摘要
为规范有机肥羊粪在烟田的施用技术,试验设置了有机肥羊粪不同用量和不同施用方式,研究其对土壤理化性质、土壤微生物数量、烟株农艺性状和烟叶经济效益的影响。结果显示,施用有机肥羊粪后,土壤理化性质得到改善,烟株长势变好,土壤微生物数量和烟叶经济效益增加;与对照相比,施用有机肥羊粪3000 kg/hm2配合70%条施+30%穴施时,土壤容重下降7.91%,土壤含水率升高21.31%,土壤碱解氮和有效磷含量分别增加8.37%和12.68%,溶解性有机碳含量增加111.54%,细菌/真菌和放线菌/真菌分别升高52.73倍和119.61倍,烟叶化学成分协调性增强,烟叶产值和上等烟比例分别增加35.84%和37.01%。由此可知,施用有机肥羊粪3000 kg/hm2配合70%条施+30%穴施是适合豫西烟区烟叶种植的一种有效措施。
To improve technology of sheep dung application in tobacco planting fields,effects of different treatments on soil properties,microbial amount,tobacco agronomy and economic performance were studied.The results showed that soil properties and growing condition of tobacco improved,and microbial amount and economic performance increased after sheep dung applying.Effects of sheep dung applying 3000 kg/hm2 and 70%band application and 30%hole fertilization were great,compared to contrast treatment,soil bulk density decreased 7.91%,soil moisture,available nitrogen,available phosphorus,dissolved organic carbon content,ratio of bacteria and fungi and ratio of actinomycetes and fungi,production value and supper tobacco rate increased 21.31%,8.37%,12.68%,111.54%,52.73 times,119.61 times,35.84%and 37.01%,respectively.Above all,the method of sheep dung applying 3000 kg/hm2 and 70%band application and 30%hole fertilization was an effective measure and suitable to tobacco planting in western Henan tobacco soil.
