摘要
利用土壤胶体的带电性和同晶替代理论,研制了双螯合盐碱地改良剂,并在中度盐碱地种植的棉花上开展了田间应用试验。试验设2个处理,每个处理重复3次。结果表明:滴灌双螯合盐碱地改良剂处理与对照处理的土壤水溶性盐分含量较试验前分别降低了55.88%和23.53%,土壤pH由试验前的8.45分别降至7.63、8.19;双螯合盐碱地改良剂对棉花生长发育具有明显的促进作用,与对照处理相比,株高增加2.0 cm,茎粗增加0.25 cm,单株结铃数增加0.6个,单铃质量增加0.39 g,保苗率增加4.7%,皮棉产量增幅23.92%。双螯合盐碱地改良剂对改善盐碱地土壤的酸碱度和可溶性盐分含量具有较显著的作用,同时可促进棉花生长发育,增产效果良好。
Based on the charge of soil colloid and isomorphic substitution theory,a double chelating saline alkali soil conditioner is developed and further field application experiment is carried out on cotton planted in moderate saline alkali soil.Two treatments are set in the experiment and each treatment is repeated for 3 times.The results show that the soil water-soluble salt content of drip irrigation double chelating saline alkali soil conditioner treatment and control treatment decreased by 55.88%and 23.53%respectively and the soil pH decreased from 8.45 to 7.63 and 8.19 respectively.Compared with the control treatment,the plant height increased by 2.0 cm,the stem diameter increased by 0.25 cm,the number of bolls per plant increased by 0.6,the weight of single boll increased by 0.39 g,the seedling preservation rate increased by 4.7%and the lint yield increased by 23.92%.Double chelating saline alkali soil conditioner has a significant effect on improving the pH and soluble salt content of saline alkali soil,and can promote the growth and development of cotton with good yield increasing effect.
