【摘要】：以云烟87为研究对象,探索复合微生物菌剂(EM菌剂)配施腐殖酸钾对植烟土壤改良及烤烟经济效益的影响。结果表明,EM菌剂配施腐殖酸钾显著增加了土壤中微生物数量,增强土壤酶活性,提高土壤养分含量,并且增加了土壤pH值,效果优于两者单施。单施EM菌剂和腐殖酸钾均显著提高了烟叶产量以及经济效益,但两者配施效果更佳。
[Abstract]:In this paper, Yunyan 87 was used as the research object to explore the effects of compound microbial agent EM) and potassium humic acid on soil improvement and economic benefit of flue-cured tobacco. The results showed that the application of humic acid potassium in combination with EM bacteria significantly increased the number of microbes in soil, enhanced soil enzyme activity, increased soil nutrient content, and increased soil pH value, and the effect was better than that of both alone. The application of EM and potassium humate significantly increased the yield and economic benefit of tobacco, but the combination of EM and potassium humate was better.
