Trunk spiral girdling of litchi must assembled with the corresponding management. Strong and vigorous young plant should be chosen to carry out trunk spiral girdling. And the fertilization should be enhanced, especially organic fertilizer, watering during the florescence and fruit setting. Young leaves should be extirpated on time, fertilized 4 times by spraying on leaf during flowering and fruit setting.
What corresponding technology for spiral girdling should be adopted for the future? Whether the spiral girdling can make high yield in consecutive year? These were need further research and the improved technical measures.
