| 摘 要： | 目的]探讨板栗废弃物制备有机肥技术的可行性。方法]以板栗废弃物(玉米秸秆为对照)和牛粪为主要高温好氧堆肥原料,尿素和微生物菌剂为辅料,以pH、有机质、全氮、全磷、全钾、速效氮、铵态氮、腐殖酸、重金属、微生物、蛔虫卵等为指标,研究板栗废弃物和牛粪好氧堆肥的最佳配比。结果]板栗废弃物与牛粪的干重比为5∶5的配方处理,总养分含量、铵态氮占速效氮比例及水溶性腐殖酸占总腐殖酸比例分别达6.98%、96.9%和14.6%,重金属、微生物及蛔虫卵均达到国家相关标准的要求。结论]板栗废弃物与牛粪干重比以5∶5较适宜。

| Abstract: | Objective] To explore the feasibility of preparing organic manure from Castanea mollissima waste. Method] Using chestnut waste (corn stalk control) and cattle manure as the main raw material of urea high temperature aerobic composting, and microbial agents as auxiliary materials,with pH value,organic matter,total nitrogen,total phosphorus,total potassium,available nitrogen,ammonium nitrogen, humic acid,heavy metals,microbial,ascaris eggs etc. as the index,the best ratio of the waste and cattle manure aerobic composting of chest-nut was studied. Result] In the treatment of chestnut waste and cattle manure dry weight ratio of 5 : 5,nutrient content, the proportion of ammonium nitrogen and available nitrogen,the proportion of water soluble humic acid and total humic acid ratio reached 6.98%,96.9%, and 14.6%,heavy metals, microbial and ascaris eggs have reached the requirements of the relevant national standards. Conclusion]The proportion of dry weight ratio of chestnut waste to cow dung is 5:5. |
