摘　　要：该文针对山西春旱缺水造成缺苗断垄，严重制约农业稳产高产的状况，将行走式节水播种和苗期灌溉等机械化技术引入田间试验。从１９９７ 年到１９９８年在山西原平市和襄汾县布点，进行了大面积的试验示范作业，按照统一的试验项目和方法，进行了大量的数据测定，对不适合当地条件的机具性能进行了改革和完善，对试验结果进行了对比分析，以及经济和社会效益分析。分析结果表明，节水播种和苗期灌溉的试验田比不施水的对照田平均增产１１％ ～６４％ ；投入产出比为１．４７∶１；比人畜供水点播效率提高１０～１５ 倍；比管道节水灌溉平均每公顷节水９００ ｍ ３，对严重缺水干旱地区具有重要意义。Shanxi province is semi arid territory,and the quantity of water contained in the soil is insufficient for the growth of plants in spring.In order to solve this problem,some new techniques known as walking pattern water saving sowing,and furrow irrigating, was tried out.From 1997 to 1998,a large number of experiments about this item was carried out in Yuanpin and Xiangfen counties in Shanxi province and some important data were obtained by the experiments.By analysing these data, the result showed that certain amount of necerssary water during sowing by the techniques is the key to keep full stand and improve yield.
