【摘要】 对７年生乔化苹果内膛光照变化及其影响因素的研究结果表明，内膛光照随距树冠顶点或外围距离的增加而减小，基部与中心干处最低，适当提高上层骨干枝枝型指数，对改善内膛光照具有重要意义。更多还原

【Abstract】 The investigation of in terior canopy light regimes and the influencingfactors within the apple trees of 7 year old standard size showed that the light exposureof interiior canopies decreased with the increment of folliage depth from top or exteriorcanopy,and that the bottom and the around central leader canopy positions were lowestin light expostire.A proper increase in upper scaffold branch index had great importancein interior canopy light improvement.更多还原
