摘  要：
[目的]对当归在不同水肥处理下的需水量进行研究,为当归灌溉制度研究及GAP规范化种植提供理论依据。[方法]通过小区田间试验,依据试验结果进行理论统计分析,分析了当归在不同灌水施肥处理下的土壤水分变化规律、需水量和作物系数。[结果]不同处理0～37 cm深度土壤含水率变化、表层土壤含水率变化起伏较大,随着深度增加,土壤含水率变化较小;不同水肥处理对当归阶段需水量的影响,需水量与灌水量大小成正比,灌水量越大,需水量越高;在适宜灌溉条件下,当归整个生育期的日耗水强度从0.16～4.03不等,作物系数为0.37～1.26,全生育期需水量592.98 mm;当归的整个生育期作物系数变化趋势是先增大后减小。[结论]该研究结果对制定当归种植灌溉制度和GAP规范意义重大。

摘  要：
[Objective] The aim was to study water demand of angelica under different water and fertilizer treatment,provide theoretical basis for angelica irrigation system research and GAP standardization planting.[Method] Through the plot field test,the theoretical statistic analysis was carried out based on the experiment result,the soil moisture variation law,water demand,crop coefficient were analyzed under different irrigation and fertilization treatment.[Result] Under different treatments,0-37 cm depth soil moisture changed,with soil depth increasing,the soil moisture variation decreased.The relationship between water demand and irrigation was positive,with irrigation amount increasing,water demand increased.In the appropriate irrigation conditions,during the whole growth period,the water consumption strength was from 0.16 to 4.03,the crop coefficient was from 0.37 to 1.26,and water demand was 592.98 mm;the crop coefficient variation trend was firstly increasing and then decreasing.[Conclusion] The study has significant meaning for making angelica planting irrigation system and GAP standardization.
