甜瓜嫁接生产中的生理障碍与对策建议

Physiological Barrier and Countermeasures in Melon Grafting Production

在我国北方地区寒冷季节保护地甜瓜嫁接生产中,因砧木选用或更换不当而出现生理障碍,造成减产甚至绝收的现象时有发生。根据大量生产实际,分析了甜瓜嫁接生产中不同南瓜砧木与接穗的亲和力以及影响嫁接组合共生亲和力的因素,建议在甜瓜嫁接生产中应首选黑籽南瓜作砧木,对降低生产风险和促进甜瓜嫁接技术的推广具有重要的现实意义。

The irrational use and change of stock always led to physiological barrier, yield reduction, and even no harvest of protectorate melon grafting production in cold season in North China. Based on the production practice, the grafting affinity between different pumpkin stocks and melon, and the influencing factors of affinity were analyzed. Black seed squash should be first selected as the stock, which had important practical significance in reducing the risk of production and promoting the extending of grafting technique.
