通过1991,1992两年的调查研究,初步了解了陆良地区稻瘟病的发生发展与农业措施的关系。首先是水稻品种的抗病性有随种植年限的增长而有所减弱的趋势。穗瘟的发生有随氮素化肥用量增加而加重。通过工作,还为稻瘟病发生予测积累了数据,也为抗病品种的合理布局提供决策的参考。 Through the investigation and research in 1991 and 1992, the relationship between the occurrence and development of rice blast and agricultural practices in Luliang region was preliminarily understood. First of all, the resistance of rice cultivars tended to weaken with the increase of planting years. The occurrence of panicle blast increased with the increase of nitrogen fertilizer. Through work, but also for the occurrence of rice blast accumulated data, but also for the rational distribution of resistant varieties provide a reference for decision-making.
