Description

Administer soil salinization protection blanket laying device Technical Field The invention belongs to the field of agricultural machinery, and particularly relates to a protective blanket laying device for treating soil salinization. Background Soil salinization is a process in which salt of the bottom layer of soil or groundwater rises to the surface of the earth along with capillary water, and after water is evaporated, the salt is accumulated in the surface layer soil. The Chinese salty soil has wide distribution range, large area and multiple types. The soil salinization problem is a great challenge facing Chinese agriculture, and severely restricts the development of Chinese agricultural production. The main treatment methods of the saline-alkali soil at the present stage can be roughly divided into four categories of improvement of water conservancy, improvement of agricultural measures, biological improvement and chemical improvement. Although the existing methods and research results are used for researching the saline-alkali soil treatment problem from different starting points, the method and the research results have corresponding limitations, such as adverse water conservation due to water conservancy measures, construction of a large number of drainage ditches and supporting facilities, and the chemical method and the biological method can only be used for carrying out targeted treatment on special saline-alkali soil and easily cause secondary pollution of soil. One of the physical improvement schemes for treating the soil salinization protective blanket has good applicability in the large-area soil salinization treatment, but no special laying device exists in China at present. In order to recover the productivity of the salinized land as much as possible, and achieve the effects of economy, environmental protection and no secondary damage. What is needed is a mechanism for smooth placement of a protective blanket to achieve the following: 1) Short acting period and obvious effect. 2) The application range is wide, and the method is suitable for various scenes. 3) Not only can change the salinization of the soil in a short period, but also can improve the soil structure of the surface layer of the saline-alkali soil.
