Detailed Explanation of Key Post-Harvest Management Techniques for Loquat
To overcome the alternate bearing phenomenon in loquat caused by poor management, post-harvest management must be strengthened to prepare for a good harvest next year. 1. Strengthen fertilizer and water management (1) In April-May after fruit harvest, apply fertilizer by the ring trench method around the perimeter beneath the tree canopy, applying 100 kg of decomposed human manure or cattle and pig pen manure per tree, ...
To overcome the alternate bearing phenomenon in loquat caused by poor management, post-harvest management must be strengthened to prepare for a good harvest next year.
1. Strengthen fertilizer and water management (1) In April-May after fruit harvest, apply fertilizer by the ring trench method around the perimeter beneath the tree canopy, applying 100 kg of decomposed human manure or cattle and pig pen manure per tree, plus 250 g of urea; (2) By August-September, before loquat flowering and bud emergence, open ring trenches and apply 5 kg of decomposed rapeseed cake or soybean cake fertilizer to promote robust flower bud growth; (3) In mid-December, apply 100 kg of burnt soil and plant ash or pond mud to the root zone or in ring trenches, which helps improve fruit set rate and promote spring shoots; (4) Water appropriately to combat drought, which benefits summer shoot growth.
2. Pest and disease control The main insect pests include longhorn beetles and yellow hairy caterpillars. For longhorn beetle larvae, manual capture or plugging the wormholes with pesticide can be used to kill them. When yellow hairy caterpillars cause damage in May-June, manual capture can be used, or spraying with dimethoate or trichlorfon at 100 times dilution. The main diseases include anthracnose and leaf spot. When leaves unfold, spray with 20% thiophanate-methyl at 800-1000 times dilution or 40% fosetyl-aluminum at 500 times dilution for prevention.
