What does the longan tree look like?

Longan, also known as longan, is one of the common fruits in supermarkets and fruit stores. Compared with the longan fruit, the tree does not understand it. What does the longan tree look like? How do you breed?

What does the longan tree look like?

Longan tree is an evergreen tree with a tall body. Mostly even-pinnately compound leaves, leaflets opposite or alternate; panicles terminal or axillary; fruit globose, seeds black, glossy. The florescence is from March to April and the fruiting period is from July to August.

Second, how does longan tree breed?

The propagation methods of longan tree include seed propagation, strip propagation, grafting propagation and so on. In addition, longan planted with seeds can bear fruit, but compared with grafted seedlings, the fruit of seedlings planted with seeds will be delayed for three or four years, and the quality is not necessarily good. At the same time, because of the great variation of seed reproduction and the late entry into the fruiting stage, grafted seedlings are generally not used in production and cultivation. However, I think people plant longan trees mostly for fun, so they can still sow longan seeds and bear fruit. The following points should be paid attention to when grafting longan:

1. time

Longan is suitable for grafting in sunny days with stable temperature, the best period is from mid-March to mid-April, the survival rate is more than 90%, the temperature is high in autumn, and the survival rate of grafting is not high.

two。 Prepare for

Choose to be a good rootstock and strong ear. Choose one-or two-year-old summer and autumn shoots with no diseases and insect pests and full axillary buds as scions. Pick it up and pick it up on the same day, apply wet cloth bandaging and sand storage to keep fresh.

3. Method

Generally speaking, double bud grafting has a high survival rate and concentrated nutrients. The method is to cut the cutting surface into two buds of one side long and one short, sow them at the forming layer, and then wrap the scion with a special film for grafting, completely closed, leaving no bud eyes, reducing water evaporation and improving the survival rate. Attention should be paid to cutting with cutting and cutting with cutting, so as to prevent the wound from drying and affecting the survival rate.

4. Administration and Management

After the grafting survived, when the grafting was slightly longer than 30-40cm, the heart was picked to promote aging and branching, and at the same time, the dense branches were thinned to form a round crown. And it can be sprayed for pest control.
