The cultivation of Kumquat can be obtained by sowing, cutting and grafting. Grafting usually takes place from May to June, and results can be obtained one to two years after grafting. The best sowing time is from March to April every year. When sowing, the soil should be covered with 1-2cm and covered with film. After the seedlings are unearthed, they gradually lift the membrane, then remove the membrane after exercise, and stop fertilizing in autumn, so as to prevent the seedlings from growing too long and affect the overwintering. In the process of seedling growth, attention should be paid to picking the center to promote the thickening growth.
The seedlings with well-developed root system and strong growth were planted in pots before germination in spring. The flowerpots with a diameter of 20-25cm were selected, and a piece of broken tile was placed on the seepage hole. The cultivation soil is made up of rotten leaf soil and compost or horse manure soil. A 3cm edge is required to be set aside after potting to facilitate watering. 7-10 days after planting, the seedlings can develop new roots. At this time, the manure can be removed and fertilized. Generally, the pot can be poured once every 2-3 years. When the pot is changed, 40-50g cake fertilizer or slurry slag will be added as the base fertilizer, and the time will be in autumn, after the autumn turns green slightly.
In spring and autumn, water shall be poured every 2-3 days, and in summer, once a day in sunny days. The water content of basin soil shall be maintained about 70%. In winter, it can be determined by overwintering environment. Generally, water shall be poured every 7 days.
A little urea should be added in the florescence and fruit stage, and the concentration of liquid fertilizer should increase with the increase of growth.
The tree shape of Kumquat is natural semicircle or column or tower. Results the former pruning principle is to leave a 10 cm heavy cutting rod after the first shoot of single bud cutting and grafting is mature. After the main branch of Baosheng is lignified, the new shoot will be cut short and promoted. At the same time, the fertilizer and water will be strengthened to strive for multiple shoots in the same year and expand the crown.
