摘　　要：为给油茶产业化发展提供科技技术支撑,研究了不同修剪时间、修剪强度对油茶优良无性系采穗圃穗条数量、长度和抗病性等的影响。研究结果表明,修剪强度、修剪时间对抽梢数量和长度有显著影响,中、轻度修剪能促进树枝抽梢数的增加和穗条延长,重强度修剪能抑制树枝抽梢数和穗条的生长;采穗圃最好的修剪强度是轻度修剪,最佳的修剪时间是夏冬2次联合修剪;修剪能有效防治新梢病害的发生。In order to provide technological support for Camellia oleifera industrialization development,effects of different pruning time and intension on number,length and resistance of cuttings were researched in superior C.oleifera clones cutting orchard.The results showed that pruning time and intension had significant effects on number and length of new shoots,the pruning at middle and light degree could promote increasing of new shoots number and growth of new shoot,and the pruning at serious degree could control number of new shoots and growth of cuttings.The pruning at light degree in summer and winter was fit for cutting orchard.Pruning could effectively control occurrence of disease in new shoot.
