摘要
应用国家重大科技专项"滇池流域面源污染控制技术研究"成果"双室堆沤肥系统",设计使用双室堆沤肥不同的4种处理方式施肥。对施肥前后的作物产量、作物品质、土壤肥力进行对比研究,选出双室堆沤肥和无机肥配施的还田应用的最优施肥处理。处理B施肥方式(双室堆沤肥,化肥减施30%)对增加作物产量、提高作物品质、增加土壤肥力效果最好。
The fruit named ＂Dual - chamber Composting Reactor System＂ from the major national scientific and technological project of ＂Research on Non -point Source Pollution Control Technology for Dianchi lake＂ is applied to design the four different kinds of fertilizing treatments based on the dual - chamber composting heap. The impacts of different fertilizations on crop yield and crop quality and soil fertility for exploring the best use method of dual -chamber composting heap produced by Dual -chamber Composting Reactor System are researched. The results show that the fertilization of treatment B which is composed of dual - chamber composting heap and liquid additional fertilizer and 30% of chemical pesticides could obviously increase crop yield and crop quality and soil fertility.
