种植抗病丰产良种、合理栽培和化学防治是当前解决小麦锈病问题的三个重要方面。尤以前二项现实意义更大,而且需要在小麦播种以前就要作好安排。 一、种植抗锈良种是防治小麦锈病的根本措施 种植抗病丰产良种防治小麦锈病,国内外已有很多经验。但也还存在着一些问题。最主要的是品种抗锈性丧失的问题。大家都知道,碧蚂1号,从1956年起,巳在大面积上“丧失”了抗锈性。据今年了解南大2419在四川盆地和汉中盆地一带也开始普遍感染了条锈病。此外,还有不少抗锈良种如:矮立多、中农28、玉皮、甘肃96号、农大183等也
Planting disease-resistant varieties of high yield, rational cultivation and chemical control are the three important aspects to solve the problem of wheat rust. In particular, the first two are of greater practical significance and require that arrangements be made before wheat is sown. First, the planting of anti-rust seeds is the fundamental measure against wheat rust Planting disease-resistant varieties of wheat rust prevention and control at home and abroad have a lot of experience. But there are still some problems. The main problem is the loss of varieties of rust. As we all know, Pitt No. 1, since 1956, has “lost” rust resistance over a large area. According to this year’s understanding, Nantah 2419 has also begun to be commonly infected with stripe rust in the Sichuan Basin and the Hanzhong Basin. In addition, there are many anti-rust seeds such as: Liduo, Zhongnong 28, jade, Gansu 96, NTU 183 also
