近年来,新疆小麦上流行的一种细菌性条斑病,已成为小麦的重要病害。1980年以来,我们着重对该病的发生流行规律及防治进行了研究,现将结果简介于下。 一、发生与为害 小麦细菌性条斑病曾于1973、1976、1979年分别在伊犁、昌吉、石河子、博乐等地发生、流行。1980年本病在博乐垦区大发生,发病面积近10万亩(占播种面积53％),小麦减产约180万斤。被害植株,轻者叶片局部发黄,重者叶片上条斑密布,提前枯死;尤其旗叶受害后,光合产物减少,致使抽穗推迟,不孕小穗增加,籽粒皱缩干瘪, In recent years, a bacterial leaf streak endemic to Xinjiang has become an important disease of wheat. Since 1980, we have focused on the prevalence of the disease and prevention and treatment were studied, the results are summarized below. First, the occurrence and harm Wheat bacterial leaf streak was 1973, 1976, 1979, respectively, in Ili, Changji, Shihezi, Bole and other places, the epidemic. In 1980 the disease occurred in the Bole reclamation area, the incidence of nearly 10 acres (accounting for 53% of sown area), wheat yield of about 1.8 million kg. Vicia faba, the leaves of light yellow local yellow, heavy leaves on the block, early dead; especially after the flag leaf damage, decreased photosynthetic products, resulting in postponed heading, spikelets increase in infertility, shriveled shriveled grain,
