摘要
以5年生王林/SH40/八棱海棠为试材,研究白色地膜、黑色地布对树体的冠层环境及叶片净光合速率和果实品质的影响。结果表明:白色地膜明显提高树冠下层和内膛的相对光照强度,而冠层内温、湿度在各处理间差异性不明显;对提高叶片SPAD和净光合速率Pn的效果,白色地膜最好,其次为黑色地布。地膜覆盖对单果质量、可溶性固形物含量提升的效果均以白色地膜为最高,分别为256.15 g、16.93%;白色地膜覆盖处理的果实光洁指数为68.01%,比对照提高了1.01个百分点。综上所述,苹果树盘覆盖白色地膜利于提高冠层光照强度,提高光合能力和果实品质。
The 5-year-old ＇Wanglin＇ /SH40/Malus robusta Rehd. were used to research the effects of white film and black ground cloth on the environment of leaf canopy, net photosynthetic rate and fruit quality of apple tree. The results showed that： white film significantly increased relative light intensity of the lower and the bore of crown, while the canopy temperature and humidity had no significant differences among treatment; The best to improve SPAD and the net photosynthetic rate of leaf was white film, followed by the black ground cloth. Fruit weight and soluble solids content were the highest on the white film treatment, respectively, 256.15 g,16.93%; Fruits smooth index up to 68.01% on white film and compared to the control, treatment increased by 1.01 percent point. In summary, white film mulching on the apple tray will improve the canopy light intensity, the photosynthetic capacity and fruit quality.
