| 摘 要： | 微区试验结果表明:油菜施钾效果受成土母质的影响,施钾效果高低顺序为:花岗岩＞小河冲积物＞红砂岩＞页岩＞Q3＞长江冲积物＞Q2;土壤质地对油菜施钾效果产生明显影响,油菜施钾增产效果与土壤中＞0.02mm的细粒含量成显著正相关,其中与＞0.2 mm的粗粒含量也成正相关,即质地愈粗施钾效果愈好,而粘粒含量愈高则施钾效果愈差.

| Abstract: | The yield responses of rapeseed( Brassica napus L )to potassium application were studied with different soil mother materials in micro-plot trial The results showed that,the increment of rapeseed yield to potassium application was changed with different soil mother materials Soil texture also had inference on the increment of rapeseed yield to potassium application significantly,which the soil was more sandy the increment was higher |
