| 摘 要： | 以鸭粪为主要材料,添加芦苇皮、水草等不同调理剂进行高温堆肥试验,研究了不同配比条件下堆肥体系的温度、pH、C/N、种子发芽指数(GI)的动态变化及其对废弃物堆肥品质的影响。结果表明,鸭粪与芦苇皮混合堆肥效果最好,堆体升温快,4d达到50℃,高温维持时间为15d,最高温度达70℃,堆肥30d后,油菜种子发芽指数高达90.48%;鸭粪与水草混合堆肥效果较差,高温维持阶段仅8d,最高温度为57℃;纯鸭粪单独堆肥效果最差,16d达到50℃,高温维持时间为6d,最高温度仅为53℃,到堆肥结束44d,油菜种子发芽指数刚达到80.67%。4种混合配料堆肥产品全氮、全磷、全钾含量都有所增加,其中鸭粪与芦苇皮配比增加率最大,分别为15.90%、11.53%和29.94%。综合以上结果,说明添加秸秆类有机质含量较高的调理剂可加快堆肥的腐熟进程,同时减少营养元素的流失,利于养分的保存,保证了堆肥产品的品质。 |

| Abstract: | The composting experiment was conducted to study the dynamics of indices(temperature,pH,carbon(C)/nitrogen(N) ratio,seed germination index) during composting process using duck manure mixed with reed skin or(and) aquatic plants.The results showed that the composting of duck manure mixed with reed skin was the best treatment and appeared the special properties of temperature and seed germination index of cabbage during composting.In this treatment,the temperature increased rapidly to 50 ℃ on the fourth day and the highest temperature was 70 ℃,even high temperature could maintain for 15 days.In addition,germination index of cabbage seeds in compost could be up to 90.48% after composting for 30 days.And the composting of duck manure mixed with aquatic plants was poor,high temperature could maintain only for 8 days and the highest temperature was 57 ℃.The composting effect of control(duck manure composting only) was the worst one.Until the 16th day,the temperature increased to 50 ℃ and the highest temperature was 53 ℃.However,high temperature could only keep for 6 days.Cabbage seed germination index was only 80.67% on the last day of composting.Moreover,the contents of nitrogen,phosphate and potassium were measured to illustrate the quality of the composts from four treatments.Compared to the raw materials before composting,the contents of N,P and K in mature composts of four treatments increased.The compost from the treatment of duck manure mixed with reed skin had higher contents of N,P and K.The increased proportions of N,P and K accounted for15.90%,11.53% and 29.94%,respectively. |
