- 摘要:
- 隔沟灌溉技术是一项新型的节水灌溉技术,在国内外都已进行了较长时间的研究和推广,但在宁南山区尚没有推广应用的报道.2004年“北方半干旱集雨补灌旱作区(宁夏彭阳)节水农业技术体系集成与示范”课题引进该项技术,在宁夏彭阳王洼示范区进行了地膜玉米隔沟灌试验研究.结果表明,隔沟灌与全灌相比,产量相近,水分利用效率增加了12.44%,但用水量只有全灌的一半;与不灌溉相比,经济产量和水分利用效率分别增加了38.24%和38.65%.
- Abstract:
- The separate furrow irrigation is a new way of economizing irrigation,which has been investigated and popularized,but there is no report in southern Ningxia hill region.In Pengyang county,separate furrow irrigation of film maize was introduced.The result indicats:separate furrow irrigation is compared with full irrigation,the output is equal,water use efficiency add by(12.44%),using water quantity is half to full irrigation;compared with no irrigation,economic output and water use efficiency is increased 38.24% and 38.65% respectively.
