Abstract

Abstract:

Conservation tillage and organic fertilizer application are one of the effective solutions to alleviate ecological vulnerability in dry farming areas of the Loess Plateau.Reasonable tillage and fertilization measures are of great significance for the realization of two crops a year in the arid area of central Shanxi.The dry farmland in the Loess Plateau was taken as the research object,and the split-plot experimental design was adopted,the main area was three tillage methods (deep tillage (DT),deep loosening (SS),no tillage (NT)),and the sub-area was four fertilization levels (No fertilizer control (CK),full chemical fertilizer (CF),50% chemical fertilizer+50% organic fertilizer (OF),full organic fertilizer (OM)).The changes of soil bulk density,available nutrients and annual yield of wheat and maize under different tillage and fertilization methods were explored.The results showed that in 0-20 cm the soil bulk density of SS and NT treatments were lower than that of DT treatment after organic fertilizer application.The soil bulk density of SS+OF treatment was 1.13 g/cm³,which was significantly lower than that of DT+OF treatment in wheat season.In the whole annual rotation system,the soil mass water content of NT+OM treatment was the highest,which was 7.88 percent point higher than that of other fertilization treatments,and the three-phase ratio of soil under SS+OM treatment was more ideal,and the deviation value of three phase was low.Under the three tillage methods,the content of available nitrogen and available phosphorus generally showed the trend of OM>OF>CF>CK,and the content of available potassium was significantly related to the fertilization method,which was the highest under the CF treatment.The application of organic manure in maize season significantly increased the fresh ear yield of maize compared with a single application of chemical fertilizer,but the difference between them was not significant.The annual yield of wheat and maize under SS+OM treatment was the highest,reaching 19 145 kg/ha.In summary,under the conditions of this experiment,the combination of SS,NT and organic fertilizer application could significantly improve the physical properties of the soil,and the content of alkali-hydrolyzable nitrogen and available phosphorus also had a certain degree of improvement,and SS+OM treatment was beneficial to the increase of the yield of wheat-maize continuous cropping field in the Loess Plateau.
