摘要
盆栽试验表明，氮素化肥和有机肥对水稻生物学特性影响差异明显。按同等养分量施化肥比单施有机肥明显增产；有机肥施用达到一定量后可以提高土壤中氮素含量，而化肥对于土壤氮素提高不明显。
Pot experiment results showed there were the different effects of various fertilizer application on biologicalproperties of rice. Chemical fertilizer treatment produced more grain than manure treatment under equal nutrientapplication condition. Enough manure application could improve soil nitrogen content, but chemical fertilizer contributed less to soil nitrogen level.
