为评价优良无性系在油茶品种改良中的作用及效果,对研究区主推的岑软、湘林系列品种进行产量及主要经济性状测定.结果表明,岑软系列+湘林系列混交造林3～4年后即可投产,比岑软、湘林系列早;岑软系列投产初期平均产果量331.95～7 952.50 kg/hm2,岑软系列+湘林系列混交造投产初期平均产果量612.00～2 363.15 kg/hm2,湘林系列投产初期平均产果量247.50 kg/hm2;岑软系列投产初期平均产油量35.75～504.98 kg/hm2,岑软系列+湘林系列混交造林投产初期平均产油量46.80～149.60 kg/hm2,湘林系列投产初期平均产油量20.55 kg/hm2.岑软、湘林系列及其混交林丰产期平均鲜出籽率均接近或超过40.00%,低于研究区品种(小籽油茶和孟江油茶);平均种仁含油率均超过45.00%,岑软、湘林系列及其混交林平均种仁含油率较高;岑软系列丰产期平均产果量5 906.40 kg/hm2,岑软系列+湘林系列混交林丰产期平均产果量5 842.50 kg/hm2,湘林系列丰产期平均产果量5 118.15 kg/hm2,比研究区品种增产133.83%～327.16%;岑软系列丰产期平均产油量399.15 kg/hm2,岑软系列+湘林系列混交林丰产期平均产油量370.35 kg/hm2,湘林系列丰产期平均产油量316.95 kg/hm2,比研究区品种增产71.65%～121.93%.因此,选择岑软、湘林系列无性系良种更新造林,产果量增加100.00%以上,茶油增产70.00%以上.
Analysis of the increasing yield effect of regeneration and afforestation of Camellia oleifera from Cenruan and Xianglin Series Clones
In order to evaluate the role and effectiveness of excellent clones in the improvement of Camellia oleifera varieties,the yield and main economic characteristics of the excellent clones Cenruan and Xianglin series promoted in the research area were determined.The results showed that the mixed afforestation of Cenruan series and Xianglin series can be put into production after 3-4 years,earlier than the Cenruan and Xianglin series.The average fruit yield of the Cenruan series in the early stage of production was 331.95-7 952.50 kg/hm2,the average fruit yield of the Cenruan series+Xianglin series mixed planting in the early stage of production was 612.00-2 363.15 kg/hm2,and the average fruit yield of the Xianglin series in the early stage of production was 247.50 kg/hm2;The average oil production of Cenruan series was 35.75-504.98 kg/hm2,the average oil production of Cenruan series+Xianglin series mixed afforestation in the initial stage was 46.80-149.60 kg/hm2,and the average oil production of Xianglin series in the initial stage was 20.55 kg/hm2.The average fresh seed yield of the Cenruan,Xianglin series,and their mixed forests during the high yield period was close to or exceeds 40.00%,which was lower than the varieties in the study area(small seed Camellia oleifera and Mengjiang Camellia oleifera).The average kernel oil content exceeded 45%,and the Cenruan,Xianglin series,and their mixed forests had higher average kernel oil content.The average fruit yield during the high-yield period of the Cenruan series was 5 906.40 kg/hm2,the average fruit yield during the high-yield period of the Cenruan series+Xianglin series mixed forest was 5 842.50 kg/hm2,and the average fruit yield during the high-yield period of the Xianglin series was 5 118.15 kg/hm2,which was 133.83%to 327.16%higher than the varieties in the study area.The average oil production during the peak production period of the Cenruan series was 399.15 kg/hm2,the average oil production during the peak production period of the Cenruan series+Xianglin series mixed forest was 370.35 kg/hm2,and the average oil production during the peak production period of the Xianglin series is 316.95 kg/hm2,which was 71.65%to 121.93%higher than the varieties in the study area.Therefore,the reforestation of the Cenruan and Xianglin series of clones had increased fruit yield by more than 100.00%and tea oil by more than 70.00%.
