Note that the new soil does not directly contact the roots. After the basin is installed, pour enough water to keep the soil moist, and there will be no sunshine for l0 days. After the plants resume their growth, they will be managed normally. Fertilization of potted kumquat by fertilizer and water management households should be timely and appropriately applied with thin fertilizer. Generally, in July and August in spring, organic fertilizer water 1 times as the main nitrogen fertilizer is applied, and 0. 1.2% urea and 0. 1% potassium phosphate are sprayed in time. After 10 months, no fertilizer is applied to the pot soil, and a small amount of diluted NPK stick mixture can be sprayed on the leaves every month. Watering should be based on different growth stages. Determine the amount and frequency of watering in different seasons. The principle of watering is to wait for the soil to dry before watering, and then water the rest. The flowering period should be controlled, the flowering period should be appropriately increased, and the watering amount should be appropriately reduced in the fruiting period to promote flowering and fruit setting and improve the ornamental effect.

In order to make the crown of home potted kumquat uniform and beautiful, promote the germination of stout branches and cultivate robust fruiting mother branches, it is necessary to carry out shaping and pruning during the growth process. Generally, 2/3 buds should be erased after spring buds germinate, weak or over-dense buds should be removed in summer and early autumn from June to early August, and all buds issued after mid-August should be erased. During the flowering and fruiting period, special attention should be paid to thinning flowers and fruits, improving fruit setting rate, keeping potted oranges hanging on all sides, and improving ornamental value. After viewing the fruits in winter, you can pick them all from the end of March to the beginning of April, and then cut them when changing pots from the vernal equinox to Qingming. Potted kumquat is often grafted with Broussonetia papyrifera as rootstock, and the grafting method is docking method, which is carried out in June. Rootstocks should be potted one year in advance. After the grafting survives, the seedlings should grow mainly in nutrition, so that they can grow into plants as soon as possible, and at the same time, they can be properly pruned to form a certain tree shape. Generally, kumquat seedlings that survived in that year should be watered 1 time every day or every other day, and liquid fertilizer should be applied 4 ~ 5 times in summer and autumn, mainly nitrogen fertilizer, with appropriate amount of phosphorus and potassium fertilizer. After the first frost, keep warm in the environment above 5 ~ 10Ci = for the winter. In March and April, change the pot. The culture soil can be humus, compost or horse manure, and a small amount of cake fertilizer or sauce residue is added. When changing pots, you must bring soil balls, adjust the growth through proper shaping and pruning, pour enough water after changing pots, and keep them in the greenhouse for 1 ~ 2 weeks.
