Summer is the citrus fruit expansion period: key points for summer management of citrus

     From early June to early August, citrus enters the critical period of summer management. At this time, citrus is in the fruit expansion period and the summer shoot sprouting period, as well as the damage period of the Chinese citrus fruit fly. Therefore, strengthening summer management of citrus orchards is very important for retaining fruit and increasing income. Below, based on the growth characteristics of citrus, several key technical points for citrus orchard management are proposed for the reference of citrus growers.

 

Citrus management


    I. Reasonable bud removal and scientific fruit setting:For young trees that have not yet borne fruit, when the summer shoots of citrus grow to about 5 leaves, pinch off the tips in time to promote branch maturity. For large fruiting trees, remove the summer shoots, and cut back the branches of citrus trees that have dropped flowers and fruit to stimulate the growth of early autumn shoots. At the same time, set fruit scientifically, with a leaf-to-fruit ratio of 30:1 for each citrus tree.


    II. Formula fertilization:Summer is the citrus fruit expansion period, so the nutrient supply for citrus trees must be sufficient. Generally, fruit-strengthening fertilizer is applied from June 15 to 20, and must be completed by early July at the latest. Fertilization should follow a formula, with a nitrogen, phosphorus, and potassium ratio of 10:8:6. In addition to soil fertilization, foliar spraying should also be carried out to increase tree nutrition from both above and below in all directions.


    III. Pest and disease control:Mainly prevent and control anthracnose, red spider mites, citrus blackfly, arrowhead scale, aphids, etc., to ensure healthy growth of citrus trees.


    IV. Drought resistance and drainage:During the citrus fruit expansion period, if drought occurs, the citrus orchard needs timely irrigation. After heavy rain, for low-lying and wet citrus orchards, drain accumulated water in time.
