杏树设施栽培克服了晚霜低温伤害和花芽冻害,延长了鲜果供应期,但凯特杏幼树营养生长旺盛,长中枝比例高,限制了以短果枝及花束状果枝结果为主的凯特杏的早期产量。环剥可以控制营养生长,促进结果,提高果品质量。笔者选择玉田县谢甲庄村日光温室凯特杏园内,对株行距1×1.5米的3年生凯特吉进行环剥试验。果实采收后,在距地面20～30厘米主干光滑处环剥,剥口宽度0.3～0.5厘米,剥后用25%多菌灵100倍液涂抹伤口消毒,并用纸条或薄膜密封。结果显示,环剥可有效优化凯特杏幼树枝类组成,增加短枝及花束状枝比例,改善养分的合理分配,降低枝条平均生长量,增加花束状枝、
Apricot tree cultivation overcomes the low temperature injury and flower bud frost damage, prolonging the supply period of fresh fruit, but the vigorous vegetative growth of Kite apricot saplings and the high proportion of long middle shoots restrict the development of kite apricot Early production. Girdling can control vegetative growth, promote results and improve fruit quality. The author chooses Shetian County Xiejia Zhuang Village sunlight greenhouse Kate apricot garden, the row spacing of 1 × 1.5 meters 3-year Katie guitar ring test. After harvesting the fruit, the skin should be stripped at a thickness of 20-30 cm from the ground and stripped to a width of 0.3-0.5 cm. After stripping, the wound should be disinfected with 25% carbendazim 100 times and sealed with strips of paper or film. The results showed that girdling could effectively optimize the composition of young branches of Kite apricot, increase the proportion of shoots and bouquets, improve the rational distribution of nutrients, reduce the average growth of shoots,
