Definitions
- the invention relates to the field of citrus seed industry, in particular to a method for planting large citrus seedlings in disease-free containers with rapid high yield and strong disease resistance.
- the existing citrus planting methods mostly use bare root seedlings to dig small holes for planting. This method digs out the main roots and loses a large number of fibrous roots. When planting, pruning branches will lose a large amount of original growth, and it is easy to die. After a slow seedling period of 2-3 months; at the same time, the seedlings are small, and there are many wounds caused by cutting roots and pruning branches during planting. They are susceptible to diseases and have very weak resistance to diseases and insect pests. They require longer and more detailed management, generally 4 years. High yield and cost recovery.
