摘要： 后屋面散射光(包括一部分直射光)对黄瓜生长有很大的影响.与对照相比,处理平均单株叶面积增加8.07%,叶面积系数增加7.81%,叶绿素a+b增加15.54%;定植后70天株高、茎粗和展开叶片数与对照差异极显著;定植后两个月的根、茎、叶干重分别增加36.89%、46.37%和50.00%,产量提高21.16%.

Abstract: Scattered light from the back-roof of lean-to house(containing a part of battle-sight light) was of great influence to growth and development of cucumber growing in lean-to house, As compared with contrast,the average leaf area of single plant was increased by 8,07%，the indix of leaf aera was increased by 7,81%.Chl, a+b was increased by 15.52%.The differences of seedling height,stem thickness and numbers of spreading leaves of cucumber were prominent or extremely prominent 70 days after transplant,Dry-matter of root, stcm and leaf were increased by 36,8900，46, 37%，and 50,0000，respectively, Fruit yield of cucumber was 21.160% higher than that of contrast,
