There are three main objectives in young tree management of newly planted sweet oranges: survival, crown expansion and tree cultivation. Young trees have the characteristics of underdeveloped roots, slow growth, poor resistance and easy death.

In view of the above three objectives and the characteristics of young trees, the following measures are taken:

1, strengthen water management. Be sure to water it in time within one year after planting to prevent drought.

2. Strengthen soil and fertilizer management. Before fruiting, loosen the soil and weed once every two months or so to avoid the influence of weed roots on the development of young roots and promote the development of roots. At the same time, combined with topdressing, it can promote crown growth and enter the trial operation date early.

3, timely shaping and pruning. Young trees are mainly shaped. In the first year, keep suitable branches as backbone branches, and then cultivate branches by cutting them short. You can also let it grow, just cut off the very uncoordinated side branches, and then carry out plastic surgery one year before production.

4. Pest control. Insect pests mainly harm twigs and leaves, such as liriomyza sativae and aphids. , and should be timely spraying pesticides for prevention and control.
