Row tilling and sowing agricultural mechanized production method

Abstract

An agricultural mechanization production method of drill tillage and drill sowing, relating to an agricultural mechanization production process, belonging to agricultural technique field, sowing on the loose soil which is drill-tillage. The invention can realize straw-return to -field once-for-all by mechanical device, avoiding the shortcoming of nitrogen adsorption influencing the product yield because of the mechanical full-scale straw-return to-field; reducing the water evaporation from arid area and incidence rate of soil and water loss and sand storm, lightening the extent of injury by sand storm, and generating little damage to surface soil; reducing the irrigation water consumption in arid area, slowing down the descent rate of groundwater; being good for keeping geothermal for hydrographic net area, preventing wheat frost-damage; saving greatly tillage energy consumption and reducing planting cost. Straw-return to -field can be carried out in all the rice-producing area, which prevents soil from further hardening and avoids wasting soil organic matter by burning straw.

Description

technical field [0001] The invention relates to an agricultural mechanized production process and belongs to the field of agricultural technology. Background technique [0002] At present, there are three technological schemes for mechanized rice and wheat straw returning to the field. One is to use the reverse stubble cutter to turn the straw discharged from the tail of the combine harvester into the whole stalk and reverse rotary tillage to bury the stubble; the second is to use the harvester with a crushing device. First, crush the discharged stalks and then use the rotary tiller to bury the stubble; the third is to take off the combined harvester before cutting and sprinkle the straw in the field after harvesting, and then use the rotary tiller to bury the stubble. Existing mechanized seeding technology has the following representative three kinds: ① deep plowing + crushed soil + drilling (three operations); ② shallow plowing and drilling (one operation); ③ shallow loose...

AI Technical Summary

Problems solved by technology

Above-mentioned ①, ② kind of technology adopts the method of full tillage, is unfavorable for returning straw to the field and protecting overwintering vegetation and topsoil to prevent sand damage. Although the third method has the advantages of protecting overwintering vegetation and topsoil, its disadvantage is that it consumes Excessive work and entanglement of grass are not conducive to the full amount of straw returning to the field and saving costs and consumption
