Abstract

The invention discloses a soil acidification remediation agent and an application thereof. The remediation agent comprises raw materials, according to a mass ratio, 40-80% of calcium cyanamide, 5-30% of humic acid, 5-20% of a calcium-magnesium-phosphate fertilizer, 5-20% of dolomite powder, 1-10% of silica and 1-8% of a boron fertilizer. The soil remediation agent is good in acid adjustment effect and simple to use, causes no pollution to the environment, and provides a safe, eco-friendly and efficient product for improvement of soil quality. The remediation agent is low in cost and simple in formula, can effectively raise the pH value of the soil by more than 1.0, and can be effectively applied for soil acidification conditioning, soil disinfection and successive cropping obstacle management for greenhouse vegetables.

Description

(1) Technical field [0001] The invention relates to soil acidification treatment, in particular to a soil acidification restoration agent and its preparation and application. (2) Background technology [0002] Due to the high multiple cropping index, long-term excessive application of chemical fertilizers, and acid rain, the pH value of almost all soil types in southern my country has dropped by 0.13 to 0.80, which is significantly lower than the pH value of the soil census in the 1980s. Soil acidity leads to a decline in soil quality, and degradation has become a major global problem. The intensive production of facility vegetables is relatively high, the greenhouse environment is relatively closed, high fertilizer and water input, high multiple cropping index, and continuous planting of single crops lead to more and more serious acidification of greenhouse soil. According to the survey of cultivated land fertility in recent years, the greenhouse area with soil pH value &l...
