不同品种大果沙棘扦插生根能力研究

Rooting Ability of Different Varieties of Hippophae rhamnoides Cutting

在同一扦插基质条件下,采用大田扦插方法,研究10个大果沙棘品种的成活率、发根数、根长度及新梢长。结果表明,插穗的生根能力及后期长势与品种有关,10个引进的大果沙棘品种中,深秋红最佳,扦插成活率、生根率与其他品种差异显著,扦插成活率和发根情况效果最好,契切克品种次之,丘伊斯克品种最差。

Under the same cutting substrate condition, the survival rate, root number, root length and new shoot length of 10 large seabuckthorn varieties were studied by field cutting method. The results showed that the rooting ability and late growth of cuttings were related to the variety. Among the 10 introduced seabuckthorn varieties, the deep autumn red was the best, the survival rate of cuttings and rooting rate were significantly different from other varieties, and the survival rate and rooting condition of cuttings were the most effective. Well, the Chechek breed is second, and the Chuysk breed is the worst.
