摘要: 基于对浙江省典型规模养猪场3种不同生长阶段猪(保育猪、育肥猪和母猪)在2007年秋冬季和2008年春夏季的产排污调查,测算了3种猪的产排污系数和猪场的年产排污量,并据此及浙江省2007年各种畜禽存栏量普查结果,估算了浙江省畜禽养殖业年粪便农田施用量.结果表明: 2007年,浙江省畜禽养殖业年粪便农田施用量为2106.8×104 t,其中,总氮13.57×104 t、总磷6.7×104 t、铜0.11×104 t、锌0.20×104 t;全省耕地猪粪当量负荷量为16.66 t·hm-2·a-1,负荷量警报值平均为0.37.浙江省部分地区的畜禽粪便施用量已超出了农田负荷量,对周围环境构成了潜在威胁.

Abstract: Based on the investigation of pollutant production and discharge from a typical scale pig farm in Zhejiang Province at three pig growth stages (piglets, fattening pigs, and sows) in the autumn and winter 2007 and the spring and summer 2008, the coefficients of pollutant production and discharge from the pigs as well as the total annual pollutant production and discharge from the farm were estimated. In the meantime, the annual application amount of animal manure to the farmlands in Zhejiang Province was estimated by using these coefficients and the livestock and poultry inventories in Zhejiang Province in 2007. It was estimated that the total amount of applied animal manure in the Province in 2007 was 2106.8×104 t·a-1, containing 13.57×104 t·a-1 of N, 6.7×104 t·a-1 of P, 0.11×104 t·a-1 of Cu, and 0.20×104 t·a-1 of Zn. The pig-manure equivalent farmland carrying capacity in the Province was 16.66 t·hm-2·a-1, and the average alarm limit was 0.37. The application of animal manure in some areas of Zhejiang Province had exceeded the alarm limit for the land carrying capacity, and made a potential environmental threat.
