随着我国规模化养猪场迅速发展,排放的粪尿污水不断增加,导致严重的环境污染,成为规模化养猪可持续发展亟待解决的问题。种养结合是污水最佳处理利用途径。规模化养猪场污水在农田特别是在农场经营条件下应用的技术缺少系统研究,本研究通过田间试验探讨实现小麦高产优质高效的污水利用技术,为规模化养猪场-农田种植循环农业模式的应用提供技术支持。试验所用污水为养猪场粪尿和冲洗废水经过充分发酵后的污水,污水含全氮1 000 mg.L~(-1)、速效氮540 mg.L~(-1)、速效磷779 mg.L~(-1)。在常规基施化肥基础上,设计小麦越冬期施入0 m~3.hm~(-2)、30 m~3.hm~(-2)、60 m~3.hm~(-2)、90 m~3.hm~(-2)、12...

With the rapid development of China＇s large-scale pig farms,increasing manure and sewage discharge is causing severe environmental pollution that in turn threatens the sustainable development of large-scale pig farming.The utilization of sewage,a kind source of nutrient,by combined pig farming with cropping is the best solution to this problem.As sewage utilization in farmlands lacked systematic research,a field experiment was conducted to study sewage effect on yield and quality of wheat.The results of the study could provide the scientific b...
