摘　　要：探索在花生重度空秕田施用钙镁硫配方肥效果,结果表明:每667 m2施钙镁硫配方肥100 kg处理的花生干荚果产量250.4 kg,比不施钙镁硫配方肥处理增产140.8 kg,花生空秕率为4.4%,对降低花生空秕率的效果最佳。Effects of applying calcium, magnesium and sulfur formulated fertilizer to the peanut field with severe empty shell pods were studied. The results showed that, the treatment applying 100 kg/667 m2（ 1500 kg/hm2） calcium, magnesium and sulfur formulated fertilizer had the best effect on increasing the output of dry-pod of peanut, the output was 250.4 kg/667 m2 （3 756 kg/hm2）. To compare with the control that didn＇t apply formulated fertilizer, the output of dry-pod increased byl40. 8 kg/667 m2（2112 kg/hm2） , and the sterile grain rate was significantly decreased down to 4.4%.
