Abstract

A bioactive granular fertilizer is composed of the inner core containing powdered phosphorus ore, fermented wheat bran and Na-Mg brittern, the internal layer containing powdered weathered coal, fermented wheat bran, Na-Mg bittern and gypsum, and the external layer containing talc powder and bone glue. Its advantages include high and durable fertility, and improving soil.

Description

Biologically active granular fertilizer and method for making thereof

The present invention relates to a kind of mixture fertilizer, be specifically related to a kind of multiple inorganics blended particle fertilizer that contains microorganism.

Produce from chemical fertilizer, fertilizer input in the agriculture production is based on chemical fertilizer, organic fertilizer only accounts for a little, though chemical fertilizer has the fertility height, and the advantage that fertilizer efficiency is fast, but because the chemical fertilizer composition is single relatively, life-time service causes soil compaction easily, and soil property worsens, even has influence on the quality of agricultural-food, and make chemical fertilizer and produce serious industrial pollution, so be the new trend of agriculture production with organic fertilizer and other use of the alternative chemical fertilizer of fertilizer non-chemically.

Application number is that 98112036 Chinese patent application discloses a kind of bioactive compound fertilizer and manufacture method thereof; its composite fertilizer is that the microbial-bacterial fertilizer particle of 10-20 and the fertile particle of mixing of 80-90 mix by weight percent; it mixes fertile weight percent and constitutes inorganic fertilizer 35-80; fertilizer 5-50; trace element 5-1 0; medium carrier 5-19, binding agent 0-1.This composite fertilizer is characteristics with the compound of various fertilizer, and is equipped with a spot of microbial-bacterial fertilizer, though the nutrition of comparison isostatic can be provided, but still based on conventional fertilizer, the effect of microbial-bacterial fertilizer is obvious inadequately, and its relative cost does not reduce.

The object of the present invention is to provide a kind of fertilizer that do not contain, highly active bio-feritlizer cheaply.

Another object of the present invention provides the manufacture method of this fertilizer.

Goal of the invention of the present invention is to adopt following technical scheme to realize:

Biologically active granular fertilizer material of the present invention has following laminate structure and every layer of weight percentage proportioning:

A, inner core: ground phosphate rock 50-60, wheat bran fermented product 20-30, sodium magnesium salts halogen 20-30;

B, internal layer: weathering coal dust 65-70, wheat bran fermented product 25-35, sodium magnesium salts halogen 0.5-1, gypsum 1.5-2;

C, theca externa: talcum powder 80-90, gelatine 10-20.

In the above formation, the effect of inner core is the biological phosphorus decomposing that promotes phosphorus ore containing, prevent the soil metallic cation to the phosphorus fixation effect, the effect of internal layer has been the fixed nitrogen effect, and wherein the sal epsom of the sodium sulfate in inner core and the internal layer mainly is to promote photosynthesis of plants and metabolism.Theca externa is the destruction because of the anti-block of nitrogen microorganism, and can protect the integrity of inner structure, creates local biological metabolism environment.

This fertilizer does not contain chemical inorganics, produces required nitrogen, phosphorus, the potassium nutrition composition of crop by the active bio bacterium, and fertilizer efficiency is long, and the fertility height can effectively improve quality of agricultural product; No industrial pollution, prevented a large amount of use chemical fertilizer and run off caused to phreatic pollution, the joint medicine energy.

Biologically active granular fertilizer material of the present invention adopts following manufacture method:

1. inner core: a, phosphorus ore be milled to powder cross 200 mesh sieves;

B, with wheat bran and vitamins B zymophyte by anharmonic ratio 10: 1 at 28-37 ℃ of bottom fermentation 9-12 hour;

The mixture drying of c, wheat bran fermented product and bittern, temperature are 45 ℃;

D, granulation, its diameter are the 1.8-1.9 millimeter.

2. internal layer: a, weathered coal be ground into powder cross 200 mesh sieves;

B, with wheat bran and pyruvate fermentation bacterium be by weight 10: 1 at 30-37 ℃ of bottom fermentation 9-12 hour;

The mixture of c, wheat bran fermented product and halogen, gypsum is dry down at 50 ℃;

D, wrap a core granulation, wrap thickness 0.7-0.9 millimeter.

3. adventitia: gelatine, the talcous aqueous solution are sprayed at particle surface.

Embodiment:

Get and contain P ₂O ₅30% rock phosphate powder comminution powder is crossed 70 kilograms in the powder of 200 mesh sieves.Get 25 kilograms in wheat bran, add 1 kilogram of the plain B zymophyte of commercially available little life, in 32 ℃ of bottom fermentations 10 hours, move into then in the mixing tank and mix with bittern, wherein bittern for contain 10 aqueous sodium persulfates and 7 water magnesium sulfates each 50%, the weight that adds bittern is 30 kilograms, mix the back and in 45 ℃ dry 10 minutes down, pulverize also by 100 mesh sieves the back.After this with above-mentioned ground phosphate rock and wheat bran fermented product and bittern powder thorough mixing, granulation is 1.86 millimeters of diameters, the corning core.

Get 67 kilograms weathered coal (degree of weathering 85% is burnt vector 42%) and pulverize the back abrasive dust earlier by 200 mesh sieves.Get 16 kilograms in wheat bran, 1.6 kilograms of pyruvate fermentation bacterium in 35 ℃ of bottom fermentations 10 hours, 50 ℃ of oven dry 10 minutes, are mixed and made into interior layered material for 1.5 kilograms with 0.5 kilogram in bittern, gypsum then again.After get 25 kilograms of the core materials of grain of granulation, layered material is 75 kilograms in adding, wrap the increase particle diameter, spray into by 2 kilograms of talcum powder, 0.3 kilogram in gelatine, 21 kilograms of skin membrane aqueous solution of forming of water after wrapping fully, spraying evenly, the back in 65 ℃ down roars of laughter did 10 minutes, make to such an extent that diameter is 3.5 millimeters a biologically active granular fertilizer material.
