Soil conditioner for saline-alkali soil in Xinjiang and preparation method thereof

Abstract

The invention discloses a soil conditioner of Xinjiang saline alkali soil. The soil conditioner is prepared from the following ingredients in percentage by weight: 45 to 55 percent of acidic boric sludge, 30 to 40 percent of potassium fulvate, 1 to 10 percent of chelated zinc and 1 to 8 percent of chelated manganese. The invention aims at providing the soil conditioner of saline alkali soil. The soil conditioner aims at the Xinjiang saline alkali soil improvement; the saline content is reduced; the soil gel adsorption ion composition is changed; the soil structure is improved, so that the soil permeability is improved; the soil desalination and the soil resalinization inhabitation are facilitated; and the nutrient requirements of crops in the saline alkali environment can be met, so that the goal of improving the saline alkali soil is achieved. The invention also discloses a preparation method of the soil conditioner of Xinjiang saline alkali soil.

Description

technical field [0001] The invention relates to the category of soil conditioners, in particular to a soil conditioner for saline-alkali soil in Xinjiang and a preparation method thereof. Background technique [0002] Due to Xinjiang's special climate environment and human farming patterns, a large amount of salt remains in the soil. When the evaporation is much greater than the precipitation, the salt moves with the water and then moves to the soil surface, resulting in a large amount of salt accumulation on the soil surface, forming The so-called saline-alkali land affects the use of soil. [0003] Saline-alkali soil usually has an alkaline pH, high salt content, high sand content, large surface and bottom layers, high water content, and low organic matter content, resulting in a compact structure and low porosity, hindering the migration of water and salt; The saturated hydraulic conductivity of alkaline soil is very low, especially the lower surface and bottom layer, wh...

[0002] Due to Xinjiang's special climate environment and human farming patterns, a large amount of salt remains in the soil. When the evaporation is much greater than the precipitation, the salt moves with the water and then moves to the soil surface, resulting in a large amount of salt accumulation on the soil surface, forming The so-called saline-alkali land, which affects the use of soil

[0003] Saline-alkali soil usually has an alkaline pH, high salt content, high sand content, large surface and bottom layers, high water content, and low organic matter content, resulting in a compact structure and low porosity, hindering the migration of water and salt; The saturated hydraulic conductivity of alkaline soil is very low, especially the lower surface and bottom layer, which affects the effect of salt leaching; the surface and bottom layer of saline-alkali soil have strong water absorption capacity, strong water holding capacity, and weak drainage capacity, which hinders salt leaching

Due to the above characteristics of saline-alkali land, it will cause certain harm to crop root growth, cell membrane structure, stomata opening and closing, nutrient absorption and genetic material, reduce crop resistance, and affect the normal growth of crops
