采用大田试验研究水稻覆膜栽培条件下复合肥配施有机肥（榨菜叶）对水稻产量、养分吸收量和利用率的影v向。结果表明：水稻覆膜栽培条件下减少复合肥施用量20％，较CK（淹水栽培）增产6．9％，在此基础上配施有机肥较CK提高水稻产量14-3％～19．0％，水稻氮、磷、钾养分利用率提高4．7～26．1百分点。在紫色土水稻产区覆膜栽培条件下复合肥减量20％及有机肥15～30t/hm2是水稻节肥增产的有效途径。

The effects of compound fertilizer applied with organic fertilizer （pickle leaves） on the yield, nutrient absorption and utilization rate of film mulching cultivation rice are studied by field test. The results show that, the yield of film mulching cultivation rice with reducing the compound fertilizer application amount of 20% fertilizer is increased by 6.9% as compared with that of CK （flooded cultivation） .When compound fertilizer applied with organic fertilizer, the rice yield is observably increased by 14.3%-19%, and the utilization rate of nitrogen, phosphorous and potassium is increased by 4.7-26.1 percentage points compared with CK. It is a highly effective way for improving the rice yield and economizing the fertilizer that the compound fertilizer application amount is reduced by 20% and applied with 15- 30 t/hm2 organic fertilizer in the purple soil field of film mulching cultivation rice.
