A Detailed Guide to the Latest Field Management Techniques for Orah Mandarins
Orah mandarin is a type of citrus. Compared with other citrus varieties, it has the advantages of late ripening and high sugar content, early fruiting and high yield, cold tolerance, drought tolerance, few cracked fruits, few dropped fruits, and good storage and transport tolerance. Moreover, its market season falls in the off-season for fruit, so its economic returns are relatively high, attracting many people to grow it. So how should Orah mandarins be managed during cultivation? Let's learn about it together.
1. Management after planting
After planting, keep the soil moist and do a good job of mulching the tree basin. Half a month after planting, you can drench with dilute compound fertilizer water to promote root growth and recovery. Bare-root seedlings can be fertilized only after they sprout. Do a good job of trunk setting, shaping, and pest and disease control. For severely wilted leaves, you can cut them all off, or seal them with microcrystalline wax to reduce water evaporation and help sprouting and recovery.

Fertilization of young trees should follow the principles of applying little, frequently, thinly, and with water-soluble fertilizer. Fertilization should mainly use high-nitrogen fertilizer, and bran water, mineral fulvic acid, and seaweed acid can be added for drenching. The concentration of water-soluble fertilizer can be a 500-1000 times solution. When drenching fertilizer, pay attention to the amount to avoid excessive acidity burning the roots, and also to prevent overly concentrated fertilizer from damaging the roots. Do a good job of drainage and irrigation to avoid fertilizer damage and waterlogging. In winter, apply organic fertilizer heavily to promote tree recovery and nutrient storage. If conditions permit, you can intercrop or relay crop leguminous green manure. In intercropping, avoid tall-stemmed crops and crops with strong nutrient demands. Distinguish primary from secondary, and do not put the cart before the horse. Young trees also need trunk setting, main branch selection, bud removal, pinching, and short pruning to cultivate a good canopy, and pest and disease prevention and control should be done well to protect new shoot growth.
3. Management of fruiting trees
Young fruiting trees have a contradiction between vegetative growth and reproductive growth, so balancing them is the foundation for high yield. When fertilizing, pay attention to the amount of nitrogen fertilizer applied to avoid excessive growth of branches and leaves. Phosphorus and potassium fertilizers should be combined with organic fertilizer to provide sufficient nutrients for flowering and fruiting. Spring is suitable for fertilization. When there are few flowers, balanced fertilizer should be the main choice; when there are many flowers, nitrogen fertilizer should be appropriately increased. Properly thin out some young shoots to reduce nutrient competition between shoots and flowers, pay attention to foliar spraying to speed up the greening of new shoots; in summer, focus on fruit retention, shoot control, pest and disease prevention, fruit support, and prevention of water accumulation; in autumn, determine the time for releasing shoots, combine drought resistance with topdressing quick-acting fertilizer, and prevent and control pests and diseases; in winter, pay attention to leaf drop, low-temperature freezing damage, peel aging, and promoting coloring.
