1、 Grafting

Choose the time when the rootstock grows fastest to graft. The time is about March in spring every day. Generally, 3-year-old seedlings are selected as rootstocks. It is best to cut them 50 cm to 80 cm from the ground and then high grafting, so as to ensure better growth in the year of grafting. After planting, quick acting fertilizer should be applied twice in spring and summer. In summer, the soil should be properly wet, but from autumn, the soil still needs to be dry

2、 Cutting

1. The top bud must be cut off five days before the branch is taken off. When the branches are cut off, the base must be soaked in water immediately. The soaking length needs to be 3 cm. The ear should be cut into 10cm segments, with at least three sections on it. The upper wound should be cut neatly 1.5cm away from the leaf bud, and the lower wound should be 3cm away from the branches. The wound must be smooth. Leave three leaves on each ear and reduce the leaves by half

2. The choice of soil can be river sand or vermiculite, sprayed with potassium permanganate and covered with film for two days before use. The ear strips should be soaked in flowing water for one day and one night, and then soaked in 50 ℃ warm water for 12 hours, and then dried with water

3. When cutting, the row spacing needs to be kept at 5cm × 10cm, vertically inserted into the soil, and then watered thoroughly at one time

4. In the subsequent daily management, attention should be paid to ensure that the temperature is about 28 degrees and the relative humidity needs to be maintained at 85%. Spray water twice a day to ensure that the leaves are fresh and the soil is moist. Urea solution should be applied every half a month to fertilize in the form of spraying

3、 Sowing and propagation

After the seeds are harvested in October every year, they can be sown. After sowing, they need to be covered with two centimeters of soil, watered with water, and covered with a layer of straw. After the seeds germinate and grow into seedlings, remove the straw. The row spacing of sowing is 15 cm to 20 cm, and the amount of sowing per mu of land is 4 to 5 kg. It should be noted that their seedlings cannot withstand the sun, so they must be properly shaded. In addition, when the seedlings grow to a height of 30 cm to 50 cm, they can be transplanted. They must be transplanted with soil, so as to ensure a high survival rate
