摘要
新疆棉花面积大，有着丰富的棉籽饼、棉秆资源，将其直接还田后当年可分别增产籽棉15．7％～30％、8．5％～14．6％；可保持和提高土壤养分，是连作棉田土壤有机质来源的重要途径。抓好棉籽饼、棉秆还田和化肥深施，把三者合理地融为一体，是培肥地力，维护棉田土壤肥力，解决大农业条件下有机肥不足的有效措施。
Because of a huge acreage under cotton,there are abundant Resourccs of cotton seed cake and cotton stalk in Xinjiang.Their direct return to soil can increase unginned cotton by 15. 7% ~ 30%, 8.5 ~ 14. 6%, which maintain and improve soil nutrient and is an important sources of soil organic matter for continuous cropping.
