在广西昭平县潴育潮沙泥土上进行水稻测土配方施肥试验,采用田间小区试验方法研究N、P、K、Zn、Si及Ca对水稻产量及农艺性状的影响。试验结果表明：N、P、K合理配施具有显著的增产效果,中微量元素对水稻产量的影响效果较为突出,不施N、P、K水稻减产79.5%,在配施N、P、K的基础上加施锌肥和硅钙肥分别增产4.9%和4.1%。
在廣西昭平縣潴育潮沙泥土上進行水稻測土配方施肥試驗,採用田間小區試驗方法研究N、P、K、Zn、Si及Ca對水稻產量及農藝性狀的影響。試驗結果錶明：N、P、K閤理配施具有顯著的增產效果,中微量元素對水稻產量的影響效果較為突齣,不施N、P、K水稻減產79.5%,在配施N、P、K的基礎上加施鋅肥和硅鈣肥分彆增產4.9%和4.1%。

A plot experiment of soil-test and formulation fertilization was conducted on water-logging gley sand soil in Zhaoping County of Guangxi,for N,P,K,Zn,Si and Ca＇s impact on rice yield and agricultural characters.The results showed that rational application of N,P,K had an obvious yield-increase effect.Especially the mediate and micro elements had the outstanding effect for yield.Without N,P,K application would reduce yield by 79.5%,and on the basis of N,P,K application,additional fertilization of Zinc,Si Ca would increase yield by 4.9% and 4.1% respectively.
