不同施肥措施对红哺鸡竹生长的影响

Growth Responses of Phyllostachys iridescens to Fertilizations

红哺鸡竹是高产、优质的笋用竹种。试验中采取施用无机肥、生物有机肥、种绿肥与不施肥等不同措施,结果是采用A处理(劈山+全锄)和D处理(种绿肥)在发笋数、成竹数及平均胸径、平均竹高相差不大,而B处理(劈山+全锄+化肥)和C处理(劈山+全锄+生物有机肥)的效果明显优于A、D处理,特别是C处理(劈山+全锄+生物有机肥)对发笋数、成竹数及平均胸径、平均竹高等促进效果最好。为红哺鸡竹的丰产培育及绿色栽培提供了依据。

Phyllostachys iridescens is a kind of bamboo used for producing bamboo shoots with high yield and quality. The experiment of different fertilization treatments, including treatment A （cleaving down the shrubs ＋ hoeing down the weeds） . treatment B （cleaving down the shrubs ＋ hoeing down the weeds ＋ chemical fertilizer） , treatment C （cleaving down the shrubs ＋ hoeing down the weeds ＋ bio- organic manure） and treatment D （Green manure）, was conducted to study the growth responses of Phyllostaehys iridescens to the different fertilization methods. The results showed that the number of bamboo shoots, the bamboo euhns and their average diameter and height in treatment A and D were almost the same while in the treatment B and C the growth responses were significantly greater than that in the treatment A and D, especially in the treatment C. The results provided the powerful data for the cultivation of Phyllostachys iridescens
