摘    要:通过小区试验,研究了秸秆机械化还田和秸秆不还田条件下,不同施肥方案对土壤含水率、土壤中的NO-3—N、速效磷、速效钾及有机质的影响。得出了符合小麦生长需肥要求的施肥方案。在此基础上进行了大面积大田试验,确认了机械化秸秆还田的增产作用及施肥方案的科学性,并对增产机理进行了探讨。

关 键 词:农业机械化    秸秆还田    施肥技术    动态研究

Abstract:The influence of the various manure schedules on the soil moisture, NO-3-N, P, K, and organic matter in the soil with returning stalks into the soil and without returning stralks into the soil is studied. The effective manure schedule that meets the requirement of wheat growth is obtained from the tests in small block fields. Extensive field tests were then carried out and the positive influence of the mechanized returning stralks into the soil on the yield and the effectiveness of manure schedule were proved. Moreover, the yield increasing mechanism by the mechanized returning stralks into the soil was discussed.
Keywords:farm mechanization  returning stalks into soil  manure applying techniques  dynamic research
