Organic fertilizer capable of reducing content of heavy metals in grape and preparation method thereof

Abstract

The invention discloses organic fertilizer capable of reducing content of heavy metals in grape and a preparation method thereof. The organic fertilizer is prepared from the following raw materials and components in parts by mass: 25 to 30 parts of peanut shell, 20 to 25 parts of red chrysanthemum, 22 to 27 parts of egg shell, 15 to 20 parts of herba aponogeton lakhonensis, 26 to 31 parts of herba calthae palustris, 18 to 23 parts of herba leonuri, 20 to 25 parts of green bristle grass, 15 to 20 parts of flos typhae angustifoliae, 8 to 13 parts of benzimidazole-2-methyl carbamate-8-oxine copper, 55 to 60 parts of sheep manure, 20 to 25 parts of humic acid, 40 to 45 parts of acetic acid, 110 parts of water, and 8 to 12 parts of citric acid. The organic fertilizer has the advantages that the danger to fruits by heavy metal is decreased; the soil caking structure is changed, the acid and alkaline balance of the soil is corrected, the decomposing and absorbing of the organic fertilizer are promoted, and the soil bacteria are inhibited; the content of effective silicon in the soil is increased, the absorbing of fruit trees on nutrient matters in the soil is promoted, and the fruit output and quality are obviously improved; the effects of preventing diseases and pests and improving fruiting rate are realized; the swelling function on the fruits is realized, and any swelling agent is not needed; the easiness in falling of grape grains is avoided, the size is uniform, the fruit cracking is avoided, and the rusty pollution is avoided.

Description

technical field [0001] The invention relates to an organic fertilizer for reducing the heavy metal content of grapes and a preparation method thereof, belonging to the field of fruit tree planting. Background technique [0002] Grape, a kind of berry, is one of the oldest and most widely distributed fruits in the world. Humans began to cultivate this kind of fruit tree a long time ago. The berries are mostly round or oval, and the color varies with the variety. Grapes produce almost a quarter of the world's fruit production; they are highly nutritious and can be made into grape juice, raisins and wine for everyone. [0003] For a long time, in order to increase production and income, the long-term excessive use of various chemical fertilizers in the soil, coupled with the pollution of water quality, etc., has led to the decline of soil fertility, the lack of organic matter, and the decrease of soil air permeability, resulting in excessive consumption of nutrients in the soil...
