糖料蔗高效节水灌溉制度的制定

Drafting of sugarcane efficient water-saving irrigation system

对近年来普遍用于高效节水灌溉设计的一次灌水定额法进行评价,提出采用旱作物传统灌溉制度计算常用的水量平衡法计算高效节水灌溉定额。并以新植糖料蔗为例,根据甘蔗传统灌溉试验资料、结合其种植技术及甘蔗高效节水示范区灌溉技术调查,采用水量平衡法对甘蔗高效节水灌溉制度进行分析。

Irrigation quota has been universally adopted in design of efficient water-saving irrigation works. The au-thor assessed this method and suggested to calculate water-saving irrigation quota by water balance method whichis often used in computation of dry crop traditional irrigation system. Taking newly planted sugarcane as example,according to traditional sugarcane irrigation test data,combined with the investigation results of planting technolo-gy and irrigation techniques adopted in sugarcane water-saving demonstration zone,the author analyzed the sugar-cane efficient water-saving irrigation system by water balance method.
