| 摘 要： | 通过鸡粪、麦秸高温好氧堆肥,对接种VT菌剂与空白处理堆肥过程进行物理化性质、微生物指标分析比较,研究接种VT菌剂对堆肥过程的影响,并在玉米、青菜、花卉进行肥效试验,分析堆肥效果。结果表明:在堆肥降温阶段接种VT菌比空白处理温度下降缓慢,接种处理温度高于空白的温度;接种处理比空白处理的C/N值降幅大;在堆肥中接种处理的细菌、酵母菌和放线菌的数量均比空白多,真菌数量差别不大,并且纤维素酶和脲酶活性均比空白的高,接种能使堆肥中微生物数量增多及活动强度增大;在玉米和油菜产量和品质等指标上,接种处理略好于空白堆肥处理;同时接种比空白处理的花卉观赏性强。因此,接种VT菌剂可促进堆肥有机物质分解及利用,有效杀灭病原菌,加快堆肥腐熟,提高堆肥产品质量。

| Abstract: | Effects of VT microbes on compost produced by chicken manure plus wheat straw were studied in the present experiments.Two disposal methods with or without inoculation of VT microbes were designed.The composting process lasted for 24 days with 0.2% inoculating VT microbes in the compost.The physical,chemical and microbiological indexes of the composts in process,the mechanisms of VT microbes in mixture accelerating composting process were studied.In field test of maize,brassica and begonia,fertilizer efficiencies were compared with and without inoculating.Though these tests,it has been indicated that inoculation of VT microbes could lead to higher composting temperature,slowing temperature decline rate in late maturing period,lowering C/N ratios compared with the treatment without VT microbe addition,It also was found the numbers of bacteria,fungi,microzyme and actinomyces were larger and the content of cellulose and urease activity were higher in the inoculated composting than that with no inoculating treatment.The test of fertility of composting products showed that more yields and higher quality of maize,brassica and more view and admire of begonia in the inoculated treatment than with no inoculation.That means inoculating VT microbes in the compost enhanced microbial activity and abundantly decomposed and used organic matter,thus,it led to higher temperature and better composting quality.It may be suggested that inoculating VT microbes in composting process be effective to decompose organic matter,raise temperature,shorten composting time,and increase composting quality. |
