Abstract

The invention discloses an organic fertilizer and a preparation method thereof. The organic fertilizer is prepared from the following raw materials in parts by weight: 40-50 parts of fresh cow dung, 30-40 parts of rice hull powder, 25-30 parts of wheat straw, 1-3 parts of EM fungicide, 7-12 parts of zeolite powder, 8-11 parts of tea dregs, 10-13 parts of a soil improving agent, 2-3 parts of zinc sulfate, 2-4 parts of ferric sulfate, 1-2 parts of copper sulfate and 1-2 parts of manganese sulfate. The organic fertilizer disclosed by the invention utilizes nutrient in agriculture waste materials, not only is environment pollution avoided, but also insects in soil can be killed by vegetable alkaloid and aromatic oil in tea dregs; the EM fungicide can generate microorganisms which are beneficial for biological growth, and fertility release and crop growth are improved. Because of the improving agent, the physical and chemical properties of soil and the soil nutrient can be effectively improved, absorption of nutrition and moisture of plant is prompted, and the positive influence on soil microorganisms is made.

Description

A kind of organic fertilizer and preparation method thereof

Technical field

The present invention relates generally to a kind of technical field of fertilizers, particularly a kind of organic fertilizer and preparation method thereof.

Background technology

China's agricultural planting amount is large, life-time service chemical fertilizer, and chemical fertilizer plays an important role in China's agriculture production as the factor of determination of farming volume increase.At present, China has become maximum in the world chemical fertilizers production Guo Yu country of consumption, but life-time service can make soil aggregate be destroyed, easily cause soil compaction, soil property hardening, adopt soil improvement agent can make to prevent that soil from weathering, reducing soil water evaporation or excessively transpiration, save irrigation water and promoting the effects such as plant health growth.

Summary of the invention

The present invention aims to provide a kind of organic fertilizer and preparation method thereof.

The present invention is achieved by the following technical solutions:

Organic fertilizer is made by the raw material of following weight part: fresh cow dung 40-50, powdered rice hulls 30-40, wheat straw 25-30, EM microbial inoculum 1-3, zeolite powder 7-12, tea grounds 8-11, soil improver 10-13, zinc sulfate 2-3, ferric sulfate 2-4, copper sulfate 1-2, manganous sulfate 1-2.

Soil improver is made by the raw material of following weight part: diatomite 100-120, nano-carbon powder 1-2, oil foot 4-5, Starso 4-5, Silane coupling agent KH550 1-2, Sodium Selenite 3-4, chitosan 2-3, Oil of Eucalyptus 1-2, alcohol ester 12 1-2, nanometer jade powder 2-3, Root of Chinese Azalea 4-5, garlic 3-4, water are appropriate; Preparation method is broken into powder by Root of Chinese Azalea, garlic powder, add suitable quantity of water and grind to form slurry together with diatomite, reheat slurry to 80-90 ℃, add nano-carbon powder, nanometer jade powder to continue to grind 30-45 minute, then add Starso, chitosan to stir and within 10-15 minute, become pasty state, add again other remaining component, after stirring, granulation, dry and get final product.

The preparation method of described fertilizer is:

(1) after fresh cow dung, powdered rice hulls, wheat straw, EM microbial inoculum are stirred, normal temperature fermentation 4-6 days; (2) continue fermentation 10-13 days after adding zeolite powder, tea grounds, soil improver to stir;

(3) after adding and stirring after zinc sulfate, ferric sulfate, copper sulfate, manganous sulfate, fermentation 3-4 days, obtains fertilizer after Drying and cooling.

Beneficial effect of the present invention:

Organic fertilizer of the present invention has utilized the nutrient in agricultural waste, has not only avoided environmental pollution, also can utilize vegeto-alkali contained in tea grounds and perfume oil to kill the insect of Tian Tuzhong; EM original solution biological bacteria can produce the microorganism that is of value to biological growth, promotes fertility to discharge and plant growth.Improving agent can effectively improve soil physico-chemical property and soil nutrient status promotes plant to produce active influence for the absorption of nutrient and moisture and to soil microorganisms.

Embodiment

Organic fertilizer is made by the raw material of following weight part (kg): fresh cow dung 40, powdered rice hulls 35, wheat straw 27, EM microbial inoculum 2, zeolite powder 11, tea grounds 9, soil improver 10, zinc sulfate 2, ferric sulfate 3, copper sulfate 2, manganous sulfate 2.

Soil improver is made by the raw material of following weight part (kg): diatomite 120, nano-carbon powder 1, oil foot 4.5, Starso 4.1, Silane coupling agent KH550 2, Sodium Selenite 3.5, chitosan 2.4, Oil of Eucalyptus 1.6, alcohol ester 12, nanometer jade powder 2.6, Root of Chinese Azalea 4.6, garlic 3, water are appropriate; Preparation method is broken into powder by Root of Chinese Azalea, garlic powder, add suitable quantity of water and grind to form slurry together with diatomite, reheat slurry to 86 ℃, add nano-carbon powder, nanometer jade powder to continue to grind 36 minutes, then add Starso, chitosan to stir and within 12 minutes, become pasty state, add again other remaining component, after stirring, granulation, dry and get final product.
