A kind of corn field special fertilizer utilizing wormcast to prepare
Technical field
The present invention relates to a kind of method utilizing wormcast to prepare corn field special fertilizer.
Background technology
In low-yield land, corn growth is slow, and blade is easily wilted, and when running into wind, water, drought, there will be the phenomenon such as hypoevolutism, lodging, easily falls ill, and forms threaten greatly corn yield.Occur that in the corn field of the problems referred to above, soil hardens, permeability is deteriorated, soil physico-chemical property worsen, water, fertilizer, vapour, heat inharmonious, soil microbial activities weakens greatly, soil with organic matter content declines gradually, in topsoil, effectively soil amount significantly reduces, soil water-reataining fertilizer-keeping reduced capability, and severe soil plough horizon causes maize root system to take root difficulty, have impact on corn absorbing moisture and nutrient greatly, limit corn with high yield, stable yields.
A lot of area adopts little agricultural machinery and implement to carry out farm work, and topsoil is dark not, causes topsoil to harden, is unfavorable for growing of root system.Therefore a lot of area starts to adopt large farm machinery to plough deeply, and breaks plough sole, adds deep plough level, and adopt deep-ploughing implement, the meticulous soil that makes reaches loose soft good order and condition wholely.Owing to using chemical fertilizer year after year, soil with organic matter content is fewer and feweri, has some areas to adopt straw-returnings, culture fertility, improvement soil, for growing of corn provides a good environment.
Summary of the invention
The present invention is directed to the problems such as hardening appears in corn field soil, physico-chemical property deterioration, invent and a kind ofly can enrich the corn field special fertilizer that soil nutrient can improve again soil property.
This patent is a kind of technology and method utilizing wormcast to prepare corn field special fertilizer, and wherein wormcast 30 parts, maize straw 30 parts, rice straw 30 parts, Lumbrukinase stoste 7 parts, fermenting agent 2 parts, calcium superphosphate 2 parts, 2 parts, brown sugar, 1 part, zinc sulfate and boric acid 1 part are mixed.
The common yellow wormcast that in above-mentioned a kind of corn field special fertilizer utilizing wormcast to prepare, wormcast produces for artificial culture earthworm, containing a large amount of organic matters, macroelement and trace element, having the effect of strong sprout, preventing disease and pest, is a kind of organic fertilizer of green.
In above-mentioned a kind of corn field special fertilizer utilizing wormcast to prepare, rice straw and shredding corn stalk are to 5cm length.
The preparation method of Lumbrukinase stoste in above-mentioned a kind of corn field special fertilizer utilizing wormcast to prepare: get a certain amount of fresh and alive earthworm, be placed in clear water, after 24 hours, taking-up is put into and is extracted bed, and from top to bottom per minute 1000ml inducible enzyme is atomized spray, stimulates earthworm to secrete a large amount of enzymic activity materials to reach, then the speed of 6000 rpms is passed through by centrifugal for enzymic activity material 10 minutes, get supernatant liquor, adopt gel-filtration chromatography to filter, obtain Lumbrukinase stoste.
Above-mentioned a kind of corn field special fertilizer utilizing wormcast to prepare comprises following step:
By wormcast 30 parts, maize straw 30 parts, rice straw 30 parts, fermenting agent 2 parts, calcium superphosphate 2 parts and brown sugar stirring and evenly mixing, starting material water content remains between 65%-70%, stack higher to physical features, ventilate good position, heap height 1.0-1.5m, the wide 1.5-2.5m of heap body, keep heap body internal temperature to be stabilized in 50 DEG C-60 DEG C, when the 4th day, even turning once, and fermentation number of days can become thoroughly decomposed for 7-12 days.Then with Lumbrukinase stoste, zinc sulfate and boric acid stirring and evenly mixing, corn field special fertilizer is.
Feature of the present invention: not only containing a large amount of nitrogen, phosphorus, potassium, organic matter and micro-in above-mentioned corn field special fertilizer, simultaneously containing a large amount of beneficial microorganisms, can activating soil, promote that corn is to the absorption of nutrient, improve soil and push up physicochemical character and structure, chessom, makes water, fertilizer, vapour, heat coordinate mutually, forms the edatope being applicable to corn growth.
Specific embodiments
Embodiment 1
A kind of method utilizing wormcast to prepare corn field special fertilizer of the present invention is, by wormcast 30 parts, maize straw 30 parts, rice straw 30 parts, Lumbrukinase stoste 7 parts, fermenting agent 2 parts, calcium superphosphate 2 parts and brown sugar 2 parts of stirring and evenly mixings, starting material water content remains between 65%-70%, stack higher to physical features, ventilate good position, heap height 1.0-1.5m, the wide 1.5-2.5m of heap body, heap body internal temperature is kept to be stabilized in 50 DEG C-60 DEG C, when the 4th day, even turning once, and fermentation number of days can become thoroughly decomposed for 7-12 days.Then boric acid and zinc sulfate and Lumbrukinase stoste are sprayed uniformly on heap body, stir, airing can pack warehouse-in when water content is 10%, is corn field special fertilizer.
The common yellow wormcast that in above-mentioned a kind of corn field special fertilizer utilizing wormcast to prepare, wormcast produces for artificial culture earthworm, containing a large amount of organic matters, macroelement and trace element, having the effect of strong sprout, preventing disease and pest, is a kind of organic fertilizer of green.
In above-mentioned a kind of corn field special fertilizer utilizing wormcast to prepare, rice straw and shredding corn stalk are to 5cm length.
The preparation method of Lumbrukinase stoste in above-mentioned a kind of corn field special fertilizer utilizing wormcast to prepare:: get a certain amount of fresh and alive earthworm, be placed in clear water, after 24 hours, taking-up is put into and is extracted bed, and from top to bottom per minute 1000ml inducible enzyme is atomized spray, stimulates earthworm to secrete a large amount of enzymic activity materials to reach, then the speed of 6000 rpms is passed through by centrifugal for enzymic activity material 10 minutes, get supernatant liquor, adopt gel-filtration chromatography to filter, obtain Lumbrukinase stoste.
