| 中文摘要: |
| 通过秸秆覆盖全程节水对小麦病害发生影响调查,发现其主要病害有:小麦条锈病(Puccinia striiformis West)、小麦白粉病[Blumeria graminis(DC.) Speer]和小麦散黑穗病[Ustalago tritici(Pers)Jens.],免耕和秸秆覆盖处理对这3种病害的发生几乎没有影响;随冬季灌水量的增加,小麦条锈病发病减轻,小麦散黑穗病发病加重,对小麦白粉病影响不大。 |
| 英文摘要: |
| The main diseases are Puccinia striiformis West., Blumeria graminis(DC.) Speer and Ustalago tritici (Pers) Jens. based on the investigations in this experimental field. The disease prevalence and disease degree decreased in the proper order in almost all experimental fields. Free from ploughing and wheat straw covering did not influence these diseases. With increase of irrigation, P. striiformis West lighten and U. tritici (Pers) Jens. increased, while B. grami-nis(DC.) Speer did not change. |
