中文摘要 | 对河西绿洲灌区调亏灌溉春小麦0~120cm土层的耗水特征、产量指标体系与阶段耗水量和不同生育时期土壤水分的相关关系进行了分析研究。结果表明,在调亏灌溉条件下,不同水分调亏处理、不同产量水平下春小麦阶段耗水量和日耗水强度差异较小;春小麦耗水模数全生育期变化趋势也较为一致,在播种分蘖期和分蘖拔节期最小,而拔节孕穗期南抽穗灌浆期最大;春小麦孕穗、抽穗期仍可进一步施以适时适度的较为严格的土壤水分调亏而不会降低小麦生产力,而降低成熟期的土壤含水量不仅不会降低小麦生产力,反而会提高其水分利用效率和供水效率。 |
英文摘要 | The soil water consumption in 0 to 120 cm layer in the spring wheat field,the correlations between the yield related variables and phasic water consumption and soil water contents during different developmental stages under regulated deficit irrigation (RDI) in Hexi oasis irrigation region were analyzed. The results indicated that no significances were found in phasic and daily water consumption among different water deficit treatments and under various yield performance levels, furthermore, the phasic crop water consumption ratio in total water use for spring wheat subjected to various RDI regimes performed similarly, minimized at both sowing to tiller and tiller to jointing and maximized at both jointing to booting and heading to filling. In addition, further timely, proper and strict soil water deficit during booting and heading of wheat could be exerted based on present study, without resulting in yield loss, while further decrease in soil water contents during wheat maturity not only would not result in wheat yield loss,but also would improve its water use efficiency and water supply use efficiency. |
