摘　　要：羟锈宁与增产菌混合拌种不但对甜菜黑脚病有防效.而且也有增产增糖作用。小区试验和多点示范看出,羟锈宁与增产菌混合拌种对黑脚病防治效果达71.5％～76.2％;根产量较对照高10.2％～16.0％;含糖率较对照高0.80～1.00度;产糖量较对照高15.1％～27.3％。在使用过程中增产菌不能代替肥料.只有在水肥充足情况下.才能发挥增产潜力.羟锈宁因用量小.拌种定要均匀,以免发生药害。It not only had effective controlled to sugarbeet blackleg but also had the role in increasing yield and sugar content by seed dressing with Qiang Xiu Ning and Zeng Chan Jun mixed. It shown that the controlled results were reached 71.5-76.2% from plot tests and demonstration in many sites.Root yield were higher 10.2-16.0% than check, sugar content 0 8-1.0%, sugan yield 15.1-27,3% higher. The Zeng Chan Jun could not replace the f rtilizers during applications, it could bri g the potential of increas ng production into full play only under the condition of warer and fertilizers were very sufficient. Because the application dosage of Qiang Xiu Ning are very low, so the seed dressing must be uniform for anti-chemical damaged to sugar beet.
