磁化水滴灌对棉田土壤脱盐效果及棉花产量的影响
Effects of Drip Irrigation with Magnetized Water on Soil Desalinization in Cotton Field and Cotton Yield
摘要
Abstract
In this study,the effects of drip irrigation with one-time magnetized water or two-time magnetized water and control treatment on soil desalinization in cotton field,cotton plant growth and cotton yield and quality were researched so as to propose a new technology for improving salinized soil.The results showed that magnetized water could be used to effectively desalinize soil under drip irrigation and improve the leaching of Cl-and Na + in soil.Desalination effect of the treatments of two-time water magnetization and one-time water magnetization was significantly higher than that of the control treatment,and that of the treatment of two-time water magnetization of 3 600-2 000 mT was the most optimal.The soil salt content of two-time water magnetization and one-time water magnetization was decreased by 25.5％ and 19.5％ respectively,and that of CK was decreased by only 10.46％.Drip irrigation with magnetized water could be not only used to promote the growth of cotton plant,improve cotton boll branches and increase boll number,but also improve cotton yield and quality,and the cotton yield could be increased by 9.61％-15.32％.关键词
