A Detailed Guide to the Latest Fertilization Techniques and Methods for Honey Pomelo

The taste of honey pomelo is generally sweet and sour, with a slightly astringent aftertaste when eaten in large amounts, but it is still a favorite of many people, and those who eat honey pomelo regularly tend to have smoother and softer skin, which is also one reason for its popularity; next is its medicinal value, which is also very high, so the market conditions only keep getting better. But how should honey pomelo be fertilized to ensure its yield and quality? Let us now see how Qinnong.com does it.

Fertilizing Young Trees

The fertilization of honey pomelo is mainly divided into two stages. First, let us 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 apply a top dressing. 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 growth period of young trees, one principle of fertilization is to apply frequently and lightly, generally applying fertilizer once every half a month to a month. Finally, note that in winter, fertilization should be applied as deeply as possible, and by the trenching method or the piling method, so that the honey pomelo trees can pass through winter smoothly.

Fertilizing Mature Trees

For adult pomelo trees, fertilization is generally carried out in four stages. The amount and type of fertilizer used at each growth stage differ to some extent. Let us look at them specifically below.

1. Growth fertilizer

Growth fertilizer is generally applied in February and March each year, mainly to promote the growth of tree tips. 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. Urea is usually applied by 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 flowering 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 apply fertilizer according to the growth of the honey pomelo, and spray an appropriate amount of anti-drop agent, which can prevent fruit drop.

3. Fruit-strengthening fertilizer

Fruit-strengthening fertilizer, needless to say, is 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 by trenching, 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 has been harvested and the orchard has been cleaned. The most basic purpose of maintenance fertilizer is first to enable the honey pomelo trees to overwinter smoothly, second to prevent the honey pomelo trees from aging, and finally to prepare for high yield in the coming year. In fact, all of this is for high yield. Maintenance fertilizer is mainly organic rotten fertilizer and compound fertilizer, applied deeply by trenching or in a ring-shaped deep application.
