Problems solved by technology

The currently promoted straw composting technology is labor-intensive and time-consuming, and the composting effect is poor, so farmers rarely use it
The methods promoted by the government to dispose of straw through mechanical stubble removal + no-tillage mulching or plowing and returning to the field also have many derivative problems, such as reduced quality of plowed land, impact on mechanical tillage, and aggravation of pests and diseases, etc.
In addition, straw is difficult to crush in the field, and it is not easy to decompose after returning to the

Embodiment 1

[0029] A method for returning compost to the field in a dry land with partial rest and composting in the field, comprising the following steps:

[0030] S1. For a certain field, such as figure 1 As shown, the field 10 in the field block is divided into a recuperation area and a cultivation area 11; in each planting season, all straws in this field block are collected into the rest area of ​​this field block, and composted in the rest area for raising land, and crops are planted in the cultivated area of ​​the field, and the manure heap 12 in the recuperation area is as figure 1 as shown, figure 1 The cultivation area 11 in the middle is located in the middle of the field 10, and the recuperation area is located on both sides of the field 10.

[0031] The recuperation area is a strip-shaped area, for example, the width of the recuperation area is set to 2 meters, and the recuperation area is distributed along the length direction of the field. The recuperation area in the st...

Embodiment 2

[0042] The method in embodiment 2 is basically the same as the method in embodiment 1, and the difference is that the recuperation area in embodiment 2 is located in the middle of the field 10, so the compost heap 12 built on the recuperation area is also in the middle of the field 10, And the cultivation area 11 is located on both sides of the field 10 .

Abstract

The invention relates to a method for returning straws to a dry field through partial rotational planting and composting. The method comprises the following specific steps: S1, for a certain field, dividing the field into a rest area and a planting area; in each planting season, gathering all straws in the field to the rest area, composting the straws in the rest area for land maintenance, while planting crops in the planting area of the field; S2, in the first planting season after land maintenance, directly returning a compost as an organic fertilizer into the field, and then resetting the rest area and the planting area of the field, wherein the rest area and the planting area set in the planting season are different from those set in the planting season before land maintenance. By the method, the problem of sustainable operation of returning the straws to the field is creatively solved, rotational planting and composting for soil improvement is achieved, the negative effect of returning the straws to the whole field is avoided, the effects of improving the soil fertility and increasing organic matters in soil are significant, and the cost of grain production is significantly reduced.

Description

technical field [0001] The invention specifically relates to a method for composting and returning straw to the field in a partial rotation in the dry land field. Background technique [0002] The problems of rice, wheat, corn and other straws, and organic wastes such as livestock and poultry manure have always plagued the development of modern agriculture. The currently promoted straw composting technology is labor-intensive and time-consuming, and the composting effect is poor, so farmers seldom use it. The methods promoted by the government to dispose of straw through mechanical stubble removal + no-tillage mulching or plowing and returning to the field also have many derivative problems, such as reduced quality of plowed land, impact on mechanical tillage, and aggravated pests and diseases. In addition, straw is difficult to crush in the field, and it is not easy to decompose after returning to the field. In addition, the allelopathic effect of straw causes difficulty i...
