摘要
进行了测土配方施肥技术在早稻上的应用效果试验。结果表明:测土配方施肥明显促进水稻分蘖,提高有效穗数,实粒数、千粒重均高于常规施肥区和缺肥区。增施N、P、K肥的增产效果都达到显著水平,比常规施肥增产15.92%,对产量影响顺序为钾>氮>磷。
The application effect of formula fertilization by soil testing on early rice was conducted. The result showed that the rice tillers and effective spikes could he promoted by formula fertilization. The filled grains and 1 000-grain weight in formula fertilization by soil testing plot were higher than that in normal and lack fertilizer plots. The yield was significantly increased by applying N, P and K fertilizer with the increment of 15.92% compared to the normal fertilizer plots. The influence order of fertilize to yield was K o N and P fertilizer.
