How to fertilize honey pomelo

Generally speaking, the taste of honey pomelo is sour and sweet with a little astringent taste, but it is the favorite of many people, and the skin of people who often eat honey pomelo will be smooth and tender, which is one of the reasons why it is popular. secondly, its medicinal value is also very high, so the market situation will be better and better, but how to fertilize pomelo to ensure its yield and quality? Now let's take a look at how the pro-farm network does it.

Fertilization of young trees

The fertilization of honey pomelo is mainly divided into two stages. first of all, let's talk about how to apply fertilizer in the young tree stage of honey pomelo. When planting, we should re-apply base fertilizer, mainly organic fertilizer, auxiliary use of appropriate amount of potash and nitrogen fertilizer. About half a month after planting, we have to top fertilize. In order to promote the growth of branches and leaves of pomelo trees, we need to irrigate them with about 30 jin of urea in feces and urine. One of the principles of fertilization during the growing period of young trees is to apply thin fertilizer frequently, usually every half a month to a month. Finally, it should be noted that we should apply fertilizer as deeply as possible in winter, and apply fertilizer by trenching or accumulation, so that the pomelo tree can get through the winter smoothly.

Mature tree fertilization

The fertilization of adult grapefruit trees is generally divided into four stages, and there are certain differences in the amount of fertilizer and the types of fertilizer used in each growth stage. Let's take a look at it in detail.

1. Growth fertilizer

Growth fertilizer is usually carried out in February and March every year, mainly to promote the growth of treetops. We mainly use urea, phosphate fertilizer and boron fertilizer, which need an average of 100 jin of urea, 30 jin of phosphate fertilizer and 20 jin of boron fertilizer per mu. Urea is usually used for spraying, while phosphate and boron fertilizer are irrigated. It should be noted that the growth fertilizer generally needs to be fertilized twice and re-fertilized about half a month after the first fertilization, which can promote flowering to a certain extent.

2. Fertilizer for promoting flowers

To promote flower fertilizer, we usually apply fertilizer twice ten days before flowering and half a month after flowering. The first flower fertilizer is around April, mainly based on compound fertilizer, and appropriate amount of phosphate and potash fertilizer. The second flower fertilizer is around May, we fertilize according to the growth of pomelo, and spray an appropriate amount of anti-falling element, which can prevent the occurrence of fruit drop.

3. Strong fruit fertilizer

There is no need to say much about the strong fruit fertilizer, we also know that it is for the pomelo to grow big and good, and the strong fruit fertilizer is mainly composed of organic fertilizer and high-efficiency potash fertilizer. Organic fertilizer is usually applied by deep trenching, but efficient potash fertilizer is usually carried out by spraying, and finally, an appropriate amount of foliar fertilizer can be sprayed.

4. Curing fertilizer

In fact, conservation fertilizer is what we usually call winter fertilizer, which is usually carried out after picking and clearing the garden. the first and most basic purpose of conservation fertilizer is to make the pomelo tree have a smooth fruit winter, and the second is to prevent the aging of honey pomelo trees. finally, it is to prepare for the high yield in the coming year, in fact, all this is for high yield. Conservation fertilizer is mainly organic fertilizer and coincidence fertilizer, ditching deep application or ring deep application.
