Common problems in fertilization of pomelo

Grapefruit is a very common fruit in our daily life, which is grown all over our country. When planting grapefruit, if you want to improve the yield and quality of grapefruit, then fertilization is very important. A reasonable fertilization work is the key to ensure the efficiency of planting, but many people have a lot of problems when applying fertilizer. So what are the specific ones? Today, the editor has brought you common problems in pomelo fertilization. Let's take a look at it.

1. Insufficient organic fertilizer

In the cultivation of grapefruit, a large number of growers do not pay attention to the application of organic fertilizer, insufficient application, some even do not apply, think that only rely on chemical fertilizer to ensure the yield. However, the compound fertilizer commonly used in the market can not meet the growth and nutrition needs of grapefruit trees. The growth of grapefruit needs more than a dozen kinds of nutrients, while compound fertilizer has only about 5 kinds of nutrients, so if the nutrients are insufficient, it is very disadvantageous to the yield and quality of grapefruit. Therefore, when we apply fertilizer, we must pay attention to the application of sufficient organic fertilizer.

2. Do not pay attention to the characteristics of fertilizer demand

In the growing period, grapefruit trees generally have the growth process of young tree stage, early fruit stage, full fruit stage and then old tree stage. In the growth process of grapefruit tree, the demand for fertilizer nutrition is different in each period. Among them, even in the full fruiting period, the different phenological periods have different effects on the number of fertilizers. However, when planting, many growers only pay attention to the fruit fertilizer of grapefruit trees and the trees put into production. No attention has been paid to the fertilization of grapefruit trees before and after fruit harvest and the fertilization of young trees, which leads to the phenomenon of falling flowers and fruits.

3. Soil conditions are not suitable.

If the cultivated soil is different, then the physical and chemical properties of grapefruit will be different. Some slightly acidic soil, the viscosity is relatively strong, although the water and fertilizer conservation is strong, but the permeability is relatively poor, and nitrogen, phosphorus, potassium and other nutrients are low. However, for some highly permeable soils, although permeable, the ability of fertilizer and water conservation is very poor. And most of the groundwater level is relatively high, and the content of some organic matter is relatively low. Therefore, because of the unsuitable soil conditions, the physical and chemical properties of grapefruit trees are very inappropriate, resulting in poor quality and low yield of grapefruit trees.

4. Improper selection of chemical fertilizer

Although the application of chemical fertilizer is very good for the growth of grapefruit trees, we should pay more attention to it. Especially when choosing chemical fertilizer, we can't just look at the packaging and price. As a result, the nature of fertilizer is ignored, the proportion of nutrition is inappropriate, and the amount of fertilizer application is not controlled. If you apply fertilizer blindly, it will not only lead to a decline in fertilizer efficiency, but also increase planting costs.

The above is a brief introduction to the common problems of pomelo fertilization. That's all for today's introduction. This article is for reference only. I hope it can help you all.
