【摘要】 为了研究环剥技术对油茶当年开花结实和翌年坐果率的影响，于2019年，在湖南省常德市鼎城区许家桥回维乡对湘林40号低龄良种油茶林进行环剥试验，对油茶当年生叶片的黄化程度、新梢落花情况和第2年坐果率等进行观察测定。结果表明：与对照相比较，环剥后当年采收的油茶单果重无显著差异，对油茶当年开花也无显著影响；显著提高翌年坐果率(P<0.05)。表明环剥对低龄良种油茶当年的坐果和开花没有负面影响，还能显著提高翌年坐果率。研究结果可应用于油茶幼树整形，并促进良种油茶结果初期产量的稳步提升。更多还原

【Abstract】 In order to study the effect of Girdling technology on the flowering and fruiting of Camellia oleifera in the current year and the next year′s fruiting rate, the yellowing degree and the dropping of new shoots of the current year′s leaves, and the effect of the second year′s fruiting rate of Xianglin 40,an excellent clone of Camellia oleifera,were observed in 2019.The results showed that there was no significant difference in fruit weight and flowering of Camellia oleifera in the same year after Girdling.In the next year, the rate of ring-stripping was higher than that of control group, and the difference was significant by T-test, P<0.05.The results showed that Girdling had no negative effect on the fruit setting and flowering of low-age Camellia oleifera varieties in the current year, and could significantly increase the fruit planting rate of the next year, which could be used for shaping low-age Camellia oleifera trees on a large scale and promote the steady increase of the initial yield of improved Camellia oleifera varieties.更多还原
