Belgium blackberry soil acidity biological improver and preparation method thereof

Abstract

The invention discloses a Belgium blackberry soil acidity biological improver and a preparation method thereof. The Belgium blackberry soil acidity biological improver is prepared by using the following raw materials, by weight, 30-40 parts of cassava residue, 20-30 parts of plant straw, 15-20 parts of a tea seed cake, 10-15 parts of vegetable leftover, 5-10 parts of soybean curb residue, 20-30 parts of modified zeolite, 5-8 parts of rice husk charcoal, 12-16 parts of sodium silicate, 14-18 parts of polyacrylamide, 5-10 parts of carboxymethylcellulose sodium, 15-25 parts of urea, 10-15 parts of calcium superphosphate, 10-15 parts of boric acid and 8-12 parts of a pyroligneous liquor. The soil improver can adjust the pH value of soil, increases organic matters in the soil, promote the microbial activities of the soil and enhance the fertilizer water penetration of the soil, has the soil improvement, water retention and drought resistance effects, has a strong bactericidal activity, and can sterilize and disinfect the soil, inhibit the growth and reproduction of harmful microbes, reduce the occurrence of soil-borne diseases and insect pests, enhance the disease resistance capability of crops, improve the blackberry output and improve the quality.

Description

technical field [0001] The invention relates to a soil improver and a preparation method thereof, in particular to a Belgian blackberry soil acidic biological improver and a preparation method thereof. Background technique [0002] At present, the planting area of ​​blackberry is getting bigger and bigger, but because blackberry has higher requirements on the soil pH value, if the pH value is too high, it is easy to cause iron deficiency and chlorosis of blackberry, lower yield, and even plant death, so the soil must be improved. Sulfur powder is used in soil improvement, but sulfur powder has pollution and safety problems in soil improvement. Improper use of sulfur powder to adjust acid affects the soil and water environment, and leads to increased toxicity of heavy metals, which increases the content of heavy metals in crops. The human body is harmful, and the sulfur powder irritates people's eyes at 6-8 parts per million, making the eyes red, swollen and painful. Conten...
