甘蔗宿根栽培的优越性,主要是节省蔗种及劳力,错开农时,提早成熟,为糖厂提供早期原料,加速良种繁殖和解决秋、冬植蔗种苗来源。宿根蔗蔸上的芽长时间深埋土内,春暖后需及早开垄松蔸,促蔗芽萌发生长,如开垄不适时,松蔸不彻底,则老蔸发株少,造成缺苗断垄,有效茎少,产量不高。 Sugarcane pest cultivation superiority, mainly to save sugar cane and labor, staggered agricultural, early maturity for the sugar factory to provide early raw materials, accelerate seed multiplication and solve the autumn and winter sources of sugarcane seedlings. Pests on the root of cane stalks for a long time deep buried in the soil, the need to open up early after the spring loose pine, promote the growth of sugarcane germination, such as ridge discomfort, pine is not complete, the old seedlings less hair, resulting in lack of seedlings broken Ridge, less effective stems, the yield is not high.
