我们以84—167为供试水稻品种,分别接种纹枯病菌和白叶枯病菌,于网室中进行了盆栽试验。试验设稀土1、稀土2与对照三个处理,6次重复。结果表明: 两稀土处理均能提高水稻对纹枯病与白叶枯病的耐性。其中接种纹枯病的,稀土1、稀土2处理的发病株率依次为43.4%与41.7%,分别比对照的 We took 84-167 as tested rice varieties, were inoculated with Rhizoctonia solani and Xanthomonas oryzae, and pot experiments were carried out in the net room. Experimental set rare earth 1, rare earth 2 and control three treatment, 6 times repeated. The results showed that both rare earth treatments could improve rice resistance to sheath blight and bacterial leaf blight. Inoculation with sheath blight, rare earth 1, rare earth 2 treatment of the incidence rate of 43.4% and 41.7%, respectively, than the control
