本文针对水稻抗病育种中旱地稻瘟病圃易受气候环境等条件的影响，导致年际间发病的稳定性和能否发病的安全性，改进以往喷雾接种或利用病区自然诱发法，采用活体菌株持续接种的方法，通过双圃（活体菌株圃、旱地稻瘟病圃）和小气候控制等技术措施，完善成一套发病系数高、稳定性好、方法简便、病圃容量大，鉴定结果可靠性强的综合技术措施。并在几年研究试验中，鉴定筛选出一批有利用价值的种质资源和有望新品系
In this paper, the resistance of rice blast disease in rice paddy nursery susceptible to climate and environmental conditions, leading to the stability of the inter-year onset and the possibility of onset of safety, improve the past spray vaccination or the use of ward natural induction method, the use of living The continuous inoculation method of strain is improved through a series of technical measures such as dual-nursery (live nursery stock, dryland blast plague nursery) and microclimate control, etc. The method has the advantages of high incidence coefficient, good stability, simple method, large nursery capacity, high reliability of identification result Comprehensive technical measures. And in a few years of research trials, identification of a number of valuable resources and promising germplasm screening new lines
