摘要
为了验证新型水溶肥料在水稻上的应用效果,采取对比试验的方法客观评价其在水稻上的肥效和作用效果。结果表明:于水稻破口期和孕穗扬花期每667 m2各喷一次大量元素水溶肥料(N+P2O5+K2O≥50.0%,Zn+B:0.2%-3.0%)50 g兑水30 kg(稀释600倍)叶面喷施,和每667 m2微量元素水溶肥料(Fe+Mn+Zn+Cu+B≥100g/L)50 g兑水30 kg(稀释600倍)叶面喷施,均可显著增加产量,且这两个处理之间没有显著差异。这两种水溶肥料均可使水稻的植株生长健壮、收获时熟相好,宜在生产中推广应用。
In order to verify the applied effect of new water-soluble fertilizers, the test of fertilizer efficiency was made and the result indicated that the new water-soluble fertilizer which were diluted by a factor of about 600 by 50 g fertilizer of（N＋P2O5＋K2O ≥50.0%,Zn ＋B：0.2%-3.0%） and（Fe ＋Mn ＋Zn ＋Cu ＋B ≥100g/L） adding water 30 kg was used on foliar application can increase yields significantly, and there were not significantly difference between two treatment. The two new water-soluble fertilizers can make plants growing strong and maturing phase get well, so they were suitable for extended application.
