Simultaneously for proving the effect of high temperature gemma cellulose-decomposing bacteria, the method (method of becoming thoroughly decomposed is heaped in the whole strain of maize straw original position) that applicant adopts with claim 3 is tested, take Natural compost as reference, (mode of banking up of the maize straw of Natural compost is identical with test method with quantity, but do not cover film, not with microbial inoculum, urea and magnesium sulfate) carry out simultaneous test, content of the test is as follows
1, microbial population and quantity
Table 1 is can culturing micro-organisms population and number change in composting process.Result shows, before test, isolates 14 kinds of bacteriums from maize straw, 7 kinds of fungies, 4 kinds of actinomycetes.In the stalk material of processing in test, the pliotherm period, (35 microbial populations d) significantly reduced, and only isolate 2 strain bacteriums (wherein 1 strain is the high temperature fiber genus bacillus of inoculation), 1 fungal strain and 1 strain actinomycetes; After becoming thoroughly decomposed, (90 d), and microbial population increased than pliotherm period, isolates 9 kinds of bacteriums, 2 kinds of fungies, 2 kinds of actinomycetes.In the stalk material of Natural compost (contrast), the microbial population of pliotherm period than compost before slightly reduce, bacterium, fungi and actinomycetes are respectively 11 kinds, 5 kinds and 3 kinds; Front without significant difference with test while banking up 90 d.
2. temperature contrast
As seen from Figure 1, after compost experiment starts, the thermometer of stalk material reveals obvious temperature raising period, pliotherm period, cooldown period.Wherein, approximately 5 ~ 7d of temperature raising period; In the pliotherm period, the temperature of stalk material, between 50 ~ 64 ° of C, approximately maintains 50d; Heap postpone 57d temperature is down to 50 ° below C, 80d after compost, and the temperature of stalk material is down to similar to temperature.But, in Natural compost process, the temperature of stalk material at 5th ~ 70d higher than temperature, but medial temperature than test process low 20.5 ° of C, and fluctuation larger.
3. moisture contrast
Before banking up, the water content of maize straw is 63.4%, and in composting process, the water content of material continues to reduce, and is down to steady state value (23.8% ~ 24.6%) after the 80d that banks up.But in the processing of Natural compost, the water content of precipitation affects material, is generally wave and reduces.Heap postpone 90d, the water content of heap body material is down to 43.1%, is significantly higher than test and processes (Fig. 2).
4.pH contrast
Fig. 3 is visible, and in test is processed, the pH value of stalk material continues to reduce, and the pH value that test is processed is significantly lower than Natural compost.In the time that compost finishes, the pH value of compost material is respectively pH6.14(test and processes) and pH6.42(Natural compost).
5. outward appearance, organic matter and nutrient
Adopt this test to process, along with the increase of the time of banking up, the color of maize straw changes grey, beige, brown, chocolate, volume-diminished into gradually by yellow.While banking up 90 d, maize straw is all chocolate, for chip or Powdered, becomes thoroughly decomposed completely.In the process of Natural compost, while banking up 90 d, maize straw gray or beige, there is tephrosious bacterial plaque on stalk surface, although volume reduces, substantially keeps original form, is difficult to fracture, and becomes thoroughly decomposed not good.
Adopt this test process, while banking up 90 d, the active organic matter of stalk material, nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide content are followed successively by 43.35%(data problem), 1.26%, 0.57% and 1.85%.In Natural compost process, the organic matter of the 90d that banks up, nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide content are followed successively by 33.47%(data problem), 0.72%, 0.46% and 1.74%, all significantly lower than test process.
Can be found out in composting process by above-mentioned test, adopt high temperature gemma cellulose-decomposing bacteria to make organic matter generation mineralising and the humify of material, temperature, moisture, pH and carbon-nitrogen ratio etc. are closely related with microbial activities and compost quality.In test is processed, access high temperature fiber decomposer, can increase the quantity of high temperature resistant organism of fermentation; The carbon-nitrogen ratio of adding urea reduction maize straw, can meet microorganism Carbon and nitrogen nutrition needs; Epiphragma can keep temperature of charge, prevents rainfall ponding, reduces the detrimentally affect of envrionment conditions, and these are all of value to microbial activities, promotes compost fermentation.
At the hot stage of compost, high temperature microbe is the most active, organic mineralising rapidly dehydration; Cooldown period mainly carries out humification, and the two is all critical periods that compost fermentation is produced fertilizer.In test is processed, the temperature of stalk material raises rapidly, shows the obvious pliotherm period, the pliotherm period of 50 ° of C approximately maintains 50 d, be up to 64 ° of C, be not only of value to the rapid mineralising of organic matter and the natural-dehydration of stalk material, and pathogenic microbe killing effectively.After inoculation high temperature fiber bacterium, quick heating, approximately 5 ~ 7 d; In the pliotherm period, the microbial population in stalk material significantly reduces, but microbe population significantly increases, and the overwhelming majority is bacterium.Microbe inoculation accelerated warming is described, the pyrolytic decomposition of stalk organic matter is relevant with high temperature resistant bacterium, and the stalk that microbe inoculation has participated in the pliotherm period decomposes.So, producing in the process of fertilizer at field compost treatment entirety maize straw, inoculation high temperature fiber bacterium has unusual effect.。
In test is processed, material moisture when compost finishes and pH are significantly lower than Natural compost, but organic matter, nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide content are significantly higher than Natural compost, and be chocolate and crumb powder state, illustrate that maize straw is after test is processed, the degree of becoming thoroughly decomposed is better than Natural compost.In tobacco planting process, chemical fertilizer and stalk fertilizer are joined in right amount to execute and are significantly improved yield of flue-cured tobacco and the output value, and improve quality of tobacco.Wherein, 50% chemical fertilizer joins that to execute yield of tobacco, average price and the output value of 50% stalk fertilizer the highest.In addition, join in the processing of executing stalk fertilizer at chemical fertilizer, nicotine content significantly reduces, and tobacco leaf potassium, total reducing sugar, sugared alkali ratio and schmuck value significantly improve, and sugared alkali ratio and schmuck value remain on respectively between 11.80 ~ 12.67 and 4.30 ~ 4.42.The content of the chemical composition of tobacco leaf and ratio thereof are the objective standards of its quality of reflection, directly affect the quality of quality of tobacco.Wherein, potassium can improve the incendivity of tobacco leaf, appropriate sugar make flue gas mouthfeel alcohol and, fragrance is dense, too high protein and nicotine produce assorted taste, pungency increases.The sugar degree of cigarette product improves and increases with grade, and protein mass reduces with grade raising, therefore schmuck value is larger, quality of tobacco is better.Sugar alkali is than the ratio that is total Soluble Sugar and nicotine content, for reacting the soda acid Harmony of tobacco leaf.The sugared alkali of general tobacco leaf is than better in 10 ~ 13 scope.Join in the processing of executing at chemical fertilizer and stalk fertilizer, potassium content in tobacco leaf, total reducing sugar, schmuck value and sugared alkali, than improving, illustrate the coordination of cigarette chemical composition, quality improvement.The soil in Guizhou Province mostly is acidity-neutral yellow earth, and effectively potassium content is generally not high, and the foggy few light of weather, is unfavorable for tobacco leaf sucrose accumulation, uses the alternative chemical fertilizer of maize straw fertilizer, mends potassium and increases sugar, improves quality of tobacco.
In sum, prepare in fertilizer process inoculation high temperature fiber bacterium at field compost treatment entirety maize straw, add urea and magnesium sulfate, covering agricultural film is of value to enhancing microbial activities, promotes organic mineralising and humify, promote that maize straw becomes thoroughly decomposed, improve compost quality.In flue-cured tobacco cultivation, 50% chemical fertilizer is joined and is executed 50% stalk fertilizer and can significantly improve yield of tobacco, average price, the output value, improves quality of tobacco.
