为探讨桂中双季稻区磷肥施用效应，2009年在广西进行了不同施磷水平对该地区早稻与晚稻的肥效试验。结果表明，与不施磷（P0）相比，早稻施磷处理产量平均提高9．83％，晚稻产量平均提高16．03％，而且当施P2O5量≤525kg／hm^2时，水稻产量随着施磷水平的增加而提高。可见，在桂中双季稻区适当增施磷肥是保证水稻高产稳产的主要措施之一。

In order to discuss the effect of phosphate fertilization in double cropping rice of middle area of Guangxi, the effect of phosphate fertilization on double cropping rice under different phosphorous fertilization levels in Guangxi in 2009 is tested. The results show that： the yields of early rice and late rice with phosphate fertilization compared with no phosphate fertilization （P0） are increased by 9.83% and 16.03%. When the phosphate fertilization （P2O5） amount is less than 525 kg/hm2, the yield of rice is increased with phosphate fertilization level. Thus phosphate fertilization is an efficient method for double cropping rice with high and stable production in middle area of Guangxi.
