The results showed that there were no significant differences of celery yields between the treatments under the reduction of fertilization strategy which applied organic and inorganic fertilizers together and the conventional one. Nitrogen use efficiency and the celery Vc content were improved, while the nitrate content in edible parts and soil nitrate accumulation in 0 -100 cm layer were reduced significantly. Under the experimental conditions, with the consideration of yield, economic and environment, the proper pattern of 20% reduction of nitrogen fertilizer with bacteria slag was the best. 【总页数】4页(P55-58) 【作 者】于涛;苏黎;牛世伟;何志刚 【作者单位】辽宁省农业科学院环境资源与农村能源研究所,辽宁沈阳110161;辽宁省农业科学院环境资源与农村能源研究所,辽宁沈阳110161;辽宁省农业科学院环境资源与农村能源研究所,辽宁沈阳110161;辽宁省农业科学院环境资源与农村能源研究所,辽宁沈阳110161 【正文语种】中 文 【中图分类】S147.2;S636.3 【相关文献】 1.有机无机肥料配合施用对设施条件下芹菜产量、品质及硝酸盐淋溶的影响 [J], 高伟;朱静华;李明悦;黄绍文;唐继伟 2.有机肥部分替代化肥与化肥减施对土壤、菜心产量和品质的影响 [J], 黄庆;刘忠珍;刘景业;黄连喜;李翔;魏岚;黄玉芬;陈伟盛 3.连续种植翻压紫云英减施化肥对江西早稻产量、品质及土壤肥力的影响 [J], 王赟;徐昌旭;周国朋;常单娜;高嵩涓;曹卫东 4.化肥减施对大白菜生长、产量和品质的影响 [J], 贾圣青;杨振超;任苗;翁爱群;李瑞;庞启勇;张明科 5.化肥减施对大棚芹菜产量和品质的影响 [J], 高媛;万恩梅;李丹妮;高鹏;王永琦;姚远;江山;张庚龙 因版权原因，仅展示原文概要，查看原文内容请购买 本文来源：https://www.wddqw.com/doc/5ab3f17accc789eb172ded630b1c59eef9c79a55.html
