一、延迟冬季修剪,做好伤口保护分清、区别冻伤芽和冻伤枝,最大限度地保证产量和树体长势。在低温过后修剪,要减少伤口,并要及时用剪口油进行伤口保护;对已经修剪的苹果树的剪锯口,没有保护的,要用剪口油保护。对腐烂病疤,于春秋两季涂抹防治腐烂病的相关药剂(3%甲基硫菌灵、果康宝、金力士、腐烂立克、施纳宁等)。同时,萌芽后,要检查缩剪冻死枝条,严防冻害后苹果腐烂病的爆发和流行。
First, postpone the winter pruning, do a good job of wound protection, the distinction between frostbite buds and frozen branches, to maximize the yield and tree growth. Pruning after the cold, to reduce the wound, and to promptly cut the oil for wound protection; cut the apple tree has been pruned, no protection, use scissors oil protection. On the decay of the scar, in the spring and autumn smear decay disease related agents (3% thiophanate-methyl, combo, Golden Guinness, rotten Rick, Schnauzer, etc.).
