As the saying goes, only when the flowers bloom well can the fruits bear fruit well, and many fruit growers who grow sugar oranges will take measures to promote flowers in the production process in order to improve yield and quality. So how to promote the flower of sugar orange? Let's take a look.

1. Drugs to promote flowers

Drug flower promotion is a more common method, it is mainly through spraying multiple frustration, in order to inhibit the growth of sugar orange branches, but the spraying time should also be grasped. Generally speaking, after the autumn shoot is ripe, it is sprayed again, and then sprayed again every 20-30 days. This is a safe and effective method.

2. Cutting roots to promote flowers

For paddy fields or orchards with shallow roots, the roots should be cut after picking or December, and the roots should be cut off by hoeing around the crown. Young and strong trees can be hoed 4-5 inches deep, and middle-aged fruiting trees should be hoed shallowly. Must hoe daunt part of the surface root, and sun until the leaf color fades slightly in order to be effective. Root cutting is also a safer method to promote flowers, and the effect is better if combined with waterlogging.

3. Ring cutting or wire binding

For the strong and prosperous trees with deep main roots, ring cutting should be used to promote flowers, and ring cutting should be carried out in the middle and late December, young trees can cut the trunk, while big trees can cut the main branches better, and plants with weak potential should not be cut by ring. The canopy faded about 1 week after ring-cutting, and if the deep-root rootstocks were still green but not faded in mid-late January, they could be cut again. When there is a phenomenon of falling leaves after ring-cutting, it should be watered in time, fertilized in advance in spring, strong shoots and flowers, and can not be sprayed with stone-sulfur mixture, Songzhi mixture and other irritating pesticides after ring-cutting. On the other hand, the iron wire is used to ligate the dry branches with 14-16 iron wire, so that the 2 + 3 of the iron wire goes deep into the cortex without harming the xylem. According to the age of the tree, the trunk can be ligated to get the branches, and the iron wire will be released one month later according to the change of leaf color.

4. Bending and twisting branches

For young fruiting trees, especially those newly put into production, erect strong branches are more likely to appear. In order to promote this kind of branches to blossom and bear fruit, in addition to ring cutting, twisting branches can also be carried out. The practice is to bend the overgrown branches with straw grass or plastic bags when the autumn shoots are ripe, and the bag leaves fade from dark green to light green, while twisting branches twist the branches around by hand from the base of the branches, injuring the skin and xylem, and turning the leaves into light green.
