Embodiment 3

Efficient biologic-organic fertilizer of the present invention is to be processed by weight by following material: 20 parts of 70 parts of chicken manures, 20 parts on rice husk, 20 parts of straw powder and compound microbial culture starters;

Its preparation method is with embodiment 1.

Preparing method of the present invention takes the continuously feeding and the mode of discharging continuously to accomplish fermenting process, the flute length 40 ~ 60m that generally ferments, wide 2m, high 1.5 ~ 2.0m, and the fermenter permutation and combination is in semi-enclosed fermentation canopy.The ight soil that produce every day gets in the fermenter and carries out harmless treatment, has every day the material of fermentation ends to go out groove, weekly 7 ~ 10 days phases, avoids feces of livestock and poultry to pile up arbitrarily and causes environmental pollution.

The present invention stirs feces of livestock and poultry and certain proportion stalk, microbial fermentation microbial inoculum by the mixed of regulation, heap is gone in the fermenter, breeds temperature rapidly through mikrobe and raises, and during the fermentation, regularly turns over throwing according to the temperature stack turner.Treat temperature rise to 60 ℃ with turnover throwing machine with the material turning, carry out oxygenation and dehydration.Raw materials such as fresh feces of livestock and poultry and stalk get into from fermentation canopy one side, constantly stir through turnover throwing machine and move to fermentation canopy opposite side, and need about 7 ~ 10 days summer, and need about 10 ~ 15 days winter, i.e. fermentation ends; Mikrobe breeds rapidly in the feces of livestock and poultry fermenting process, can decompose the organic substance in the ight soil strongly, and under the high temperature microbe effect, organic oxygenolysis produces 60 ~ 70 ℃ high temperature kill pathogens, worm's ovum; Biologically dehydrating; The all in small, broken bits and distortion of material by fermentation, nearly all organism, volume reduces, and becomes thick compost.

Moisture is an important parameter of composting process.The microbial life action need constantly absorbs moisture to keep normal metabolic from surrounding environment; And mikrobe can only absorb solvability nutriment; Composting material after suction is softening is prone to be decomposed, so suitable water cut is the prerequisite that keeps mikrobe optimum activity and compost fermentation to carry out smoothly.The water cut that compost suits is then with 45% ~ 65%.

The compost initial stage mainly is the decomposition active of mikrobe, needs the good aeration condition.If poor aeration, aerobic bacteria is suppressed, and compost maturity speed is slow; The Sheng of ventilating on the contrary, not only the nutrient loss of moisture is too much in the heap, and causes organic strong decomposition, and is also unfavorable to the accumulation of soil ulmin.Oxygen in the general heap body remains on 8% ~ 18%.

The high temperature bacterium is higher than mesophilic bacteria to organic degradation efficiency; At the compost initial stage, heap temperature is general and envrionment temperature is approaching, through the effect of mesophilic bacteria 1 ~ 2d; Compost is rapidly heated; Compost temperature reaches 50 ~ 65 ℃, generally keeps 5 ~ 6d pliotherm period to reach innoxious index with kill pathogenic bacteria, worm's ovum and grass-seed, and plays dehydration.Final temp reduces the formation that is beneficial to nutrient conversion and soil ulmin.

During the fermentation, have a large amount of ammonia-state nitrogens to generate, pH value is raise, the fermentation whole process all is in alkaline environment, the high increase of pH value nitrogen loss.Can add stalk, stalk can produce lot of organic acids and regulate PH reduction potential of hydrogen in decomposition course.
