摘要: 通过开展甬优9号“3414”肥效试验,摸清甬优9号养分吸收量和肥料利用率等基本参数,为科学施肥提供依据。试验蛄果表明:甬优9号施用氮、磷、钾肥的增产效果排序是:氮肥〉钾肥〉磷肥,同类土壤最佳施肥量N、P2O5和K2O分别:12.91kg/667m^2、1.11kg/667m^2和3.82kg/667m^2。

Abstract: By the experiment of fertilizer efficiency of Yongyou No.9(3414),the paper gets the basic parameters such as nutrition absorption and fertilizer efficiency,The findings of the study are important references for precision fertilization. The results reveal that nitrogen fertilisors is better than phosphorus on Yongyou No.9 (3414),while the field-increasing effect of potash fertilizer lies somewhere in between.On the basis of some similar soil,the optimum fertilizer of N,P205 and K20 are:12.91kg,/ 667m^2,1.11 kg/667m^2 and 3.82kg/667m^2.
