Saline-alkali soil amendment

Abstract

The invention discloses a saline-alkali soil amendment, and relates to a soil amendment. The soil amendment of the invention solves the problem of the waste of land resources caused by a condition that saline-alkali soil is wasted and can not be used throughout the year because only artemisia anethifolia can grow in the saline-alkali soil at present, while other plants can not grow thereon. Besides, the existing saline-alkali soil amendment is mainly prepared from alum which has high cost and poor soil amendment effect. The saline-alkali soil amendment of the invention is prepared by weight percent from aluminum sulfate, ammonium ferrous sulfate and magnesium sulfate, which are mixed, and the weight ratio of the three materials is 1-1.8:1-2:0.2-0.5. The saline-alkali soil amendment of the invention can ensure that crop plants can be planted in the saline-alkali soil; thus, the saline-alkali soil, a wide land resource, can be made good use of. In addition, the saline-alkali soil amendment of the invention has the advantages of low cost and obvious effect of soil amendment.

Description

technical field [0001] The present invention relates to soil conditioners. In particular, it relates to saline-alkali soil amendments. Background technique [0002] At present, the national saline-alkali soil area accounts for about 60% of the country's land area, and the saline-alkali soil is also composed of different salinity or alkaline or saline-alkaline, while the Songnen Plain is famous for its Suda saline-alkali soil. And pH (ESP) is extremely high, and some Soda saline-alkali soil can only grow Artemisia saline-alkali, and other plants can't grow, and saline-alkali soil is barren all the year round and can't be utilized, causes the waste of land resources; Existing saline-alkali soil improver mainly Ming vanadium is used as the main raw material, but the cost of Ming vanadium is high, and the effect of soil improvement is not obvious. Contents of the invention [0003] The present invention solves the problem that the existing saline-alkali soil can only grow Ar...

Problems solved by technology

[0003] The present invention solves the problem that the existing saline-alkali soil can only grow Artemisia japonica, and other plants cannot grow, so that the saline-alkali soil is barren and unusable all the year round, resulting in waste of land resources; while the existing saline-alkali soil improver mainly uses vanadium as the main raw material, and the cost of Ming vanadium is high, and the problem of soil improvement effect is not obvious, a kind of saline-alkali soil improver is provided, and the specific technical scheme to solve this problem is as follows:
