Problems solved by technology

In the past work, more emphasis was placed on engineering measures. Although some achievements have been made, there are still some insurmountable shortcomings: (1) The engineering cost is expensive, and the effect is not long-lasting. After washing with fresh water, the nutrients in the soil are discharged together with the salt , fresh water resources are insufficient, and it is difficult to meet the demand for salt pressure; (2) Although salt-tolerant plants have been initially screened, there is no systematic classification of plant species that can meet various types of saline-alkaline land, and the cultivat

Abstract

The invention relates to a Ca<2+> signal transduction saline-alkali modifier and a mixture ratio of raw materials. The Ca<2+> signal transduction saline-alkali modifier is specially used for modifying chloride saline-alkali lands, sulfate saline-alkali lands and carbonate saline-alkali lands. The related technology comprises the steps of selection of raw materials, crushing, sieving, weighing, mixing, stirring and subpackaging of finished products. The mixture ratio of raw materials is as follows: 0.1 to 0.2 percent of calcium signaling molecules, 1 to 2 percent of paclobutrazol, 0.5 to 5 percent of high molecular polymers, 6 to 40 percent of humic acid, 10 to 30 percent of phosphogypsum, 10 to 70 percent of zeolite powder (between 60 and 80 meshes), 25 to 30 percent of calcium superphosphate, 20 to 40 percent of fermented cow manure, 5 to 10 percent of nitrogen phosphorus potassium, 1 to 2 percent of ferrous sulfate and proper amount of vermiculite. The Ca<2+> signal transduction saline-alkali modifier aims to improve the utilization rate and the economic value of the chloride saline-alkali lands, the sulfate saline-alkali lands and the carbonate saline-alkali lands.

Description

1. Technical field [0001] The present invention relates to a Ca 2+ The preparation process and composition ratio of the signal transduction type saline-alkali modifier are specially used for the transformation of chloride-type, sulfate-type and carbonate-type saline-alkali land, so as to facilitate the recovery and utilization of the above-mentioned saline-alkali land. 2. Background technology [0002] The improvement of saline-alkali land is a worldwide problem. The global saline-alkali land area is about 15 billion mu, my country's arable land is only 1.5 billion mu, and the saline-alkali land area is about 540 million mu, of which the saline-alkali cultivated land reaches 90 million mu, which has become the biggest obstacle to my country's ecological environment construction and sustainable agricultural development. . At the same time, with the reclamation of a large area of ​​land, soil salinization caused by unreasonable irrigation and deterioration of water quality is...
