摘要
以广东省樟木头林场60多年生广宁红花油茶Camellia semiserrata人工林为试验材料,采用样地和抽样调查的方法研究广宁红花油茶的生长性状、果实产量、果实经济以及数量性状。结果表明:广宁红花油茶地径、树高、冠幅分别为24.0 cm、7.9 m、5.0 m。每625 m^(2)的样地保存有广宁红花油茶24~42株,单株间地径、冠幅变异较大,树高变异较小。每667 m^(2)平均鲜果产量为295.7 kg,单株最大为30.1 kg,最少的无果,变异大。果实鲜出籽率、种子含油率、种仁含油率、鲜果含油率分别为11.8%、36.61%、63.11%、2.88%,每667 m^(2)可产鲜籽34.6 kg,产油8.5 kg。
Taking about 60-year-old Camellia semiserrata plantation in Dongguan Zhangmutou Forest Farm of Guangdong as the test material,the growth characteristics,fruit yield,fruit economic and quantitative traits were investigated by sample plots and sampling method.The results showed that the average ground diameter,height,crown of C.semiserrata in sample plot were 24.0 cm,7.9 m,and 5.0 m,respectively.There were 24-42 C.semiserrata trees being preserved in each 625 m^(2) sample plot.The variation of ground diameter and crown width among individual plants was large,while the variation of height was small.The average fresh fruit yield was 295.7 kg per 667 m^(2),while the maximum yield of single tree was 30.1 kg and the minimum was fruitless.Hence,the variation of the average fresh fruit yield was very large.The average fresh seeds content,the oil content of drying seeds,drying kernel,and fresh fruit were 11.8%,36.61%,63.11%,2.88%,respectively.And the average yield of fresh seeds and oil per 667 m^(2) were 34.6 kg and 8.5 kg,respectively.
