| 摘 要： | 研究了膜下滴灌、低压渗灌和常规淹灌3种灌溉模式土壤速效钾含量.结果表明,在水平方向上,棉花宽行土壤中速效钾含量显著低于窄行;在垂直方向上,钾素均随土层深度的增加总体呈下降趋势.土壤中钾含量丰富,无论在耕层土壤还是深层土壤,速效钾含量均较高.

| Abstract: | The experiments were used for the study on content of available potassium under plastic mulched drip irrigation,flood irrigation and subsurface drip irrigation.The results showed that the content of soil available potassium was higher in wilder row than in narrow row by horizontal;the content of soil available potassium assume decent trend as the depth of soil.No matter surface or subsurface soil available potassium was abundant. |
