有机水稻施用有机肥控制杂草技术的研究

摘要

The weed control experiment of using fermented chicken dung applied at different stage with different dosage in rice field was conducted.The results showed that fermented chicken dung could efficiently control weed.And the organic fertilizer applied twice got a better efficiency than applied once.Also the yield was higher when the organic fertilizer applied twice than once.%本研究利用有机水稻栽培普遍施用的发酵鸡粪,采用不同使用时期和不同施用量的方法进行水田杂草控制试验。结果表明：发酵鸡粪能够有效控制杂草的发生;并且控制杂草效果,分施两次比一次性施用效果好;水稻产量也是施用两次比施用一次高。
