【摘要】 试验以播种前2、3、4、6 d分别用甲基硫菌灵和硫酸链霉素对马铃薯种薯切薯后干拌、湿拌,以不拌种做对照,探讨干拌、湿拌以及拌种后间隔期对马铃薯早疫病、晚疫病田间病薯率及产量的影响。结果显示,药剂的不同拌种方式均能在一定程度上增加马铃薯的产量,干拌的拌种方式增产效果最好,与对照相比平均增产38.05%,播种前2 d切薯并采用药剂干拌对减少田间病薯率效果最明显。更多还原

【Abstract】 In order to understand the effect of dry mixing,wet mixing and time lag after seed dressing on the infection rate of potato early blight and late blight,and the potato yield,the experiment chose thiophanate methyl and streptomycin sulfate to dress seed pieces and put aside the seed pieces dressed in the manner of dry mixing and wet mixing 2,3,4 and 6 days before planting,with no dressing as control.Both ways of seed dressing increased the yield of potato to some extent.The dry mixing produced the best effect,increasing yield by 38.05% compared with the control,on an average.Dressing the seed pieces two days before planting had the evident effect on the reduction in the diseased potato tubers in the field.更多还原
