摘要： 通过兰引3号结缕草肥效试验,分析了施肥对植株养分吸收量的影响。结果表明,在成坪期,随着N、P、K肥用量的增加,植株对养分吸收量呈逐渐增加的趋势。相关分析结果表明,地上部N吸收量与施N量呈极显著相关(r=0.8858),地下部N吸收量与施N量之间呈极显著相关(r=0.7463);K吸收量与施K量之间相关不显著,而与施N量呈极显著相关(r=0.7921);氮肥能促进植株对钾的吸收。

Abstract: A study of the fertilizing effect on Zoysia japonica Steud.cv.Lanyin No.3 shows that while forming a turf and with increased applying of fertilizers N,P,K,the plants tend to intensify the absorbing of nutrition.The absorption of N by the stems and leaves correlated positively with the N fertilizer applied(r=0.8858),while the roots absorption of N is even more obvious(r=0.7463).The correlation of absorption and fertilizing of K is not markedly discerned.The correlation of N absorption and fertilizing is notable(r=0.7921).Nitrogenous fertilizer promotes the plants’ absroption of potash fertilizer.
