Special slow release fertilizer for grapes and preparation method thereof

Abstract

The invention discloses special slow release fertilizer for grapes. The fertilizer is prepared from, by weight, 100-120 parts of brewery wastewater, 50-80 parts of sugar refinery wastewater, 20-30 parts of vinasse, 80-90 parts of corncob powder, 50-60 parts of peanut hull powder, 30-40 parts of wheat bran, 60-90 parts of residues of oil manufacture, 50-60 parts of smooth vetches, 70-80 parts of sweet clovers, 60-80 parts of azoila imbricata, 5-8 parts of zeolite powder, 10-12 parts of activated carbon, 30-50 parts of horse manure, 20-40 parts of goat manure, 35-45 parts of chicken manure, 20-30 parts of silkworm excrement, 1.2-2 parts of superphosphate, 0.08-0.1 part of borax, 3-5 parts of complex enzyme preparations, 8-12 parts of complex fermentation microbial agent, 5-10 parts of nanocarbon, 30-40 parts of residues from a biogas digester, 20-30 parts of humate, 15-35 parts of roots of soybeans, 20-25 parts of dregs of a decoction, 16-25 parts of straw powder and the like. The invention further discloses a preparation method of the special slow release fertilizer for grapes.

Description

technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a special slow-release fertilizer for grapes and a preparation method thereof. Background technique [0002] Grape is a fresh fruit with delicious taste, easy eating and high nutritional value. It can also be processed into grape juice, raisins and wine with high nutritional value. Grapes need to absorb more nutrients in a growth cycle. Not only do ordinary fertilizers provide more nitrogen, phosphorus, and potassium. According to the theory of wooden barrels, if they lack other nutrients, they will not be able to grow normally, and the plants will be thin and small. Qi, pollination rate is low, seriously affecting yield.

AI Technical Summary

Problems solved by technology

Grapes need to absorb more nutrients in a growth cycle. Not only do ordinary fertilizers provide more nitrogen, phosphorus, and potassium. According to the theory of wooden barrels, if they lack other nutrients, they will not be able to grow normally, and the plants will be thin and small. Qi, low pollination rate, seriously affecting yield

[0003] At present, in the process of grape cultivation, on the one hand, chemical fertilizers are excessively used, and on the other hand, the nutrients used in chemical fertilizers are not comprehensive, which leads to insufficient accumulation of dry matter and breaks the balance point of grape growth. Although the grape yield is high, the carbon and nitrogen metabolism is not coordinated. Difficulty in grape fruiting and coloring, which affects the absorption of nutrients by grapes

There are also organic fertilizers. Although organic fertilizers have long fertilizer effects, their nutrient content is low and cannot fully meet the needs of high yields.

At present, the method to solve these problems in fertilization is first to increase the amount of organic fertilizer, and second is to use a small amount of chemical fertilizer for multiple times. With the continuous expansion of grape planting, organic fertilizer can no longer meet the needs, and repeated application of chemical fertilizer increases labor. cost and effort
