摘　　要：本文分析了农虎禾在贵州不同生态条件下气候、土壤、抗性等方面的适应性。结果表明:它适宜我省海拔1550米以下稻作区种植,最适生态区在450～1250米,比CK增产5.19～47.55％;植株形态和生育期变幅不大,光温反应不甚敏感;各性状CV％变化顺序:穗粒数>穗数>株高>生育期>千粒重,且均低于CK;耐冷烂阴湿等土壤不良环境,比CK增产35.6～39.1％。产量高,抗性强,米质优,食味好,易脱粒,适应性广,是一个适合我省现行耕作水平的糯稻良种。This paper discussed the adaptability of Nonngfuhe to the climate and ecological environments. The results showed that it suited to be planted in the area of altitude below 1550m, specially suited the area at the elevation within 450m to 1250m. Its yield was over 5.13% to 47.55% higher than that of check variety. Change of both plant-type and growth duration was small. The order of CV(%) for various characters were: grains panicle>panicles>plant height>days to growth>1000-grain weight. Nongfuhe was not very sensitive to photoperiod and temperature presented, good enduranee to cold, shade and other soil effectors. Nongfuhe showed high yield, good quality, resis ant to blast of rice, adaptable to the cropping system of Guizhou.
