In the young tree stage, longan trees need pruning. Pruning in this period is mainly to control the height of young trees, and constantly prune branches that grow too high at the top, so that a large number of lateral branches germinate, thus forming a vigorous crown and preparing for flowering and fruiting.

2. Mother branch culture

Not all the branches of longan trees can bear fruit, and not all the longan fruits grown on the branches can be healthy and full. Pruning at this stage is mainly to cut off branches that are too old, too delicate and moth-eaten, leaving healthy and mature branches for longan to bear fruit.

3, plastic pruning

After harvesting, longan trees should also be trimmed. This pruning is not to promote fruit, but to cut off all the remaining fruit stalks on the crown, the useless branches such as over branches, diseased branches, overlapping branches, cross branches and cross branches that have grown in the past, so as to make them sparse and ventilated.

4. Maintenance after cutting

After pruning, the wound left by pruning should be smeared or sprayed with disinfectant to kill germs at the wound. If possible, you can put some plant ash on it to speed up the collection and recovery of water, and add fertilizer in time to avoid plant malnutrition.

Extended data:

Longan is native to the south and southwest of China. Now China longan is mainly distributed in Guangdong, Guangxi, Fujian, Taiwan Province and other provinces (regions). In addition, Hainan, Sichuan, Yunnan and Guizhou provinces also have small-scale cultivation. The main producing areas are Guangdong, Guangxi and Fujian, among which Putian in Fujian has the best nutritional value and taste.

Putian City is located on the coast of the East China Sea and the west bank of the Taiwan Strait. Because of its unique geographical and climatic resources, it is extremely suitable for planting subtropical precious fruit trees such as longan. Among them, longan, loquat, litchi and honey pomelo are four traditional famous fruits in Putian, which have always been famous at home and abroad, especially longan, and are known as "Xinghua Longan is the best in the world".
