Chinese. 2008年和2009年连续两年在辽宁省东港市稻区利用3个感稻曲病品种进行田间水稻不同栽培方式对稻曲病发生程度的影响试验。不同施肥方式试验结果表明：单位面积总氮肥量越大，稻曲病发生越重。在施肥总量相同的情况下，在水稻生长后期（穗肥）氮肥量增大有利稻曲病发生。不同播期、插秧期试验表明在试验条件下水稻播期、插秧期偏后，稻曲病发生有加重的趋势。不同插秧密度试验结果显示，水稻插秧密度越大，稻曲病发生相对越重。[著者文摘]

The effects of different rice cultivation modes on the occurrence degree of the rice false smut were studied in 3 species sensitive to Ustilaginoidea virens in the rice fields of Donggang City in Liaoning from 2008 to 2009. The results indicated that rice false smut occurred more heavily when more total nitrogen per hectare existed. Increasing nitrogen was benefit to the occurrence of rice false smut during the late rice growth period in the case of equal amount of nitrogen was fertilized. Tests during different sowing and planting periods showed that false smut of rice occurred more heavily when sowing and planting periods was late. Tests on different planting density demonstrated that rice false smut occurred more heavily when a higher planting density was present.[著者文摘]
