Abstract

A kind of microbial fertilizer of efficient general, its particle be by hilum, skin, and skin membrane constitutes, and is to adopt weathered coal (or coal gangue) to be main raw material, cooperates the fermented product of wheat bran, bittern, lime or gypsum, talcum powder, gelatine is formed.The fertilizer grain of making has fixed nitrogen, phosphate solubilization, and through the field experiment of constituent parts such as the Chinese Academy of Agricultural Sciences, to grain, fruit tree, vegetables have good production-increasing function, are a kind of nontoxic, and be harmless, the new-type fertilizer of environmental nonpollution.

Description

Efficient, general microbial fertilizer with three-decker particle

The present invention relates to a kind of efficient general microbial fertilizer with three-decker particle, a kind of is the efficient general microbial fertilizer of main raw material with weathered coal (coal gangue).

At present; what use in a large number on the agricultural is chemical fertilizer; As time goes on the practice of using; people recognize that gradually chemical fertilizer is to contaminate environment; make soil compaction; reduce shortcomings such as crop quality. therefore, seek a kind of nontoxic. harmless. pollution-free. the new-type fertilizer that can protect the environment eubiosis is the major objective of various countries' agricultural development.

The object of the present invention is to provide a kind of novel microorganism fertilizer that three-decker particle particle form has efficient general that has, it is a kind of real nontoxic. harmless. and environmentally safe. for grain. vegetables. what farm crop such as fruit tree can both be increased production is the novel microorganism fertilizer of main raw material with weathered coal (or coal gangue).

The present invention implements like this:

(1) the phosphorus ore thing with nutrition is ground into particulate, with the wheat bran fermented product. bittern (major ingredient is a sodium sulfate. sal epsom) and mixing granulation becomes a core.

(2) weathered coal (or coal gangue) is ground into particulate and another kind of wheat bran fermented product. bittern. lime. gypsum mixes as the particulate skin.

(3) talcum powder. the aqueous solution of gelatine is sprayed at outer field surface as skin membrane, so just has a core. skin. skin membrane specific granule structure.The effect of grain core is the biological phosphorus decomposing that promotes phosphorus ore containing. prevent that the soil metallic cation is to the phosphorus fixation effect; outer field effect has been a fixed nitrogen. as for sodium sulfate in grain core and the skin and sal epsom mainly is to promote photosynthesis of plants and metabolism. as for skin membrane; mainly be destruction for the anti-block of nitrogen-fixing microorganism; and the integrity of protection endothecium structure, create local biological metabolism environment.

Concrete grammar of the present invention is as follows with relevant prescription: (by weight following)

(1) grain core:

Ground phosphate rock: 65-70(crosses 200 mesh sieves, and phosphorus content is with P ₂O ₅Meter 〉=25%)

The wheat bran fermented product: the 28-32.(zymophyte is the vitamins B zymophyte that pharmacy 12 factories in Shanghai produce. the weight ratio of zymophyte and wheat bran is 1: 10. leavening temperature is 28-37 ℃. the time is 9-12 hour).

Bittern: 28-32(includes 10 aqueous sodium persulfate 14-16 weight part .7 water magnesium sulfate 14-16 weight parts)

(2) skin:

Weathered coal (or coal gangue) powder: 200 order .65-70.(degree of weathering＞80% loss on ignition＞35%)

The wheat bran fermented product: the 15-18(zymophyte be Beijing general brewery pyruvate fermentation bacterium of producing with the amount of wheat bran than 1: 10. leavening temperature is 30-37 ℃. the time is 9-12 hour)

Bittern: 0.5-1(10 aqueous sodium persulfate and sal epsom half and half)

Lime (or gypsum): 1.5-2

(3) skin membrane:

(4) grain core: skin: skin membrane=(24-28): (72-76): 2

(5) the grain core diameter is the 1.8-1.9 millimeter. outer layer thickness is the 0.7-0.9 millimeter.

Following preference is described in detail the present invention, but does not limit the scope of the invention.

Example 1: first: the preparation of grain core in a general pulverizer is that 30% phosphorus ore is pulverized with 67 kilograms of phosphorus contents, and then undertaken by general pulverizer levigate, until whole powders by 200 mesh sieves.

In a general fermentor tank, put into 30 kilograms in wheat bran, and 1 kilogram of the Shanghai pharmacy 12 factories vitamins B zymophyte of producing, in 32 ℃ of bottom fermentations 10 hours, move into then in the mixing tank and (include 10 aqueous sodium persulfates with bittern, 7 water magnesium sulfates half and half) 30 kilograms, mix, and 45 ℃ dry 10 minutes down, and pulverize and pass through 100 mesh sieves with general pulverizer.

Above-mentioned ground phosphate rock and wheat bran fermented product are mixed with the bittern powder, and granulation in general tablets press, the diameter of particle is 1.86 millimeters.

(2) outer field preparation:

In general pulverizer, 67 kilograms weathered coal (degree of weathering 85% loss on ignition is 42%) is pulverized earlier, then in general pulverizer grinding to all by 200 mesh sieves.

In a general fermentor tank, put into 16 kilograms in wheat bran, 1.6 kilograms of the pyruvate fermentation bacterium that Beijing general brewery produces, in 35 ℃ of bottom fermentations 10 hours, then under baker in 50 ℃ of oven dry 10 minutes down, in mixing tank with 0.5 kilogram in bittern, 1.5 kilograms of mixing of lime.

(3) granulation: in general tablets press with 25 kilograms of the core materials of grain of (1); carry out a core granulation; add 75 kilograms of outer compounds then; carry out particle and increase granulation; spray into by 2 kilograms of talcum powder 0.3 kilogram in gelatine, the skin membrane aqueous solution of 21 kilograms of compositions of water at last. and in general dryer, dried 10 minutes down in＜65 ℃; just becoming of the present invention efficient, the general thing fertilizer of supporting one's family. the grain diameter that makes is 3.5 millimeters.

The weathered coal of example 2. in skin changes coal gangue into and lime changes into the gypsum, and all the other conditions are identical with example 1, and making fertilizer particle diameter of the present invention is 3.4 millimeters.

Through units concerned (Beijing Forestry University. Peking University. Beijing Normal University. Beijing Agricultural University. Chinese forest-science academy) analysis, the solid N ability of the product grain core of example 1 and example 2 all is=100umol(8 days), outer field solid N ability all is=100umol(8 days).

Of the present invention efficient, general microbial fertilizer, by the Chinese Academy of Agricultural Sciences to flue-cured tobacco. grape. apple. wheat; Beijing Agricultural College is to wheat; The Zhejiang Huzhou City is to late rice; Beijing Luo Ping agricutural industrial ﹠ commercial united corporation has all obtained the effect of high yield and bumper harvest to the field experiment of corn.

Advantage of the present invention: 1. raw material sources are abundant, and are simple for production;

2. all kinds of crops there is effect of increasing production;

3. nontoxic, harmless, environmentally safe.
