幼龄果树(1～5年生)的枝条停止生长晚,根系发育不良,分布较浅,因而越冬性能不强常发生枝条脱水、皱缩、干枯等抽条现象。轻者造成树形紊乱,妨碍早日形成树冠和早期结果,重者会使全部枝条枯死。冬季防寒是防止幼树抽条的一种重要技术措施,但防寒方法要得当,才会收到满意的效果。
Young fruit trees (1 to 5 years old) to stop the growth of late branches, root system dysplasia, the distribution is shallow, so winter performance is not often occur branches dehydration, shrinkage, dry and other pumping phenomenon. Light caused by tree disorder, impede the early formation of crown and early results, severe cases will make all the branches dead. Winter cold is to prevent sapling an important technical measure, but the cold method should be properly, will receive satisfactory results.
