Huang Qiuying's breeding methods and precautions

1. Maintenance methods

1. Temperature: The latitudes of the areas where it is distributed are relatively low, so warmth is more suitable for it. Generally speaking, the range of 20 to 30 degrees is better. In addition, its adaptability is not very good because it is afraid of both cold and heat. Therefore, whether it is winter or summer, adjustments must be made.

2. Light: Huang Qiuying likes an environment with plenty of sunlight and is not shade-tolerant. Whether it is growing or blooming, it cannot be separated from light. If it is kept in a dark place for a long time, its flowering may be affected. In addition, it also needs to be placed in a well-lit location in winter.

3. Watering: The waterlogging resistance of Huang Qiuying is very poor, so water cannot accumulate. During the growth period, it requires relatively more water, but not too much. When the rainfall is very heavy, it must be drained in time.

4. Fertilization: Huang Qiuying is relatively resistant to barrenness and does not require too much fertilizer. You can choose soil with sufficient nutrients, and then there is basically no need for top dressing.

2. Breeding techniques

1. Reproduction: In addition to sowing, the commonly used method is cutting. Early summer is the best time for breeding. It is better to choose young branches, as the chance of success as cuttings is higher. After inserting into the substrate, if the surrounding environment is kept suitable, it will take root in about fifteen to twenty days.

2. Pruning: This is a relatively important step. First of all, in spring, a relatively important task is pinching. However, if it is a seedling, it needs to be topped when four to five true leaves grow. Then there is the pruning of branches and leaves. The old ones can be cut off directly, and the dense ones can be partially cut off.

3. Problem diagnosis and treatment

1. Diseases: There are two common diseases, one is "powdery mildew" and the other is "leaf spot", which are relatively common in summer. It can be controlled by drugs such as mancozeb, and supplemented by measures such as pruning.

2. Pests: There are two common types of pests, one is "aphids" and the other is "beetles", which can be prevented and controlled with insecticide.
