How to Fertilize a Pomelo Tree? A Full Breakdown of the Latest Techniques
The pomelo is a fruit belonging to the citrus tree family, and it has a very large planting area in our country. When growing pomelo trees, we need to do a good job of management, especially fertilization management. If fertilization is done improperly, then it is very unfavorable for the growth of the pomelo, so everyone must pay attention to reasonable fertilization when planting. So how should the pomelo be fertilized? Today, the editor has brought you the fertilization techniques for pomelo trees, so let us take a look together below!
1. Reasonable application of organic and inorganic fertilizers
Farmyard manure contains a great many nutrients, has relatively good and stable fertilizer effect, and is very effective at improving soil structure. It can greatly help the yield and quality of the pomelo. However, when applying farmyard manure, we must pay attention to fully decomposing the farmyard manure. But in farmyard manure, the content of major elements such as nitrogen, phosphorus and potassium is relatively low, and it cannot meet the pomelo tree's demand for these elements. So we must also pay attention to appropriately adding some inorganic fertilizers such as nitrogen and potassium, magnesium and boron.
2. Fertilize according to tree vigor
When fertilizing, we must first check the age of the pomelo tree. Different tree ages mean the fertilizers applied are also somewhat different. Then there are also the phenological period of the pomelo tree, the amount of flowers and fruit, and the tree vigor, etc., to determine the type and amount of fertilizer. During the young tree stage of the pomelo tree, fertilization should follow the principle of small amounts applied many times, mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer, to ensure the amount of branches and leaves and achieve the goal of stable and high yield. Then during the flowering stage, flower bud differentiation and young fruit stage of the pomelo tree, the amount of phosphorus fertilizer should be increased. If the tree vigor is too vigorous, then nitrogen fertilizer application should be controlled.
3. Fertilize according to growth stage
In March, half a month before the pomelo tree sprouts, the fertilizer should be mainly nitrogen fertilizer. Apply an appropriate amount of phosphorus and potassium fertilizer in combination to promote the pomelo tree to send out spring shoots. This fertilization has a great impact on the yield of the pomelo tree in the current year and the next year, so it should be done as early and as quickly as possible. Then after the fruit gradually swells, it is still mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer. By the fruit growth stage, the demand for fertilizer increases, so topdressing should be done in time to ensure tree vigor and ensure that the pomelo tree can overwinter normally. When fertilizing, organic fertilizer should be the main one, applied in combination with quick-acting fertilizer.
4. Fertilize according to soil properties
When growing pomelo trees, if the soil is red loam, then the fertilizer should be mainly alkaline fertilizer, and acidic fertilizer must not be applied. Also, an appropriate amount of plant ash and lime should be spread, and the application method should be mainly heavy application and deep application. However, be careful to control the number of fertilizer applications. And if it is paddy soil, then attention should be paid to fertilizing multiple times. The fertilizer should be dilute fertilizer or compound fertilizer with a relatively high concentration. Prevent the loss of fertilizer nutrients and improve the fertilizer utilization rate. Then soil testing and fertilizer recommendation should also be carried out, and the application amount of various fertilizers should be controlled according to the nutrient composition of the soil.
The above is a brief introduction to the fertilization techniques for pomelo trees. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
