摘要
为了探讨微润灌溉在盐渍化灌区大田作物适用性,以向日葵为研究对象开展微润灌溉试验研究。研究结果表明:微润管埋深为20cm更能促进向日葵的生长,显著提高了向日葵产量和水分利用效率。各生育期向日葵根长密度、根体积密度、根表面积密度微润管埋深为20cm各处理优于埋深为10cm的各处理。微润灌溉各处理较对照产量分别提高了69.4%、50.6%、36.7%、35.8%、57.7%、37.3%、26.2%、10.8%;水分利用效率分别提高了73.6%、79.9%、68.2%、60.4%、61.4%、64%、55.3%、30.9%%。
To investigate the Moistube Irrigation in applicability, salinization irrigation field crops to sunflower as the research object to carry out the micro irrigation experimental study. The results show that the Moistube Irrigation pipe buried deeply 20 cm more can promote the growth of the sunflower, significantly improve the yield and water use efficiency of sunflower. The growth period sun- flower root length density, the density of root volume, root surface area density Moistube Irrigation pipe buried deeply 20 cm each processing is better than buried deeply 10 cm. Embellish of Moistube Irrigation the processing production than control respectively increased by 69. 4%, 50. 6%, 36. 7%, 50. 6%, 57. 7%, 37. 3%, 26. 2%, 37. 3%; Water use efficiency increased by 73. 6%, 79.9%,68. 2% and 79. 9% respectively, 61.4%, 64%, 55.3%, 30. 9%.
