以抗旱早熟高糖甘蔗品种云蔗03-194为试验材料，通过大田试验研究了成熟期缺水和灌水对蔗田土壤水分变化及甘蔗品质、产量性状的影响。结果表明：在试验实施期内，0～20 cm土层的土壤含水量灌水处理是未灌水处理的1．05～1．40倍，20～40 cm土层的土壤含水量灌水处理是未灌水处理的1．45～1．58倍；甘蔗株高在试验前期均有增加，40 d后灌水处理的株高继续增加，未灌水处理的几乎不再增加；未灌水处理的绿叶数在整个甘蔗成熟过程中均减少，灌水处理的绿叶数灌水后20 d才开始逐渐减少，至甘蔗收获时灌水处理的绿叶数是未灌水处理的1．6倍；出汁率灌水处理比未灌水处理高出2～5个百分点；两个处理的蔗糖分没有明显的差别；纤维分在0～20 d内灌水处理比未灌水处理高出6个百分点，但至甘蔗收获时，两个处理的甘蔗纤维分的含量差别不大；蔗汁还原糖含量0～20 d内灌水处理呈现上升的趋势，20 d后开始下降，灌水处理是未灌水处理的1．75倍，至甘蔗收获时两个处理的蔗汁还原糖含量差别不大。

Through the field experiment,has researched the influence to soil moisture,yield and qulity components of sugarcane by the water shortage and irrigation in maturing stage,using the sugarcane variety of CYZ03-194 for the experiment material with drought resistant,early mature and high sugar content .The results shown that the soil moisture in 0~20 and 20~40 cm was higher than 1 .05~1 .40 and 1 .45~1 .58 times respectively,compared the irrigated treat-ment with non-irrigation .The plant height was kept increasing total in the earth experiment stage,but after 40 days,the plant height continue to increase only by the irrigated treatment .The number of green leaves was declined in whole ma-turing stage by the non-irrigation,but for the irrigated treatment it started to declining after 20 days of irrigation and was higher than 1 .6 times to the non-irrigated treatment .The juice ratio was higher than 2%~5%by the irrigated treat-ment .There was no significant difference between two treatments for the suger content .The fiber content was higher than 6%compared the irrigated treatment with the non-irrigation during 0~20 days,but no significant difference was found at the harvest .The sugar content in cane-juice was kept increasing trend during 0~20 days,but it was starded to decrease after 20 days by the irrigated treatment which was still higher than 1 .75 times to the non-irrigated treatment,however,no significant difference was found between two treatments at harvest .
