1、 Curing method

1. Temperature: Acer grandiflorum likes a warm growth environment. It can resist a certain low temperature. In winter, as long as the temperature is kept between zero and five degrees, it can survive the winter normally. However, if you plant in the north, you need to keep warm. You'd better not choose to spend the winter outdoors, otherwise there will be frostbite

2. Watering: it is enough to keep the soil moist during the growth of Acer henryi. The watering should be thorough and there should be no ponding. In the seedling stage, the demand for water is not very large. With the growth of plants, the demand for water will increase, so watering needs to be determined by observing the growth of plants

3. Light: Acer henryi is a semi shade plant and cannot be directly exposed to strong light. The branches and leaves of the plant will be scorched after being exposed to strong light. So it can be transplanted to a shady place or shaded in summer. Just accept warm oblique light during growth

4. Fertilization: we should pay attention not to apply partial nitrogen fertilizer. We can apply thin fertilizer and water in spring, and focus on phosphorus and potassium fertilizer during growth. Such reasonable fertilization will make the branches and leaves more colorful and have higher ornamental value

2、 Breeding skills

1. Propagation: cutting and sowing are two important propagation methods. When cutting, cut the twigs into small segments of about 10 cm, and then replant them. The most suitable temperature is about 27 degrees. The seeds of Acer henryi are harvested in autumn. The best time for sowing is in spring. The depth of seeds buried in the soil should be about two centimeters, and then cover it with some straw and wait for germination

2. Pruning: Acer henryi, as an ornamental plant, needs to be pruned reasonably in order to ensure normal viewing. Pay attention to the sense of hierarchy, pay attention to the growth in daily life, and cut off some side branches with poor growth

3、 Problem diagnosis and treatment

1. Disease: leaf blight will occur. This disease will seriously affect the viewing. It starts to dry on the edge of the branches and leaves, and finally the branches and leaves of the positive plant wither. The diseased branches and leaves can be cut off in advance, or drugs can be used to prevent it

2. Insect pests: beetles occur, mostly in summer, and can be sprayed with trichlorfon solution for control

4、 Other issues

1. Toxicity: it has no poison and can reduce swelling. Don't worry about poisoning

2. Whether it can be raised at home: not suitable. It is mostly planted in gardens to beautify the environment
