2. Choose a suitable rootstock, preferably with a very smooth appearance. Cut a knife horizontally at a certain distance from the ground, the depth is not much, about 1.5cm, and then pry open the leather surface.
3. Insert the Scion into it. In order to improve the possibility of survival, the two should be closely combined and tied tightly with plastic bags or wide ropes. When they grow together, they can be removed.

cultivation techniques
Field planting
Choose sandy loam with deep soil layer and good drainage to avoid low-lying and waterlogged areas. The row spacing between plants is 1.5m× 4m, north-south direction. Planting hole depth1m×1m× 0.8m. Applying decomposed organic fertilizer to each hole is about 10 kg. When planting, the seedlings are planted at the same level. Put the seedlings into the hole, and when the soil is buried to 1/3, lift the seedlings upward, so that the roots can be fully stretched, and then add soil to be practical. After planting, water is poured into the tree hole, and then dried at the height of 50- 1500px, and 4-6 full buds are left after cutting. Fast-growing seedlings planted in winter must be ridged for cold protection in winter, and the ridging height is 40- 1250px.
Abundant water
When the new shoots grow to about 15 cm, apply quick-acting fertilizer, and alternately apply underground topdressing and foliar spraying. From the end of September to the beginning of 10, organic fertilizer and compound fertilizer were applied. After the shed is closed, urea is applied before germination, potassium sulfate compound fertilizer is applied after flowering to the fruit expansion stage, and urea and potassium dihydrogen phosphate 10- 15 days are sprayed, which can simultaneously spray 500 times of bacterial liquid. Water the seedlings once after planting, and then determine the amount and time of watering according to the specific situation.
