Special soil improvement agent for tea crops

Abstract

The invention discloses a special soil improvement agent for tea crops. The special soil improvement agent comprises the following components in percentage by mass: 0.2-0.5% of siliceous petrochemical powder, 13.3-16.6% of amino acid powder, 17.8-26.5% of phosphates, 9.6-13.8% of rice bran, 2.7-5.2% of fish meal, 12.6-19.2% of potassium sulfate, 8.2-10.2% of urea, 2.1-4.6% of peat, 1.9-5.6% of shell powder containing calcium carbonate and 12.6-16.8% of soybean meal. An application of the special soil improvement agent for the tea crops comprises the following steps: (1) uniformly applying the special soil improvement agent for the tea crops on the surface of the soil near tea root groups 45-75 days before harvesting spring tea; (2) completely wetting the surface of the special soil improvement agent for the tea crops by using water; (3) sprinkling and spreading the special diluted soil improvement agent for the tea crops on tea trees one week before harvesting the tea each time; sprinkling from the leaf surface to the root until the whole tea tree is completely wetted. The special soil improvement agent for the tea crops disclosed by the invention can be used for completely recovering the original softness and activity of an agricultural land, can benefit farmers, and can be used for producing high-quality products for consumers to eat.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to a bio-organic fertilizer and a preparation method thereof. Background technique [0002] The biggest problems in agriculture today are: [0003] 1. Extensive use of chemical fertilizers causes too many phosphate compounds in the soil, resulting in soil deterioration—acidification, hardening, and hardening; [0004] 2. Due to soil deterioration - acidification, hardening, compaction, the root system of crops cannot be stretched, and nutrients cannot be fully absorbed, resulting in poor crop yield and quality year by year, and crop products have only appearance, without proper quality and flavor content; [0005] 3. The amount of chemical fertilizers used by farmers increases every year to maintain the original output, and the increased amount of chemical fertilizers accelerates the deterioration of the soil; [0006] 4. Due to the extensive use of chemical fertilizers, there is a large l...
