Reasons for low mango yields

Mango is a kind of tropical fruit which is deeply loved by people. It tastes refreshing and has high nutritional value. It has also been planted by many farmers. But what is the reason why it is found that the yield of mango is relatively low when planting? Let's take a look at the detailed introduction.

1. Bad weather

Mango needs a certain low temperature during flower bud differentiation in order to stimulate its growth, but it will be difficult to heading if it meets continuous high temperature during flower bud differentiation. In addition, although the temporary low temperature can promote its flower bud differentiation, but the low temperature overcast and rainy climate is also disadvantageous to its fruit setting, if the low temperature overcast and rainy climate occurs after flowering, it will cause the phenomenon of falling flowers, poor pollination and low fruit setting rate. Therefore, it is necessary to do a good job in pruning and fruit thinning to promote flower bud differentiation and improve fruit setting rate.

2. Lack of nutrition

Insufficient fertilization and less soil nutrients make the fruit trees grow poorly and affect the yield and quality, especially in the flowering and fruit stage, because the vegetative growth period is short, so the nutrient accumulation of the trees is less. Many fruit growers lack fertilizer seriously during planting and do not apply fertilizer during the growing period, which will lead to less flowering and fruiting of fruit trees, and a large number of falling flowers and fruits will be caused by lack of nutrition in the later stage. In the mango flower and fruit stage, there is a large demand for nutrition, so it is necessary to apply fertilizer in time to supplement nutrition, in the flower sprouting stage, apply strong flower fertilizer in time to promote the development of flower ear, and after flower fade, apply strong fruit fertilizer to promote fruit development.

3. Physiological and metabolic disorders

In production, many orchards will spray paclobutrazol to promote flowering, but due to the lack of application of cultivation techniques and long-term overuse of paclobutrazol, it will lead to the imbalance of physiological metabolism of trees, resulting in poor spikes and unreasonable ratio of male and female flowers. resulting in low fruit setting rate, serious flower and fruit drop. Plant nutrient solution can be sprayed regularly during flower bud differentiation to improve leaf photosynthesis, reduce pesticide residues, promote the absorption and utilization of fertilizers in stems and leaves, and ensure the healthy growth of trees.

4. Diseases and insect pests

With the rise of temperature, the flower and fruit stage is the peak period of diseases and insect pests, when the diseases are anthracnose, powdery mildew, soot, bacterial angular spot and so on, pests are night moth, short-headed leafhopper, aphids, thrips and so on. They will affect the yield and quality of mango, so it is necessary to do a good job in the prevention and control of diseases and insect pests.

The above is the introduction of the reasons for the low yield of mango. I hope it can help you. If you want to know more about it, please follow us.
