甘蔗梢尖由于较脆易断,而且蔗梢糖分含量低,影响出粮率。长期以来,一直被人们视为“废物”而丢弃。如果采用梢尖留种,既可节约用种(每667平方米可节省用种400公斤),又可提高原料蔗的质量和糖分。近两年来,我场梢尖留种面积逐年增加,仅1994年全场梢尖留种总面积达54公顷,平均每667平方米产量在5.5吨以上,比全茎留种增加1吨以上。而且采用梢尖留种后的原料蔗糖分可达15.34％,比全茎原料蔗糖分提高1.45个百分点。采用蔗梢留种,应掌握好如下几点:
Sugarcane tip due to more brittle and fragile, and sugarcane sugar content is low, affecting the grain yield. For a long time, people have been discarded as “waste”. If you use the tip to stay species, both to save seed (each of 667 square meters can save 400 kg), but also improve the quality of raw materials and sugar cane. Over the past two years, the number of species in our field has been increasing year by year. In 1994 alone, the total area for spawning species was 54 hectares, with an average output of 5.5 tons per 667 square meters and an increase of 1 ton more than that of the whole stem. And the use of the tip after the remaining species of raw sugar up to 15.34% sucrose, sugar than the whole stem raw material increased 1.45 percentage points. Cotyledons to stay species, should grasp the following points:
