研究了不同灌溉方式下冬小麦田间土壤水分变化特点及对小麦产量形成的影响。结果表明,渗灌浇根不浇地,冬小麦全生育期渗灌田0～20cm土壤表层含水量较低,比喷灌0～20cm土层土壤水分消耗小,比20～120cm土层土壤水分消耗多;2种灌溉方式120cm以下土层土壤含水量为冬小麦利用较少。渗灌比喷灌增产11.6％,比少灌增产17.6％,比喷灌节水57.1％,其水分利用效率为喷灌的1.35倍。
This paper studied the characteristics of soil moisture change and the effect on wheat yield under different irrigation patterns in winter wheat field. The results showed that the irrigated irrigated irrigated irrigated land had lower surface water content of 0-20 cm soil during the whole growing period of winter wheat, lower soil water consumption than 0-20 cm soil layer of sprinkler irrigation, more soil water consumption than 20-120 cm soil layer The soil water content under the two kinds of irrigation methods below 120 cm was less utilized by winter wheat. Compared with sprinkler irrigation, subsurface irrigation increased yield by 11.6%, 17.6% less irrigation and 57.1% than sprinkler irrigation, and its water use efficiency was 1.35 times of sprinkler irrigation.
