摘要
为探讨平欧杂种榛低产园改造技术,采用劈接的方法进行品种改良试验,结果表明,嫁接高度为40～50 cm时,各品种(系)嫁接成活率最高;1-21(品系)、辽榛3号在嫁接后的生长量、抗寒性、果实产量等综合性状超过其他品种(系),可以作为低产榛园嫁接改优的最佳品种(系);嫁接后结果第2年应该加强树体的水肥管理,提高树势。
To discuss the technique for transformation of low yield orchard of Ping’ou hybrid hazelnut,cleft grafting were used in experiment.Result indicated that:when grafting at 40~50 cm above ground,the survival rate was the highest.Comprehensive characteristics such as growth,cold resistance,nut yield of strain“1-21”and“Liaozhen No.3”were better than the other strains,which could be taken as the best varieties for improving low-yield hazelnut orchard.In the second bearing year of grafted orchard,water and fertilizer management should be strengthened to improve the tree vigor.
