近采收期铺设反光膜，是促进树冠内膛果实着色的有效措施之一，但目前仅限地面平铺，增光强度和范围均有局限性。为增加反射光强度及范围，更有效地促进果实着色，我们改进了反光膜的铺设方法，经试验证明效果明显。１试材与方法试验于１９９８年在沂源县燕崖乡西郑村进行... Laying reflective film in the near-harvested period is one of the effective measures to promote the coloring of the inner canopy of the canopy. However, only the ground tiling, the intensifying intensity and range of the light-harvesting have limitations. In order to increase the intensity and range of the reflected light and promote the coloring of the fruit more effectively, we have improved the laying method of the reflective film, and the results have been proved by experiments. A test material and method test in 1998 in Yiyuan County Yanyang Township Xizheng Village ...
