Tea acidified soil remediation bio-organic fertilizer and preparation method thereof

Abstract

The invention belongs to the technical field of soil improvement, and discloses a tea acidified soil remediation bio-organic fertilizer and a preparation method thereof. The tea acidified soil remediation bio-organic fertilizer is prepared from the following components in parts by mass: 20 to 25 parts of biochar, 10 to 15 parts of plant ash, 10 to 15 parts of river sludge, 15 to 20 parts of earthworm powder, 8 to 10 parts of animal waste, 5 to 10 parts of calcium magnesium phosphate fertilizer, 5 to 8 parts of silkworm excrement, 5 to 8 parts of zinc oxide, 5 to 8 parts of montmorillonite, 1 to 3 parts of clay mineral, 1 to 3 parts of rice husk silicon alkali and 1 to 3 parts of bacillus amyloliquefaciens. The organic fertilizer disclosed by the invention can effectively improve the pH of soil and improve the yield and quality of tea leaves; meanwhile, cost is low, raw materials are easy to obtain, the manufacturing method is simple and convenient, and the fertilizer contains rich medium-trace elements and has a soil disinfection function. The soil conditioner can improve the physical and chemical properties of soil, mainly can adjust the pH value of the soil, prevent soil hardening, improve the granular structure of the soil, loosen the soil and increase air and moisture.

Description

Technical field[0001]The invention belongs to the soil improvement technology, in particular, to a tea-free soil repair biological organic fertilizer and preparation method.Background technique[0002]Current: The tea tree is a typical rope, and its suitable pH is 4.5 to 5.5. After the tea tree planting, the soil will gradually acidify; acid rain, excessive administration of fertilizers, especially urea and ammonium nitrogen fertilizers, especially urea and ammonium nitrogen fertilizer, especially urea and ammonium nitrogen fertilizers. Studies have shown that tea garden soil continuously acidified, according to the research of Tea Institute of Agricultural Sciences, 1990-1991, Jiang, Zhejiang, and Anhui Province, the pH of the three provinces, the pH of the soil of 4.5 or more, pH <4.0 is only 13.7%, The results of the 1998 measurement rose to 43.9%, and recent studies have shown that nearly half of the tea garden soil pH is less than <4.0. From a national, tea garden soil also...
