Fruit tree fertilizer with bran as main component and preparation method of fruit tree fertilizer

Abstract

The invention discloses a fruit tree fertilizer with bran as a main component. The fruit tree fertilizer is prepared from the following raw materials in parts by weight: 200-230 parts of bran, 100-120 parts of fermented cotton seed hulls, 120-140 parts of shiitake residues, 20-24 parts of flour, 20-24 parts of bentonite, 12-15 parts of zeolite powder, 12-15 parts of bamboo charcoal powder, 16-19 parts of potassium chloride, 10-12 parts of urea, 4-6 parts of ferrous sulfate, 3-5 parts of zinc sulfate, 2-3 parts of sodium sulfate, 1-2 parts of calcium lignosulphonate, 6-9 parts of an EM (Effective Microorganisms) bacterium agent, 10-15 parts of a soil conditioner, and an appropriate amount of water. With the bran, the fermented cotton seed hulls, the shiitake residues and the like as main raw materials, the fruit tree fertilizer is an organic fertilizer with rich nutrients and contains rich enzyme systems, proteins, carbohydrates, vitamins, mineral substances and the like, thereby having very high economic and social benefits. The added bamboo charcoal powder contains a large quantity of water-soluble mineral substances such as potassium, sodium, calcium and magnesium and has a powerful adsorbing capability, thereby being capable of adsorbing harmful substances such as heavy metals from soil and consequently playing a soil purifying role.

Description

[0001] technical field [0002] The invention relates to the technical field of fertilizers, in particular to a fruit tree fertilizer mainly composed of bran and a preparation method thereof. Background technique [0003] Fruits have long been loved by consumers for their rich vitamins, minerals, cellulose and fructose. Fruit occupies a large proportion in people's daily diet, and the consumption is very large, with equal emphasis on food and vegetables. In this regard, in order to obtain better economic benefits, the pursuit of high yield, low cost, and high-quality production goals largely depends on the fertilizer applied by the fruit trees. However, the utilization rate of fertilizers is not very high at present, and a large amount of fertilizers are left on the ground, which not only causes a serious decline in soil quality, but also pollutes water bodies, posing a threat to the sustainable development of agriculture and the living environment of human beings.
