影响毛竹笋用林竹笋产量有诸多因子,究竟那个是主要的不甚明确,本文试图用灰色系统理论,对诸因子的关联度进行分析。结果表明,立竹量和平均胸径对产量的影响明显高于施肥量,当每亩立竹量为180—220株,平均胸径为7厘米时,配合施肥等措施,可获得较大的增产效益。采用关联度分析法,具有计算简单、工作量小等优点,适用于多因子分析,在生产上有一定实用价值。
There are many factors affecting the yield of bamboo shoots for bamboo shoots. After all, the main one is not very clear. This paper attempts to analyze the correlation degree of various factors by the gray system theory. The results showed that the amount of standing bamboo and the average breast diameter had a significantly higher effect on the yield than the amount of fertilizer. When the amount of bamboo per acre was 180-220 and the average diameter at breast height was 7 cm, . The use of correlation analysis, with the advantages of simple calculation, small workload, suitable for multi-factor analysis, in the production of a certain practical value.
