Effects of the Microbial Organic Fertilizer on the Flue-cured Tobacco Growth and Development in Southern Henan

[目的]研究微生物有机肥对豫南烤烟大田生长发育的影响。[方法]进行大田肥效对比试验。[结果]结果表明,微生物有机肥能够有效提高烟株根系活力,促进根系生长发育;烟株大田长势及各项农艺性状明显改善;原烟产量、产值和上等烟比例显著提高。[结论]豫南烟区以施用常规无机肥配合450 kg/hm2微生物有机肥效果最好。

[ Objective] The impact of microbial organic fertilizer on the flue-cured tobacco growth and development in southern Henan was studied. [ Method] The efficiency of the fertilizer on the flue-cured tobacco was compared. [ Results] The results showed that the microbial organic fertilizer could effectively raise the root vigor of tobacco plant and promote root growth and development. The tobacco agronomic traits could be significantly improved. The production, output value and the proportion of the first-class leaf could be significantly raised. [ Conclusion] The application amount of organic manure of 450 kg/hm^2 was the best amount in tobacco-growing area of Henan Province based on the conventional inorganic fertilizer.
