How to fertilize honey pomelo? Master the correct fertilization methods

The taste of honey pomelo is generally sweet and sour, with a slightly astringent note when eaten in large amounts, but it is a favorite of many people. People who eat honey pomelo regularly tend to have smoother and softer skin, which is also one reason for its popularity. Secondly, its medicinal value is also very high, so the market demand keeps improving. But how should honey pomelo be fertilized to ensure its yield and quality? Let's see how Qinnong.com does it.

Fertilization of young trees

Honey pomelo fertilization is mainly divided into two stages. First, let's talk about how honey pomelo is fertilized during the young tree stage. When planting, we should apply a heavy base fertilizer, mainly organic fertilizer, supplemented with an appropriate amount of potassium fertilizer and nitrogen fertilizer. About half a month after planting, we need to carry out topdressing. In order to promote the growth of honey pomelo branches and leaves, we need to use manure and urine water mixed with about 30 jin of urea for irrigation. During the growing period of young trees, one principle of fertilization is to apply frequently and lightly, generally once every half a month to a month. Finally, note that in winter, fertilization should be applied as deeply as possible, using the trenching method or the piling method, so that the honey pomelo trees can pass through winter smoothly.

Fertilization of mature trees

For adult pomelo trees, fertilization is generally divided into four stages. The amount and type of fertilizer used at each growth stage differ to some extent. Let's take a detailed look below.

1. Growth fertilizer

Growth fertilizer is generally applied in February or March each year, mainly to promote the growth of treetops. We mainly use urea, phosphate fertilizer and boron fertilizer. On average, each mu requires 100 jin of urea, 30 jin of phosphate fertilizer and 20 jin of boron fertilizer. Among these, urea is usually used for spraying, while phosphate fertilizer and boron fertilizer are applied by irrigation. Note that growth fertilizer generally needs to be applied twice, with a second application about half a month after the first, which can promote the flowering period to a certain extent.

2. Flower-promoting fertilizer

Flower-promoting fertilizer is generally applied twice, ten days before flowering and half a month after flowering. The first flower fertilizer is around April, mainly compound fertilizer, with an appropriate amount of phosphate fertilizer and potassium fertilizer sprayed. The second flower fertilizer is around May. We fertilize according to the growth condition of the honey pomelo and spray an appropriate amount of anti-drop agent, which can prevent fruit drop.

3. Fruit-strengthening fertilizer

Needless to say, fruit-strengthening fertilizer is meant to make honey pomelo grow large and good. The components of fruit-strengthening fertilizer are mainly organic fertilizer and high-efficiency potassium fertilizer. Organic fertilizer is usually applied deeply in trenches, but high-efficiency potassium fertilizer is generally applied by spraying. Finally, an appropriate amount of foliar fertilizer can also be sprayed.

4. Maintenance fertilizer

Maintenance fertilizer is actually what we usually call winter fertilizer. It is generally applied after the honey pomelo harvest and orchard cleanup. The most basic purpose of maintenance fertilizer is to help the honey pomelo trees overwinter smoothly. Secondly, it prevents the honey pomelo trees from aging. Finally, it prepares for high yield in the coming year. In fact, all of this is for high yield. Maintenance fertilizer is mainly organic decomposed fertilizer and compound fertilizer, applied deeply in trenches or in ring-shaped deep application.
