微生物土壤改良剂不同施用方法对烟草产质的影响

Effects of Microbial Soil Amendments with Different Application Methods on Yield and Quality of Tobacco

采用随机区组,设计了4个施用方法处理与对照开展小区对比试验,研究抗重茬微生物土壤改良剂最佳施用方法。结果表明,穴施、条施和灌根均能在一定程度上促进烟株生长,对根部病害防治效率达到40%以上,显著提高了单位面积效益,较对照提高5 500元/hm2,烟叶感官质量好。考虑到穴施和灌根等费工较多,增加了烟叶生产成本,故推荐在施肥时与肥料拌匀进行条施,建议其他产区据此做进一步的研究。

Four application methods of microbial soil amendments with randomized block design were carried out to study the best application method of anti-cropping microbial soil amendments.Results showed that the hole fertilization,bar fertilization and irrigating root promoted the growth of tobacco to certain extent.The prevention efficiency for root disease reached above40%.Compared with the control,the unit efficiency was significantly improved for 5 500 yuan/hm^2.The sensory quality of the tobacco was good.Taking labor costs,such as hole fertilizing and irrigating more,increasing the cost of tobacco production into account,it was recommended to stir mixing and adopting bar fertilization in applying fertilizer.The further research is needed in other areas.
