Embodiment Construction

[0020] The corn stalk enrichment and deep return tillage method provided by the present invention comprises the following steps:

[0021] Step 1: Determination of straw enrichment width

[0022] In areas where corn planting is contiguous and suitable for mechanization, the breadth of straw enrichment is determined according to different planting patterns, types of harvesting machinery and planting scale of operators. Generally speaking, the enrichment width of mechanized harvesting is 5.2m (such as figure 1 A).

[0023] Step 2: Polymerize into a belt

[0024] For the enrichment in the eight ridges, the eight-finger disc rake machine is used to gather the straw scattered on the ground in the eight ridges to form a belt in the middle. After enrichment, the straw placement width is 1.5-1.8m (such as figure 1 A).

[0025] Step 3: Crush into the soil

[0026] The air-injection straw deep-layer return machine is used to inject the crushed straw into the ground through three lin...

Abstract

The invention discloses a corn stalk enriching and deep returning tillage method, and belongs to the field of efficient utilization of the corn stalk resource, soil fertilization and environmental protection and restoration. The method comprises the following steps of enrichment width determining, concentration for zonation, crushing for burying, zonal no-tillage sowing and sequential year-by-year deep returning as per zones. According to the tillage method, previous tillage habits such as straw overturning and pressing, covering and sowing are broken through, innovative technologies such as wide enrichment, wind power deep injection, accurate fertilizer preparation, zonal tillage and no-tillage sowing and combinations thereof are adopted, long-pending key problems of wasting the straw resource, polluting the environment due to burning, being short of soil tillage layer organic matter and nutrients, being poor in technical operation continuity and the like are solved, and important theoretical significance and practical value on resource utilization, environmental protection, soil fertilization and crop high yielding are achieved.

Description

technical field [0001] The invention belongs to the field of fertilization and utilization of straw resources, soil fertilization and cultivation, in particular to a corn straw enrichment and deep return tillage method. Background technique [0002] In view of a series of problems such as wide distribution of corn planting, large amount of straw, tight processing time, few professional deep returning equipment, poor functions, and serious lagging technology, the corn straw enrichment and deep returning tillage method is proposed. With this innovative technology, the straw distribution space is compressed as much as possible, the processing time is shortened, and all the straw is enriched and returned to the deep soil layer during the period from corn harvest to arable land freezing. One is to thoroughly solve the problem of straw burning, and the other is to solve the problem of efficient utilization of straw resources. The third is to solve the problem of long-term "hunger...
