| 摘 要： | 旱地果园秸秆覆盖可以使红星、新红星苹果树叶片的单叶面积分别增加９．２９％和１２．１２％，鲜叶比重增加４．０６％和８．２３％，叶绿素含量提高１４．３８％和１６．７２％，叶绿素ａ／ｂ比值提高２．２７％和２．７８％，从而为提高光合速率、促进树体生长发育奠定了基础，使叶片净光合速率分别比对照提高１６．７２％和１８．８２％。

| Abstract: | On arid land orchard,trawmulching enlarged the leaf areas of Starking and Starkrimson apple by9.29%and l2.12%,respectively.The fresh weights per dm2 increased by 4. 06%and 8. 23%, respectively.The contents of chlorophyll increased by l4. 38%and l6. 72%,the ratioes of chlorophyll a to chlorophy b by2. 27%and 2. 78%.This laid a physiological foundation to increase the photosynthetic rate and improve treegrowth and development.As a result,the photosynthetic rates increased by l6. 72%and l8. 82%,respective-ly. |
