摘要
在定西市半干旱区马铃薯连作田进行了新型生防菌药效试验。结果表明,该生防菌改善了连作马铃薯植株根际土壤微生物的种群结构,有效促进了植株生长,提高了马铃薯产量和薯块商品性,具有较好的促生防病效果,在生产中具有一定的推广价值。
The efficacy trials of a new biocontrol agents on continuous cropping potato were carried out in semi-arid region of Dingxi.The results showed that the biocontrol agents has a good effect on continuous cropping potato,it can improve the microbial community structure in root zone soil,promote the plant growth,improve potato yield and tuber commodity,and it has a certain application value in the production.
