摘要
研究了施用生物菌肥对水稻根系活力的影响 ,讨论了不同施肥处理与土壤养分可持续性指数的关系 .结果表明 ,施用生物菌肥有利于土壤磷素可持续指数的上升 ,施用生物菌肥的同时必须配施足量的化学氮肥和钾肥 。
The effect of application bacterial manure to power of rice root was studied,the relationship between different fertilizer treatment and sustainability index of soil nutrients was discussed.The results showed,application bacterial manure was propitious to ascend of sustainability index of soil phosphorus,only application bacterial manure as a time application quantum sufficient nitrogenous fertilizer and potassium fertilizer,can stabilize rice yield and step by step improve soil fertility.
