15个油茶种源栽培技术及产量分析

Cultivation Techniques and Output Analysis of Fifteen Provenances of Camellia oleifera

介绍了油茶林的栽培技术,并分析其平均单株产果量。结果表明,在15个油茶种源中,岑软油茶的平均单株产果量为7.46 kg,明显高于其他种源;其次是龙胜毛茶、常山霜降籽、衡东大桃、安徽大红,其平均单株产果量分别为6.18、5.59、5.44、5.20 kg,而其他种源的平均单株产果量较低,不适宜在桂林产区种植。在油茶生产发展中,除选择种源外,选择种源的良种更重要,要使其达到丰产稳产,必须选用适宜该地区的良种,定植后加强抚育、施肥与病虫害防治等,促进油茶植株生长旺盛。

Cultivation techniques of Camellia oleifera forest were introduced, and average output of fruint per plant was analyzed. The study showed that in the fifteen provenances, the best was Cenruan Camellia oleifera,its average output of fruit was 7.46 kg and significantly higher than others. The next were Longsheng raw tea, Changshan frost seed,Hengdong grand peach and Anhni bright red,their mean output of fruit were 6. 18,5.59,5.44 and 5.20 kg respectively, while average output of fruit of the rest of provenances were the lower, so they were not suitable for plant- ing in Guilin. In the production of Camellia oleifera, not only selecting provenance was important ,but also improved variety was more important. In order to achieve high and stable yield ,the improved variety that was suitable for local was important. Besides ,for the sake of promoting growth of Camellia oleifera,we should take scientific management methods after planting, such as strengthening tending, fertilization, prevention and con- trol of plant diseases and insect pests and so on.
