据省林调队1976年调查,全省现有竹林面积56万多亩,其中淡竹林达20多万亩,占全部竹林面积的五分之二,等于毛竹林面积的五分之四,每年提供的竹材达200万担左右.这说明,建立我省竹林基地,淡竹是一个不容忽视的竹种.而在这些淡竹林中,有五分之三系社员个体所有,亩产在10～20担之间,产值都高达200～400元.但尽管如此,若与兄弟省河南洛宁丰产淡竹园相比(每亩立竹1990株,胸围平均22厘米,年产量11144斤,每亩蓄积55720斤),仍有很大的差距,生产潜力很大.为此,我们开展了结构试验.现将2～3年来积累的试验区当前生育指标的一些参数作如下分析研究.
According to the survey conducted by the provincial forestry transfer team in 1976, the existing bamboo forest area in the province is more than 560,000 mu, of which more than 200,000 mu are light bamboo forests, accounting for two-fifths of the total bamboo forest area, equal to four-fifths of the area of the bamboo forest each year Bamboo provided about 2000000. This shows that the establishment of our province bamboo base, light bamboo is a bamboo species can not be ignored.In these light bamboo forest, three fifths of the members of the Department of all, per mu in 10 to 20 In between, the output value is as high as 200 ~ 400. However, if compared with the fraternal province Luoning, Henan Province, Abundance and Chuk Yuu Garden (1990 per mu of bamboo stand, average bust 22 cm, annual output 11,144 pounds, 55720 acres per acre There is still a big gap between the two and there is still a great potential for production. Therefore, we conducted a structural test, and now we will analyze and analyze some parameters of the current fertility index in the experimental area that have accumulated in two to three years.
