Abstract

The invention provides an MCM-loaded modified soil conditioner for saline-alkaline soil, and a preparation method thereof. The soil conditioner is prepared from, by mass, 5-12% of a prefabricated straw slow-release material, 5-20% of citric acid, 3-7% of fulvic acid, and the balance of an MCM material. The MCM-loaded modified soil conditioner further comprises 0-0.05% of vanillic acid, 0-0.1% of polyglutamic acid and 0-0.1% of polyaspartic acid. The raw materials are classified, prepared, treated and compounded, and layer-by-layer progressive coating property is good, so the bonding compatibility among the raw materials is effectively improved; the MCM material is adopted as a main material, and the prefabricated straw slow-release material and an acidity regulator are used as auxiliary materials, so the saline-alkaline soil conditioner is good in resource reusability, low in cost and high in benefit, remarkably improves the pH regulation and desalination of saline-alkaline soil, is strong in sustainable action and long in effective period, has an excellent effect of supplementing and promoting decomposition of soil nutrient components, remarkably improves the tillage capability ofsoil, and is suitable for planting vegetables and crops.

Description

technical field [0001] The invention relates to the technical field of soil improvers, in particular to an MCM-loaded improved soil improver for saline-alkali land and a preparation method thereof. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares. 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. [0003] Among them, Xinjiang is the province with the largest salinized soil area and the most types of salt composition in my country, and is known as the "World Saline-Alkali Soil Museum". ...
