摘要: 为了探索锡林河流域紫花苜蓿高效节水的最优灌溉制度,在田间灌溉试验基础上,研究了锡林河流域滴灌条件下紫花苜蓿的灌溉制度。利用WIN ISAREG模型对紫花苜蓿的实际灌溉制度进行了评价,在此基础上根据紫花苜蓿需水特性进行了多种灌水方案设计和模拟。研究表明:紫花苜蓿在现蕾期土壤水消耗比率最低,作物系数、产量反应系数和腾发量最大,为紫花苜蓿的需水关键期。紫花苜蓿生育期内共灌水10次,总灌水量在250 mm,产量下降率为6.0%。因此,研究结果为流域内紫花苜蓿的灌溉预报,以及当地灌溉人工草地建设提供参考。

Abstract: In order to research the efficient water-saving irrigation system of alfalfa in Xilin River Basin, based on field irrigation experiments, the irrigation system of alfalfa under drip irrigation in Xilin River Basin was studied. WIN ISAREG model was used to appraise the actual irrigation system. On this basis, multiple irrigation schemes design and simulation were conducted according to the water demand characteristics of alfalfa. The results showed that in the squaring stage, which was the critical period of water requirement of alfalfa, the soil water consumption rate was the lowest, and crop coefficient, yield response coefficient and evapotranspiration were the highest. Alfalfa field was irrigated ten times during the plant growth period, and the irrigation quantity was 250 mm, the rate of yield decline was 6.0%. The results can provide a reference for irrigation forecast of alfalfa and the irrigated artificial pasture construction in Xilin River Basin.
