Conservation tillage method for total returning of maize straws in rows

A corn stalk and protective technology is applied in the field of protective farming where the corn stalk is returned to the field in full, which can solve the problems of underutilized agricultural crop resources, many corn planting and production links, difficulty in ensuring the quality of sowing, and the like, so as to increase production. Significant income increase, beneficial to soil fertility, and significant social benefits

Problems solved by technology

[0002] In recent years, straw incineration has been widely used in corn planting, which has seriously polluted the environment, caused soil compaction, decreased microbial content, and a large number of agricultural crop resources have not been fully utilized.
Using a no-tillage seeder to sow without-tillage under the conditions of corn stalk stubble and a small amount of straw mulch reduces the burning of corn stalks; however, once the amount of straw mulch exceeds one-third, it brings problems to mechanical no-tillage sowing, which is difficult Guarantee the quality of sowing
At the same time, there are many links in corn planting and production, and machinery repeatedly enters the field, resulting in high costs. In the current situation of low corn prices, reduce the cost of corn production, improve the benefits of corn planting, and point out the direction for farmers to solve problems is an urgent issue

Embodiment 1

[0022] Maize is planted in a wide and narrow row rotation pattern of conservation tillage, such as figure 1 As shown, in the autumn of the first year, the corn combine harvester is used for harvesting, the straw crushing device is turned on, and the straw is crushed and sprayed evenly on the field at the same time as harvesting. The stalks are collected to the planting row (with stubble) of the first year, and the fallow row of the first year is left for planting corn in the second year and overwintering. In the spring of the second year, after a winter of wind blowing and livestock trampling, some of the stalks returned in the fall of the first year were scattered on the sowing belt of the second year. Therefore, in the spring of the second year, the tractors carried forward The built-in straw return machine can thoroughly clean up a small amount of straw on the sowing belt, so that it will not have any impact on the sowing, and the no-tillage seeder will go into the field at...

Embodiment 2

[0024] Such as figure 2 As shown, the corn is planted in the rotation pattern of wide and narrow rows (wide row 900mm, narrow row 400mm) of conservation tillage, and the crushed straw in the autumn harvest of the first year is collected to the planting row of the first year (400mm wide) by the straw returning machine. ), clear the sowing belt and reserve it for no-till sowing corn in the second year. Such as image 3 As shown, in the second year, the leisure row (900mm) of the first year is cleaned out and becomes the sowing belt (400mm wide) of the second year, and the straw is gathered on the sowing belt of the first year (with a width of 400mm) by the straw returning machine. There are root stubbles, 400mm wide), the sowing belt in the first year becomes the leisure row in the second year, the straw is placed alternately, and the sowing belt is alternately rotated. Through the action of wind, sun, rain and soil microorganisms, the straw is gradually reduced and returned ...

Abstract

The invention relates to a method for planting crops, in particular to a conservation tillage method for total returning of maize straws in rows. According to the planting method, uniform straw coverage of conservation tillage of maize wide / narrow-row rotation is changed into in-row operation employing a straw rowing machine, and planting seedling strips are exposed out of the earth surface, so that sowing operation of a no-tillage planter is facilitated; the sowing effect is greatly improved; and the seedling rate is ensured.

Description

technical field [0001] The invention relates to a planting method of crops, in particular to a protective tillage method in which corn stalks are returned to the field in full amount. Background technique [0002] In recent years, straw burning has been widely used in corn planting, which has seriously polluted the environment, caused soil compaction, decreased microbial content, and a large number of agricultural crop resources have not been fully utilized. Using a no-tillage seeder to sow without-tillage under the conditions of corn stalk stubble and a small amount of straw mulch reduces the burning of corn stalks; however, once the amount of straw mulch exceeds one-third, it brings problems to mechanical no-tillage sowing, which is difficult Guarantee the quality of sowing. At the same time, there are many links in corn planting and production, and machinery repeatedly enters the field, resulting in high costs. In the current situation of low corn prices, reduce the cost...
