2. Nutrient solution formula: same as mango.
3. Cultivation management: medium and large flowerpots with a diameter of 20 ~ 40 cm should be evenly mixed and soaked in water before planting. When planting, first lay 1 layer 3-4cm thick ceramsite on the bottom of the pot as a drainage layer, then remove the soil from the pot planted with soil, clean it and plant it in a mixed matrix, and then lay 1 layer ceramsite on the surface of the flowerpot.
After kumquat is planted, the nutrient solution should be poured until the exudate is seen in the tray at the bottom of the basin; On weekdays, the liquid is injected 1 time every week, with 500 ~ 1500ml in the big basin and 0 ~ 00 ~ 200ml in the middle basin. Increase rehydration times 1 time from bud stage. Water should be replenished on weekdays, and the substrate should be kept moist and dry, or liquid should be used instead of water, or less water should be used. Do not store water in the tray for a long time to avoid root rot. The shaping, pruning and pest control of soilless kumquat are the same as those of soil-grown kumquat.
