main disadvantages of the first method are that there are many operation steps and high cost, and the soil moisture will be lost in a large amount in autumn and spring, which will aggravate the drought; the second is that it is difficult to return the straw to the field safely, and the soil below 20cm forms the plow bottom layer, which has poor permeability . The second method is the method of plowing into ridges and sowing seeds on the ridges after stubble removal, which belongs to t...

Problems solved by technology

During mechanical operations, the field is rolled too many times, the soil bulk density increases, the ability to resist natural disasters is low, and the yield is not high and unstable

The labor intensity is high and the labor productivity is low when working with human and animal power
