中华猕猴桃原产我国长江流域的森林峡谷地带,在其系统发育过程中形成了喜阴湿怕高温干旱的特性。若在夏季炎热地区进行人工栽培,往往明显地表现出生态环境的不适应。尤其是在我省武汉地区,夏季极端高温可达40℃以上,且持续期较长,一旦管理失当常使猕猴桃幼苗生长缓慢,叶片蕉枯,死苗率高,大苗若不精心排灌也很易整株枯死,给生产栽培带来很大困难。在育苗或栽培管理中,为安全越夏,幼苗期往往要搭设阴棚,一天之内
Chinese kiwifruit originated in China’s forest valley area of the Yangtze River valley, formed in the process of its phylogeny Xianyin wet afraid of high temperature and drought characteristics. If cultivated in hot summer areas, it is often obvious that the ecological environment is not suitable. Especially in the province of Wuhan in our province, the summer extreme high temperature up to 40 ℃ or more, and the longer duration, once the management of kiwi seedlings often make slow growth, leaf banana, dead seedling rate is high, if the seedlings are not careful irrigation and drainage is also very easy The whole plant died, bringing great difficulties to production and cultivation. In the nursery or cultivation management, for the safety of summer, young seedlings often have to build shelter, within a day
