1990年我县小麦收获面积59.6万亩,主要品种有豫麦11(原许06)、陕农7859、豫麦13(原郑州891)、郑州871、冀麦5418、西安8号、西安9号等。这些品种虽然高产,但对条锈、秆锈、白粉病程度不同的感病,加上越冬菌源量大(冬前调查白粉病病田率85.2%、病点率37.84%、病叶率1.1%已形成中心病团;锈病病田率21%、病点率4.7%
In 1990, the county harvested wheat area of 596000 mu, the main varieties are Yumai 11 (formerly Xu 06), Shaanxi 7859, Yumai 13 (formerly Zhengzhou 891), Zhengzhou 871, Ji Mai 5418, Xian 8, Xi’an 9 Wait. Although the high yield of these varieties, but the stripe rust, stalk rust, powdery mildew different degree of susceptibility, coupled with overwintering bacteria source (survey of powdery mildew disease field before winter 85.2%, disease point rate 37.84%, diseased leaf rate 1.1 % Has formed a center disease group; rust disease rate of 21%, disease rate of 4.7%
