摘　　要：在田间人工接种条件下，研究了氮肥、磷肥和灌水对小麦黑胚病（Bipolarissorokiniana）发生的影响。结果表明，氮肥（尿素）和氮肥＋磷肥（过磷酸钙）追施可降低小麦黑胚病粒率，单施磷肥的作用不明显；少2次灌水对黑脏病发生亦没有明显影响。因此，建议生产上增施氮肥以减轻小麦黑胚病发生和危害。The effects of nitrogen(urea)and phosphorus (super phosphate)on dark kernel of wheat (Bipolaris sorokiniana ) was studied. The results showed that N and NP decreased the severity of the disease,P had no effect. Meanwhile,lacking of two times of irrigating showed no effect on the disease
