目前在板栗生产上采用较多的嫁接方法有插皮接、切接和劈接等,这些嫁接法尚存在成活率不够稳定、嫁接速度较慢和接穗用量较大等不足。我们自1990年以来,尝试了板栗单芽切接技术,三年共嫁接实生幼树20942株,成活19353株,平均成活率达92.4%(见下表)。 具体方法是:清明前后(平均气 At present, more grafting methods are used in chestnut production, such as plugging, splitting and splitting. These grafting methods still have some problems, such as the survival rate is not stable enough, the grafting speed is slow, and the amount of scion is large. Since 1990, we have tried the chestnut single-splicing technique, and in 20 years we have 20,942 saplings and 19,353 surviving plants with an average survival rate of 92.4% (see table below). The specific method is: clear before and after (average gas
