1、 Curing method

1. Soil management: the selection of soil is extensive. Generally, sandy soil is used for planting. The one with good drainage and high nutrients is more suitable for the growth of Erythrina gallinarum

2. Water management: Erythrina cristata can grow in arid and barren places and can resist saline alkali. However, there must be no ponding when watering. Too much ponding will lead to root ulceration and affect its growth

3. Nutrient management: organic fertilizer should be applied before planting, and some urea water should be applied after planting. The time of urea water irrigation is about 30 days, which can promote the absorption of nutrients by Erythrina carinata and is more conducive to its growth needs

4. Light and temperature management: Erythrina carinata has good adaptability, likes the environment with high light and temperature, and has strong cold resistance. It is most suitable to be raised in a place with good outdoor light. The irradiation time can be full-time or half day

2、 Breeding skills

1. Pruning: when the branches are yellow and withered, they should be pruned in time, and the pruned branches should be treated and buried in time to avoid the impact of bacteria and insects in the branches on the growth of their roots and stems

2. Cutting: generally, cutting propagation is adopted, and robust branches, about 20-40 cm, are selected. If they are inserted in moist and nutrient soil, they can germinate in about two days, and they can be transplanted into seedlings in about 30-60 days

3、 Diagnosis and treatment problems

1. Rotten skin disease: Erythrina carinata is easy to die after getting rotten skin disease. At first, it shows external rotten symptoms, and then it will slowly expand and grow. At this time, the rotten branches should be cut off in time and sprayed with pesticides to wrap them

2. Leaf spot disease: leaf spot disease mainly occurs on the branches and leaves, and the diseased part will have gray and black symptoms. At this time, Difenoconazole emulsion should be diluted with water, and the branches of Erythrina cristatus can be sprayed

4、 Other issues

1. How to enter the winter: when entering the winter, it should be transplanted to indoor cultivation. The temperature should be above 4 degrees Celsius. It is best to place it in a place with good scenery. In winter, you don't need to water too much and keep the soil moist

2. Whether it can be exposed to rain: in rainy days, Erythrina carinata should be drained and waterlogged in time. There should be no ponding for storage. Ponding will lead to root ulceration
