A soil improving agent for saline-alkali land in south Xinjiang

Abstract

The invention relates to the field of soil improving agents and particularly relates to a soil improving agent for saline-alkali land in south Xinjiang. According to a main technical scheme, the soilimproving agent is prepared from, by mass, 120 parts of soybean cake, 150 parts of cow dung, 200 parts of mushroom residues, 200 parts of straw, 90 parts of Populus euphratica scraps, 80 parts of pineneedles and 80 parts of enzymes. The soil improving agent increases soil organic matters and makes hydrophilicity high and is also suitable for microbe attachment, growth and reproduction, and large-scale microbe reproduction can induce formation of a soil aggregate structure, thus improving hardening, water permeability and air permeability of the saline-alkali land, facilitating crop growth, and reducing influences of salts of dry land on crop roots. The soil improving agent contains a certain amount of the straw which is difficult to decompose, and through ploughing of the soil improving agent into the saline-alkali land, soil looseness is improved, alkali return caused by capillary phenomena is solved, and overall improvement of the soil is facilitated.

Description

technical field [0001] The invention relates to a soil improver for saline-alkali land in southern Xinjiang, belonging to the field of soil improvers. Background technique [0002] Soil salinization refers to the phenomenon or process of soluble salt accumulation on the soil surface. Saline-alkali soil can be divided into pine-salt soil mainly containing sulfate and chloride and alkaline soil mainly containing carbonate. The harm is mainly reflected in the reduction or failure of crops, affecting the growth of vegetation and indirectly causing the deterioration of the ecological environment. [0003] As the largest saline-alkali soil area in China, it is an indisputable fact that Xinjiang has a high proportion of saline-alkali land. Most of the heavily salinized land cannot be used for a long time, which seriously restricts the development of agriculture in Xinjiang. According to statistics, the area of ​​saline-alkali land in Xinjiang reaches 110,000 square kilometers, acc...
