１９８８～１９９３年在灌漠土上进行定位试验。结果表明，６季作物总产量顺序为：单施ＮＰ化肥有机肥与ＮＰ肥配施（１∶０８）＞绿肥与Ｐ肥、厩肥与Ｐ肥配施＞无肥区＞麦秸直接还田与Ｐ肥配施。有机肥与Ｐ肥、有机肥与ＮＰ肥配施使土壤有机质由１６３５ｇ／ｋｇ分别提高到１８７～１９５ｋｇ和１７７～１９３ｇ／ｋｇ，而且对土壤物理性状也有良好的影响。单施ＮＰ肥仅能使土壤有机质和全氮保持平衡，但Ｐ、Ｋ含量显著下降。 1988-1993 in the desert soil for positioning test. The results showed that the total crop yields of six seasons were as follows: application of NP fertilizer alone and NP fertilizer application (1:08)> green manure and P fertilizer, manure and P fertilizer application> no fertilizer zone> wheat straw direct Field and P fertilizer facilities. Combined application of organic fertilizer and P fertilizer, organic fertilizer and NP fertilizer increased soil organic matter from 1635g / kg to 187 ~ 195kg and 177 ~ 193g / kg respectively, and also had good soil physical properties Impact. Applying NP fertilizer alone can only balance soil organic matter and total nitrogen, but P and K contents decreased significantly.
