2. Longan

Dried longan is longan, which can be eaten with most foods. Longan is rich in glucose, sucrose, protein, vitamins and minerals, among which nicotinic acid and vitamin K are rare in other fruits.

Propagation method of longan:

1, grafting seedling.

There are many grafting methods, such as bud grafting, tongue grafting, abdominal grafting, splicing, cutting, docking and bud grafting. The methods of bud grafting, tongue grafting and bud grafting are simple and feasible, and the survival rate is high. In addition, some areas also use high grafting to transform seedlings with small fruits, poor quality and low yield to improve economic benefits.

Generally, splicing is adopted. Grafting seedling has high propagation coefficient, can maintain the characteristics of famous varieties, bears early fruits, has high yield, developed roots, is suitable for mountain cultivation, has strong typhoon resistance, and is suitable for the development, cultivation and popularization of coastal hills.

2. High pressure seedling raising

Generally, from the end of March to the beginning of April, when longan juice flows, mature plants with no pests and diseases, strong growth and good quality are selected, and oblique branches and stems of about 4 cm are peeled in a ring with a length of about 2.5 cm at the base of branches and stems. After 5-7 days, wrap the annular peeling place with a rope with a special perforated two-piece pottery bowl or bamboo tube, then fill the bowl or bamboo tube with sticky mud, evenly wrap it around the annular peeling, and keep it moist.

After 3-4 months, when new roots grow in the pot, they can be sawed off and separated, transplanted in the shade for 1-2 years, and then planted in the garden. Those with good management conditions can also be planted directly. In addition, moss and straw are directly wrapped and peeled with soil, and then wrapped with plastic sheets to keep warm. New roots can grow after 5-6 weeks, and can be sawed off and transplanted in 2-3 months. It is convenient to use local materials.

The high-pressure seedling raising method is simple, which can maintain the excellent quality of famous varieties, put into production early, has short crown and is easy to manage. However, its propagation coefficient is low, its root system is shallow, its wind resistance is poor, and its drought resistance is weak when cultivated in mountainous areas, so it is suitable for cultivation in mountainous areas and surrounding areas.
