宿根蔗是指甘蔗地上部份收获后,在适当的水份、温度和空气环境条件下,使留在地下部份的蔗茎侧芽萌发出土成为新株,从而可以一次下种,进行多次收获的一种栽培制度。由于宿根蔗具有省工、省种、早熟高糖的优越性,因此,在甘蔗栽培制度中占有重要的地位。我省甘蔗产区历来都有留宿根的习惯,有的社队宿根面积占植蔗面积50％以上。但近年来不少社队的宿根蔗面积逐年减少,产量有逐年下降的趋势,这对蔗糖生产是不利的,因 Rooting sugarcane refers to the ground above the ground after the harvest, under the appropriate conditions of water, temperature and air environment, leaving the cane stems in the underground part of germination unearthed into a new strain, which can be a species, multiple harvest A cultivation system. Because of its advantages of labor-saving, provincial species and precocious high-sugar, crop-root cane occupies an important position in the sugarcane cultivation system. Sugarcane production areas in our province has always had the habit of staying root, and some commune and pest root area accounted for more than 50% of the area of ​​sugarcane. In recent years, however, the area of ​​perennial sugarcane in communes and communes has been decreasing year by year, and the yield has been declining year by year, which is unfavorable to sucrose production due to
