摘要: 【目的】药食兼用百合为湖南栽培较广的药用植物,其绿色生产是目前百合产业转型升级的要求。养牛场污水直接排放将引发环境污染,但其经无害化处理后是营养丰富的有机肥。采用大田试验考察了养牛场污水在百合绿色生产中的应用效果。【方法】将养牛场污水进行无害化处理后,替代化肥用于百合种植,研究了养牛场污水对百合的农艺性状和产质量及土壤理化性状的影响。【结果】结果表明:在施足有机肥当基肥的基础上,于百合生长旺盛期追施经无害化处理的养牛场污水两次(每次20.2 m3/hm2)比追施化肥处理的百合生长发育情况更好,收获期根长更长,产量达24.1 t/hm2,比等量化肥处理增产12%,且其商品率和总糖含量显著增加。不同处理间土壤的养分含量差异不显著,但施用牛场污水(每次20.2~31.3m3/hm2)处理有利于土壤中微生物量碳氮的增加。【结论】可见,药食兼用百合绿色生产中可施用经前处理的养殖场污水来替代化肥,既充分利用污水中养分,又能提高百合的品质,增加土壤的微生物量。

Abstract: The paper aims to reduce the environmental pollution caused by farm sewage, and explore its resource utilization mode. We studied the effects of cattle farm sewage on lily’s agronomic traits, yield, quality and soil physical and chemical properties by replacing chemical fertilizer for green production of lily after harmless treatment. The results showed that: the twice application of cattle farm sewage (20.2 m3/hm2 every time) as additional fertilizer at lily bud stage replacing chemical fertilizer could promote lily growth, increase the root length, commodity rate, total sugar contents of lily, and enhance lily bulb yield by 12.0% to 24.1 t/hm2; although different additional fertilizer applications had no significant influence on soil physical and chemical properties, the application of cattle farm sewage (20.2-31.3 m3/hm2 every time) could encourage soil microbial carbon and nitrogen. This study indicates that cattle farm sewage after some decontamination treatments can be applied as additional fertilizer during green production of lily for both medicine and food use, which can not only take full advantage of nutrients in cattle farm sewage, but also improve lily’s quality and soil microbial biomass.
