青稞黑穗病(散黑穗病、坚黑穗病)是当地青稞上的一种主要病害,一般发病率3％左右,过去推广2％石灰水浸种防治方法,虽然防病效果是肯定的,但浸种容器难以解决,防治面积和防病效果受到了一定的限制。托布津拌种方法简便,但用在青稞上防病效果如何,本试验为推广提供依据。一、材料 1.供试品种,昌青8号(原为农家品种),该品种对黑穗病抗性较差。 Barley smut (scattered smut, Jian smut) is a major disease on the local barley, the general incidence of about 3%, in the past to promote 2% limewater soaking prevention and control methods, although the prevention effect is affirmative, However, soaking seed containers difficult to solve, prevention and control of disease area and affected by certain restrictions. Topsoe seed dressing method is simple, but the effect of preventing diseases on the barley, the test provides the basis for the promotion. First, the material 1. The test varieties, Changqing 8 (formerly a farmhouse variety), the variety of smut resistance is poor.
