四川省万岭菁楠竹林枯枝(死)状况是严重的。1987～1990年系统研究表明,楠竹林老年竹枯枝(死)主要是由经营因素导致的,占63.87％。虫害和病害是壮年竹株枯枝(死)的主要原因,占15.64％。 为了进一步验证楠竹林枯枝(死)的主要综合因子,采用多元回归和数量化理论(Ⅰ)方法,通过电子计算机运算。建立了多元回归予测方程和数量化理论(Ⅰ)予测模型,供生产应用。 Sichuan Province Wan Ling Jing Nan bamboo dead (dead) is serious. From 1987 to 1990, systematic studies showed that the aged and dead branches of Phyllostachys pubescens forest were mainly caused by operating factors, accounting for 63.87%. Pests and diseases are the main reasons for the dead bamboo branches (15.64%) in the primeval year. In order to further validate the main comprehensive factors of the deadwood in the bamboo grove, the method of multiple regression and quantification (Ⅰ) was used to compute by computer. Established a multiple regression equation and quantitative theory (Ⅰ) prediction model for production applications.
