论文将底墒效应利用技术、土壤深松技术、秸秆覆盖技术、有限水分胁迫效应利用技术、喷施多功能防旱剂五项单项抗旱技术在冬小麦播前及各个发育阶段适时、适地综合集成,并给出了应用量化指标。于1998～2000年在河南、河北、山东省进行示范推广应用。结果表明:冬小麦干旱综合防御集成技术是通过各单项抗旱技术触发和优化冬小麦找水、增水、保水、节水、控水的五种水分利用机制,发挥了植物生理生态、土壤理化性状、土壤水库、麦田小气候效应和化学制剂喷施等多种防旱抗旱的效能,时间贯穿于冬小麦整个生育期,可实现持续防旱抗旱。集成技术具有比各单项技术更显著的增产、节水效果。在两个典型大旱年的情况下,集成技术使水分利用效率提高10.6%～53.7%,平均提高27.7%;小麦增产7.0%～42.3%,平均增产16.6%;每公顷增加纯收入490～1200元。 In this paper, five techniques of single-stage drought-resistance with multi-function drought-resistant agent applied in soil moisture before sowing and at various developmental stages are suitable for integrated application of soil moisture, soil subsoiling, straw mulching, limited water stress, And gives the application of quantitative indicators. From 1998 to 2000 in Henan, Hebei, Shandong Province for demonstration and application. The results showed that integrated technology of winter wheat drought comprehensive defense was to activate and optimize five water use mechanisms of winter wheat to find water, add water, retain water, save water and control water through various drought resistance technologies, and play an important role in plant physiology and ecology, soil physical and chemical properties, Reservoir, wheat microclimate effects and chemical spraying and other drought and drought resistance performance, the time throughout the winter wheat throughout the growing period, sustainable drought and drought can be achieved. Integrated technology has more significant than the individual technology to increase production, water-saving effect. In the two typical drought years, the integrated technology increased the water use efficiency by 10.6% -53.7% with an average increase of 27.7%; wheat increased by 7.0% -42.3% with an average increase of 16.6%; and the net income per hectare increased by 490-1200% yuan.
