为了研究腐植酸微生物菌剂在连作马铃薯上的应用效果,本研究采用沟施(处理1)及拌种(处理2)两种方法,研究了腐植酸微生物菌剂对连作马铃薯的抗病促生作用。试验结果表明:施用腐植酸微生物菌剂改善了马铃薯连作土壤的基本性状;施用腐植酸微生物菌剂与对照(处理3)相比,有效促进了连作马铃薯的生长发育,提高了马铃薯的保苗率,增强了马铃薯的抗病性;处理1与处理2与对照相比,增产效果显著,分别增产13.54%和17.00%;处理1和处理2间差异不显著。
In order to study the application effect of humic acid microbial inoculation on potato, this study studied the effects of humic acid microbial inoculation effect. The results showed that the application of humic acid microbial inoculant improved the basic characters of continuous cropping potato. Compared with the control (treatment 3), humic acid microbial inoculant effectively promoted the growth and development of continuous cropping potato and increased the seedling protection rate of potato, Enhanced the disease resistance of potato; treatment 1 and treatment 2 compared with the control, the yield was significantly increased, respectively, 13.54% and 17.00% increase; treatment 1 and treatment 2 was no significant difference.
