What Causes Kiwi Fruit Leaf Drop? Latest Cause Analysis
Kiwi fruit is a relatively common fruit, and its nutritional value is very high. It is rich in nutrients and is welcomed by many people. Therefore, there are now also a great many people growing kiwi fruit. However, when growing kiwi fruit, the phenomenon of kiwi fruit leaf drop often occurs. So what is going on with kiwi fruit leaf drop? Below, the editor will give everyone a brief introduction. Let's take a look together!
1. High Temperature and Drought
High temperature and drought are one of the main causes of leaf drop in kiwi fruit. This is because under high temperature and drought conditions, kiwi fruit's respiration is strengthened, water evaporation speeds up, and the leaves are prone to water loss. Once the kiwi fruit tree does not have enough water to replenish the water lost through evaporation, the leaves will wilt from water loss, causing the leaves to scorch and drop. Therefore, we should pay attention to weather changes, do a good job of watering, and meet the water needs of kiwi fruit. If heavy rain falls on the soil after a long drought, it will also cause kiwi fruit leaf drop, so we should also pay a lot of attention to this.
2. Improper Pruning
Pruning is an indispensable management task when growing kiwi fruit. Reasonable pruning work is the key to improving the air permeability of the kiwi fruit tree. If pruning is unreasonable, causing the leaf canopy layer to be too dense or pruning too heavily, it will affect the photosynthesis of the kiwi fruit tree. This causes excessive nutrient consumption in the kiwi fruit tree, and the leaves fall off due to lack of nutrients. Therefore, we should do a good job of pruning, improving the air permeability inside the tree body through summer pruning, autumn pruning, and so on. Properly thin branches and remove leaves, maintain a reasonable fruit load, and so on, to enhance the growth vigor of the kiwi fruit tree.
3. Excessive Water
Excessive water is also very unfavorable to the growth of kiwi fruit trees. If there is too much soil moisture, it will reduce the air permeability of the soil, causing the root system to lack oxygen and be unable to breathe. This reduces the nutrient absorption capacity of the leaves, and at least the fruit will snatch nutrients from the leaves in the middle and lower parts of the tree body, thereby causing leaf drop in the middle and lower parts. And if it is in rainy weather for a long time, then the photosynthesis of the leaves will also be affected, inhibiting the kiwi fruit tree's own nutrient production and speeding up the leaf drop phenomenon. Therefore, we should pay attention to controlling the amount of watering well, and do a good job of clearing the orchard and plowing after the fruit is harvested. When the rainy season arrives, open ditches in time to drain water and avoid water accumulation.
4. Other Causes
If the kiwi fruit tree has too much fruit, it will affect leaf function, thereby speeding up leaf aging. Therefore, the fruit load should be reasonably controlled to avoid excessive nutrient consumption. Then there is fertilizer damage and pesticide damage. Fertilizer damage and pesticide damage usually cause the leaves of the kiwi fruit tree to be burned. This causes the leaves to turn black, dry up, drop, and so on. Therefore, we must control the amount of fertilizer and the amount of pesticide used well to avoid fertilizer damage and pesticide damage. Finally, there are also causes such as pests and diseases that will cause kiwi fruit leaf drop, so everyone must pay a lot of attention.
