| 摘 要： | 麦棉双套使土地长期在满负荷状况下运转,难以得到深耕与休闲。以氮素为主的传统单一施肥方法使土壤理化性质日趋恶化,肥力逐渐下降,不利于夺取麦棉双高产。通过试验,对其培肥技术进行了系统研究。结果表明:合理地施用专用复混肥和专用配合微肥,有利于土壤养分得到以平衡供应;加大生物有机肥施用量,实行小麦高留桩和直接覆盖还田,可使地力得以恢复,麦棉双套双高产。

| Abstract: | The rotation system of cotton and wheat and application of only nitrogen fertil- izer results in soil heavy burden and degradation of soil properties.A series of techniques including special fertilizer containing multielement nutrients,microbial fertilizer and straw addition,were used in this region.It was found that soil could supply nutrient in balance and be recovered from the continuous cropping.The high yield of both cotton and wheat could be obtained with application of the techniques. |
