Each processing is sampled after compost and measures nutrient content, the results are shown in Table 5.It is each to handle in addition to CK and processing 1
For nutrient content after compost 4% or more, highest nutrient content is 4.51% to handle 5, is secondly processing 4, is
4.47%, handle 3,4,5,6 four processing total nutrient contents on there was no significant difference (P < 0.05)；To C/N ratio analysis it is found that
The C/N of each processing compost is below 20.
The nutrient content of 5 compost sample of table
3. the composting production content of organic matter is analyzed:
Each processing is sampled after compost and measures the content of organic matter, the results are shown in Table 6.Each processing content of organic matter by
Arrive greatly it is small successively are as follows: processing 6 (42.46%) > handle 3 (41.27%) > handle 5 (38.78%) > handle 2 (38.59%) >
It handles 4 (37.45%) > and handles 1 (33.87%) > CK (32.56%), wherein being produced after 2,3,4,5,6 five processing compost of processing
There was no significant difference for the product content of organic matter (P < 0.05), and processing 3 and processing 6 are apparently higher than control.
The content of organic matter of 6 compost sample of table
4. compost fermentation effect assessment:
Each processing is weighted according to 3 compost temperature index of table and standard and is divided equally, each comprehensive score that handles is shown in Table 7.
5 highest scorings are handled, is 8.5 points, is secondly scored at 8.1 points for processing 4.CK and the score of processing 3 are lower.
7 ferment effect evaluation table of table
(3) conclusion: cow dung and vegetables straw carry out the material proportion of compost as cow dung: fruit and vegetable stalk: corn stover 2: 1
: 1, compost effect is best.
(2) cow dung and vegetables straw environmental control parameters are studied:
(1) materials and methods:
1. material to be tested:
For trying cow dung: being provided by Beijing's Ao Genike Organic Fertilizer Plants, and dried in time, for adjusting material moisture.
For trying auxiliary material: collecting fruit and vegetable stalk in Shunyi District by Beijing's Ao Genike Organic Fertilizer Plants, dry and crushed.By
Beijing's Ao Genike Organic Fertilizer Plants provide mushroom residue.
Fermenting agent: the compost Inoculant provided by Beijing fertile soil world biotech inc.
Moisture recorder: can continuously monitor temperature, and can record the minimum and maximum temperature on the same day.
8 composting material spy's part of table
2. experimental design:
Compost material presses cow dung: vegetables straw: mushroom residue weight ratio is 2: 1: 1 progress compostings.By material moisture, turn over throwing
Two cow dung compost process influence factors of frequency carry out orthogonal design, and test process is shown in Table 9.
9 experimental design of table
3. testing ten thousand methods:
Ready cow dung and mushroom residue proportionally mix before testing, and add microbial inoculum, and microbial inoculum illustrates user by it
Method addition.It stirs evenly, the heap body of a height of 7.02.01.2m of length and width is made.After charging, it is inserted into thermometer in time,
Probe is asked to reach at heap body depth 30cm.
The heap temperature on 3 points of record same day of 10 points of every morning and afternoon, and turning is carried out to heap body according to test requirements document
Ventilation.After compost, its N-P-K content of taking sample determination.
According to the experience of test of many times, the compost effect of each processing is examined using method of weighting scores, is shown in Table 10.
10 compost Indexes of Evaluation Effect of table and standard
(2) result and analysis:
1. compost temperature is evaluated
China's decontamination of human excreta sanitary standard (GB7959-1789) regulation, highest compost temperature reach 50-55 DEG C and continue
5-7 days, compost reached innoxious standard.Shown in Fig. 2 and table 11, microorganism decomposition is using in material in compost initial stage compost
Organic matter carries out own metabolism and breeding, so amount of heat has been released, thus the heap temperature rate of climb is fast, respectively handles
For maximum temperature more than 60 DEG C, the continuous days that each processing reaches 50 DEG C two or more are respectively 15 days, 22 days, 19 days, 18 days, 13
It, 19 days.
Temperature change in 11 composting process of table
2. the variation of windrow organic matter in composting process:
Fig. 3 is the situation of change of the windrow content of organic matter in composting process.As can be seen that each processing originates the content of organic matter
Difference, in entire composting process, the content of organic matter is all gradually reduced as time went in six processing windrows.In difference
Different rules is presented in stage, and in compost initial stage organic matter degradation rate and unhappy, the degradation of organic matter occurs mainly in high temperature
It is phase, little in the variation of cooldown period organic matter, until each processing reduces respectively compared with the initial content of organic matter at the end of compost
22.6%, 56.7%, 26.5%, 41.5%, 5.6%, 9.7%.
3. the variation of windrow carbon-nitrogen ratio and T value in composting process:
Table 12 is the variation of each group windrow carbon-nitrogen ratio and T value before and after compost.It can be seen that respectively handling carbon nitrogen after compost
Than reducing, fall is respectively 41.9%, 47.2%, 40.7%, 23.3% and 25.4%.Carbon-nitrogen ratio is common compost
One of rotten degree evaluation, has and researchs and proposes: when solid carbon-nitrogen ratio is reduced to 20 or less from initial 25-30 in heap body, it can
Think that compost is substantially decomposed.Windrow carbon-nitrogen ratio obtains T value divided by initial carbon-nitrogen ratio by the end of, reaches when T value is less than 0.6
To decomposed, so processing 1-4 reaches decomposed, 5,6 compost effects of processing are poor.
Table 12 respectively handles the variation of windrow carbon-nitrogen ratio and T value
4. respectively processing nutrient content compares:
Each processing is sampled after compost and measures nutrient content, the results are shown in Table 13.After each processing compost
For nutrient content 4% or more, highest nutrient content is 5.55% to handle 3, is secondly processing 1 and processing 4, is
5.40%.
Respectively processing nutrient content compares table 13
5. compost fermentation effect assessment:
Each processing is weighted according to 3 compost temperature index of table and standard and is divided equally, each comprehensive score that handles is shown in Table 14.
3 highest scorings are handled, is 7.8 points, is secondly scored at 7.2 points for processing 4.The score of processing 5 and processing 6 is lower.
14 ferment effect evaluation table of table
6. respectively processing CO2 discharge is compared:
Fig. 3 is each processing CO2 discharge figure, it can be seen that each compost treatment CO2 discharge is presented one and first increases to be declined afterwards
Trend, reach highest in the megathermal period of compost, be gradually reduced in cooldown period until gentle, wherein handling six CO2 concentration of emissions
It is higher.
(3) conclusion: compare in conjunction with each processing compost fermentation effect assessment and gas discharge, filter out cow dung and vegetables straw
The suitable environment control parameter for carrying out compost is initial water content 60%, turns over and throws frequency 1 times a week, compost effect is best.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
