在广西省钦州市钦南区康熙岭镇屯窝村进行水稻测土配方施肥试验,采用田间小区试验方法研究氮、磷、钾和硫酸锌、硅钙肥的配合使用对水稻产量及农艺性状的影响。试验结果表明:氮、磷、钾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,不施氮、磷、钾水稻减产,在配施氮、磷、钾的基础上加施锌肥和硅钙肥均能增产。 Rice soil testing and fertilization experiments were carried out in Tuenwo village, Kangxi ridge town, Qinnan District, Qinzhou City, Guangxi Province. Field experiment was conducted to study the effects of nitrogen, phosphorus, potassium and calcium sulphate fertilizers on yield and agronomic characters of rice influences. The results showed that reasonable application of N, P and K had significant effects on the yield increase, while the effects of trace elements on rice yield were more prominent. The yield of N, P, K decreased with the application of N, P and K Addition of zinc fertilizer and calcium silicate fertilizer can increase production.
