通过2007～2009年3年对棉花生长发育、棉花产量及品质的数据分析,探讨了海冰水灌溉及海冰水施加聚丙烯酰胺(PAM)的灌溉模式对棉花生长发育、产量及品质的影响,并筛选了海冰水施加PAM时的高效施肥方式。发现海冰水比井水更能促进棉花的生长发育及品质、产量的提高,海冰水施加PAM的灌溉方式显著优于其它3种灌溉模式,PAM的作用在开荒耕种的第一年更为突出。海冰水施加PAM时,无机肥石膏配施的施肥方式对棉花生长发育、产量的作用为最佳,4种施肥方式对棉花品质各项指标的影响并无明显差异。矿化度为3 g/L的海冰水取代井水灌溉棉花盐碱地,不但能增收,还能有效缓解当地日益紧缺的淡水资源。海冰水灌溉可望成为棉花盐碱地新的有效灌溉模式。
Based on the data of cotton growth and cotton yield and quality from 2007 to 2009, the effects of sea ice water irrigation and polyacrylamide (PAM) irrigation mode on cotton growth and development, yield and quality were discussed. , And screened the efficient application of sea ice when applying PAM. It is found that sea ice is more effective than well water in promoting the growth, quality and yield of cotton. The application of PAM in sea ice water is significantly better than the other three irrigation modes. The role of PAM in the first year of wasteland cultivation is more prominent. When PAM was applied in sea ice water, the application of inorganic fertilizer combined with gypsum had the best effect on the growth and yield of cotton. The effects of four fertilization methods on the indexes of cotton quality were not significantly different. Sea ice water with a salinity of 3 g / L replaces well water to irrigate cotton and saline soil, which can not only increase income but also effectively alleviate the increasingly scarce freshwater resources in the area. Sea ice water irrigation is expected to become a new effective irrigation mode for cotton salinization.
