What causes mango flower and fruit drop? These 4 points are the main reasons
During cultivation, the phenomenon of flower and fruit drop in mangoes severely affects their yield, so what exactly causes this situation? Today we will talk about the reasons for mango flower and fruit drop, let's take a look together with the editor of Tuliu.com~
1. Temperature effects
1. During the flowering period and young fruit period of mango, if it encounters long-term low-temperature rainy weather, mango is relatively prone to flower and fruit drop. This is because when the temperature is too low, the plant's nutrient transport is particularly slow or stops directly, and in rainy weather it will cause soil compaction, resulting in poor soil permeability, decreased root respiration and absorption capacity, and the flowers and fruits cannot continue to grow without nutrients, and will fall off before long.
2. Moreover, rainy weather will also affect the activity of insects, resulting in relatively poor pollination effects, and it is especially likely to produce a large number of deformed and abortive fruits, which will naturally fall off in the later stage of growth. This is a physiological phenomenon.
2. Caused by pests and diseases
Another major cause of mango flower and fruit drop is erosion by pests and diseases. The main diseases of mango are anthracnose and powdery mildew. After the plant is infected with the disease, the flower spikes and young fruits will turn black, dry up, become necrotic, and even fall off. Or the plant turns brown and necrotic, causing the flower buds to fall off. The main pest is the mango shoot borer, which will absorb the sap of the flowers and leaves completely, causing them to dry up and fall off.
3. Insufficient nutrition
Mango needs to consume a large amount of nutrition during the growth period, just like a person growing their body, poor nutrition will lead to poor development. And especially when mango is flowering and fruiting, the nutrition at this time can account for 40 percent of the total nutrition, so the nutrient supply at this time will be insufficient, and the phenomenon of flower and fruit drop will occur.
4. Water effects
During the flowering and fruiting period of mango, a certain amount of water is needed. If the soil is too dry and lacks water, it will affect the growth of the plant and nutrient consumption, thus causing the flower buds to fall off. If there is a lack of water when the fruit is growing, the fruit will fall off. Because fruit is fruit, the largest proportion is water, and severe water shortage will lead to fruit drop.
The above are the main reasons causing mango flower and fruit drop. We hope it is of some help to growers. If you have any questions, you can comment and leave a message below, and the editor will reply to everyone in time. Remember to share and like.
