| 摘 要： | 对枣树不同器官抗风力的年变化和日变化及影响枣树抗风力的因素进行了研究。结果表明，在一年中以休眠期抗风力最强，依次为果实生长期、花期，果实着色成熟期抗风力最弱（风速１５～２０ｍ·ｓ－１，持续８ｍｉｎ，落果率达到２０％～３０％）；在一天中，以凌晨至日出前抗风力最弱，中午前后最强；在各器官中以枣吊抗风力最强，依次为叶片、幼果、鲜花、成熟果实和发育不良的花果；枣树抗风能力还受品种、树龄、整形方式、栽植密度、结实量以及地理环境等的影响。在整个生长季，４级（６ｍ·ｓ－１）以下的风对枣树各个器官都是安全的

| Abstract: | Annual and daily variations of wind resistance and the factors that affect wind resistance were studied on Chinese juiube (Ziziphus jujuba Mill.) . The results showed that within a yearcycle ,the resistance to wind of Chinese jujube was highest in dnrmant period , followed by the phase of fruit growth of blooming , and fruit maturation ; During a day , wind resistance of the tree was highest at noon and lowest at sunrise. Among vari- ous organs , the order of wind-resistance is as follows , branchlet , leaf , young fruit , fluwer , mature fruit , and abortive flower and fruit. The wind-resistance uf Chinese jujube was also depends on cultivar , age , type of trim ,density of plantation ,fruit capacity , and geographical environment. Wind speed less than 6m . s-1 is not harmful to all the organs of Chinese jujube during growing season. |
