A biological organic composite fertilizer specially used for vegetables and fruits and a preparing method thereof

Abstract

A biological organic composite fertilizer specially used for vegetables and fruits is disclosed. The fertilizer is characterized in that: the fertilizer comprises raw materials comprising 30-35 parts by weight of saw dust, 1-2 parts by weight of zinc oxide, 8-10 parts by weight of expanded perlite micro powder, 9-11 parts by weight of calcium superphosphate, 20-23 parts by weight of urea, 2-4 parts by weight of polyglutamic acid, 3-5 parts by weight of fulvic acid, 46-48 parts by weight of tea dregs, 56-59 parts by weight of traditional Chinese medicine dregs, 2-3 parts by weight of sodium silicate, 18-21 parts by weight of potassium phosphate, 14-17 parts by weight of potassium oxide, 16-18 parts by weight of polyethylene, 5-7 parts by weight of an EM bacterial agent, 7-9 parts by weight of a soil conditioner and a proper amount of water; and microbial fermentation products of the dregs produced in tea production and the traditional Chinese medicine dregs, etc., are organically combined with mineral compounds and inorganic elements, and a coating process is adopted, and therefore the fertilizer is good in slow release effect, high in fertilizer efficacy, durable in fertilizer efficacy, and convenient in production and using, the fertilizer has a function of resistance to successive cropping obstacle, the fertilizer can obviously increase the crop output when the fertilizer is used, and the fertilizer is specially suitable for vegetables and fruits.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special bio-organic compound fertilizer for vegetables and fruits and a preparation method thereof. Background technique [0002] At present, chemical fertilizers are mostly used as fertilizers for vegetables, fruits and other crops, but chemical fertilizers have the following disadvantages: First, they may weaken the production capacity of vegetables. There are two main consequences of excessive fertilization on vegetables: one is that they are prone to lodging, and once lodging occurs, it will inevitably lead to a reduction in yield; Infestation by diseases and insect pests, and then increasing the amount of pesticides used to eliminate diseases and insect pests, directly threatens the safety of food; the second is to aggravate environmental pollution. When the amount of fertilizer applied excessively exceeds the holding capacity of the soil, it will flow into the surrounding wate...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the fertilizers used for vegetables, fruits and other crops are chemical fertilizers, but chemical fertilizers have the following shortcomings: First, it may weaken the production capacity of vegetables

There are two main consequences of excessive fertilization on vegetables: one is that they are prone to lodging, and once lodging occurs, it will inevitably lead to a reduction in yield; The infestation of diseases and insect pests, and then increasing the amount of pesticides to eliminate diseases and insect pests, directly threatens the safety of food; the second is to aggravate environmental pollution

When the amount of fertilizer applied excessively exceeds the holding capacity of the soil, it will flow into the surrounding water, forming agricultural non-point source pollution, causing eutrophication of the water body, leading to the growth of algae, and then destroying the water environment

The third is to waste a lot of scarce resources
