Embodiment

[0038] The saline-alkali land to be improved is located in the northwest of Hebei, with a soil pH of 8.6, an alkalinity of 18%, and a salt content of 1.0%. First level the saline-alkali land, and then spread calcium-based soil conditioner. The calcium-based soil conditioner used includes: 85 parts by weight of desulfurized gypsum, 6 parts by weight of straw, 5 parts by weight of biomass coke, 4 parts by weight of weathered coal, 0.1 part by weight of urea, and 0.05 parts by weight of microbial bacteria Fat. The application rate is 2000kg / mu.

[0039] Soil deep loosening and rotary tillage treatment. The depth of soil loosening is 50 cm, and the depth of soil rotary tillage is 20 cm, so that it can be fully mixed with calcium-based soil conditioner.

[0040] Subsequently, oats and pigtails were planted on saline-alkali soil.

[0041] Lay multiple rows of solar panels. The inclination angle of the solar panels is 39 degrees. The distance from the vertical projection of the f...

Abstract

The invention discloses an inland saline-alkali soil ecological restorative method. According to the inland saline-alkali soil ecological restorative method provided by the embodiment of the invention, the method comprises the steps that (1) vegetation is planted on the surface of saline-alkali soil; and (2) solar panels are laid on the saline-alkali soil where the vegetation is planted. The deserted saline-alkali soil serves as a photovoltaic power generation field in order to solve the land problem for photovoltaic power generation equipment; and because of shielding of the solar panels, growing-up of the vegetation is facilitated, vegetation coverage also prevents sand and stone flying in strongly windy weather, and the service life of the solar panels can be prolonged.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for ecological restoration of saline-alkali land, and more specifically, to an ecological restoration method for inland saline-alkali land. Background technique [0002] There are a large number of saline-alkali lands 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. Due to the lack of plant coverage, sand and rocks will fly when encountering severe weather such as strong winds. [0003] Therefore, the current ecological restoration methods for inland saline-alkali land still need to be improved. Contents of the invention [0004] This application is based on the inventor's discovery and recognition of the following facts and problems: [0005] At present, most of the resto...
