Causes and control methods of yellow leaves of yellow fruit

Yellow fruit is a kind of fruit with strong aroma and strong taste. It likes the warm and humid environment. At present, it is mainly in the south of China, but in the process of yellow fruit planting, it is easy to have yellow leaves. Once the fruit trees return to the phenomenon of yellow leaves, the lack of nutrients synthesized by photosynthesis will seriously affect the growth and development of fruit trees, do not germinate for a long time, and even lead to a decline in yield. So what is the cause of yellow fruit and yellow leaves? Come and have a look with the editor.

First, yellow leaf causes

1. Lack of nutrients

We all know that the leaves of plants are green because they are made up of chlorophyll, that is, chloroplasts, which are important substances for plant photosynthesis. The chloroplasts in leaves also contain protein components, which will lead to a decrease in protein content in leaves when nitrogen deficiency occurs, resulting in the reduction of chloroplasts and yellow leaves of yellow fruits.

2. Excessive stagnant water

In the process of yellow peel fruit planting, because there is too much water, it will cause the root system to suffocate and rot, especially the young root system is the most prone to rot, and the root system loses the absorption of nutrients Nel. After a long time, the nutrients in the leaves are consumed, they will slowly age, fade and turn yellow.

II. Prevention and control methods

1. Strengthen the management of fertilizer and water

In the process of planting yellow fruit, topdressing should be carried out timely and irregularly according to different growth conditions, mainly rotten farm manure, reasonable collocation of biological bacterial fertilizer and compound fertilizer. Of course, the type of fertilization should be determined according to the planting environment, such as dry sloping land, in addition to fertilizer, the most important thing is to water to keep the soil moist for a long time, ensure adequate fertilizer and water, and provide adequate nutrients for the root system.

2. Trenching and drainage

Stagnant water is often caused by poor drainage, so it is necessary to ensure that the water level of the drainage ditch on rainy days is at least 20 centimeters above the root from the ground, and if there is water for a long time, it should be dug lower, mainly because the yellow fruit is afraid of water. so it must be drained in time after rain, usually watering should not be too much, it is recommended that small water should be watered frequently to keep the soil moist. As long as the drainage work is done in place, the root will rot because of stagnant water, and it will not be because of yellow leaf symptoms.
