慈竹(Sinocalamus affinis (Rendle)McClure)是四川盆地主要速生用材竹种之一,面积约50万亩,目前年产竹材12.5万吨左右。由于竹林零星分散,竹秆壁薄中空,对竹林资源和生产效果的评定比较困难,在以往资源清查中,只进行面积和株数的统计,缺少重量指标,而慈竹的产销计价,多以重量为准,因此研究其秆形变化与重量的规律,编制竹秆重量表,对竹林资源和生产效果的评定,用竹杆重量表即可获得竹材重量。我们于1983年在合江地区进行了初步研究。
Sinocalamus affinis (Rendle) McClure is one of the main bamboo species for rapid growing in Sichuan Basin. It covers an area of about 500,000 mu and currently produces about 125,000 tons of bamboo. Due to sporadic scattered bamboo, thin bamboo hollow wall, the evaluation of bamboo resources and production efficiency is more difficult in the past, the inventory of resources, only the area and number of statistics, the lack of weight indicators, production and marketing of the price of cicadas, and more weight Therefore, the rule of stalk change and weight was studied, the weight of bamboo stalk was compiled, and the evaluation of bamboo resources and production efficiency was made. We conducted a preliminary study in Hejiang in 1983.
