近年来,关于营养条件能影响作物的抗病力,已引起广泛的注意。江苏扬州地区以往秋播兰麦(小麦、大麦、元麦)多以粗肥为主,不能满足三麦苗期生长发育的需要。自推广了化肥底施的措施后,秋播三麦基肥已由过去单纯以粗肥和迟效肥为主,变为粗精搭配,迟速结合,改善了三麦苗期的营养状况,不仅麦苗生长健壮,而且肥效可持续到后期,增产效果显著。针对这一情况,我们自1981—1983年进行了不同肥料营养条件对提高大麦抗黄花叶病能力的试验研究,现将初步结果报道如下。
In recent years, extensive attention has been paid on the ability of crops to affect their disease resistance due to their nutritional conditions. In the past years, the Yangzhou area of Yangzhou City, Jiangsu Province, mainly used crude fat mainly for wheat, barley and wheat, which could not meet the needs of the growth and development of the three wheat seedlings. Since the promotion of fertilizer at the end of the measures, the autumn sowing three wheat base fertilizer from the past purely crude fat and slow-acting fertilizer, into a rough fine collocation, combined with late speed to improve the nutritional status of the three wheat seedlings, not only wheat seedlings Grow robust, and fertilizer sustainable to the late, a significant increase in yield. In response to this situation, we conducted from 1981 to 1983 different fertilizer and nutrient conditions to improve the resistance of barley yellow mosaic test, the preliminary results are reported below.
