右江河谷区水稻测土配方施肥对比试验初报

A comparison experiment of rice formula fertilization by soil test modes in valley district of Youjiang River

水稻测土配方施肥对比试验结果表明:在右江河谷平原区按照施N 12kg/667m2;P2O56kg/667m2;K2O 9kg/667m2的配方施肥,不仅可以促进水稻的生长发育,使植株长势良好,叶色浓绿,熟期转色好,有效穗多,成穗率高,每穗总粒数和实粒数多,结实率高,增加稻谷产量;同时降低水稻的生产成本,提高水稻种植经济效益,值得应用推广。

The experiment results show that in Youjiang valley district,the fertilization formula of N 12kg/667m2;P2O5 6kg/667m2;K2O 9kg/667m2 can promote not only rice growth by features of deep leaf green,good-looking of mature period,more effective ears,higher grains/ear full-grain/ear,higher yield etc.,but also reduce production cost and enhance economic effect,so that it is worth to be extended in large scale.
