Pruning of orange trees is generally divided into three stages, namely, spring pruning, summer and autumn pruning and winter pruning. The specific time is as follows:

1, spring pruning

From early February to mid-March, before the orange trees begin to sprout, they are pruned in spring. Pruning in this period is mainly to shape and cultivate the crown and delete dead branches, pests and diseases, horizontal branches and long branches. Promote ventilation and light transmission of trees and enhance disease resistance. At the same time, the buds should be removed to avoid premature fruit and affect the development of the tree.

2, summer and autumn pruning

From early July to mid-August, the citrus trees are pruned in summer and autumn after the fruiting period. Pruning in this period is mainly to control the amount of fruit, cut off the unfruitful branches, save nutrient consumption and improve fruit quality. In addition, it is necessary to cut off the branches above the top, so that the branches below can get enough light to promote the germination of new branches.

3, winter pruning

Pruning in this period is mainly for renewing the aged branches, shortening or thinning the old fruiting branches, forcing the new fruiting branches to stay in the inner chamber or lower part, keeping the crown compact and balanced, and laying a good foundation for the next year's results.

Matters needing attention in orange tree cultivation

In the early stage of orange tree growth, it is necessary to prune and straighten out the shape frequently to improve the yield and quality. A certain amount of nitrogen, phosphorus and potassium fertilizer should be applied to citrus trees every year to improve the fruit setting rate and fruit quality. Weeds should be cleared regularly to eliminate pests and germs, so as to avoid adverse effects on the growth and development of citrus reticulata.

Keep the soil moist during the growth period of orange trees, and water it in time in case of drought. At the same time, we should also pay attention to irrigation methods to avoid excessive soil moisture and affect plant growth. Oranges should be harvested in time after ripening to avoid affecting the edible quality of fruits due to long-term storage.
