大龄小樱桃树要改接大樱桃,由于适宜嫁接部位的砧桩太粗(直径在10cm以上),无法采用劈接、插皮接等传统接法。经过试验,可用原树抹头后的萌蘖带木质部芽接法进行改接。 1.抹头 3月中、下旬将小樱桃树下部各骨干枝留30cm左右抹头;为了不影响当年收入,也可在小樱桃果下树后(5月下旬)抹头。 2.肥水管理 抹头后及时追施适量速效氮肥及有机肥,并随即浇水。由于小樱桃树的隐芽寿命长,受到全树抹头的刺激,不久,锯口下便会萌发出很多萌蘖,这
Older cherry trees to be replaced by large cherry, due to the appropriate grafting site of the anvil pile is too thick (diameter of 10cm or more), can not use split, plug the skin and other traditional access method. After testing, the original tree head after the sprouting with the Ministry of xylem budding method to change the connection. 1. The first 3 months of mid-to late, the small branches of the lower part of the cherry tree stay around 30cm head; in order not to affect the income of the year, but also in the cherry tree under the tree (late May) wipe head. 2. Fertilizer and water management timely after the first topdressing effective nitrogen and organic fertilizer, and then watering. Because of the long cherry bud life, by the whole tree head to stimulate, and soon, saw under the mouth will sprout a lot of sprout, which
