What about the uneven size of orange fruits with the latest sugar?

Sugar tangerines often encounter uneven fruit size in the process of planting, and large fruits are easy to produce coarse fruits of poor quality, so how to solve the problem of different fruit sizes? Come and have a look with the editor.

1. Spraying foliar fertilizer

When the temperature just picks up in spring, the branches have a strong ability to resist pressure, which can cut short the vegetative branches, promote the sprouting of the spring shoots, and generally make the buds come out neatly in the spring shoots. At the same time, foliar fertilizer containing zinc, boron, magnesium and other elements was sprayed 2-3 times during flowering, which could promote the formation of flower buds and provide sufficient nutrition for new shoot growth and flowering. In addition, according to the discoloration of leaves, water and foliar fertilizer can be sprayed to the crown in time to quickly meet the nutrient needs of plant geese.

2. Anti-cracking fruit

Sugar orange is also prone to fruit cracking during the fruit expansion period, which will also cause different fruit quality, affect the yield to a certain extent, and form fruits of different sizes. Nutritive cytokinins can be sprayed 1-2 times before and after flowering, which can help young fruits to increase the number of cell proliferation. under the action of sufficient cytokinins, fruit is beneficial to fruit cell proliferation and fruit enlargement. in the future, the capacity of water and other substances will increase, so as to reduce fruit cracking.

3. Keep the fruit and fix the fruit

After the first physiological fruit drop, the deformed fruit, disease and insect fruit, too large fruit and too small fruit should be removed in time, and in the second physiological fruit drop, the fruit should be retained in accordance with the principle of more strong branches, less weak branches, more middle and lower parts, less top, proper inner chamber and combined with the ratio of leaf to fruit. Because under the conditions of tree potential and fertilizer and water, there is a certain limit to the nutrients accumulated by the tree or absorbed from the soil, so that there is a certain limit to the nutrients produced by the assimilation and alienation process of functional leaves. Therefore, when leaving too much fruit, the nutrition of the tree can not meet the remaining fruit, the fruit will be relatively small, or the tree nutrition can not support the growth and development of fruit and branches, there will be fruit drop phenomenon.
