How to fertilize a pomelo tree? These fertilization techniques you need to master
The pomelo is a type of fruit belonging to the citrus family, and it is grown on a very large 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, it is very detrimental to the growth of the pomelo, so everyone must pay attention to rational fertilization when planting. So how should the pomelo be fertilized? Today, the editor brings you the fertilization techniques for pomelo trees. Let's take a look below!
1. Apply organic and inorganic fertilizers rationally
Farmyard manure contains a great many nutrients, has relatively good and stable fertilizer efficiency, and is very effective for 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 it. But farmyard manure contains relatively little of the major elements such as nitrogen, phosphorus and potassium, and cannot meet the pomelo tree's demand for these elements. So we should 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 should first check the age of the pomelo tree; the fertilizers applied differ depending on the tree age. Then there are also the phenological period of the pomelo tree, the amount of flowers and fruit, and the tree vigor, which 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 frequently, mainly nitrogen fertilizer with phosphorus and potassium fertilizer as a supplement, 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 excessively vigorous, then nitrogen fertilizer application should be controlled.
3. Fertilize according to the growth period
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 along with it 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 with phosphorus and potassium fertilizer as a supplement. By the fruit growth period, the demand for fertilizer increases, and 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 type, combined with the application of quick-acting fertilizer.
4. Fertilize according to soil properties
When growing pomelo trees, if the soil is red soil, 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 broadcast, and the application method should be mainly heavy application and deep application. However, be careful to control the number of fertilizer applications well. If it is paddy soil, then attention should be paid to applying fertilizer multiple times. The fertilizer should be dilute fertilizer or compound fertilizer with a relatively high concentration. This prevents the loss of fertilizer nutrients and improves fertilizer utilization. Then soil testing and fertilizer recommendation should also be carried out, controlling the application amount of various fertilizers 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 I hope it can help everyone!
