摘要
白藤(Calamus tetradactylus)是我国分布广、商品价值较高的小茎藤种,经多年研究和推广试种,积累了较多的技术资料,目前已成为我国华南地区主要栽培藤种之一。白藤具有典型的丛生性,藤丛的总茎长直接影响到单位面积产量。据报道,丛栽可以增加藤丛总茎长,从而获得较高的单位面积产量。然而,增加植丛的初植株数将会影响植株的萌蘖数和萌茎生长。那么,只有确定合理的藤丛初植株数,才能既充分利用空间,提高单位面积产量,又不致使植株的萌蘖及萌茎生长受到较大的影响。为此,1985年初我们对白藤进行丛栽试验,现将早期结果报道如下。
Calamus tetradactylus Hance, a native of South China, is one of the small-sized rattan species with commercial value. A study on group-planting (1, 3, 5 seedlings planted in one group respectively) was carried out at Jinkeng Forest Farm, Guangzhou, in March 1985. The effect of the different treatments of group-planting is discussed with reference to the stem growth, sucker shoot formation and length of stems. The results of 4 years after planting showed that the rate of mother stem growth was higher in single planting than in group-planting with no significant difference. However the sucker shoot formation per motherplant and the growth of shoot stems per clump showed significant difference between the treatments of group-planting. The total stem length and the number of stems per clump increased obviously with the number of seedlings planted.
