Tea planting land soil remediation agent and preparation method thereof

Abstract

The invention relates to the technical field of soil remediation, in particular to a tea planting land soil remediation agent and a preparation method thereof. The tea planting land soil remediation agent is a semi-wet and semi-dry powdery mixture and is prepared from substances in parts by weight as follows: 10-30 parts of livestock and poultry excrement, 20-32 parts of a biomass material, 5-12 parts of humic acid, 5-15 parts of river sand, 3.2-9.5 parts of bentonite, 30-45 parts of charcoal, 2-12 parts of diatomite, 2-8 parts of a plant nutrient solution and 2-12 parts of starch. The soil remediation agent is uniformly mixed with a mixed fermentation bacterium solution in the volume ratio being 1:(0.1-0.5) before use, and the mixed fermentation bacterium solution contains nitrogen-fixing bacteria, nitrobacteria and saprophytic bacteria; the soil remediation agent contains rich mixed fermentation bacteria, has significant effects on improving soil hardening and character worsening caused by overuse of nitrogen, phosphorus and potassium, makes soil recover to the original ecological structure and promotes the soil structure to recover to the sufficient fertility state more quickly in combination with multiple nutrients contained in the soil remediation agent.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a soil remediation agent for tea plantation sites and a preparation method thereof. Background technique [0002] Soil is a natural resource that is difficult to regenerate and an important basis for human production activities. At present, the situation of soil pollution in my country is relatively severe, including heavy metal pollution and organic pollution. The safety of agricultural products caused by soil pollution cannot be ignored: soil pollution can reduce crop yield and quality, and also endanger human health through the transmission and enrichment of food chains. In order to remediate polluted soil, countries around the world, especially developed countries, have invested huge manpower, material and financial resources in soil remediation research in recent years, and have made some progress. [0003] Another way of soil pollution has been perplexing soil cu...

Problems solved by technology

The soil remediation agent applies beneficial microorganisms to the soil, optimizes the soil microbial flora, improves soil physical properties, repairs compacted and degraded soil, enhances soil biological activity, regulates crop metabolism; promotes crop growth, and degrades and transforms pollution in the soil However, for perennial bushy crops such as tea trees, there is no guarantee that the restoration agent can reach the base of the plant blocked by the lush picking canopy, or the amount of access is so small that the restoration effect is poor
