干旱和高温危害毛竹竹笋—幼竹生长初报

1985年4—5月份持续一个多月的高温、干旱,使安吉县毛竹重点产区的新竹眉围下降、产量骤减,残次竹增多,估计共损失竹材120余万支,损失产值200余万元。据我们分析,在毛竹笋期,高温和干旱,尤其是后者是造成竹林减产的主要原因。因此,除了在栽培方面着手研究抗旱保竹的技术措施外,在有条件的地方应发展灌溉,以尽可能减少损失。

FIRST REPORT ON HIGH TEMPERATURE AND DROUGHT DAMAGE SHOOTS AND YOUNG BAMBOOS(PH.PUBESCENS)

In April and May of 1985, high temperature and drought lasting more than month damaged main bamboo (Ph. pubescens) forests in Anji county. As a result, brow hight girth of bamboo droped, culm yield reduced and deficient bamboos increased. Based on our investigation, almost 1200000 bamboos losed, which value RMB 2000000 yuan. In shoot period, high temperature and drought, especially the latter, are main cauces damaging bamboo forests. Therefore, we'll bring the forest under irrigation to reduce damage as far as possible in some area, besides, we shall research a technical measure to combat drought and protect bamboos.
