Operation principle of the present invention:
The preparation of coffee grounds seedling culture matrix nutrition alms bowl of the present invention adopts the segmented alternating temperature to become the moisture content fermentation method, the fermentation condition of strict control material, have the bacterium of becoming thoroughly decomposed of different degradation functions in different yeast phase inoculations, realized orientation, segmentation and the sustainable degraded of coffee grounds Main chemical component.
In the early stage of material fermentation, i.e. make the temperature of material maintain 20 ~ 30 ℃ in the 1st ~ 2 day of fermentation beginning, lower temperature is conducive to improve Aspergillus, Penicillium notatum to alkaloidal degrading activity in the coffee grounds.Carbohydrate in the raw material components preferably adds in this stage, because its palliating degradation degree of material earlier fermentation is limited, the carbohydrate of being supplied with by material self decomposition is difficult to satisfy the needs of growth of microorganism, replenish an amount of sugar and can promote effectively that its expansion is numerous, realize alkaloidal abundant degraded within a short period of time.
In the mid-term of material fermentation, make the temperature of material maintain 30 ~ 40 ℃ in the 3rd ~ 5 day of i.e. fermentation beginning, at this moment, because the propelling of fermentation process, the heat that produces in the stockpile is conducive to material water ratio to be reduced, and the growth that the moisture content of reduction is intended bracket fungus, partially swollen plan bolt bacterium for the winter is very favourable.The metabolite of the two can be realized degradation selectivity to the poly-aldehydes matter in the coffee grounds and high glycan.Optionally removal is coated on high glycan surface and is filled in the intermolecular poly-aldehydes matter of high glycan, namely remove " diaphragm " and " matrix " between raw fiber on raw fiber surface, and the raw fiber that high glycan is formed only produces limited degraded.
The exposure on raw fiber surface and the matrix of filling to each other are eliminated, for receiving of moisture provides sufficient space, the polar group that discharges in degradation process has again good hydrophily, the synergy of these factors makes the alms bowl body have good gas permeability, water penetration, and compression ratio, being conducive to improve the free penetrating of seedling root, compression ratio improves and also helps the volume that reduces the alms bowl body, be more convenient for transporting, and prevent loose alms bowl.In addition, the incomplete high glycan of degraded can also be in follow-up stock growing process in the digest process, and further for the microbial function bacterium in alms bowl body and the soil provides nutrition, nutrient is long deenergized period, and fertilizer efficiency is better.
In the later stage of material fermentation, i.e. make the temperature of material maintain 40 ~ 50 ℃ in the 5th ~ 8 day of fermentation beginning, higher fermentation temperature is conducive to the further decomposition of material.The grease degrading strains such as the bacillus subtilis of access this moment, bacillus licheniformis are except the grease in the coffee grounds of can degrading, can also produce subtilin, gramicidins isoreactivity material, synergy with higher fermentation temperature, pathogenic bacteria in the material there are obvious inhibition or killing action, are conducive to the stable of alms bowl body quality of material.
In order further to improve water conservation, the drought resistance of alms bowl body, the present invention has added water-loss reducer in composite operation, make the matrix nutrition alms bowl after moisture expantion, prolongs the moisture remaining time, play the effect that reduces irrigation times and drought-resistant moisture-preserving, be particularly suitable for the not convenient area in drought or water source and use.In addition, the adhesive that this stage admixes not only is conducive to the fixed-type of alms bowl body, especially after moisture expantion, still can make to keep between matrix connecting preferably unshaping.
