华北平原冬小麦-夏玉米轮作体系秋季一次基施牛粪氮素损失与利用研究
Nitrogen loss and use efficiency of one-time basal application of cattle manure in autumn to a winter wheat-summer maize cropping system on the North China Plain
摘要
Abstract
Cattle manure was applied to a winter wheat-summer maize cropping system on the North China Plain in autumn as a single basal application (MOAA).In order to provide parameters for evaluation of environmental effects of MOAA, experiments employing no fertilizer application and split application of ammonium sulfate (SAAS) and MOAA as N 300 kg/ha were carried out in Ji county, Tianjin City; as N 300 and 450 kg/ha and was also adopted 15N tracer technology in Ling county, Shandong province, to study nitrogen (N) utilization and 15N loss.In the winter wheat-summer maize cropping system, 30％-38％ of the total manure 15N was lost, which did not differ significantly from SAAS 15 N loss.Manure N loss was N 89 kg/ha following N 300 kg/ha manure N application, and N loss sharply increased by 91％ when manure N application increased by 50％.After winter wheat harvest, the amount of soil NO3- -N at 0-80 cm depths in MOAA was N 38 -40 kg/ha in Ling county and N 95 kg/ha in Ji county, and decreased to N 18 -23 and 18 kg/ha after summer maize harvest, respatively; in both instances, the values were lower than those of SAAS.In farmland with long-term application of manure, there were no significant differences in winter wheat and summer maize grain yields between MOAA and SAAS.From an environmental point of view, it is concluded that MOAA is an appropriate application but the amount of N should not exceed N 300 kg/ha.关键词
