| 摘 要： | 进行了施用化肥对稻瘟病发生程度的影响试验,结果表明:不同化肥种类,不同施肥用和不同施肥方式对水稻稻瘟病发生程度有一定的影响.从控制稻瘟病的角度来看,在N:P:K为4:2:1的情况下,施肥纯量为210-240kg/hm2最为适宜,稻瘟病发病程度最轻.施用钾能增强水稻植株抗病性,降低叶稻瘟病的发生程度.从水稻各生育时期施肥比例来看,以基肥:蘖肥:9叶期调解肥:穗(粒)肥为3:3:1:3为宜,稻瘟病发病程度较轻.

| Abstract: | Trial result indicates that different kinds,amounts and ways of fertilization affected occurrence degree of rice blast.Looking ahead, controlling rice blast was in the case of N:P2O5:K2O,4:2:1 is better than others.Under this condition,quantity of fertilization from 210kg.hm-2 to 240kg.hm-2 showed the better,incidence disease was also lower.Fertilization of Potash strengthens the resistance to blast in rice,lightening occurrence degree.Proportion of fertilization to rice at different growth stages,basic fertilizer: tiller fertilizer: mediating fertilizer: granule fertilizer,3:3:1:3 proved better than others,incidence disease was lower than others. |
