通过测定草末堆肥过程中的体积、重量、pH值、EC值、含水量、硝态氮含量、氨态氮含量和发芽指数等物理、化学指标的变化,研究了添加已腐熟堆肥扣EM菌对草末堆肥过程的影响。结果表明:草末堆肥体积和重量变化较大,特别是前7d体积减少很快,后期变化减弱。草末中添加腐熟堆肥可以控制堆肥臭味,减少氮损失,降低堆肥的pH值和EC值,减少结块,提高堆肥的品质;草末堆肥时添加EM菌也起到一定消除臭味作用;建议使用已腐熟堆肥作为草末堆肥的配料,草末和已腐熟堆肥以3:2的体积比混合.EM菌可视成本和操作便利情况酌情添加。
通過測定草末堆肥過程中的體積、重量、pH值、EC值、含水量、硝態氮含量、氨態氮含量和髮芽指數等物理、化學指標的變化,研究瞭添加已腐熟堆肥釦EM菌對草末堆肥過程的影響。結果錶明:草末堆肥體積和重量變化較大,特彆是前7d體積減少很快,後期變化減弱。草末中添加腐熟堆肥可以控製堆肥臭味,減少氮損失,降低堆肥的pH值和EC值,減少結塊,提高堆肥的品質;草末堆肥時添加EM菌也起到一定消除臭味作用;建議使用已腐熟堆肥作為草末堆肥的配料,草末和已腐熟堆肥以3:2的體積比混閤.EM菌可視成本和操作便利情況酌情添加。

The effects of finished compost and EM microbes on composting process of turfgrass clippings was studied by determining the changes of volume, weight,pH value, EC value, moisture content, NH4+-N, NO3--N and sprouting index. The results showed that the bulk and weight of turfgrass clippings on composting lost fast,especially 7 d before the composting,then changed slowly.The turfgrass clippings adding finished compost could control odor,reduce nitrogen losses during composting,reduce the pH and EC value, reduce agglomerate and improve the composting quality. Adding EM microbes also could eliminate odor during composting. In production,adding finished compost on turfgrass clippings in composting process of which the ratio was 2:3 ,and EM microbes could be added or not by considering the cost factors and operation convenience.
