摘  要：
采用田间小区试验方法,在自然降雨条件下,对花生地施以不同量的猪粪,结合花生对氮、磷的吸收利用状况、径流养分的流失量和花生产量,研究花生地对猪粪的最大负荷量和土壤承载力。结果表明:花生地可以有效消纳猪粪,在保证经济效益和生态环境效益的同时,猪粪处理量以9 903 kg/hm2处理(CP2处理)的效果最好;施肥量低于CP2处理的花生产量低,高于CP2水平的花生增产效果不明显,并且有机肥的利用率低,流失率高,对环境的二次污染风险加大;花生地对猪的承载力为30.56头/hm2。

摘  要：
The maximum absorptive capacity of peanut land on pig-manure in subtropical areas was determined through field plot experiments, which were carried out at the background of natural rainfall and different fertilization level of pig-manure. Results showed that the peanut land could effectively absorb pig manure. Treatment of 9 903 kg/hm2 pig manure utilization(CP2 level) could gain the best result on the consideration of ecological and economic benefits. The peanut yield would decrease when fertilizing amount was lower than this level. However, yield did not increase remarkably when the fertilization was higher than the level. Above this fertilization level, the higher the pig manure fertilized, the lower its utilization rate would be, which would result in higher nutrient loss and increase the risk of secondary pollution to environment. One hectare peanut land could bear 30.56 pigs at most every season.
