| Abstract: | From the end of October to the beginning of November in 2015 and 2016,150 soil samples were collected from Camellia oleifera stands in twenty counties of 6 main producing regions of Zhejiang province.Determinations were made on 13 indicators of fertility,such as total nutrients,available nutrients and microelements,etc.Principal component analysis on total data set demonstrated that the minimum data set included the following six indexes,total nitrogen,phosphorus,exchangeable calcium,exchangeable magnesium,available copper,and available iron.The fertility index was standardized by parabolic shape function,and the minimum data set fertility index was calculated according to weight coefficient.The correlation analysis showed that the fertility index of minimum data set had significant positive correlation with annual tea oil yield,and extremely significant positive correlation with nemero comprehensive index. |
