摘要
在鄂油油茶品种示范林中开展整形修剪试验,采用轻度修剪、中度修剪、重度修剪三种方式,研究不同修剪措施对油茶产量和果实经济性状的影响。结果表明:开张树形适宜中度修剪,增产幅度为51.55%,直立树形适宜重度修剪,增产幅度为67.62%。整形修剪对油茶果实性状也有一定影响,中度修剪可提高鲜出籽率,重度修剪后可增加平均单果重。
The pruning techniques had been applied on“Eyou” Camellia oleifera .Three methods including medium prun‐ing ,moderate pruning ,heavy pruning were used as experimental treatments .The influences of different pruning measures on fruiting yield and non-timber characteristic were studied .The result indicated that the fruiting yield of tree with open shape could be raised 51 .55% by medium pruning ,the fruiting yield that of tree with upright shape could be raised 67 . 62% by heavy pruning .Pruning also had effected on the economic characteristics of fruit ,and medium pruning could be improve the yield of fresh seeds ,and heavy pruning could be enhance the weight of each fruit .
