苹果、桃、梨的硬枝露地扦插极难生根成活,因而它们的繁殖至今仍全仰嫁接。近年,国内外在研究苹果、桃的硬枝扦插方面不断有过尝试,其中虽有成功者,但多属采用电热线床土加温,插条激素处理以至人工喷雾等措施而获得。梨的硬枝露地扦插至今未见有成功的报道。作者于1982年春用难生根的‘翠伏梨’枝条为材料,采用长枝深插的方法,在无荫棚、不行床土加温和不用任何激素处理的情况下,成活率达63.3％。 Hard branches of apples, peaches and pears are extremely hard to survive, so their breeding is still grafted. In recent years, at home and abroad in the study of apple, peach hard branch cutting have been tried, although there are successful, but mostly by electric hot wire bed soil heating, plug hormone treatment and artificial spray and other measures obtained. Pear hardwood open cuttings so far no successful reports. In the spring of 1982, “Cuvulin” shoots, which were difficult to root, were used as materials, and the survival rate was 63.3% under the condition of no shade and no soil heat treatment without any hormone treatment.
