| 摘 要： | 果园土壤中的水分直接影响着果树的生长发育。试验表明 :覆草、覆膜效果明显好于清耕。果园覆盖后大大减少了土壤水分的蒸发 ,其土壤含水量分别比对照提高 2 3 44 %、 18 39%。覆草、覆膜后 ,苹果树的根系活力、叶片相对含水量、新梢长度、叶面积大小、叶绿素含量均高于对照 ,硝酸还原酶活性、光合强度比对照有明显提高 ,细胞质膜相对透性明显降低 |

| Abstract: | The study of effects of ground cover and Plastic Mulching on growth and development of young apple trees on dry soil showed that the soil water content improved 23 44% and 18 39%.The root activity,leaf relative water content,the shoot length,leaf area,the content of chlorophyll,the nitrate reductase activity,photosynthetic rate all increased significantly.The membrane permeability decreased. |
| Keywords: | Ground cover Plastic mulchin Dry soil Young apple tree |
