Latest Key Management Techniques for the Mango Fruiting Stage
When planting mangoes, many people know that the mango fruiting stage is the most important period. At this time, it is necessary to increase the fruit-setting rate, ensure the amount of fruit set, keep the fruit from dropping prematurely, and meet the nutritional needs of the fruit. Therefore, the fruiting stage is a crucial period that determines yield. We will now explain the specific management measures for the fruiting stage one by one.
1. Fertilizer and Water
Fruit-strengthening fertilizer needs to be applied during the fruiting stage. Generally, the period of fruit development is also the period when new shoots emerge. Therefore, sufficient nitrogen, phosphorus, and potassium must be supplemented, and no single nutrient should be over-applied. The balance between vegetative growth and reproductive growth must be maintained. In addition, boron fertilizer and calcium fertilizer needed by the fruit must be supplemented to avoid fruit drop and tree decline. The fruiting stage requires sufficient water, keeping soil moisture above 50%. Irrigation is roughly determined by how dry the soil is, but waterlogging must be avoided, and timely drainage should be carried out after rain.
2. Foliar Topdressing
During the flowering and fruiting stages, some growth regulators or hormones are used to protect flowers and fruit. These may cause unbalanced and disordered tree growth and lead to physiological fruit drop. Therefore, some good foliar fertilizers can be used to help regulate tree vigor, maintain normal growth, benefit fruit set, and also improve fruit quality.
3. Pay Attention to Pesticide Use
During the period when fruit is set, when diseases occur, pesticides must be chosen that are safe, efficient, environmentally friendly, free of phytotoxicity, and low in residue. Generally, powder-form pesticides should be used less, because powders pollute the environment more, drift easily, and have poor efficacy. Do not spray pesticides on windy or rainy days; it is ineffective and requires re-spraying, which increases residue. Common occurrences include mango angular leaf spot, downy mildew, and anthracnose, and jinggangmycin can be used for control. Mango fruit skin is thin, so emulsifiable concentrate pesticides should not be used, to avoid damaging the fruit.
4. Fruit Bagging
To prevent pests and diseases, pesticide damage, and pecking by animals, fruit bagging can generally be carried out after the second physiological fruit drop when fruit set is stable. Before bagging, the tree should be pruned once, and bagging should be done after spraying pesticide once. Bagging is best completed within one or two sunny days.
The above are some regulatory and management measures for the mango fruiting stage. As long as it is fruiting-stage management, it must be taken seriously, and various measures can be used for management, as long as they are beneficial to mango fruit set.
