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 is a species of small cane that has a wide distribution and high commodity value in our country. After many years of research and popularization, it has accumulated more technical information and has become one of the main cultivated species of rattan in southern China. White rattan has a typical cluster, the total stem length of the rattan directly affects the yield per unit area. It is reported that the bush planting can increase the total stem length of rattan clumps, so as to obtain a higher yield per unit area. However, increasing the number of initial plants in the plantation will affect the number of sprouts and the growth of the stems. Then, only to determine a reasonable number of early-cotyledons in order to make full use of space, improve yield per unit area, without causing the plant sprout and the growth of the stem is greatly affected. For this reason, early in 1985, we planted white cabbage plants trials, the early results are reported below.
