Abstract

The effects of combined application of N,P and K on rice yield were studied.The results showed that under the conditions of equual P and K amount,when the dose of N in rice was higher than 21.0 kg/667 cm2,the yield-increaseing effect N,P and K fertilizer reasonable application of the N,P and K fertilizer resonable appleication of N,P and K fertilizer effect on rice yield and itscomponent factors.
