Conditioner for quick desalination of coastal saline soil

Abstract

The invention relates to a conditioner for the quick desalination of coastal saline soil, which comprises organic fertilizer, gypsum powder and polyacrylamide, wherein the application amount of the organic fertilizer is 5 to 10 cubic meters / mu, the application amount of the gypsum powder is 5 to 10 cubic meters / mu, and the application amount of the polyacrylamide is 1 to 1.3 kilograms / mu. Aiming at the special demands of sowing and seedling keeping in a coastal saline and alkaline area, the conditioner for the quick desalination of the coastal saline soil is developed, has the advantages of simple operation during use, local production of raw materials, low cost and quick desalination, can also be used for regulating the moisture and nutrients of the soil, maintaining water and soil nutrients, improving the soil and microenvironment of seeds and improving crop yield, and is a novel nontoxic conditioner for soil liquid manure.

Description

Technical field [0001] The invention relates to a conditioner, in particular to a conditioner used for rapid desalination of coastal saline soil. Background technique [0002] The distribution of saline soil in my country is also very extensive. According to the statistics of the second national soil survey organized by the Ministry of Agriculture, the area of ​​saline soil in my country is 34.67 million hectares (excluding coastal beaches). Among them, 16 million hectares of saline soil, 867,000 hectares of alkaline soil, and 18 million hectares of various types of salinized and alkalized soil. About 6.67 million hectares have been cultivated and planted in 34.67 million hectares of salt collapse soil. It is estimated that there are still about 17.33 million hectares of potential salinized soil in my country. If this kind of soil can be reasonably developed and utilized, it will be a big contribution to my country's guarantee of 1.8 billion mu of arable land. [0003] Existing c...

Problems solved by technology

[0004] The present invention aims at the existing conditioner used for rapid desalination of saline-alkali soil, although it has a certain effect on improving soil salinity, but its cost is high, the operation is troublesome, and it is not easy to be accepted by farmers, especially not suitable for groundwater in coastal saline-alkali areas It can provide a conditioner for rapid desalination of coastal saline-alkali soil due to the shortage of shallow land and frequent up-and-down movement of salinity
