提早甘蔗植期,延长甘蔗生长期,仍是现阶段促进甘蔗高产、稳产、早熟、高糖的一条重要途径。多年的生产实践证明,秋植甘蔗一般比冬春植蔗增产20～40％,糖份提高0.5～2.66％。一个甘蔗生产地区或生产单位种植一定比例的秋植蔗(一般30～50％),对于提高蔗糖总产,提前糖厂开榨都有其重要作用。一、开展甘蔗“改制”研究的设想在五十年代初期,曾以早稻—秋植蔗两年两熟制发展3万多亩秋植蔗,单产比春植蔗成倍增长。但这种栽培制度挤掉了一造晚稻,与 Early sugarcane planting, to extend the growth of sugar cane, is still an important way to promote high yield, stable yield, precocious, high-sugar sugarcane at this stage. Years of production practice has proved that autumn planting sugar cane generally 20 ~ 40% increase in winter and spring sugar cane, sugar increased 0.5 ~ 2.66%. Planting a certain proportion of autumn sugarcane (usually 30-50%) in a sugar cane production area or production unit plays an important role in increasing the total sugar yield and opening the sugar mill in advance. First, to carry out sugarcane “reform” research hypothesis In the early 1950s, once in early rice - autumn two years of crop two years of development of more than 30000 acres of autumn sugarcane, doubled yield than spring cotyledons. But this cultivation system squeezed out a late rice, and
