The yield effects of different nitrogen and potassium fertilizers application of no-tillage and cast transplanting in double continuous cropping late rice was studied.The results showed that application of fertilizer-N improved the rice tillering capability and leaf area index,increased the pructive panicle number and reduced the productive tiller percentage,increase of fertilizer-K approprio increased the pructive panicle number and the productive tiller percentage.The a-NA oxidation ability of rice root in late growth stage and content of chlorophyll in flag leaves after heading of N application treatments were higher than those of CK.The dry matter accumulation increased along with fertilizer-N rate increase,but the harvest index decreased;At the same N level,effect of increase of fertilizer-K application appropriately on the dry matter accumulation was low,while increased N-recovery efficiency.The N-recovery increased with N-application rate at first,amount to highest level at moderate N level,then decreased obviously at high N level.The fertilizer-N physiologyical efficiency and fertilizer-N agronomic efficiency decreased with fertilizer-N rate increase.The effect of no-tillage and cast transplanting rice was the along best when the N,K application rate were 150 kg/hm2 and 160 kg/hm2,respectively.
