核桃幼树是否能安全越冬是决定核桃树一生健壮生长和提前结果的关键。是一项重要的管理措施。特别是新栽的幼树,根吸肥吸水能力低,枝条发育不充实,加之核桃树枝干内部髓心较大,经过冬季严寒和早春温度的骤变以及春风的侵袭,使枝条内部水分大量消耗,造成枝于由上向下逐渐干枯,严重时一直干到地表面,称之为灼条,严重时影响幼树成形和提前结果。
Walnut saplings can be safe for winter is the key to determining the robust growth of walnut trees and early results of life. It is an important management measure. In particular, the newly planted saplings have low absorption of water and low absorption of water and poorly developed shoots. In addition, due to the large inner pith of walnut tree branches, the internal moisture of the branches is greatly consumed after sudden changes in winter frost and early spring temperatures and spring breezes , Causing the branches to gradually dry from top to bottom, in severe cases, all the way to the ground surface, which is called the burning rod, which seriously affects the sapling formation and early result.
