Detailed Explanation of Key Cultivation Techniques for Sanhong Honey Pomelo
The orchard can be built in a location with loose, fertile soil and high organic matter content, with good transportation access and convenient drainage and irrigation; the cultivation ratio should be designed from the initial stage of construction. Select pure varieties for scientific planting, and complete planting management afterward; fertilization and irrigation should both be determined according to growth conditions. Strengthen the management of the entire flowering and fruiting process, and reasonably regulate the fruit load; flower thinning, fruit thinning and bagging work should also be carried out simultaneously.
Cultivation Techniques for Sanhong Honey Pomelo
1. Flower thinning
During the flower bud morphological differentiation stage, thin the flowers on the fruiting mother branches. At the bud stage, first thin the inflorescences and then thin the flower buds, following the flower thinning principle of “removing the top and pinching off the tail, keeping the middle”, and selecting and retaining 2-3 robust flowers per cluster. All early summer shoots should be completely removed to concentrate the tree's nutrients for flower and fruit growth and development.
2. Fruit thinning
Reasonably regulating the fruit load per tree can effectively reduce the fruit granulation rate. Generally, the single fruit weight should be controlled at around 1.5 kg. After the physiological fruit drop in early May, determine the fruit retention amount in 2-3 sessions according to tree vigor, remove diseased, pest-damaged, deformed and weak fruits, and the retained fruits should be distributed as evenly as possible in the middle and lower parts of the canopy.
3. Bagging
Begin fruit bagging 60 days after the pomelo flowers fade. Before bagging (on a sunny day), thoroughly spray the entire orchard with efficient, low-toxicity, low-residue pesticides, and carry out bagging 4 hours after the spray liquid dries. Arrange the workload reasonably to ensure that fruit bagging can be completed within 3 days after spraying to guarantee pesticide efficacy and bagging results.
