【摘要】 对甜樱桃大紫应用环剥技术，能显著增大果个，提高可溶性固形物含量，提早上色，并能提高座果率，其中以花后１周处理最好。环剥对叶片会产生一定不良影响，但并不影响翌年梢叶生长及座果，还会促进花芽的形成。环剥后有极微量流胶现象，不影响伤口愈合，２ａ的试验说明，环剥后２０ｄ内伤口可完全愈合。环剥加喷尿素或高美施等比单剥在促进座果和提早上色方面效果更加显著，对叶片发育亦具良好影响。更多还原

【Abstract】 Girdlingon sweet cherry‘Black Tartarian’could increase significantly fruit size and sol-uble solid content,improve fruit set mumbers and advance fruit color.Girdling should bemade after full bloom,about a week later, Although girdling hassome certain bad effects onthe leaves,it would not have bad effects on the growth of shoot and leaves as well fls fruitsetthe next year,in turn it could enhance the fllower bud formation,There is a trace of qummo-sis without affecting wound healing, A complete callus was formed in 20 days after girdlingduring two-year experiments. Girdling in conibination with spraying urea or‘Gao Mei Shi’could more remarkablely improve fruit set and color than girdling alone。The former methodalso henefits the chetrry leaves。更多还原
