A saline-alkali land greening module and a saline-alkali land greening method

Abstract

The invention discloses a saline-alkali soil greening module and method, and belongs to the technical field of saline-alkali soil greening. The saline-alkali soil greening module is characterized in that the saline-alkali soil greening module comprises an upper module body and a lower module body, the upper module body is formed by connecting an outer wall A, a top plate and an upper weight bearing column fixed onto the top plate, the lower module body is formed by connecting an outer wall B, a base plate and a lower weight bearing column fixed onto the base plate, and the upper module body is connected with the lower module body in a matched mode. The saline-alkali soil greening method comprises the following steps that saline-alkali soil is leveled and drainage channels are excavated, wherein the drainage channels which are staggered longitudinally and transversely are arranged at the interval of 1-50m; modules used for planting plants are laid, the adjacent modules are connected in a clamping and matching mode through concave connecting buckles and convex connecting buckles, and the row of modules near the drainage channels enable drainage pipes to be directly connected into the drainage channels; ground cloth is laid on the modules, matrixes are laid on the ground cloth and the plants are planted on the matrixes. The saline-alkali soil greening module and method have the advantages of being low in cost, fast in construction, long in service time, good in modification effect and the like.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land greening, and specifically relates to a saline-alkali land greening module and a saline-alkali land greening method. Background technique [0002] Saline-alkali land refers to land plots that have a large amount of soil salt accumulation due to differences in geological structure formation conditions, which have a direct impact on planting plants. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country, and there is a tendency to continue to expand. Vinocour et al. (2005) predicted that by 2050, more than 50% of cultivated land would be salinized, and the improvement and management of saline-alkali land is urgent. In afforestation, saline-alkali land is generally divided into mild saline-alkali land (salt content<0.3%), moderate saline-alkali land (0.3%≤salt ...

AI Technical Summary

Problems solved by technology

[0003] In view of the above-mentioned problems existing in the prior art, the object of the present invention is to design and provide a saline-alkali land greening module and a technical scheme of a saline-alkali land greening method, by using a plant planting module, with the purpose of salt resistance, to solve the problems of the prior art The medium-saline land device is not suitable for large-scale greening, and the water storage part is easy to accumulate silt. It has the advantages of low cost, fast construction, long service life, and good transformation effect.
