摘要
通过在锦屏县平略镇平略村进行冲沟细砂泥田水稻配方施肥试验结果表明最佳施肥量为N肥13.5kg/667m2、P2O57.5kg/667m2、K2O 10.51kg/667m2,产量665.25kg/667m2,最佳施肥配比为N∶P∶K=1∶0.556∶0.779。
An experiment of soil testing and formulated fertilization on rice has been conducted in the gully fine sandy mud paddy field in Pinglue village,Pinglue Township,Jinping County. The results show that optimum amount of fertilization is 13.5kg/667m2,p205 7.5kg/667m2,K20 10.51kg/667m2, with yield of 665.25kg/667m2. Relevantly, optimum ratio of fertilization should be N：P：K=l：0.556：0.779.
