Abstract

The invention provides a method for collecting rainwater by use of a vermiculite water storage layer and an application thereof in saline-alkali land improvement. The method for collecting rainwater comprises a step of paving a water storage layer, wherein the water storage layer comprises the following raw materials: vermiculite, pine bark stone, reed tube stone, corncob powder, pine bark, pampas grass powder, starch grafted sodium acrylate, cocamidopropyl amine oxide, Kanuma soil and expanded perlite. The particle size of the vermiculite is 0.5-0.6mm, the hardness is 1.2-1.4, and the density is 2.4-2.5g / cm<3>. After saline-alkali land improvement, the organic content is 14-18g / kg, the available potassium content is 129-135mg / kg, the ammonium nitrogen content is 20-25mg / kg, and the available phosphorus content is 5.1-5.9mg / kg.

Description

technical field [0001] The invention relates to a method for collecting rainwater by using a vermiculite aquifer and its application in improving saline-alkali land, belonging to the technical field of soil improvement. Background technique [0002] The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. There are more than 99 million hectares of saline-alkali land in our country. Because no suitable improvement method can be found, saline-alkali land is wasted as a very precious land resource. [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 the...
