| 摘 要： | 为探讨不同类型芽孢杆菌菌剂对甘薯产量和品质的影响，以苏薯16为试验材料进行田间小区试验，设置4种芽孢杆菌菌剂和对照（CK）处理，研究芽孢杆菌菌剂对甘薯不同时期产量及品质的影响。结果表明，在常规施肥基础上，施加4种不同类型芽孢杆菌菌剂均能增加甘薯产量和品质。在移栽后142d，枯草芽孢杆菌处理下甘薯的增产幅度最大，4种芽孢杆菌菌剂处理相比CK处理增产幅度为4.6%～25.4%；在整个生长期，甘薯淀粉积累量呈先增加后减少的趋势，在移栽后113d淀粉积累量达到最大值，4种菌剂处理相比CK处理增幅为2.9%～16.4%，增幅最大的是甲基营养型芽孢杆菌；甘薯可溶性糖积累量呈先减少后增加变化趋势，并在移栽后142d达到最大值，4种菌剂处理相比CK处理增幅为3.2%～34.2%，其中解淀粉芽孢杆菌处理最显著。甘薯胡萝卜素积累量与粗蛋白含量变化趋势基本一致，均呈先增后减的变化，并在移栽后90d达到最大值，在移栽后142d其增幅分别为6.1%～29.5%和2.8%～14.5%，其中解淀粉芽孢杆菌处理最显著。通过主成分分析综合评价得出，施加解淀粉芽孢杆菌对甘薯产量及品质的促进效果最佳。

| Abstract: | In order to investigate the effects of different types of Bacillus species on yield and quality of sweet potato, a field experiment was conducted with Sushu 16 as the test material and four types of Bacillus fungicides and control (CK) treatments were set. The results showed that the application of four different Bacillus species on the basis of conventional fertilization could increase the yield and quality of sweet potato. The yield increase of sweet potato was the largest under Bacillus subtilis treatment after planting 142 days, and the yield of the four Bacillus treatments were increased by 4.6%-25.4% compared with CK treatment. The starch accumulation of sweet potato showed a trend of increasing and then decreasing throughout the growing period, and the starch accumulation reached the maximum after planting 113 days, and the four Bacillus treatments were increased by 2.9%-16.4% compared with CK treatment, the largest increase was the treat with methylotrophic Bacillus. The soluble sugar accumulation of sweet potato showed a trend of decreasing and then increasing, and reached the maximum after planting 142 days, the four bacterial species were increased by 3.2%-34.2% compared with CK treatment, the treatment of Bacillus amyloliquefaciens was the most significant. The trend of sweet potato carotene accumulation were general consistent with crude protein content, showing an increase followed by a decrease, and reached the maximum after planting 90 days, and increased by 6.1%-29.5% and 2.8%-14.5% after planting 142 days, respectively, and the treatment of Bacillus amyloliquefaciens was the most significant. It was concluded that the application of Bacillus amyloliquefaciens had the best effects on the promotion of sweet potato yield and quality by the principal component analysis. |
