1. Plastic trimming. Selecting mid-late maturing varieties with strong regeneration ability, pruning and defoliation are carried out at the end of eggplant harvesting in the middle and late August. The cutting mouth can be 2-3 cm above the branches of "eggplant tree" or12-15 cm above the ground on the main stem, all the upper branches and leaves are removed, and 3-4 robust lateral buds are retained after the new buds germinate.
2. Promote new shoots. Five to seven days before pruning, apply one ton of decomposed human and animal manure water or 60 to 80 kilograms of high-quality decomposed cake fertilizer per mu, furrow deeply and apply it to 20 cm next to 15, and then cover the soil. After pruning, combine intertillage weeding, apply 8- 10 kg urea and 2000 kg water per mu, water the roots, keep water and increase fertilizer, and promote multiple quick buds.
3. Strengthen cultural management. After pruning, it is in the high temperature and dry season, and the new branches grow fast, blossom and bear fruit early, so it is necessary to supply fertilizer and water in time. During the growth of new branches, combined with intertillage and weeding, the seedlings should be topdressing for 2-3 times, watered for 3-4 times according to the weather and soil conditions, and topdressing high-quality compound fertilizer 10- 15 kg or urea 8- 10 kg per mu each time to meet the nutrient requirements of the vigorous growth and multi-bearing of Kandelia candel. Generally, fruits can be harvested 30 ~ 35 days after pruning.
4. Control pests and diseases. After pruning, the field temperature is high, the humidity is low, and there are many pests and diseases. The reserved lateral buds and new leaves should be protected by timely application of pesticides. 1.8% avermectin EC 1500 times solution, 48% riksbane EC 1000 times solution or 20% acarbose EC 1500 times solution can be used for tea yellow mite, eggplant moth and ladybug.
