摘　　要：以7年生油茶的4个品种为对象开展冬季修剪和春季修剪,研究修剪对油茶果实经济性状的影响,结果表明:修剪能提高油茶果实的单果重、果径、单果籽粒数、籽粒大小、出籽率和含油率,且冬季修剪对各指标的提升效果优于春季修剪;冬季修剪的平均单果重达28.4 g,分别比春季修剪和对照的平均单果重高3.3 g和5.9 g;春季修剪的鲜果出鲜籽率和鲜果出干籽率分别为36.7%和19.6%,分别显著高出对照28.3%和41.0%,但与冬季修剪的差异不显著;冬季修剪和春季修剪的鲜果含油率分别为6.0%和5.0%,分别比对照高出62.2%和35.1%;不同品种对修剪的反映效果不一样,主要表现在不同的修剪时间的各经济指标的高低变化趋势差异较大。The research study on the effect of pruning on economic characters Camellia oleifera fruit with fourbreeds of Camellia oleifera which was seven years. The results showed that the fruit weight, fruit width, fruitseed number, seed size, seed-producing percentage and oil content were improved with pruning, and theimproved effect of winter pruning was superior to spring pruning. The average fruit weight of winter pruningwas 28.4 g, which exceed 3.3 g and 5.9 g respectively than spring pruning and the control. The fresh fruitproduced fresh seed percentage and fresh fruit produced dry seed percentage of spring pruning were 36.7%and 19.6% respectively, which exceed 28.3% and 41.0%, but which was not significant difference to winterpruning. Fresh fruit oil content of winter pruning and spring pruning were 6.0% and 5.0% respectively, exceed62.2% and 35.1% respectively. Different breeds had different effect, which the economic index difference of different pruning period was biggish.
