Field management technology of mandarin

Wo orange is a kind of citrus, compared with other citrus varieties, it has the advantages of late ripening and high sugar, early fruiting and high yield, cold tolerance, drought tolerance, less fruit cracking, less fruit drop, resistance to storage and transportation, and the market season is the off-season of fruit, with high economic benefits. attract a lot of people to plant. So how to manage the cultivation of mandarin mandarin? Let's get to know it.

1. Post-planting management

After planting, it is necessary to keep the soil wet, do a good job of tree plate mulching, and apply thin compound fertilizer and water after half a month of planting, which can promote rooting and recovery. The bare root seedlings can be fertilized only when they sprout. Do a good job in stem fixing, plastic surgery, pest control and other work, for serious withered leaves can be all cut off, or sealed with microcrystal wax, reduce moisture evaporation, conducive to bud recovery.

2. Management of young trees

The principles of less application, frequent application, thin application and water fertilizer should be adopted in the fertilization of young trees. High nitrogen fertilizer should be applied mainly, and gluten water, mineral fulvic acid and alginic acid can be added. The concentration of water-soluble fertilizer can be 500-1000 times, and attention should be paid to the amount of leaching fertilization. in order to avoid excessive acidity and burn roots, it can also prevent excessive concentration of fertilization and root damage. It is necessary to do a good job in drainage and irrigation to avoid fertilizer damage and waterlogging, re-apply organic fertilizer in winter to promote tree restoration and storage of nutrients, intercropping legume green manure if possible, interplanting to avoid high stalks and strong nutrient demand, and to distinguish between the primary and the secondary. Don't put the cart before the horse. Young trees also carry out the work of fixing the main pole, selecting the main branches, wiping buds, picking the heart, cutting short, etc., to cultivate excellent crowns, do a good job in pest prevention and control, and protect the growth of new shoots.

3. Result tree management

There is a contradiction between vegetative growth and reproductive growth in the first fruit tree, so the balance is the basis of high yield. attention should be paid to the application of nitrogen fertilizer to avoid excessive growth of branches and leaves, and phosphorus and potassium fertilizer should be combined with organic fertilizer to provide sufficient nutrients for flowering and fruiting. Spring is suitable for fertilization, spend less balanced fertilizer, spend more adapt to increase nitrogen fertilizer, properly remove some young shoots, reduce the competition for nutrients, pay attention to foliar spraying, speed up the green of new shoots; in summer, it is mainly to protect fruit, control shoots, prevent diseases and insect pests, support fruit and prevent stagnant water; in autumn, we should determine the time of shoot release, combined with drought resistance and topdressing of quick-acting fertilizer to control diseases and insect pests. In winter, we should pay attention to deciduous leaves, low temperature freezing injury, pericarp senescence, promoting coloring and so on.
