the using method of composite fungus agent and effect
By above embodiment, the composite fungus agent being made up of the flat lead fungi of yellow spore, trichoderma harziarum, subtilis, 4 kinds of bacterium of glue peptone sample gemma bar is described, there is the effect of several functions, can be used as decomposing agent and carry out the quick composting of vegetable castoff.
One, the using method of composite fungus agent
1, adjust the carbon-nitrogen ratio (25~30:1) of vegetable castoff and moisture (55~60%, with hand one hold hand seam drip be advisable), every 5 side's vegetable castoffs add 1 kilogram of composite fungus agent, turn over and smash evenly.
2, by trapezoidal vegetable castoff heap growth good pre-treatment, 1 meter of heap top width, 2 meters of heap bottom width, pile 1.2~1.5 meters of high summer and autumns, 1.5~2.0 meters of winter-spring season, and heap is long to be determined according to place, and every heap volume is no less than 5 sides.
3, after fermentation starts, in the time that temperature of charge (20~30 centimetres of depths) rises to 55 DEG C, keep three days, then turn over and smash once.If fermentation initial stage temperature does not rise, adjust moisture to recommendation ratio and turn over every day and smash once until pile temperature rising.
4, when heap temperature rises to after 55 DEG C again, keep three days, then turn over and smash once;
5, turn over and smash according to heap tender feeling condition afterwards, temperature rise is not turned over and is smash period, and temperature stops rising and turns over and smash, and repeat this step, until heap temperature is identical with external temperature, moisture is while being down to below 30%, complete fermenting process, whole fermentation period is generally 15~25 days.
Two, the result of use of composite fungus agent
1, materials and methods
Composting material: pulverize dry eggplant stalk, dry cucumber seedling sprout, Chinese cabbage leaf
If two processing, add the composite fungus agent described in the present invention and the blank (CK) with microbial inoculum, each processing raw material 5 sides, outdoor composting, measures heap temperature every day.Fermentation period calculates gained till being down to room temperature with leavening temperature.
2, results and analysis
The impact of composite fungus agent on compost initial stage temperature and maturity.
Table 6 compost initial stage temperature and complete the number of days of fermenting process
Table 6 shows, the compost of inoculating compound bacterium agent, the 2nd day temperature all higher than do not connect bacterium (contrast) compost (, and temperature just reaches more than 45 DEG C after 2 days, and temperature to the 4 talentes of contrast rise to more than 45 DEG C.The time that composite fungus agent completes fermentation only needs 25 days, and the contrast need that do not connect bacterium are more than 50 days.The compost of inoculating compound bacterium agent, than contrast 2 days phases that reach a high temperature in advance, completes fermentation time and reduces 35 days than contrast.
embodiment 7:
application composite fungus agent is produced made organic substrate and effect
Under certain site facility condition, by adding compound decomposing microbial inoculum, vegetable castoff generation biological degradation, chemical degradation and physical change, produce CO 2, H 2o and NH 3deng gas release of heat, generate in a large number and can be transformed and absorb micromolecular inorganic and organic nutrient substance by crop, form stable physical structure and state, obtain organic substrate of the present invention.
One, the production of organic substrate and technique
1, raw material and formula
Raw material comprises dry eggplant stalk, dry cucumber seedling sprout, dry Chinese cabbage leaf and four kinds of organic materialss of brown coal.By weight, eggplant stalk accounts for 40~60%; Cucumber seedling sprout accounts for 20~40%; Chinese cabbage leaf 5~15%; Brown coal 5~15%.
2, material choice
Lignite humic acid content >=50%.
3, proportioning raw materials
Take by weight 40~60% dry eggplant stalk, 20~40% dry cucumber seedling sprout, 5~15% dry Chinese cabbage leaf and 5~15% brown coal.
4, the mixing of raw material
The eggplant stalk taking by weight, cucumber seedling sprout, Chinese cabbage leaf and brown coal forklift are fully mixed.
5, add water
By water: the weight ratio of mixing raw material 1:1 adds water, control water content in 50~60% left and right.
6, add composite fungus agent of the present invention
Every 5 side's vegetable castoffs add 1 kilogram of composite fungus agent
7, the specification of banking up
To regulate water and add the vegetable castoff heap growth of composite fungus agent trapezoidal, 1 meter of heap top width, 2 meters of heap bottom width, pile 1.2~1.5 meters of high summer and autumns, 1.5~2.0 meters of winter-spring season, and heap is long to be determined according to place, and every heap volume is no less than 5 sides.
8, the control of turning time
After the fermentation of banking up starts, if fermentation initial stage temperature does not rise, as inadequate in moisture content, adjust moisture to recommendation ratio 50~60%, as excessive in moisture content, must turn over every day and smash once, increase oxygen content in buttress, impel microorganism Fast Growth, until heap temperature rises.In the time that temperature of charge (20~30 centimetres of depths) rises to 55 DEG C, keep three days, then turn over and smash once, in order to killing harmful pathogenic micro-organisms such as disease and pest, worm's ovum and weeds insect.When heap temperature rises to after 55 DEG C again, keep three days, then turn over and smash once.Turn over and smash according to heap tender feeling condition afterwards, temperature rise is not turned over and is smash period, and temperature stops rising and turns over and smash, in the time that temperature exceedes 70 DEG C, need turn over and smash immediately, eliminate the inhibition of high temperature to microorganism growth by cooling, thereby impel the activity of a large amount of mesophilic bacterias, accelerate the process of compost.
9, turning requirement
Turn in buttress process and will accomplish tune, even, broken.Adjusting is exactly original top section in buttress to be transferred to earth's surface become underclad portion, and underclad portion is transferred to top layer and is become top section, to reach the object of abundant fermentation; Even is exactly that buttress Raw is mixed to also inhomogeneous part, again mixes work; Broken is exactly that the massive zymolysis thing of formation is during the fermentation carried out to fragmentation work.
10, fermentation termination control
Heap temperature is identical with external temperature, moisture is while being down to below 30%, outward appearance chocolate, and odorless, has completed the whole fermentation production process of organic substrate, and the whole cycle is generally 15~20 days, 25~30 days time in winter.
11, fermented quality control
After having fermented, pulverize, sieve, detect, weigh and pack, organic substrate has been produced, and organic requirement reaches 45%~55%, and excrement colibacillus group number is negative, induced worm egg death rate 100%.
Because described composite fungus agent integrates xylogen decomposition, cellulose decomposition, disease-resistant and bacterial manure several functions, add after vegetable castoff material, probiotics decomposes on the one hand the vegetable castoff that becomes thoroughly decomposed and forms stable organic substrate, utilize vegetable castoff to carry out self expanding propagation on the one hand, in the organic substrate generating, make the organic substrate generating there is equally the multiple performances such as disease-resistant and bacterial manure own disease-resistant and bacterial manure function transplanting.
12, using method
As 100~200 kilograms of every mu of amounts of application for soil improvement agent, before ploughing, spread fertilizer over the fields and earth's surface, then following ploughs is evenly manured into soil and interiorly uses as base manure; Can be used as seedling medium uses.
Two, seedling growth test
Trial crops is tomato, surveys percentage of germination.
Test design: establish two processing: 1, invent described organic substrate, 2, market matrix (contrast); Repeat for three times, order is arranged.Test-results is as shown in table 7:
Table 7 biological organic fertilizer field effect
Process Seedling rate (%)
Process 1 92
Contrast 91
Test-results shows, organic substrate of the present invention can be used as good seedling medium, and seedling rate reaches 92%, substantially the same with organic seedling raising matrix seedling rate effect on market.
