| 摘 要： | 研究不同沼肥施用方式下的枣树长势与产量变化,结果表明:在年生长周期内枣树枝干生理生长在夏季最快,基径、树高、梢粗和梢长的增长量最大;枣树叶片的生理生长在春季最快,叶片厚度、叶绿素含量及叶面积指数增长量最大;沼液根施促进枣树基径生长发育,沼液喷施促进树体高度、梢条和叶片的生长发育,同时明显提高了叶片中叶绿素含量和叶面积指数;沼液喷施可提高枣树果实的单果重和产量,并在一定程度上改善果形指数;沼肥应用效果以沼液喷施为最佳。

| Abstract: | Growth and the yield of Zizyphus Jujube under different application ways of biogas fertilizer(root-fertilizing,spraying,smearing,dropping)were studied.The results showed that the tree branche grew fastest in summer,and the basal diameter,tree height,shoot diameter and shoot length had the biggest growth.The leaves of Zizyphus Jujube tree grew fastest in spring,and the leaf thickness,Chl content and LAI had the largest growth.Root-fertilizing could promote the growth and development of basal diameter.Spraying could promote the growth and development of tree height,shoot and leaf,and also increase the Chl content and LAI.And so it was found that spraying was the best way of biogas slurry application,which increased the single fruit weight and yield,and improved the fruit shape index. |
