Abstract

The invention discloses an improvement and use method of a saline and alkaline land. The method comprises the following steps: collecting soil on the surface layer of the saline and alkaline land; carrying out improvement treatment on the saline and alkaline land subjected to removal of the soil on the surface layer to obtain an improved land; constructing an agricultural greenhouse on the improved land by using the collected soil on the surface layer as at least part of a wall body; and installing a solar battery on the wall body for generating power. According to the method, the agricultural greenhouse and photovoltaic power generation are combined, so that the problem of land utilization of a photovoltaic power generation facility is solved, and economical crops can be planted in the agricultural greenhouse; and solar power generation and the economical crops can both achieve economical benefits.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for improving and utilizing saline-alkali land. Background technique [0002] There are a lot of saline-alkali land in the arid and semi-arid areas of northern my country. This inland saline-alkali land is caused by the fact that the annual rainfall is far less than the evaporation. The high salt content in the saline-alkali soil makes most plants unable to survive, so large areas are barren. Due to the lack of plant coverage, sand and rocks will fly when encountering severe weather such as strong winds. [0003] How to improve and utilize saline-alkali land remains to be studied. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the present invention is to propose a method for improving and utilizing saline-alkali land. This method combines agricultural gre...
