为了探索“一年栽竹,三年成林,五年取材,十年高产”的毛竹速生丰产技术措施,我场于1958年12月9日选定蒿山工区一块土层深60公分以上、排水良好、PH6.5、砂质壤士的丘陵平山熟荒地,面积1.78亩,栽竹98株,成活率达98%,栽后三年累计出笋成竹741株(即1959年为142株,1960年为261株,1961年为338株),基本上新竹满园。从第五年林地清理开始到目前为止已经取材达1693株。我们在1970年12月18日进行了林分调查,当时宅竹蓄积保存766株,其中1966年新竹最粗围度12寸,折算总产量为22513市斤,亩产12647.7市斤。在1974年11月24日又进行了林分调查,现在毛竹蓄积保存985株(其中一伐竹444株,二伐竹29株,三伐竹374株,四伐竹12株,五伐以上的156株),折算总产量为38131市斤,亩产14117市斤,
In order to explore the “one year planted bamboo, three years of forest, five years of material, ten years of high yielding” bamboo quick-growing techniques, my field on December 9, 1958 selected Artemisia area a soil depth of more than 60 cm, Drainage well, PH6.5, sandy soil hillside Pingshan heath, an area of 1.78 acres, planting 98 plants, the survival rate of 98%, three years after planting bamboo shoots 741 (that is, 1959 to 142 261 in 1960 and 338 in 1961), basically Hsinchu Manchu. Up to date, up to 1693 strains of woodland have been taken from the fifth year of forest clearing. We conducted a stand survey on December 18, 1970, when 766 strains of bamboo house were preserved, of which the 1966 Hsinchu area was 12 inches thick with a total output of 22,513 kg and a yield of 12,647.7 kg per mu. On November 24, 1974, another survey was conducted. At present, there are 985 preserved bamboo stocks (of which 444 are planted bamboo, 29 planted bamboo, 374 planted bamboo, 12 planted bamboo, 156 strains), total output of 38,131 kg conversion, 14117 kg per mu,
