1. Kumquat is mainly fertilized when it germinates in spring, and only nitrogen fertilizer is applied once a week. The first time was spring fertilization, which was carried out in early February. The fertilizer is mainly slow-acting organic decomposed fertilizer, and the quick-acting fertilizer is applied appropriately. The second time was fertilization in summer, which was carried out in early June to provide nutrition for its flowering and fruiting. 2. When applying autumn fertilizer to kumquat, it is carried out in the middle of June at 5438+ 10, which can supplement the nutritional deficiency after flowering, prepare for overwintering and improve the cold resistance. Mainly quick-acting fertilizers. After the fourth fruit setting, 2% potassium dihydrogen phosphate aqueous solution should be sprayed on the leaves, but the amount of fertilization should not be too much.

What fertilizer does kumquat apply?

Kumquat likes fat meat. Pay attention to the supplement of trace elements such as nitrogen, phosphorus and potassium when applying fertilizer. Common fertilizer can be used, and the special fertilizer is pear flower, which is rich in nutrition and can promote the growth, health and vitality of potted kumquat. Potted kumquat can quickly absorb and utilize nutrients.

Fertilization method of kumquat

1. Kumquat trees are in vegetative growth period when they are young. At this time, it is necessary to provide sufficient nutrients for the growth and development of young trees, promote strong branches, and make them form high-yield crowns quickly. 2. Kumquat is in full fruit stage, and there is a great demand for fertilizer. At this time, if insufficient fertilization will greatly affect the yield and tree potential, you can apply 15- 15-30TE molar high-potassium water-soluble fertilizer, 5 kg per mu, once every 15 days. 3. Kumquat should be topdressing once in time after fruit picking. Combined application of potassium fertilizer and phosphorus fertilizer can restore tree vigor as soon as possible, supplement plant nutrition, enhance cold resistance of trees and promote nutrient accumulation.

Matters needing attention in fertilization of kumquat

If kumquat trees grow vigorously and apply less nitrogen fertilizer; Otherwise, kumquat trees will grow vigorously, and the fruit will probably fall.
