1. Soil management: it is suitable for a wide range of soil selection. Generally, sandy soil is used for planting. The one with good drainage and high nutrient is more suitable for the growth of Erythrina.
2. Water management: Erythrina cristata can grow in dry and barren places and can resist salt and alkali. However, when it is watering, it is not allowed to accumulate water. Too much water will lead to root rot 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 nutrient absorption of Erythrina, and is more conducive to its growth.
4. Light and temperature management: it has good adaptability, likes the environment with high light and temperature, and has strong cold resistance. It is most suitable to be raised in the place with good outdoor light. The whole day and half sunshine can be used for the exposure time.
1. Pruning: when the branches are yellow and withered, prune them in time, and dispose and bury the pruned branches in time, so as to avoid the influence of pathogens and pests in the branches on the growth of their rhizomes.
2. Cuttage: generally, cuttage is used for propagation, and robust branches are selected, about 20 to 40 cm, which can germinate in about two days in the moist soil with nutrients, and can be transplanted in about 30 to 60 days after cultivation.
1. Rotten skin disease: it is very easy to die after the rotten skin disease of the crow. At first, it will show external rotten symptoms, and then it will grow slowly. At this time, it is necessary to cut off the rotten branches in time and spray pesticide to wrap them.
2. Leaf spot disease: the leaf spot disease mainly appears on the branches and leaves, and there will be gray black symptoms in the diseased area. At this time, you should use the emulsion of Difenoconazole to dilute it with water, and spray on the branches of Erythrina.
1. How to get into the winter: when it's winter, it should be transplanted to the indoor for cultivation. The temperature should be above 4C. It's best to place it in a place with good scenery. In winter, you don't need to water too much, just keep the soil moist.
2. Whether it can get wet or not: in rainy days, Erythrina cockscomb should be drained and drained in time. It is not allowed to have accumulated water for storage. If there is accumulated water, it will lead to root ulceration.
