A boron mud stockyard spraying repair method

Abstract

The invention provides a boron mud storage yard spray repair method, comprising the following steps: (1) slope cleaning; (2) spraying citric acid; (3) manual plowing; (4) spraying humic acid; (5) ) spray sodium polyacrylate; (6) cover straw curtain; (7) lay grid; (8) spray substrate; (9) cover straw curtain, sprinkle water for maintenance. The invention uses citric acid and humic acid, combined with manual plowing, to reconcile the alkalinity of the surface layer of boron mud stockpile, improve the physical and chemical properties of boron mud, and become the soil that can be used for plant growth in the later stage, and use sodium polyacrylate to make the newly plowed The boron mud is agglomerated and solidified to form a stable slope. At the same time, it is used in combination with straw curtains to prevent the alkaline substances at the bottom of the boron mud stockyard from moving up to the surface through capillary action and causing anti-alkali phenomenon; Grow provides a growing environment. The matrix of the invention has good aggregate structure, good water and fertilizer retention, and sufficient matrix nutrients.

Description

technical field [0001] The invention relates to the technical field of boron mud stockyard restoration, in particular to a boron mud stockyard spray repair method. Background technique [0002] At present, the total amount of boron mud accumulation in Liaoning Province is more than 20 million tons, resulting in a large number of exposed boron mud stockpiles. Since there is no grass on the surface of the boron mud stockpile, and the boron mud particles are relatively fine, after losing moisture, they will often scatter with the wind, causing pollution to the atmospheric environment and becoming a public nuisance to the extent that it must be solved. However, due to the poor surface habitat of the boron mud stockyard, there is no nutrient required for normal growth of plants, and the pH value is above 9, it is difficult to directly plant plants on the surface, and the cost of planting plants with thick soil on the surface is so high that at present There are many boron mud st...

Problems solved by technology

However, due to the poor surface habitat of the boron mud stockyard, there is no nutrient required for normal growth of plants, and the pH value is above 9, it is difficult to directly plant plants on the surface, and the cost of planting plants with thick soil on the surface is so huge that at present Many boron mud stockpiles in Liaoning Province are still stored in the open

[0003] At present, the slope greening construction technology mainly focuses on the soil spraying technology, the thick layer substrate technology, the vegetation mixing soil technology, the spraying and mixing planting technology, etc., but none of them can fundamentally solve the salinity and alkalinity of the boron mud yard and the stability of the slope. question
