1、 Curing method

1. Soil: there are no requirements for soil quality. Soap pods can be planted in general soil. It is OK to choose sandy loam for self planting. It is fertile, breathable and has good drainage performance, which is very suitable for its growth

2. Water: Gleditsia sinensis has strong drought resistance, because its roots will grow very deep and can store water by themselves. The usual watering time is about 30 days. The amount of water is subject to thorough watering, but do not store ponding

3. Nutrient: scientific fertilization is very important. It is best to choose the rotten and fermented cow and horse manure during growth. The fertilizer should be spread evenly, so that the soap pods can be fully absorbed

4. Light: Gleditsia sinensis has a certain shade resistance. It is a light loving plant, which is suitable for sufficient sunlight, but does not like strong direct light. Strong direct light will cause sunburn of its branches and leaves

2、 Breeding skills

1. Pruning: after planting, pruning should be strengthened to cultivate the growth of the trunk. When pruning, it should focus on the height of the trunk and the roundness of the crown. Some withered branches and buds should also be pruned, so as to promote the growth of side branches and the roundness of the crown

2. Propagation: it is usually carried out by sowing and propagation. Old trees aged between 30 and 80 years are selected to produce full seeds. Dry it in the sun, then beat it to remove the peel and soak it in water for two days and two nights. Then take it out and put it in wet sand for germination and storage. When the seeds crack and expose diphtheria in mid March, they can be planted

3、 Diagnosis and treatment problems

1. Coal pollution disease: if the branches of the tree crown are too dense and the interior is not ventilated and transparent, it will be infected with coal pollution disease. At this time, the branches and leaves should be sprayed with diluted haolik to control the spread of the disease. It can be solved by spraying once a week or about three times

2. Saponification Psylla: the common pest is saponification Psylla, which is very harmful to it. It can be prevented and controlled by spraying diluted with hypertonic phenoxymethyl EC

4、 Other issues

1. How to spend the winter: before winter comes, it should be watered with winter water, so that it can be protected from freezing damage in cold winter. Wait until early spring to pour thawing water again, so as to promote the emergence of new branches and buds

2. Whether it can rain: it can rain, but it should be drained and waterlogged in time after the rain to avoid affecting its normal growth
