引言近几年来的水稻栽培,由于栽插机械化的不断发展,与过去的栽培方式有很大不问,因此水稻纹枯病的发病情况也发生了很大的变化。对病害防治同水稻栽培一样,要求进一步趋向省力,农药的用量也应尽可能做到少用。为此,我们以重新估量全年一次用药的防治适期为目的,参与了1977年九州病虫防除推广协会联合试验、1978年日本植物防疫协会特别委托全国联合试验,以及1979年九州病虫防除推进协会进行联合试验。现将宫崎县综合农业试验场三年试验结果摘要报导,以供参考。
Introduction Rice cultivation in recent years due to the continuous development of planting mechanization, and the past cultivation methods are very different, so the incidence of rice sheath blight also undergone great changes. Disease prevention and control the same with rice cultivation, requiring further efforts to conserve energy, the amount of pesticides should be used as little as possible. To this end, we have participated in the joint trial of the Kyushu Pest Management Association in 1977 for the purpose of reevaluating the annual control of pesticides. In 1978, Japan’s Association for Plant Disease Prevention specially commissioned a national joint trial and the 1979 Kyushu pest and disease control Promote association to carry out joint test. Now Miyazaki comprehensive agricultural experimental field three years trial results summary report for reference.
