作者针对水稻抗瘟育种中“旱地稻瘟病圃”易受气候生态等条件的影响,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,采用活体病株持续接种,和人为小气候控制等措施,完善成一套发病系数高且稳定、方法简便实用、病圃容量大、鉴定结果可靠性强的综合技术措施。在连续几年试验中鉴定筛选出一批利用价值较高的种质资源和抗病性较好的系统材料。 In response to the conditions of climate and ecology in paddy field in paddy field, the stability of the disease and the safety of the disease can be caused during the inter-year. Improve the past spray inoculation or the use of ward natural induction method, the use of persistent inoculation of the inoculum, and anthropogenic climate control and other measures to improve into a set of high and stable incidence coefficient, the method is simple and practical, nursery capacity, the reliability of the identification results Comprehensive technical measures. In a few years of experiments, we identified and screened a batch of systematic materials with high utilization value of germplasm resources and good disease resistance.
