摘要
[目的]明确微喷调控灌水技术对吐哈盆地葡萄耗水特征的影响.[方法]测定吐哈盆地葡萄园在微喷调控技术下不同处理的土壤含水量等指标并分析各生育期不同阶段的耗水强度.[结果]在灌溉定额相同的条件下,不同微喷处理随着间隔时间的增大,总耗水量减少,其中CK处理总耗水量最大(697.5 mm),WP2次之(680.8 mm),WP5最低(616.8 mm).葡萄萌芽期的耗水强度为2.6 ～3.5mm/d,展叶期为2.6～3.5 mm/d,花期为5.4 ～6.4 mm/d,果粒膨大期为8.2～9.0mm/d,果实成熟期为2.5～3.1mm/d.各微喷处理耗水模数在整个生育期内的规律趋于一致,均呈现出先增大后减小的变化规律,在果实膨大期达到最大值,占整个生育期的33％ ～ 35％,其次是果实成熟期,占整个生育期的29％ ～ 32％,在萌芽期各处理耗水模数最低,为5％ ～7％.[结论]试验结果为提高葡萄水分利用效率和制定合理的灌溉制度提供了理论依据.
Abstract
[Objective] To clear effect of micro irrigation technology on water consumption characteristics of grape in Tu-Ha basin.[Method] We analyzed the water consumption of different stages through the determination of soil water content and water content in different stages of the grape garden under the micro spray control technology.[Result] The total water consumption was decreased with the increase of the time interval.The total water consumption of CK was the largest (697.5 mm),WP2 took the second place (680.8 mm),and WP5 was the lowest (616.8 mu).The water consumption intensity was 2.6-3.5 mm/d in the germination stage,was 2.6-3.5 mm/d in the flowering stage,was 5.4-6.4 mm/d in the flowering period,was 8.2-9.0 mm/d in fruit grain expanding stage,and was 2.5-3.1 mm/d in the fruit maturity stage.In the whole growth period,the water consumption modulus of each micro injection treatment had the same law,which all increased firstly and then decreased,and the maximum value appeared in fruit expanding stage was 33％-35％,secondly was 29％-32％ appeared in the fruit maturity stage,and the lowest value appeared in the germination stage,with 5％-7％.[Conclusion] The results provide theoretical basis for improving water use efficiency of grape and making up reasonable irrigation system.
