为了解当地主要当家品种不同年份对稻瘟病菌抗病力的强度、面积增减对稻瘟病菌抗病力的影响,从而合理地抓好品种布局,以控制、减轻稻瘟病的为害.我站于1982年早季开始,布置建宁、大田、清流、泰宁、尤溪、永安、沙县、宁化、将乐、三元、梅列等县(区)测报站,对77—175、7944、71—20、科辐红2号、红云33等五个主要当家品种穗瘟发病率、损失率进行调查,为品种布局提供抗性依据.现将调查情况整理如下:
In order to understand the influence of the strength and area increase and decrease on the resistance of Magnaporthe oryzae to Magnaporthe oryzae in different years in different regions of the country, to reasonably grasp the variety layout to control and reduce the damage of Magnaporthe oryzae In the early morning of 1982, a number of counties (districts) such as Jianning, Daejeon, Qingliu, Taining, Youxi, Yong’an, Shaxian, Ninghua, Jiangle, , 71-20, Kekehong 2, Hongyun 33 and other five major varieties of head blast incidence and loss rate survey to provide the basis for the variety of the layout of the layout of the investigation are summarized as follows:
