摘要
在垦复、施肥等集约培育的纸浆毛竹林中，实施砍伐４、５年生竹（竹龄均为周年），竹材产量与砍伐６、７年生竹的一般材用竹林相若，差异不显著。在竹林生长季节的３、６、９月伐竹，与一般材用林的大年１２月伐竹相比，竹材产量差异也不显著，但小年１２月伐竹产量降低较多，生产上应避开这个季节伐竹。以相对产量计，大年６月或９月伐竹，比１２月伐竹竹材产量有增加的趋势。纸浆毛竹林实行一年砍伐１次、２次、３次及４次的不同频度（砍伐时间为３月、６月、７月、８月、９月和１２月）砍伐试验，对竹林产量的影响与大年１２月一次砍伐相比差异均未达到显著水平。
There is no obvious difference of the culm yield between culm cutting age of 4～5 and 6～7 years old in the bamboo stands,which are intensively cultivated by soil digging and fertilization. Compared with culm cutting time of December in on year in a common timber bamboo stands,the culm cutting in growing season of March,June and September makes no significant difference in culm yield. But,the great yield decrease will be caused by the cutting in December of off year when should be refrained from culm cutting. As to the relative yield, there is a tendency to be higher by cutting in June or September than in December. The stands yield by cutting times of 1,2,3,4 respectively in one year(March,June, uly,August, September, December)has no significant difference from that by one time cutting in December of a on year.
