柴达木地区枸杞硬枝扦插育苗试验研究

Research on Hardwood Cutting and Seedling Cultivation of Lycium barbarum in Qaidam Area

摘要: 通过柴达木地区枸杞硬枝扦插育苗过程中插穗保鲜与贮藏、插穗储藏期间防霉变腐烂、插穗愈伤组织诱导、扦插时间、插穗放置对插穗处理效果影响和高床和平床扦插对比试验研究。结果表明，在规模化硬枝扦插育苗生产中，采取窖藏的处理方式；药剂处理随着处理浓度递增，霉变腐烂率降低；水分处理对插穗的霉变腐烂率影响更大，储藏期间，10 d洒水1次，每次2 L³/m²，并采用1000 mg/kg多菌灵液处理后效果最好；硬枝扦插适宜在5月中旬进行；倒置处理对插穗愈伤组织生物量和扦插成活率具有显著的促进作用；采用高床，有利于愈伤组织的分化和根源基的形成，使插穗尽快生根，提高成活率。

Abstract: The effects of cuttings preservation and storage, decay prevention, callus induction, season, cuttings placement and bed type, on cuttings treatment were studied. The results showed that cellaring was used in the large-scale of hardwood cuttings production. With the increasing of the concentration, the rotting rate was decreased. Water treatment has a greater impact on the decay rate of cuttings. During storage, water was sprayed once every 10 days, 2 L³/m² each time, and the treatment with 1000 mg/kg carbendazol solution had the best effect. Hardwood cutting is suitable to be carried out in the middle of May. The inverted treatment can significantly promote the biomass and survival rate of cuttings callus. The use of high bed is conducive to the differentiation of callus and the formation of root group, and improving the survival rate.
