氮磷钾硅肥对香稻培杂软香产量及品质的影响

Effect of Nitrogen、Phosphorus、Potassium and Silicon on Yield and Quality of Peizaruanxiang

研究了施用氮、磷、钾和硅对培杂软香产量及品质影响。以杂交香稻培杂软香为材料,采用四元二次回归正交旋转组合设计。结果表明,大田产量、有效穗、整精米率随着施氮肥水平的提高而提高;大田产量、有效穗、千粒重随着施磷肥水平的提高而下降;施钾肥对大田产量,有效穗,每穗总粒数,结实率无明显影响;整精米率、垩白度随着施硅水平的提高而下降。

This thesis studied on the effects of the usage of massive elements which included nitrogen,phosphorus,potassium and silicate on yield and quality of one aromatic hybrid rice combination,PeizaRuanxiang.Using quaternary return to the second rotation combination design.The results showed that,with increase of nitrogen fertilizer level,yield,effective panicle and whole grain rice rates enhanced,With increase of phosphorus fertilizer level,yield、effective panicle and 1000-grain weight droped,the potassium chloride fertilizer levels had no obvious influence to the yield,the effective panicle,the grains per panicle and the burliness rate,With increase of silicate fertilizer levels,the whole grain rice rate and the degree of chalkiness droped.
