Abstract

The invention provides a method for collecting rainwater by adopting a water storage layer containing diatomite and an application thereof in saline-alkali soil improvement. The method for collecting rainwater comprises the step of laying the water storage layer which comprises the following raw material components: the diatomite, ceramsite, water-absorbent stone, asbestos powder, cottonseed hull, swarf lilyturf powder, elm bark powder, high-substitution-degree crosslinking carboxymethyl cellulose, walnut shell powder, and furnace ash and slag, wherein the diatomite has a particle size of 3 to 3.5 mm. According to the invention, after the saline-alkali soil is improved by adopting the method provided by the invention, the soil has a humus content of 2.46 to 2.65%, an effective nitrogen content of 235 to 242 mg / kg, an effective phosphorus content of 5.7 to 5.9 mg / kg, and an effective potassium content of 124 to 138 mg / kg.

Description

technical field [0001] The invention relates to a method for collecting rainwater by using an aquifer containing diatomite and its application in improving saline-alkali land, belonging to the technical field of soil improvement. Background technique [0002] The area of ​​saline-alkali land in my country is 99.13 million hectares. Most of the formation of alkaline soil and alkalized soil in my country is related to the accumulation of carbonate in the soil. Therefore, the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. [0003] The distribution of salt in the soil in saline-alkali land is more in the surface layer and less in the lower layer, and the growth of plants mainly depends on the soil in the surface layer. [0004] Most saline-alkali soils are distributed in arid and semi-arid regions. The rainfall in these areas is small in spring and winter, and the rainfall is mostly concentrated in the short summer. ...
