Soil: Planting rowan requires relatively fertile soil; Watering: If it is not a drought, plants grown in the open field generally do not need watering. In dry weather, they need to be watered once a week; Fertilization: Two top-dressing fertilizers are required during the growth period. To three times, apply less fertilizer each time and more frequently. Lighting: It cannot accept exposure to the sun. When it is illuminated, it is dominated by astigmatism. The lighting time every day should be four or five hours.

1. Maintenance methods

1. Soil: It absorbs nutrients relatively quickly, so try to use fertile soil to cultivate it. Before planting, the soil needs to be mixed with base fertilizer. The base fertilizer can be fertilizer cake or farmyard manure.

2. Watering: Moisture conditions are particularly important for the growth of plants. If the seedlings are sown in autumn, if it does not rain by April of the next year, the soil will be dry and peeling, and it needs to be watered. It is watered manually, and the watering frequency is once a week. If it is a plant maintained at home, it also needs to be watered once a week.

3. Fertilization: Fertilization should be done in small amounts and often times. "Principle of fertilization. During the growth period, you need to fertilize once a month. Use urea or diammonium phosphate as fertilizer. Fertilizer should be applied after rain, or after irrigation. After August, fertilize Potassium dihydrogen phosphate solution is sprayed, usually once every ten days, and sprayed twice. The purpose is to promote the lignification of the plants, which can increase the overwintering ability of the plants.

4. Lighting: It does not like sunshine and prefers shade, and cannot accept sunlight exposure. When it is exposed to sunlight, it must be given astigmatism. When planted in the open field, it must be maintained on the shaded side of the backlight.

2. Breeding skills

1 , Reproduction: Reproduction It can be reproduced by sowing seeds. Treat the seeds with cold and wet conditions, because the seeds will stop germinating when the temperature exceeds five degrees. Therefore, it is best to start treating the seeds four months before sowing. Soak the seeds in water at 40 degrees for one day, and then use high manganese Sterilize with potassium acid, clean it, then mix it with sand in a ratio of 1:3 and place it at a temperature below 5 degrees. Turn it frequently and it will germinate in about 70 days. After germination, you can sow the seeds, just sow the germinated seeds into the soil.

2. Pruning: As it grows, branches and leaves will rot. Just cut off the problematic branches.

3. Problem diagnosis

1 . Insect pests: Spider mites, also known as red spider mites, are a type of insect pest that plants are more susceptible to. Spider mites will suck sap on the back of the plant leaves, causing small white spots on the plant leaves. In severe cases, they will fall off. If found, it needs to be sprayed with dimethoate emulsion diluent.

2. Lesions: White silkworm will harm the base of the plant, causing it to rot. After the plant is infected, carbendazim wettable powder needs to be sprayed.

IV. Other questions
