1、 Curing method

1. Soil: the soil layer is thick, fertile and conducive to water, which is very suitable for the growth of Robinia pseudoacacia. Before planting, it should be disinfected with medicine or exposed to the sun

2. Water: I like the environment with sufficient water. When pouring water, I should pour it through to make it full of water

3. Nutrients: just use chicken, duck, pig manure and human manure. Lay them flat and dry them, and then sprinkle them evenly in the soil. But don't be too close to the tree root. Being too close will cause burns to the tree root

4. Light: I like light. Robinia pseudoacacia likes mild sunlight very much. Sufficient irradiation will make its branches and leaves green, thick and beautiful. But do not like too strong direct sunlight, which will cause damage to its branches and leaves, and appropriate shading is also necessary

2、 Breeding skills

1. Pruning: during the growth period, it is easy to have dead branches and rotten leaves. At this time, it should be pruned in time to avoid these dead branches and rotten leaves containing bacteria and infecting other healthy branches. Therefore, pruning is also very important

2. Propagation: cutting is often used for propagation. Cut a small section of strong branches and soak them in water to absorb more water. Then cutting to the seedling bed, time in a week or so will see the sprouts grow out. At this time, it should be fertilized, sterilized and protected. When it grows up, it can be transplanted into the soil

3、 Diagnosis and treatment problems

1. Rotten skin disease: the disease of Robinia pseudoacacia is rotten skin disease, and the symptom is the occurrence of disease spots. Then start to distribute the bacteria with small black spots, which is very harmful to Sophora japonica. Some carbendazim should be diluted and sprayed

2. Sophora japonica cocci: this kind of insect pest affects its growth very much. It will suck the juice in the branches and weaken and dry the plants in the long run. To kill insects, use avermectin to dilute it and spray it twice a week

4、 Other issues

1. How to spend the winter: it should be watered once in winter, so as to ensure its water supply throughout the winter and prevent frostbite in the cold

2. Can you get in the rain: Robinia pseudoacacia can get in the rain. When it rains, its branches and leaves will look green and ornamental
