Preliminary Experimental Study On Introduced 'Hua' Series Of Camellia Oleifera In Liuzhou,Guangxi

Camellia oleifera Abel is an important woody-oil plant in China.With the development of Camellia oleifera industry,the proportion of camellia oleifera in existing edible oil supply will be greatly increased.As the national and local governments attach great importance to camellia-oil industry,the area of Camellia oleifera in China is also gradually increasing.The"Hua" series Camellia oleifera varieties refer to the excellent varieties of huashuo,huajin and huaxin camellia oil bred by central-south university of forestry and technology,which can produce more than 900kg/hm2 oil in the peak production period.These varieties have been widely cultivated and applied in hunan,jiangxi,hubei,guizhou,sichuan and other provinces.Guangxi is the main cultivation area of Camellia oleifera in China,and the third major production area of Camellia oleifera after hunan and jiangxi."Hua" series cultivars have been successfully introduced only in Sanjiang county in northern guangxi,but there is no report on the introduction and cultivation in central and southern guangxi.In this project,NO.3 of Cenruan,the main cultivar of guangxi,was used as the control to carry out an experimental study on the introduction of 3 cultivars of Huashuo,Huajin and Huaxin in liuzhou,guangxi.The main research results are as follows:1.There was no significant difference in the growth between Huashuo,Huajin,Huaxin and NO.3 of Cenruan.It showed that under the same business management level and the site environment,the four differential growth in test varieties were not significant.The "Hua"series Camellia oleifera varieties introduced varieties for the testing of the climate environment conditions and site environment adaptability,all aspects of the resistance with the localfine varieties of NO.3 of Cenruan are the same.2.The yield of Camellia oleifera in the 4-year old test forest was determined during the initial production period,on the Fruit yield per mu,seed yield rate of fruit,fruit-oil rate and other physical properties showed that the Huashuo variety was superior.After analysis of variance and multiple comparisons,the variation coefficients of fruit-setting rate,ground diameter,fresh fruit weight,fresh fruit seed rate and fruit-oil rate of the four varieties were all less than 20%,indicating that the growth amount and related economic characters of the four Camellia oleifera varieties were relatively stable.According to the average value and maximum value of each character,the comprehensive performance of Huashuo is more superior.Among the three introduced varieties,Huashuo is the best growth,the highest yield and the most stable yield.3.The determination of the chemical composition about the three varieties of Camellia oleifera showed that the content of oleic acid,linoleic acid and stearic acid in the three varieties of Camellia oleifera after the introduction was basically the same as the performance data in hunan,.There is not significant change.It shows that the chemical properties of the cultivar do not change although the environment change.As a result,it is more suitable to popularize and apply.
