Embodiment Construction

[0011] Below, the present invention will be further described in conjunction with specific embodiments:

[0012] A biodegradable saline-alkali soil conditioning nutrient, which is a high-polymerization product after microbial metabolism, PGA 50-70%, urea 25-35%, and root promoting agent 5-15%. The mixture is mixed at 1:15 The solution obtained by dissolving and mixing the mixture of the above-mentioned mixture and water at a ratio of 1:15, and the percentages are weight percentages.

[0013] Carry out field soil test after conditioning nutrient preparation of the present invention is diluted 500 times, and set some control treatment groups to compare:

[0014] Treatment group 1 T1(CK): control without any treatment

[0015] Treatment group 2 T2: control: treated with 2% PGA aqueous solution

[0016] Treatment group three T3: control: treated with 20% PGA aqueous solution

[0017] Treatment group 4 T4: PGA: 50%, urea: 35%, root promoting agent 15% for treatment

[0018] Tre...

Abstract

Relating to the soil salinization control technology, the invention specifically relates to a repairing agent for salinized soil. A biodegradable conditioning and supplying agent for saline-alkali soil is a solution prepared by mixing a mixture composed of 50-70% of high polymeric product PGA from microbial metabolism, 25-35% of urea and 5-15% of root growth promoting agent by weight with water in a proportion of 1:15. Without any harmful effect on soil, the agent of the invention is adaptable to different areas.

Description

technical field [0001] The invention relates to soil salinization prevention technology, in particular, the invention relates to a soil salinization restoration agent. Background technique [0002] Salinized soil is an important land resource. It is widely distributed in more than 100 countries and regions around the world, covering an area of ​​more than 1 billion hectares, accounting for about 30% of the total land area. It is distributed in arid regions on all continents of the world. The proportion of saline soil is significantly higher than the world average level. There are about 17 million hectares of saline soil, and nearly 1 / 3 of the irrigation areas have salinization problems. [0003] Saline soil (saline-alkali soil) refers to the chloride, sulfate, bicarbonate, etc. containing potassium, sodium, calcium, and magnesium in the soil; in addition, there are boron salts in the Qinghai-Tibet Plateau, and nitrates in the Turpan Basin; or the soil contains Although the ...
