When it comes to citrus, most of my friends love it very much. However, when citrus is planted, it is possible to encounter the yellowing of the fruit, which also makes the final quality of the fruit, as well as the quality is not very good, or even sell for what price. But many people are not clear about the yellowing of citrus, what are the reasons for it? Let's take a look.
1. Improper application of fertilizer
One of the main reasons for the yellowing of citrus is that when fertilizer is applied, more fertilizer is applied in order to pursue higher yields. In these quick-acting fertilizers, some trace elements contained in them will change the quality of citrus. Some farmers in the process of fertilization, although they will apply more fertilizer, but ignore the importance of organic fertilizer, which makes the citrus orchard lack some necessary elements, resulting in citrus yellowing and other phenomena. However, if the fertilizer chosen is not suitable for planting soil when fertilizing, it will also cause problems with citrus fruits.
2. Problems with citrus roots
If there is a problem with the root of the citrus, it will also hinder the absorption of nutrients in the citrus, which will affect the growth of the citrus fruit tree. Usually the hanging fruit of the citrus tree, if there are more, will make the root of the citrus lack a lot of nutrients, because all the nutrients are absorbed by the fruit.
Sometimes, improper management of citrus water and fertilizer will also cause rotting in the roots of citrus. It may also cause root damage due to the burning of the root due to the chemical fertilizer, so when fertilizing or watering, it is necessary to control the distance of the fruit tree, and also do a good job of drainage.
3. The impact of pests and diseases
If citrus is affected by pests and diseases, it will also hinder the transmission of nutrients in the rhizomes of citrus fruit trees. Over time, it can also cause the roots or branches of the citrus to ulcerate or yellow, resulting in yellowing of the citrus fruit.
Then when planting citrus, we must also do a good job in the prevention and control of pests and diseases to prevent some diseases and insect pests from causing harm to various parts of the citrus. For example, the harm of root-knot nematodes is very large, and some ulcer diseases are very deadly for the striking nature of citrus.
In fact, in the process of planting citrus, whether it is the impact of pests and diseases, or water and fertilizer, the main thing is that the growth of citrus itself is not very good, so it will lead to the emergence of these problems. Then only by making the citrus root more and more developed, the ability to grasp the ground become more and more powerful, and the ability to absorb nutrients is stronger, can this series of problems be solved. Then farmers should also adjust according to the actual situation of citrus, targeted fertilization, disease and pest control, in order to make citrus grow better.
