摘要
本文主要分析了利用城市生活垃圾研制的有机肥施用于绿菜花对其产量、品质、经济效益以及对土壤的残药量和肥力的影响。结果表明,施用垃圾肥对绿菜花增产、增收效果显著。适当配施无机肥,优于单施垃圾肥,并且优于等养分含量的化肥。从经济效益角度,L、G、F3个配施无机肥的处理效果最显著,但由于G、F处理中无机肥消耗量大,成本较高,从大面积推广和绿色食品角度考虑,L处理最优,用垃圾肥土培育的绿菜花,从残药和亚硝酸盐含量方面分析,远低于国家颁布的绿色食品标准。而垃圾肥本身以及施用后土壤的残药量均十分安全。且对提高土壤肥力的作用十分明显。为绿色食品需求提供了很好的肥源。
this artical is about effects of urban disposed garbage fertilizer. When we use the garbage fertilizer in brassica oleracea , it can make great influence. First , it can make great effects for Brassica Oleracea ' s output quality and economic benefits. Second , it exercises great influence to the fertility of soil. Third , it can reduce remnants of pesticide of soil. The garbage fertilizer compound with some chemical fertilizer can make better effect than garbage fertilizer itself. The Brassica Oleracea' s contain of nitrite and remnants of pesticide reach domestic green food stan- dard. This garbage ferilizer is a kind of organic fertilizer for producing green food.
