有效光合辐射截获量是决定柿树生长发育和经济产量的一个基本因素。在光照强度为1.0000—100.000米烛光范围内和25—31℃气温条件下,柿树光合强度随光强增加而提高。本试验研究了相对光强对桔蜜柿的营养生长和开花结果的影响。试验结果表明,随着树冠内相对光强的减弱,枝量、果枝率,枝势,叶子发育状况和开花结果率相应下降。为提高枝量、花量和座果率,应对现行的乔化大冠树体结构,从骨干枝数量,树冠厚度和树冠形状上加以调整和改造.
Effective photosynthetic radiation interception rate is to determine the growth and development of persimmon and economic output of a basic factor. Under light intensity range of 1.0000-100.000 m and 25-31 ℃, the photosynthetic intensity of persimmon increased with the increase of light intensity. This experiment studied the effect of relative light intensity on the vegetative growth and flowering of durian persimmon. The results showed that with the relative light intensity weakened in the canopy, the branch number, fruiting branch rate, branch vigor, leaf development status and flowering rate decreased accordingly. In order to improve the branch quantity, flowering rate and fruit setting rate, the current tree structure of Qiaohua large crowns should be dealt with and the number of branches, canopy thickness and canopy shape should be adjusted and reformed.
