摘要
在干旱坡地条件下栽培梨树,应用生长调节剂CCC和MH及其不同组合进行喷雾处理,结果显示CCC和MH能提高叶片中主要营养元素和叶绿素的含量,增加吸收小根量,促进梨树旱生结构的发育,减少叶片水分亏缺,增加树冠短果枝数量,使树体变紧凑,促进当年花芽分化,提高坐果率,增加单位面积产量。根据试验指标综合分析,用CCC喷布2次和用CCC+MH混合喷布2次,效果最佳。
With the spraying treatment of the growth regulators such as CCC and MH on pears in dry slope land,the content of the main nutritional elements and chlorophyll in leaves could be increased,the number of absorption rootlets could be raised,the development of xeromorphism could be promoted,water shortage in leaves could be decreased,number of leaves and crown short branches could be increased,trees could become compact,flower bud differentiation could be promoted,percentage of fertile fruit could be increased,and the yield per unit area could be increased.In accordance with comprehensive analysis of index,the best results could be achieved by spraying with CCC and CCC＋MH twice separately.
