Investigation and Analysis on Fruit Yield of Camellia oleiferaStands in Zhejiang

Investigations and determinations were implemented on fruit and oil yield of Camellia oleifera stands with different plantation methods in21 productive counties of Zhejiang province from 2013 to 2015. The result demonstrated that there were 166,000 hm2 of C. oleifera plantation,among them, 43,000 hm2were planted with new culitars. About 80% plantation were distributed in Lishui and Quzhou city, with low yield. Plantationwith 6-8-year new cultivars had higher yield and economic benefit than the mean one of transformed plantation, Plantations in Qingtian county hadthe mean highest yield in the province. Correlation analysis on yield and site condition of plantation showed that the yield had negative relation withslope gradient(r=0.271, Sig=0.009). Simple linear regression analysis on slope and yield resulted as Y=340.61-5.299X. Suggestions on the futuredevelopment were put forwarded, such as increasing the area of new cultivars, researching and promoting mechanized production.
