What causes low mango yields?
Mango is a tropical fruit deeply loved by people. It has a refreshing taste and high nutritional value, and many farmers grow it. But during cultivation, it is found that mango yields are relatively low. What causes this? Let's take a look at the detailed explanation.
1. Adverse weather
Mango needs a certain period of low temperature during flower bud differentiation to stimulate its growth, and if it encounters continuous high temperatures during flower bud differentiation, it will have difficulty heading. In addition, although a brief period of low temperature can promote flower bud differentiation, low-temperature rainy weather is also unfavorable for fruit setting. If low-temperature rainy weather occurs after flowering, it will cause flower drop, poor pollination and a low fruit-setting rate. Therefore, pruning as well as flower and fruit thinning and light exposure should be done well to promote flower bud differentiation and increase the fruit-setting rate.
2. Insufficient nutrition
Insufficient fertilization and low soil nutrients make the fruit trees grow poorly, affecting yield and quality. This is especially true during the flowering and fruiting period, because the vegetative growth period is short, so the tree accumulates less nutrition. Many fruit farmers are seriously short of fertilizer during planting and do not apply fertilizer during the growth period, which leads to fewer flowers and fruits on the fruit trees, and in the later stage a large number of flower and fruit drops occur due to insufficient nutrition. Mango has a high nutritional demand during the flowering and fruiting period, so fertilizer should be applied in time to supplement nutrition. At the flower bud stage, apply flower-strengthening fertilizer in time to promote flower spike development. After the flowers fade, apply fruit-strengthening fertilizer to promote fruit development.
3. Physiological metabolic disorder
In production, many orchards spray paclobutrazol to force flowering, but due to the limited application of supporting cultivation techniques for flower forcing and long-term excessive medication, the physiological metabolism of the tree becomes disordered, resulting in poor flower spikes and an unreasonable ratio of female to male flowers, which leads to a low fruit-setting rate and serious flower and fruit drop. During flower bud differentiation, plant nutrient solution can be sprayed regularly to improve leaf photosynthesis, reduce pesticide residues, promote the absorption and utilization of fertilizer by stems and leaves, and ensure healthy growth of the tree.
4. Damage from pests and diseases
As the temperature rises, the flowering and fruiting period is the peak time for pests and diseases. Diseases at this time include anthracnose, powdery mildew, sooty mold and bacterial angular leaf spot, while insect pests include noctuid moths, short-headed leafhoppers, aphids and thrips. They all affect the yield and quality of mango, so pest and disease control work should be done well, and pests and diseases should be controlled promptly when they occur.
