Cultivation layer soil stripping and reuse method

Abstract

The invention provides a soil stripping and reuse method for plowing layers. The methods include: collecting soil information of the soil-borrowing area, determining the soil quality and soil thickness of the soil-borrowing area according to the collected soil information; classifying soil according to the determined soil quality and soil thickness; soil transportation and soil covering. Further, in the embodiment of the present invention, before covering the soil, the soil restrictive information of the soil covering area is collected, and the soil quality and covering soil thickness of the soil covering area are determined according to the collected soil restrictive information; and when covering the soil: the soil obtained from the soil extraction step The soil quality is selected as the soil that needs to be covered with soil, and the thickness of the covered soil is the determined thickness of the covered soil. The embodiment of the present invention can improve the soil quality of the plow layer soil and ensure the reutilization rate of the plow layer soil resources.

Description

technical field [0001] The invention relates to the technical field of soil reuse, in particular to a soil stripping and recycling method for plowing layers. Background technique [0002] The soil thickness of the plow layer of cultivated land is generally between 20 and 30 cm. It is rich in nutrients, and the roots of crops are dense and in a granular structure. They are the essence of the land and the most basic conditions to ensure high and stable yields of crops. Once the plow layer soil is lost, the regeneration speed will be very slow and has a certain degree of non-renewability. Therefore, when the arable land is occupied, for example: land occupied by non-agricultural construction, the topsoil of the occupied arable land should be stripped for new arable land, poor quality or The soil improvement of other cultivated land can preserve and reuse the precious cultivated layer soil, which is of great value to improve the quality of cultivated land and the ecological envi...

AI Technical Summary

Problems solved by technology

[0003] However, the existing methods of soil stripping and reuse in the plow layer generally only include three steps of soil extraction, soil transportation and soil covering, and generally use rough soil extraction methods in the soil extraction process, which is very easy to cause damage and waste of soil resources
