摘要:

为探究农药残留是否会限制粪肥还田量与畜禽养殖量,本研究以浙江省的稻田为种植业研究对象,以肉鸡和蛋鸡养殖为养殖业研究对象,以吡虫啉为目标农药;根据吡虫啉在种养业间的流动特征,运用物质流分析法、风险商法和土壤环境影响预测法,构建基于吡虫啉生态风险值的鸡粪稻田承载力模型;参考土壤理化参数、土壤和鸡粪中农药残留量、鸡粪排泄量等参数的变异性,运用蒙特卡洛分析法,估算适宜的肉鸡或蛋鸡养殖量变化范围。结果表明,浙江省每公顷稻田短期、中期和长期可承载的肉鸡养殖量分别为38 064~62 793、5 336~15 759和0~1 492羽,蛋鸡养殖量分别为4 996~9 188、715~2 245和0~205羽。若肉鸡粪便和土壤中吡虫啉残留量减少25%,每公顷稻田可承载的肉鸡养殖量可分别相对增加33.3%和8.4%。综合考虑畜禽养殖业发展与农田土壤环境保护需求,建议大力推广农药减量增效技术,降低土壤吡虫啉残留,同时监测畜禽粪便中的农药残留,以促进浙江省种养业的绿色发展。

Abstract:

To investigate whether pesticide residues would limit the amount of manure returned to fields and the quantity of livestock and poultry farming, this study took paddy fields in Zhejiang Province as the research object in crop planting, broiler and laying hens farming as the research objects in animal husbandry, and imidacloprid as the pesticide type for study. According to the flow characteristics of imidacloprid between crop planting and animal husbandry, this study constructed a paddy field carrying capacity model of chicken manure based on the ecological risk value of imidacloprid by using material flow analysis, risk quotient method and soil environmental impact prediction. Considering the variability of parameters such as soil physicochemical parameters, pesticide residues in soil and chicken manure, and chicken manure excretion, the Monte Carlo analysis method was used to estimate the appropriate variation range of broiler or laying hens farming scale. Our results showed that the short-term, medium-term and long-term carrying capacity of broiler breeding per hectare in Zhejiang Province were 38 064-62 793, 5 336-15 759 and 0-1 492 birds, respectively, and those of laying hens breeding were 4 996-9 188, 715-2 245 and 0-205 birds, respectively. If imidacloprid residues in broiler manure and soil decreases by 25%, the carrying capacity of broiler farming per hectare will increase by 33.3% and 8.4%, respectively. Considering the development needs of livestock and poultry farming and the protection of farmland soil environment, it is recommended to actively promote pesticide reduction and efficiency enhancement technologies to reduce imidacloprid residues in soil. Meanwhile, pesticide residues in manure should be monitored to promote the green development of crop planting and animal husbandry in Zhejiang Province.
