甘蔗收获后,留在土中的蔗头继续萌芽长成新植株,称为宿根蔗。我国栽培宿根蔗的历史悠久,分布普遍,种植面积约占总植蔗面积的40—50%。宿根蔗具有节种、省工、高产、高糖、提早成熟、提早开榨和增产食糖的特点。例如浙江省温州市天河公社五三大队,宿根蔗面积占80%多,一般可比新植蔗增产20—30%,含糖率增加1%以上。如该大队第七生产队,1979年10.6亩糖蔗中,有9.3亩是宿根蔗,红糖平均亩产达1,700斤。
After the sugarcane is harvested, the sugarcane head remaining in the soil continues to germinate and grow into a new plant, called a dormant sugarcane. Perennial cane cultivation in our country has a long history and widespread distribution, planting area accounts for about 40-50% of the total area of sugarcane. Habitat sugarcane with section species, labor, high yield, high sugar, premature, early open-pressed and increase sugar production characteristics. For example, the fifth and the third brigade of Tianhe commune in Wenzhou City, Zhejiang Province, the area of peanut sugarcane accounted for more than 80%, generally 20-30% more than that of new sugarcane and the sugar content increased by 1% or more. If the brigade of the seventh production team, in 1979, 10.6 acres of sugar cane, 9.3 acres of perennial sugarcane, brown sugar average yield of 1,700 pounds.
