我在去年和今年两次将西红柿和土豆嫁接成功,一棵植物地面上的茎结西红柿,地下面的茎结出土豆,长得很有趣。去年六月上旬,我将土豆幼苗当砧木,当土豆长出五六个片叶子时,在离地面5—10厘米处用刀割断,再在横切面的中央竖切一刀,切口大约3厘米深,然后把长着两三片叶的西红柿幼苗切一段,作为接穗,把大叶去掉,只留小穗,再把下端削成楔形双斜面,斜面的长度和砧木切口的深度相等。把接穗插入砧木的切口,最后用麻绳扎紧。1983 I succeeded in grafting tomatoes and potatoes twice last year and this year, stalks of tomatoes on the ground of a plant, potatoes on the stalks on the ground, and it was very interesting. In early June last year, I planted potato seedlings as rootstocks. When the potatoes grew five or six leaves, they were cut at a distance of 5-10 cm from the ground and then vertically cut at the center of the cross section. The incision was about 3 cm deep , And then cut two or three leaves of tomato seedlings cut, as a scion, remove the big leaves, leaving only the spikelets, and then cut the bottom of the wedge-shaped double bevel, the length of the incline equal to the depth of the rootstock incision. Insert the scion into the rootstock’s incision and tie it up with the hemp rope. 1983
