摘要
为解决传统堆肥产品功能单一、肥效较低的问题,以玉米秸秆与牛粪混合物为载体,枯草芽孢杆菌(Bacillus subtilis)和拟茎点霉B3(Phomopsis liquidambari B3)为接种微生物,采用二次接种发酵技术获得生物有机肥,并在田间栽培条件下评估其肥效。结果表明,玉米秸秆与牛粪混合堆肥过程中接种Bacillus subtilis和Phomopsis liquidambari B3可提高堆体最高温度,延长高温(>50℃)持续时间,缩短堆肥腐熟时间,加快堆肥进程。与不接种菌剂的传统有机肥相比,接种功能微生物的生物有机肥总养分和有机质含量分别增加了21.1%和23.8%,细菌和真菌数量分别提高626%和160%。小白菜栽培试验结果表明,施用有机肥能显著促进小白菜的生长和提升其品质,接种功能微生物的生物有机肥效果最好,小白菜产量比不施肥对照增加了95.2%,比传统有机肥处理增加了43.2%,可溶性糖和维生素C含量最高。接种功能微生物能够促进玉米秸秆与牛粪混合物快速发酵,堆制的生物有机肥品质优于传统有机肥。
To resolve the problems,such as single function,low utilizing efficiency,existing in traditional composting products,the compost test was conducted using mixtures corn straw and cow manure to prepare bio-organic fertilizer(BOFs) with the technology of second fermentation,which inoculated Bacillus subtilis and Phomopsis liquidambari B3. And then field experiment was used to evaluate the BOFs quality. The results showed that addition of Bacillus subtilis and Phomopsis liquidambari B3 inoculants could improve the highest temperature of compost,shorten the time of reaching high temperature(>50℃) and extend the high temperature sustaining time,accelerate the composting process and maturity. Compared to those in traditional organic fertilizer treatment,the content of total nutrient and organic matter in BOFs with microorganism inoculation treatment increased respectively 21. 1% and 23. 8%,meanwhile,the number of bacteria and fungus increased respectively 626. 0% and 160. 0%. The field experiment results showed that application of organic fertilizer could promote the quantity and quality of bok choy,while the effect of BOFs with microbial inoculation was best. Compared with that in the control and traditional organic fertilizer treatment,the fresh weight per plant in BOFs with microorganism inoculation treatment increased about 95. 2% and 43. 2%,respectively,and the content of soluble sugar and vitamin C were highest. Therefore,in the view of compost and field experiment,addition of Bacillus subtilis and Phomopsis liquidambari B3 could speed maturity of the compost and enhance compost quality.
