摘要
3种肥料对木薯产量和经济效益的影响结果表明:与不追肥的对照比较,追施撒可富复合肥、BGA土壤调理剂和微生物发酵鸡粪肥分别增产鲜薯22.1%、46.1%、55.0%,其中,追施BGA和鸡粪肥增产达到显著水平;撒可富和BGA的肥料产投比均为1.9倍,而鸡粪肥的产投比为3.8倍,因此,在木薯生产中推荐施用鸡粪肥。并提出降低BGA生产成本及BGA配方施肥等建议。
The experiment results of 3 kinds of fertilizers on cassava field and economic benefit showed that,comparing with no fertilizer （CK）, fresh cassava root yield of applying Sakefu compound chemical fertilizer,BGA soil conditioner,microbe fermented-chick manure increased 22.1%, 46.1% and 55.0% respectively, the increasing effect of BGA and microbe fermented-chick manure was significant. The output-input ratio of Sakefu and BGA were 1.9 times, the output-input ratio of microbe fermented-chick manure was 3.8 times, so chick manure was recommend to use in production of cassava. By the way,some suggestions were proposed to reduce production cost of BGA and combine application of BGA with chemical fertilizers etc.
