1. Selection of pots and potting soil For potted kumquats, earthen tile pots with good air permeability should be selected. The bottom of the pot should be made of broken tiles as a drainage layer to facilitate drainage; potting soil should be selected with permeability. Good, relatively fertile, slightly acidic or neutral sandy loam, you can use five parts of leaf mold soil, three parts of pastoral soil, and two parts of fine river sand to prepare cultivation soil. It is best to spray and disinfect it before use. 2. Control of light and temperature. Kumquats like light, but are afraid of strong water. Excessive light can easily burn the leaves. In spring, it can be placed in a leeward and sunny place. In summer, it needs to be raised under a shade shed. In particular, direct sunlight at noon should be avoided. It can be exposed to sunlight before 9 a.m. and after 5 p.m. It also needs to be shaded for 30 hours in early autumn. % light. In late autumn and winter, it should be placed indoors in a sunny place to allow it to fully receive light. Kumquats like warmth. When the temperature drops below 10 degrees Celsius in late autumn, they should be moved indoors in time. In winter, it is best to keep the room temperature between 6 and 12 degrees Celsius. Too low a temperature will easily cause frost damage. Too high a temperature will affect plant dormancy, which is not conducive to flowering and fruiting next year. After the Qingming Festival in spring Windows can be opened appropriately for ventilation to gradually adapt to the outdoor temperature, and you can leave the room after the Grain Rain Festival; in summer, it should be placed in a shaded and ventilated place, and water should be sprayed frequently to humidify and cool down. 3. Management of water and fertilizer Kumquats like moisture, but are afraid of waterlogging. Water the kumquats. Water them once every three or four days from the time they leave the house in spring to the flowering period in early summer. Keep the pot soil moist at all times. After the young fruit stage, when the summer heat is high, you can water them once a day. Lack of water will not only cause the leaves to wilt. , and it is easy for the fruit to fall off. Avoid being exposed to rain on rainy days. If you are exposed to rain, drain the water in the basin promptly. As the temperature drops in autumn, the amount of plant transpiration also decreases, and the frequency and amount of watering should also be reduced. Watering can be done once every four days. At this time, heavy water can easily cause plant root rot; in winter, it can be watered indoors every Water thoroughly once every seven days. To fertilize kumquats, it is best to use liquid fertilizer. Liquid fertilizer can be applied every seven days after leaving the house in spring and before budding (mid-April to early June). From the flowering stage to the young fruit stage (early June to early July), apply liquid fertilizer every five days. Apply liquid fertilizer once and every ten days from fruit setting to the fruit growth period (early July to the end of September). The best effect is to apply liquid water that is mixed with sesame paste residue and water chestnut slices and then soaked in water to make the kumquats sour. It can make the plants grow vigorously, with many, big fruits and bright colors. 4. Repotting and Pruning Kumquats are generally repotted every three years or so, in late April after leaving the house. First knock the plant out of the pot, and use scissors to cut off the outer roots that are too dense. The size of the new pot depends on the growth of the plant. If it grows well, you should choose a large pot. The bottom of the pot also needs to be made of broken pot pieces as a drainage layer. After a layer of soil, put in a few pieces of horseshoe slices, and then another layer. Then place the plant on the soil, compact it while filling the soil, and finally water it thoroughly and place it in a shaded place. Kumquats are usually pruned once when repotting and after the beginning of autumn. Pruning in spring should be pruned again, mainly pruning over dense branches, drooping branches, and dead branches. During pruning at this time, attention should also be paid to giving the plant shape and making it more attractive. A "three forks and nine tops" trend is formed to make the tree crown grow into a round head shape. The summer and autumn shoots of the previous year should also be appropriately shortened, leaving only three or four buds. Pruning in autumn mainly involves pruning slender branches and ingrown branches. In addition, it is also very necessary to thin the fruits during the young fruit stage. Depending on the growth of the plant, 3 to 5 fruits can be retained on each branch, and the rest can be removed. In this way, not only will the remaining fruits grow large, but they will also have enough nutrients to supply them. Plant growth prevents excessive consumption of nutrients due to too many fruits. .
