轮作是防治玉米丝黑穗病的根本性措施。近年来由于玉米种植面积扩大,及部分实行间种,难于轮作倒茬。因此,成株期拔除病株就成为消除越冬菌源补充轮作不足的有效措施之一。但是过去由于方法过繁,在生产上很难应用。为改进这一措施,在1976年小型观察的基础上,沈阳农学院和昌图县各有关单位协作,在生产现场试点,对原方法进行了总结提高,并在昌图县和吉林省抚松县较大面积上得到推广,初步取得成效。现将几年来的工作经验和体会作一初步小结,供有关部门参考。
Rotation is a fundamental measure to prevent and treat maize smut. In recent years due to the expansion of corn acreage, and part of the implementation of inter-species, difficult to crop rotation. Therefore, the removal of diseased plants at adult stage has become one of the effective measures to eliminate insufficient supply of overwintering bacterial sources. But in the past because of the complicated method, it is hard to apply in production. In order to improve this measure, on the basis of small-scale observation in 1976, Shenyang Agricultural College cooperated with all relevant units in Changtu County to conduct pilot tests on the production site and summarized and improved the original methods. In addition, in Changtu County and Fusong County, Jilin Province, A large area to be promoted, the initial success. Now years of work experience and experience make a preliminary summary for the relevant departments for reference.
