甘蔗生长需要的水份较多,水份含量占植株重量的70%以上,全生长期需要的水量约等于它的生产物干重的250—350倍。整个生长过程,除成熟期水份不宜太多,以免降低蔗汁浓度增加加工成本外,其余各生长期均须保持适当土壤水份,以满足甘蔗生长发育的需要。我省气候主要的特点是高温多湿,蒸发量大,雨量虽较丰沛,但分配不匀,仍有旱涝现象。每年四至九月为多雨季节,十至三月为干旱季节,而这些干旱时期刚好是甘藤萌芽及伸长盛期,土壤水份缺少,影响蔗芽的萌发及节间的伸长,所以要抓紧防旱灌溉。
Sugar cane growth requires more water, moisture content accounted for more than 70% of plant weight, the whole growth period of water is about equal to its production of 250-350 times the dry weight. The entire growth process, in addition to the maturity of the water should not be too much, so as not to reduce the concentration of sugar cane to increase processing costs, the rest of each growth period must maintain proper soil moisture to meet the needs of growth and development of sugarcane. Main features of our province’s climate is hot and humid, evaporation, although the rainfall is abundant, but the distribution is uneven, there are still droughts and floods. April to September each year is a rainy season, ten to March for the dry season, but these dry period is just buds of Germane and elongation period, the lack of soil moisture, affecting the germination of buds and internodes elongation, so to Pay close attention to drought-resistant irrigation.
