为解决吨粮田建设中因施用化肥多而导致灌水量大、小麦倒伏减产、生产成本高的问题,经过三个不同水文年的试验、示范验证和推广,提出了高产节水灌溉体系,包括输水渠道防渗、合理灌水、保护利用土壤水、降低生物水消耗等几个方面。应用该技术体系,除可节约灌溉用水39.6％外,还可调节地温、改土肥田、抑草、节能、省肥、增产,作物全年耗水量仅740mm,水分生产率为2.31kg/m~3,吨粮成本可降低29.8％。 In order to solve the problem of large amount of irrigation, low yield of wheat and high production cost due to the large amount of chemical fertilizers used in the construction of ton grain fields, the high yield water saving irrigation system was put forward after three different years of hydrological experiment, demonstration demonstration and popularization, including Impervious seepage waterway, reasonable irrigation, protection and utilization of soil water, reduce biological water consumption, and several other aspects. Application of the technology system, in addition to saving 39.6% of irrigation water, but also can adjust the temperature, soil and fertilizer, grass, energy saving, fertilizer, increase production, the annual water consumption of crops is only 740mm, the water productivity of 2.31kg / m ~ 3 , The cost of ton grain can be reduced by 29.8%.
