岑软ZJ11等油茶无性系在环江县的早期生长情况调查

Survey of Camellia oleifera Clones Cenruan Series at the Early Growth Stage in Huanjiang County,Guangxi

为了解岑软ZJ11等4个油茶无性系在广西环江县的生长表现,对其幼林期的生长情况进行了调查。结果表明:岑软ZJ11等4个无性系适应当地气候条件,能正常生长,在树高、地径和冠幅方面,均不逊于当地普遍种植的原有良种岑软3号;种植第4年岑软ZJ24的单株花芽率达95.13%,而且单株花芽数量也较多;种植第5年,岑软ZJ24和岑软3-62的平均单株结果量分别比对照岑软3号提高26.57%和11.72%,而岑软ZJ11和岑软ZJ14则显著低于对照。因此,初步判定岑软ZJ24和岑软3-62更适合在当地推广种植。

In order to understand the growth performance of four clones of Camellia oleifera in Huanjiang county,Guangxi,a survey was made of their growth at young growth stage.The results showed that four clones were adapted to the local climate conditions and grew normally.The four clones were not inferior in tree height,ground diameter and crown width to the original clone Cenruan 3 that is widely cultivated in this area.In the fourth year of planting,the flower bud rate of Cenruan ZJ24 was 95.13%with high number of flower buds per plant.In the fifth year of planting,Cenruan ZJ24 and Cenruan 3-62 produced higher average fruit yield per plant than Cenruan 3,which were 26.57%and 11.72%higher,respectively,while Cenruan ZJ11 and Cenraun ZJ14 were significantly lower in fruit yield than the control Cenruan 3.Therefore,it is preliminarily concluded that Cenruan ZJ24 and Cenraun 3-62 are more suitable for local cultivation.
