1. Suitable area: Guangdong longan producing area. The geographical and climatic conditions for planting longan in western Guangdong are the best. The annual accumulated temperature is high, especially in spring, the temperature rises quickly, and the light is sufficient. The cultivated longan fruit is precocious, big and good in commodity.

2. Key points of cultivation techniques:

(1) Pruning of young longan trees. Small trees are pruned by thinning rather than cutting them short.

(2) Retraction and pruning of close-planted longan orchards. The earlier pruning leaves retract, the thicker branches are, which is more conducive to flowering and fruiting in the next year. Thinning method is adopted.

(3) Pruning in autumn. Dry the main branches or thicker branches year by year to cultivate timely and effective autumn shoots.

(4) control winter shoots to promote flowers. 1last shoot adjustment at the end of October165438+65438+early maturity in February.

(5) Promoting the formation of ear. Take effective technical measures to ensure the timely germination and growth of flower buds and make the ear grow and develop normally.

(6) Powerful flower and fruit protection technology. Spraying "Longan Fengguosu" and thinning flowers in bud stage can effectively control the amount of flowers and improve the fruit setting rate.

(7) Reasonable prevention and control of pests and diseases.
