Cutting time

The cutting time should be from mid May to mid July and from mid September to mid October every year. At this time, the new shoots have stopped growing, the branches have more nutrients, the meristem ability is strong, and the temperature is appropriate, so it is easy to take root

Matrix preparation

The slightly acidic sandy loam with deep soil layer, loose and fertile soil and good drainage is the most suitable

Cuttings selection

Take the excellent plants with vigorous growth and no diseases and pests as the mother tree. Cut the current year semi lignified twigs on the upper part of the periphery as cuttings. All cuttings were graded and bundled into small handfuls, and the base was wrapped with wet toilet paper and brought back to the room for cutting

Cuttings treatment

Cut each section of cuttings into 8-10cm long, keep 2 leaves on the upper part, cut off half of the leaves, cut the upper end into a flat mouth, and cut the base into an oblique mouth, then immerse 3cm of the base in 5 / 100000 NAA or 1 / 10000 ABT rooting powder solution, and take it out after 1 hour

Cutting operation

Cuttings shall be cut in bed (section) according to the diameter grade. With 5 × Insert the tree into the hole of the ear with a spacing of 3 / 3 cm, and then insert it into the hole around the ear with a thick stick. Finally, use 10000 times of carbendazim solution to pour through the slotted bed for soil disinfection and water moisturizing

Post insertion management

① The soil humidity should be about 50%, while the air humidity should be more than 85%

② At the initial stage of cutting, the shade degree of the shade shed is maintained at about 80%, which not only prevents direct sunlight, but also ensures sufficient scattered light, so as to facilitate photosynthesis with leaf cuttings and facilitate rooting

③ After 10 days, the leaves were sprayed with 0.2% potassium dihydrogen phosphate or 0.5% calcium superphosphate and 0.1% urea solution once

④ After 30 days, it basically takes root, the film can be removed and the light can be increased. After the rooting, we should pay attention to the spray and shading of the leaves on sunny days in summer. p>

⑤ In order to make the seedlings grow healthily, 0.05% of "foliar treasure" can be sprayed on the leaves, and do not apply fertilizer from the roots. It can be transplanted in pots from September to October or the next spring
