However, the above-mentioned improvement methods have their own advantages and disadvantages. For example, the investment in physical improvement methods such as back-sealing borrowed soil and raising the ground is too large; water conservancy improvement methods such as large-scale land washing cause waste of water reso

Abstract

The invention specifically relates to the technical field of a saline alkali soil conditioner and a preparation method thereof. The saline alkali soil conditioner provided by the invention is prepared by mixing the following raw materials according to a certain ratio: bentonite, humic acid, gypsum, sulfur powder, chitosan, zinc sulfate and sodium naphthaleneacetate. After acting on soil of saline alkali land, the saline alkali soil conditioner can obviously reduce the soil acidity or alkalinity, total salt content and volume weight, thus accelerating the formation of soil aggregates; the soil organic matter content can be greatly increased to improve the soil fertility and regulate crop growth; and finally, by improving the physicochemical property of the soil, the investment is reduced, and the yield and quality of crops are improved. Besides, the preparation method of the saline alkali soil conditioner is simple, environment-friendly and easy to operate.

Description

technical field [0001] The invention relates to the technical field of a saline-alkali soil improver and a preparation method thereof. Background technique [0002] According to the statistics of the Food and Agriculture Organization of the United Nations, the area of ​​saline-alkali land in the world is not less than 954.38 million hectares, of which 99.13 million hectares are in my country. Soil salinization is one of the chronic diseases that seriously restrict the development of agriculture in the world and in China. Among them, my country's Yellow River Delta is close to the Bohai Sea, and saline-alkali land is widely distributed. The area of ​​salinized land is 442,900 hectares. The soil has a high salt content, mainly chloride, and the pH value is above 8.0; the soil bulk density is high (2.03 g / cm3) , its structure is poor, its fertility is low, and it is difficult to carry out agricultural production without improvement and management. Therefore, the effective use ...
