摘 要:为防控设施菜地土壤次生盐渍化,以云南、上海、江苏、陕西、甘肃、宁夏、山东、河北和辽宁的设施菜地为研究对象,基于土壤盐分积累模型,开展面向次生盐渍化防控的畜禽粪便设施菜地承载力的建模工作;根据各省设施菜地土壤含盐量现状与盐化分级标准,设置对应的土壤含盐量阈值,估算每hm2设施菜地适宜施用畜禽粪肥量与承载力。结果表明:1)9个省份每hm2设施菜地可承载的生猪、奶牛、肉牛、蛋鸡和肉鸡数量分别为8.6~153.7头、0.4~4.1头、0.6~11.4头、8.5~162.5羽和58.8~1107.5羽;2)设施菜地土壤和畜禽粪肥含盐量较高,已经限制了畜禽粪肥还田利用与承载力。建议推广淋洗排盐、暗管排水或深耕技术,以降低土壤盐分残留,从而提升畜禽粪便设施菜地承载力。本研究可为区域种养平衡与土壤障碍因子治理提供参考。To prevent soil secondary salinization in greenhouse vegetable fields,Yunnan,Shanghai,Jiangsu,Shaanxi,Gansu,Ningxia,Shandong,Hebei and Liaoning were considered as our research objects.A model was developed based on the soil salinity accumulation model to assess the bearing capacity of greenhouse vegetable fields and prevent soil secondary salinization.According to the current soil salinity and salinization grading standards of vegetable greenhouses in each province,the corresponding soil salinity thresholds were set to estimate the appropriate manure application per hectare of greenhouse vegetable field and its bearing capacity.The results showed that:1)The greenhouse vegetable field bearing capacity of livestock and poultry manure in the nine provinces ranged from 8.6 to 153.7 pigs equivalent,0.4 to 4.1 dairy cattle equivalent,0.6 to 11.4 beef cattle equivalent,8.5 to 162.5 layers equivalent,and 58.8 to 1107.5 broilers equivalent per hectare,respectively.2)Salt content in vegetable greenhouse soils and animal manure was high,which limited the utilization of animal manure for returning to the fields and greenhouse vegetable field bearing capacity.This study recommended promoting techniques such as leaching,subsurface drainage pipe,and deep tillage to reduce soil salinity and enhance the greenhouse vegetable field’s carrying capacity of livestock and poultry manure.This research provided a basis for balancing regional agriculture and animal husbandry production systems and managing other factors of soil obstacles.
