| 摘 要： | 研究枇杷枝剪口密度(分别剪1、2、3、4、5、6、7个枝/m2,7个处理)对新梢生长及开花结果的影响。结果显示:不同剪口密度(剪1个枝/㎡除外)对枇杷新梢生长均有促进作用;每个剪口抽生的枝梢数均比对照多;新梢的长度和叶片数各处理(剪1个枝/㎡除外)均有增长和数量增多,与对照的差异均达极显著水平;剪4～5个枝/㎡抽穗率相对较高,开花较早,谢花所占的比例较低,而花穗质量也较理想,单果重、株产均有较大提高。表明剪4～5个枝/㎡效果最好。

| Abstract: | Loquat Eriobotrya japonica(Thunb.)Lindl.] trees were pruned at different densities(1,2,3,4,5 6,7 branches cut per square meter)to investigate the growth of new shoots and their blossom and fruitsetting.The results show that pruning at different densities except 1 branch cut per square meter was conducive to the growth of new shoots of the loquat;that the new shoots derived from each cut were higher in number than those of the control;that the length of the new shoots from each cut and their number of leave... |
