锈病是一种发生范围广、为害程度严重、间歇性发生的小麦病害,尤以条锈病发生为甚。因病造成的减产程度,与发病早晚、轻重以及气候条件等有关,特别是小麦后期受害减产更重。我们就此病对少麦剑叶的为害程度与产量损失的关系进行了试验研究。 Rust disease is a wide range of occurrence, serious damage, intermittent occurrence of wheat diseases, especially stripe rust disease is even worse. Due to illness caused by the reduction of production, and the incidence of sooner or later, severity and climatic conditions, etc., especially the late wheat yield more weight loss. We conducted a pilot study on the relationship between the damage degree of wheat leaves and yield loss.
