| 摘 要： | 本文利用多年生黑麦草（冬景）,采用锯末、珍珠岩、腐殖叶为基质,研究不同施肥水平下,N、P、K三种元素对其成坪的影响,结果显示,草坪成坪速度施磷肥＆gt;钾肥＆gt;氮肥,最佳的处理是TP3仅需36d;三种元素不同处理水平下,对密度、盖度、分蘖数的影响不大;对生物量的影响依元素种类和浓度梯度而有差异;地上部分生物量,氮肥贡献率最大,钾肥居中,磷肥影响较小。

| Abstract: | Perennial ryegrass(Winter Scape)as material was studied to observe forming turf effect in different levels of fertilizer(N,P,K),using sawdust,perlite,humic leaves as culture substrate.The results showed that: forming turf speed is Phosphate>potash>nitrogen,the optimal treatment is TP3(36d).Density,coverage,little have no significant difference in different treatment levels.According to the elements of the type and concentration,among underground biomass have difference.Nitrogen contribution rate is the larg... |
