8～10月份是北方甘蔗生长成熟的关键时期,此期间由拔节生长的生殖期逐步转为增糖上色的成熟期。因此,加强水肥及配套措施的管理是非常重要的,必须抓好以下几点:一、浇水追肥,培土起埂。对于底肥不足、土质较差、前期追肥较少,墒情欠佳的蔗田,应在拔节前后结合浇水,每亩施入硫酸钾复合肥20公斤,尿素10公斤,随水撒入蔗田(生长后期少施或不施氮肥)或在倍土时埋入地下,以促茎秆增粗增色,增加含糖量。施肥后应马上培土起埂,高度不少于20厘米,以防风固株。
From August to October, the critical period for the growth and maturity of sugarcane in North China was a period during which the reproductive period of growing sugarcane was gradually changed to the maturation phase of adding sugar and coloring. Therefore, to strengthen the management of water and fertilizer and supporting measures is very important, we must do a good job the following points: First, topdressing water, earth from scratch. For lack of base fertilizer, poor soil quality, less top dressing, poor soil moisture cane fields, should be combined with watering before and after jointing, applying 20 kg of potassium sulfate compound fertilizer per acre, urea 10 kg, Less or no late growth nitrogen fertilizer) or buried in the times when the soil underground, in order to promote stem thickening and coloring, increase sugar content. Soil fertility should be immediately after soil fertilization, a height of not less than 20 cm, in order to prevent wind solid strains.
