摘要:
为解决洛南县核桃芽接成活率低的技术问题,进行了6个芽接成活率单因素影响试验,结果为,嫁接后晴2~7 d的嫁接成活率平均为44.7%~95.7%,嫁接后晴7 d者最高,嫁接时应选择嫁接后有6 d以上晴天的时段嫁接; 6月10日到7月10日嫁接成活率都在90%以上,显著高于其他时期,是嫁接最佳时期; 砧木、接穗的不同木质化程度的嫁接成活率分别为56.7%~94.0%和44.7%~95.7%,都是半木质化显著高于木质化和未木质化,芽饱满的接穗嫁接成活率为96.0%,显著高于芽瘦小不饱满的接穗(79.0%),嫁接时应选择半木质化的砧木和芽饱满、半木质化的接穗; 嫁接前和嫁接后应选择 50%甲基托布津、70%甲基硫菌灵、铜大师、中生菌素、72%农用链霉素等药剂,采取预防3次、防治3次(或2次)方式,进行主要病害—黑斑病的防治。
Abstract:
To solve the problem of low survival rate through bud grafting, six single factors were experimented with bud grafting. The result showed that bud survival rate with those grafting after 2 to 7 clear days ranged from 44.7% to 95.7%, highest with 7 clear days, which indicates 6 above clear days to be the best time for grafting. Survival rate with those grafted from 10th June to 10th July reached over 90%, superior to other periods significantly. Varied degrees of lignification of root stock and scions resulted in survival rate ranged from 56.7%~94.0% and 44.7%~95.7%, semi-lignification superior to full lignification or un-lignification. Survival rate with plump buds reached 96.0%, superior to small buds(79.0%), which indicates semi-lignification root stock and scions with plump buds are best choice. Before grafting and after grafting, use of 50%thiophanate methyl, 70% thiophanate-methyl, Zhongshengmycin and 72% streptomycin three times were recommended for control black dot disease.
