Description
Technical field
The present invention relates to a kind of vegetable fertilizer preparation method, and in particular to the method for preparing fertilizer for vegetable cultivation.
Background technology
Above China's vegetable fertilizer with fertilizer mainly based on nitrogen, phosphorus, potassium, but with the development of the social economy, vegetables
Consumption figure increasingly increases, and vegetables turn into one of food essential in people's diet gradually, due to planting vegetable in greenhouse
Industry can provide fresh vegetables for people everyday at all seasons, and be developed rapidly, and according to statistics, current vegetable supply is total
The 15% of amount comes from planting vegetable in greenhouse industry, and as field crop, current planting vegetable in greenhouse applies fertilizer, quick-acting chemistry
Fertilizer is excessively applied, especially nitrogenous fertilizer, causes to occur that nutrient is single, utilization rate is low, lack organic component and middle trace element, raw
The fruit-vegetable quality of output declines, taste deterioration the problems such as, long-term use can also make soil hardening, destroy soil texture, be unfavorable for
Effective sustainable development using with vegetable cultivation industry of land resource, because people are formd partially to fertilize without weight for a long time
Depending on the present situation of organic fertilizer application, soil productivity and the quality of vegetables are not only reduced, also there is very huge to ecological environment
Destruction.
The content of the invention
The technical problems to be solved by the invention are the fertilizer that existing vegetable cultivation is applied, and nutrient is single, utilization rate is low, makes
Fruit-vegetable quality declines, taste deterioration, and destroys soil texture, and considerable damage is caused to ecological environment, it is therefore intended that provide use
In the method for preparing fertilizer of vegetable cultivation, the growth of vegetables can be accelerated, and the effect of each element can be given full play to, while in fertilizer
The trace element and plant hormone needed for plant growth are also added in material, the yield and quality of booth vegetable, Ke Yiman is improved
The need for sufficient crops branch bar, cauline leaf, fruit and seed growth, and turn waste into wealth, environmentally friendly, fertility slowly discharges,
With the effect such as water conservation, fertilizer conservation function, the yield and quality that improve vegetables.
The present invention is achieved through the following technical solutions：
For the method for preparing fertilizer of vegetable cultivation, comprise the following steps：1) microbial bacterial agent is entered respectively using brown sugar
Row expands culture, and nutrient solution is made, and adds wheat bran in nutrient solution, obtains biological wheat bran；2) by cotton seed hulls, cocoanut shell, sugarcane
Slag, straw, mushroom slag, cinder mixing is broken, then adds pig manure, fresh cow dung and suitable quantity of water, and stirring mixing makes the slurry be in
Pasty state；3) by step 2) in slurry be divided into many parts, every two parts between lay and fermented under biological wheat bran, sealing, normal temperature, obtain
Organic fertilizer；4) organic fertilizer fermented is dried, is divided into two parts after crushing, a copy of it is changed with nitrogenous fertilizer and potash fertilizer and soil
Property agent the fertile particle of compound A is made by comminutor, compound B fertilizer is made by comminutor with phosphate fertilizer and soil modifier in another
Particle, regard the compound B fertilizer as base manure；Wherein, the parts by weight of above-mentioned raw materials are as follows：35-45 parts of cotton seed hulls, cocoanut shell 25-
35 parts, 32-40 parts of bagasse, 30-36 parts of straw, 8-12 parts of mushroom slag, 90-100 parts of pig manure, fresh cow dung 35-45 parts, cinder
8-12 parts, 4.2-5 parts of wheat bran, 0.8-1.2 parts of brown sugar, 10-12 parts of soil conditioner, 0.1-0.3 parts of microbial bacterial agent, nitrogenous fertilizer
60-70 parts, 55-65 parts of phosphate fertilizer, 65-75 parts of potash fertilizer and appropriate water.
The environmental friend fertilizer of the present invention, can accelerate the growth of vegetables, and can give full play to the effect of each element, simultaneously
The trace element and plant hormone needed for plant growth are also added in fertilizer, the yield and quality of booth vegetable is improved, can
The need for meeting crops branch bar, cauline leaf, fruit and seed growth, and turn waste into wealth, environmentally friendly, fertility is slowly released
Put, with the effect such as water conservation, fertilizer conservation function, the yield and quality that improve vegetables.By organic fertilizer with without the phase between inorganic fertilizer
Mutually combine, the speed of growth of vegetables had both been ensure that, while its nutritional quality is improved, while by adding soil conditioner, energy
It is enough that good improvement is carried out to soil, it is to avoid the influence that inorganic fertilizer is caused to soil.
The microbial bacterial agent is EM bacteria agent.
The soil conditioner is made up of the raw material of following parts by weight：Bamboo charcoal 10-20, nano-carbon powder 1-2, sodium metasilicate 4-
5th, methyl methacrylate 17-19, yeast selenium 3-4, copper sulphate 2-3, zinc gluconate 2-3, magnesium chloride 1-2, ammonium molybdate 2-3,

The nitrogenous fertilizer is ammonium nitrate, and the potash fertilizer is potassium chloride, and the phosphate fertilizer is calcium superphosphate.
The straw includes at least one of cowpea stalk, soybean stalk, Kidney bean stalk.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention is used for the method for preparing fertilizer of vegetable cultivation, can accelerate the growth of vegetables, and can give full play to each
The effect of element, while trace element and plant hormone needed for plant growth is also added in fertilizer, improve booth vegetable
Yield and quality, the need for crops branch bar, cauline leaf, fruit and seed growth can be met, and turn waste into wealth, to environment
Close friend, fertility slowly discharges, with the effect such as water conservation, fertilizer conservation function, the yield and quality that improve vegetables；
2nd, the present invention is used for the method for preparing fertilizer of vegetable cultivation, by organic fertilizer and without the mutual knot between inorganic fertilizer
Close, both ensure that the speed of growth of vegetables, while its nutritional quality is improved, while by adding soil conditioner, can be right
Soil carries out good improvement, it is to avoid the influence that inorganic fertilizer is caused to soil；
