| 摘 要： | 通过3a试验研究了磁化水膜下滴灌对土壤脱盐效果及对棉花生长发育和产量的影响。结果表明：磁化水能有效的降低土壤含盐量，促进棉花生长发育，提高棉花产量和品质。在0-60cm土层，磁化水的纯脱盐率在20%～30%，同时对土壤中的SO42-、Cl-含量也有明显的降低。磁化水滴灌棉花较对照增产皮棉144.7kg/hm2，可增收2025.8元/hm2，磁化水滴灌促进了棉花的增产增收。

| Abstract: | A three-year experiment was conducted on the cotton growth and effect of decreasing soil salinity by using magnetization water for dripping irrigation under mulching plastic films. Results showed that magnetization water used in the experiment could reduce the soil salinity effectively, and promote the cotton growth and raise cotton yield and quality. At the 0-60 cm soil layer, magnetization water of dripping irrigation could decrease soil salinity rate about 20-30% purely. Simultaneously, the content of SO42- and Cl- in the soil were also decreased evidently. Compared with ordinary water, magnetization water can increase ginned cotton by 144.7 kg/hm2, and raise income by 2025. 8 yuan/hm2. So magnetization water dripping irrigation can increase the cotton production and income. |
