Acidic biological soil conditioner for American blueberry and preparation method thereof

Abstract

The invention discloses an acidic biological soil conditioner for American blueberry and a preparation method thereof. The soil conditioner is composed of the following raw materials by weight: 30-50 parts of peanut meal, 20-30 parts of mushroom residue, 15-25 parts of paulownia sawdust, 8-12 parts of silkworm excrement, 10-15 parts of turf, 5-10 parts of iron-ore slag, 16-22 parts of diatomite, 10-15 parts of fly ash, 3-4 parts of nidus vespae, 2-3 parts of asarum, 1-2 parts of ginger peel, 2-3 parts of Terminalia catappa leaves, 1-2 parts of angled bittersweet, 1-3 parts of radix euphorbiae lantu and 2-3 parts of stemona. The conditioner developed through biological fermentation technology can improve the pH value of soil and adjust the pH value to an effective range, does not pollute the soil or water, promotes healthy growth of blueberries, also can increase the content of organic matters and sterilization components in the soil, purify growth environment of blueberries, enhance disease resistance of blueberries and realize vigorous growth of the blueberries. The soil conditioner provided by the invention has obvious effects of increasing yield of blueberry, improving quality of blueberry, reducing insect diseases and improving the soil.

Description

technical field [0001] The invention relates to a soil improver and a preparation method thereof, in particular to an American blueberry soil acidic biological improver and a preparation method thereof. Background technique [0002] At present, the blueberry planting area is getting bigger and bigger, but because the blueberry has higher requirements on the soil pH value, if the pH value is too high, it is easy to cause blueberry iron deficiency and chlorosis, the yield is reduced, and even the plants die, 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. ...
