Organic fertilizer capable of improving grape soil and preparation method of organic fertilizer

Abstract

The invention discloses organic fertilizer capable of improving grape soil and a preparation method of the organic fertilizer. The organic fertilizer comprises, by mass, 22-27 parts of melon seed shell, 18-23 parts of gingko, 25-30 parts of egg shell, 19-24 parts of Houttuynia cordata, 22-28 parts of ciliate desert-grass, 15-20 parts of Trifolium repens, 10-15 parts of Convallariae majalis, 18-22 parts of Hypoestes phyllostachya, 19-22 parts of cyazofamid, 50-60 parts of pig manure, 25-30 parts of humic acid, 10-15 parts of ferrous gluconate, 40-45 parts of acetic acid, 110 parts of water and 8-12 parts of sodium bisulfate. The organic fertilizer has the advantages that harm of heavy metals to fruits is reduced and eliminated; soil hardening can be changed, soil acid-base equilibrium is improved, organic fertilizer decomposition and absorption are promoted, and soil germs are inhibited; effective silicon content in soil can be increased, fruit trees' absorption of nutritional substances in soil can be promoted, and fruit yield and quality are evidently increased; diseases and pests can be prevented, and fruit setting rate can be increased; fruit expansion can be achieved, and the use of fruit-expanders is not needed; grape fruits are less prone to falling off, even in size, free of cracking and free of rusty pollution.

Description

technical field [0001] The invention relates to an organic fertilizer for improving grape soil 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. As a result, free n...
