Effects of Commercial Organic Fertilizers on Physical and Chemical Properties of Sandy Fluvo-Aquic Soil,Yield and Nutrient Accumulation of Winter Wheat
In order to find out commercial organic fertilizers suitable for fertility improvement and crop yield increase in sandy fluvo-aquic soil,a winter wheat field trial was conducted in Xinxiang County,Henan Province from 2021 to 2022.The effects of different commercial organic fertilizers(carboniferous organic and inorganic compound fertilizer,bacteria-containing compound fertilizer,bacteria-containing organic fertilizer,carboniferous organic fertilizer,humic acid organic fertilizer)on physical and chemical properties of sandy fluvo-aquic soil,winter wheat yield and nutrient absorption and utilization were studied with single application of chemical fertilizer as a control.The results showed that the application of commercial organic fertilizer significantly increased the yield of winter wheat by 24.6%—49.7%,in which the application of carboniferous organic and inorganic compound fertilizer and carboniferous organic fertilizer increased the yield by 49.7%and 43.8%,respectively.The application of carboniferous organic and inorganic compound fertilizer significantly increased the above-ground nitrogen,phosphorus and potassium accumulation by 44.6%,43.1%and 54.4%,respectively.The application of carboniferous organic fertilizer significantly increased by 24.8%,33.5%and 45.5%.The application of commercial organic fertilizer could reduce the bulk density of 0-10 cm soil,and the contents of organic carbon and available potassium in sandy fluvo-aquic soil with carbon organic and inorganic compound fertilizer,bacterial compound fertilizer,carboniferous organic fertilizer and humic acid organic fertilizer were significantly increased by 33.1%—44.8%and 10.8%—16.7%,respectively.In addition,the application of carbonaceous organic and inorganic compound fertilizer and carbonaceous organic fertilizer could also increase the proportion of soil aggregates>0.25 mm,and significantly improve the activities of α-glucosidase,β-cellobiosidase,β-xylosidase,leucine-aminopeptidase and phosphatase in soil.The above results show that carboniferous organic and inorganic compound fertilizer and carboniferous organic fertilizer by reducing the bulk density of 0-10 cm soil,promoting the formation of soil large aggregates,and increasing the content of organic carbon,available potassium and soil extracellular enzyme activity,achieve the increase of winter wheat yield and nutrient accumulation.They are suitable commercial organic fertilizers for sandy fluvo-aquic soil.
