1. Young tree stage: For young trees with weak growth, cut short, cut off too dense branches and too thin branches, and keep strong branches. Pruning can reduce nutrient consumption, promote nutrient accumulation and ensure later growth.

2. Fruit expansion period: Pruning in this period is mainly to improve the fruit setting rate, and new shoots need to be picked many times to improve the light transmittance.

3. Full-fruiting period: Pruning should be carried out according to the specific conditions of branches in full-fruiting period, so as to ensure that strong branches, weak branches and lateral branches retract at this position, restore growth stones, promote them to produce strong branches, and achieve the purpose of increasing production.

4. Aging period: Pruning is mainly to leave strong branches, trim side buds, and carry out plastic pruning in winter.

Breeding method:

1. Daylighting: you can receive light for a long time and need shading in summer. Don't leave it in the dark for a long time, otherwise it will affect its growth, and the plant will grow excessively, which will affect its normal growth and fruit.

2, moisture: it needs proper watering, it is drought-tolerant, but it must also maintain a certain humidity, otherwise its growth will be affected and flower buds will not differentiate normally. Especially when the growth is vigorous, we should pay more attention to watering and water control, otherwise the leaves will fall off, and in severe cases the plants will not grow normally or even die.

3, temperature: it is relatively high temperature resistant, it should be noted that in the process of its growth, it is relatively necessary to maintain a high temperature, otherwise it will lead to frostbite and can not grow normally.

4. Soil: It can also grow on general soil, and it can still grow on some land with high altitude or poor soil. Usually, the most suitable soil is fertile and breathable soil, and the best drainage performance should be ensured.
