The Latest Solutions for Uneven Fruit Size in Mandarin Oranges

During cultivation, mandarin oranges often encounter uneven fruit size, and large fruits are very prone to developing poor-quality coarse-skinned fruit. So how should uneven fruit size in mandarin oranges be solved? Follow the editor and take a look.

1. Spray foliar fertilizer

When the spring temperature has just begun to rise, the branches have relatively strong pressure resistance at this time, and the vegetative branches can be cut back to promote the sprouting of spring shoots, which generally allows flower buds to emerge neatly on the spring shoots. At the same time, during the flowering period, promptly spray 2-3 times a foliar fertilizer containing elements such as zinc, boron and magnesium, which can promote flower bud formation and also provide sufficient nutrients for new shoot growth and flowering. In addition, according to the fading condition of the leaves, promptly spray the tree canopy with water and foliar fertilizer to quickly meet the plant's nutrient needs.

2. Prevent fruit cracking

During the fruit expansion period, mandarin oranges are also very prone to fruit cracking, which can also cause inconsistent fruit quality, have a certain impact on yield, and also form fruits of uneven size. Before and after flower drop, spray 1-2 times a nutritional cytokinin, which can help young fruit increase the number of cell proliferations. With sufficient cytokinin, the fruit is conducive to fruit cell proliferation and thus fruit enlargement, and in the future its capacity to hold water and other substances increases, thereby reducing fruit cracking.

3. Fruit retention and fruit setting

After the first physiological fruit drop, promptly remove deformed fruit, diseased and insect-damaged fruit, overly large fruit and overly small fruit. After the second physiological fruit drop, promptly retain and set fruit according to the principles of keeping more on strong branches and fewer on weak branches, keeping more on the middle and lower parts and fewer at the top, keeping an appropriate amount in the inner canopy, and combining these with the leaf-to-fruit ratio. This is because, under the conditions of tree age, tree vigor and fertilizer and water, the nutrients accumulated by the tree body or absorbed from the soil, as well as the nutrients produced by the assimilation and dissimilation processes of functional leaves, are basically limited to a certain extent. Therefore, when too much fruit is retained, if the tree's nutrients cannot satisfy the retained fruit, the fruit will be relatively small, or if the tree's nutrients cannot support the growth and development of fruit and branches, fruit drop will occur.
