Prediction Model for the Bamboo Shoot Yield of Phyllostachys makinoi Hayata

A prediction model for the shoot yield of Phyllostachys makinoi Hayata was established based on the data of shoot yield of the sample plots.The principles of quantitative theory I was adopted to analyze 13 factors which had influence on the shoot yield such as culm density,silvicultural operations etc.The complex correlation coefficient t test is extremely significant,with the result of standard error rate E test being 13.1%,reaching the precision prescribed.The establisbed model can be used to predict the bamboo shoot yield of Ph.makinoi.Furthermore,the results of partial correlation coefficient t test demonstrate that such factors as bamboo stand structure,site condition,cultural operations,and bumper or on off year etc,have apparent influence on the shoot yield of Ph.makinoi.
