In the whole process of citrus planting, the autumn shoot of citrus is very important, and it is also the most prone period of citrus diseases. How to manage the autumn shoot period to improve the flowering and fruiting rate in the coming year? Mainly manage the following aspects:

1, shaping and pruning the sprouted autumn buds.

After coring and cutting, cut off longer branches to control the quantity and quality of autumn shoots. Cutting off the tops of branches that have not stopped growing in time, forcing them to stop growing and increasing the nutrient reflux of the tree can restore the vitality of the tree, promote the differentiation of flower buds and enhance the cold resistance of the tree. The young trees will be remolded in late September. Although the branches have high toughness, the young trees will be pulled out and reshaped to facilitate the early formation of the crown.

2. Control pests and diseases

Starscream, September is the peak season for Starscream. At this time, the morphology of various insects is mixed, and the phenomenon of generation overlap is serious. When choosing drugs, we should kill eggs, young mites, nymph mites and adult mites. The occurrence of thrips is also serious, which destroys autumn shoots and makes young leaves curl and deform. It is necessary to insist on applying medicine to the shoots for 2-3 times.

3. Key points of fertilization in autumn

Apply more fertilizer to strengthen seedlings and fruits. In the middle and late stage of autumn shoot growth, the fruit expands rapidly, the buds begin to differentiate, and the nutritional needs of fruit trees increase. Fertilizing strong seedlings and fruits is the key. At this time, decomposed organic fertilizer, phosphorus and potassium fertilizer are mainly used, and appropriate nitrogen fertilizer is applied, combined with foliar spraying, to promote the autumn buds to turn green. Water management and fruit expansion period are very important to the formation of fruit quality. At this time, soil moisture has a great influence on fruit quality. High soil moisture will promote vegetative growth and have a negative impact on fruit quality and flower bud formation. In order to increase the sugar content of fruit juice, the soil can be relatively dry.

The management of citrus autumn shoots is very important for high yield in the coming year, so we should pay attention to the methods.
