(3) biological characteristics

Vigorous plant, a tall. GuiPing county hemp Dong town 40 year-old 5.7 meters tall, crown diameter x7.1 meters, dry weeks 72 1.32 meters. Your county east jin water stone 242 year-old high 10.6 m, crown diameter xl3.6 meters, 13.0 dry weeks 2.95 meters. According to 1978, young trees in nanning observation seeketh period late February spring, summer sought to late April late may and early September, autumn sought to late September, 12 month smoke winter tail. The first male period March 26 to April 6, the female flowers period April 8 to April 25; The second male period April 14 to April 27th. Fruit ripe period for June 20, belong to a medium. Peel easily discoloration, but more good storage pulp, long-lived. Because of its pulp thicker, fruit, including anthocyanidins less, won't get red, so the most suitable for processing sugar water cans, after treatment, pulp complete, color is beautiful, black, white, fertile land of impeller damper, relatively steady yield, anti-lodging planting, north flow county litchi field in 19 years per 4.25 kilograms, born to your county water stone in born in 242 per 680 kilograms. In dry land JiShou planting, and its branches easy sere and premature aging. The branch top soft brittle and longicorn moth larvae and wood stupid pestcide. Like Tolerance weaker, suitable for south area for planting. The cortex thicker, was easy to take root, the survival rate higher branches.

(4) varieties evaluation

Fruit-set rate is higher, DaXiaoNian results less obvious, a steady yield, anti-lodging. Quality is good, fresh flavor of dry, cans, are appropriate, particularly suitable for system in cans. Appropriate in a fertile waters, wet land for planting. Can choose appropriate growth where large Numbers development.
