What causes yellow leaves on wampee trees? A detailed guide to prevention and control methods
Wampee is a fruit with a rich aroma and intense flavor. It prefers a warm, humid environment, and in China it is currently grown mainly in the south, but yellowing leaves occur very easily during wampee cultivation. Once the fruit tree shows yellowing leaves again, the nutrients synthesized through photosynthesis are insufficient, which seriously affects the growth and development of the fruit tree, prevents it from sprouting for a long time, and may even cause a decline in yield. So what causes yellow leaves on wampee? Let's take a look together.
I. Causes of yellow leaves
1. Insufficient nutrients
We all know that plant leaves are green because these green colors are made up of chlorophyll, that is, chloroplasts, which are important substances for plants to carry out photosynthesis. The chloroplasts in the leaves also contain protein components. When nitrogen is deficient, the protein content in the leaves decreases, which in turn causes a reduction in chloroplasts and leads to yellow leaves on wampee.
2. Excessive water accumulation
During wampee cultivation, excessive water accumulation can cause the root system to suffocate and rot, especially the young tender roots, which rot most easily. The root system loses its ability to absorb nutrients. Over time, after the nutrients in the leaves are used up, they will gradually age, fade, and turn yellow.
II. Prevention and control methods
1. Strengthen fertilizer and water management
During wampee cultivation, topdressing should be carried out from time to time according to different growth conditions, mainly with decomposed farmyard manure, reasonably combined with biological bacterial fertilizer and compound fertilizer. Of course, the type of fertilizer still has to be determined according to the growing environment. For example, on dry slopes, in addition to supplementary fertilizer, the most critical thing is still to water to keep the soil moist for a long time, ensuring sufficient fertilizer and water and providing sufficient nutrients for the root system.
2. Dig ditches for drainage
Water accumulation is often caused by poor drainage, so make sure that on rainy days the water level in the drainage ditch is at least 20 cm above the ground near the roots. If water remains for a long time, dig it even lower. This is mainly because wampee is afraid of water, so after rain it must be drained promptly, and when watering normally it should not be too much either. It is recommended to water little and often, keeping the soil moist. As long as drainage is done properly, there will be no root rot caused by water accumulation, and no yellow leaf symptoms either.
