Embodiment 1

[0028] A soil improver for saline-alkali land, comprising 10 parts of chemical fertilizers (including urea, superphosphate and potassium sulfate), 120 parts of vermicompost, 51 parts of humic acid, 500 parts of gypsum, and 0.25 parts of mixed bacterial agent. The above-mentioned raw materials are taken according to the proportioning ratio and mixed according to conventional methods in the prior art.

Embodiment 2

[0030] A soil improver for saline-alkali land, comprising 1 part of chemical fertilizer (including urea, superphosphate and potassium sulfate), 10 parts of vermicompost, 5 parts of humic acid, 50 parts of gypsum and 0.01 part of mixed bacterial agent. The above-mentioned raw materials are taken according to the proportioning ratio and mixed according to conventional methods in the prior art.

Abstract

The invention relates to a saline and alkaline land soil conditioner. The saline and alkaline land soil conditioner comprises, by weight, 1-15 parts of a chemical fertilizer, 10-150 parts of wormcast, 5-60 parts of humic acid, 50-650 parts of gypsum and 0.01-0.3 parts of a mixed microbial agent. The saline and alkaline land soil conditioner is especially suitable for coast middle saline and alkaline land soil, and is applied according to a dosage of 3000-4000 kg / hm<2>. The pH value of saline and alkaline land processed with the soil conditioner is reduced by 0.11 or above, the content of organic matters in soil of the saline and alkaline land processed with the soil conditioner is improved by 6.5-12.3%, and the yield of crops growing in the saline and alkaline land processed with the soil conditioner is increased by 13.8-39.9%.

Description

technical field [0001] The invention relates to the technical field of saline-alkali soil improvement, in particular to a saline-alkali soil improvement agent and its preparation method and application. Background technique [0002] Saline-alkali soil is under the joint action of various natural environmental factors and human activity factors, causing the accumulation of saline-alkali components in the soil, and components such as salts and alkalis directly participate in the formation process of the soil, thus making the soil salinized. The layer or alkalization layer makes the soil contain a large amount of soluble salts, thus forming a soil that is not conducive to the normal growth of crops. The problem of soil salinization and soil secondary salinization caused by human factors has been widespread all over the world, which poses a great threat to the long-term development of human beings and the sustainable development of agriculture. According to statistics from the ...
