Dry Seeding and Wet Emergence Technology of Maize in Ningxia Yanghuang Irrigated Area

[目的]研究宁夏扬黄灌区滴灌玉米干播湿出技术。[方法]通过田间试验,研究了干播湿出、滴灌对玉米出苗率、耗水量、产量及其构成因子的影响。[结果]干播湿出可提高玉米的出苗率3.85%,干播湿出、滴灌减少玉米灌水量,可节水5 610 m3/hm2;产量及其构成因子与其他灌溉模式相比无差异。[结论]干播湿出技术具有节水和提高出苗的作用,可大面积推广。

[Objective] To research the dry seeding and wet emergence technology of maize in Ningxia Yanghuang irrigated area. [Method]Field trial was carried out to research the effects of dry seeding and wet emergence technology and drip irrigation on the emergence rate of maize,water consumption,yield and its component factors. [Result] Dry seeding and wet emergence technology could enhance the emergence rate of maize by 3. 85%. Dry seeding and wet emergence technology and drip irrigation reduced the irrigation water volume by 5 610 m^3/hm^2. There were no differences in yield and its component factors compared with other irrigation modes. [Conclusion]Dry seeding and wet emergence technology has the function of saving water and enhancing emergence rate,which can be widely promoted.
