Abstract:
Taking maize as test material,based on equal nutrient supply,five treatments were designed,including chemical fertilizer(T1),carbon-based fertilizer(T2),carbon-based fertilizer combined with chemical fertilizer(T3),slow-release fertilizer (T4),organic fertilizer combined with chemical fertilizer(T5),and no fertilizer as control.Through two years field positioning test,the effects of different fertilization measures on soil aggregate formation,soil chemical properties and enzyme activity were studied,in order to provide reference for improving soil structure and preventing agricultural non-point source pollution.The results showed that compared with chemical fertilizers,the combined application of carbon-based fertilizer and chemical fertilizer could significantly increase the content of water-stable macroaggregates (WSA>0.25 mm) in 0-20 cm and 20-40 cm soil layers by 75.7% and 64.4%,respectively.The contents of soil organic matter,available phosphorus and available potassium at 0-20 cm level were significantly increased;the number of soil fungi,bacteria and actinomycetes at 0-20 cm level were significantly increased;soil phosphatase activity was significantly increased by 18.6%,catalase activity was 5.3%,urease activity was 59.4%,and soil enzyme activity was significantly enhanced,which had the same effect as organic fertilizer and chemical fertilizer.In summary,combined application of carbon-based fertilizer and chemical fertilizer can significantly improve the physical and biological properties of calcareous soil and improve soil quality.
