Substrate: Choose fertile loam with good air permeability and water retention capacity and a humus content of more than 3%, and apply an appropriate amount of bone meal as base fertilizer. Light: An environment with sufficient lighting is suitable. Nutrients: During the sapling stage, thin fertilizers should be applied frequently, mainly organic nitrogen fertilizers. Temperature: It has strong cold resistance. If the temperature is low in winter, warmth and anti-freezing measures need to be taken.

2. Breeding skills

1. Maintenance method

1. Substrate selection: Its root system is relatively developed and its soil requirements are relatively high. The soil needs to be fertile and have good air permeability and water retention capabilities, and is not prone to water accumulation. After waterlogging, the humus content needs to reach more than 3%. An appropriate amount of bone meal can be applied as a base fertilizer before planting to facilitate its vigorous growth.

2. Light management: It prefers light and is best cultivated In an environment with sufficient light, if it is planted indoors with bright light, it may only bloom but not bear fruit.

3. Nutrient management: saplings before they bear fruit At this stage, the plant's root system is shallow and its ability to absorb nutrients is not strong. Therefore, water and fertilizer management should be strengthened at this time and thin fertilizer should be applied frequently. Spring shoot fertilizer in March, summer shoot fertilizer in May and winter fertilizer in November are essential every year. It is best to use organic nitrogen fertilizer as the main fertilizer, which can promote its vigorous growth and flowering and fruiting.

4. Temperature management: It is relatively cold-resistant. The average temperature in the production area is 17.5°C. If the ambient temperature is low in winter, you need to take measures to keep warm and cold-proof to help it survive the winter safely.

2. Breeding skills

1 . Propagation method: It can be propagated by sowing or grafting. The grafting method is the main method, and it is best to do it between March and June every year. After grafting, the soil should be kept moist as much as possible, and the scion can take out new leaves. Carry out top dressing.

2. Pruning method: Its pruning can keep the leaves as much as possible , the number should be properly controlled after flowering, and deformed or overly dense flowers should be cut off in time to promote plant fruiting.

3. Problem diagnosis and treatment

1 2. Spots: Bacteria can easily cause canker disease, causing the surface of the plant to be rough, producing canker spots with a diameter of about three to five millimeters. Once discovered, the diseased branches and leaves should be cut off in time, the diseased fruits should be cleaned and burned on the spot, and at the same time, spray properly according to the instructions. Lime sulfur mixture eliminates the source of the disease.

2. Pests: The more common pests include malignant leaves Insects, spider mites, leaf miners, etc. harm the leaves. Attention should be paid to prevention and control during the shoot-out period, and insecticides should be sprayed in a timely manner.

IV. Other questions

1 . Placement: It prefers light and is best grown in an open-air environment with full sunlight. If placed indoors, it may only bloom and not bear fruit.

2. Toxicity: It is not toxic, and its peel and leaves Both can be used as medicine, and can also be used to prepare aromatic essential oils, with high practical value.
