Abstract:
Taking dried pepper as the test material，the combined application of amino acid fertilizer and urea in the field was used.Under the same nitrogen application，seven fertilization treatments were set,no fertilizer (CK)，single urea (M0)，20% amino acid fertilizer+80% urea (M20)，40% amino acid fertilizer+60% urea (M40)，60% amino acid fertilizer+40% urea (M60)，80% amino acid fertilizer+20% urea (M80)，100% amino acid fertilizer (M100).The contents of organic nitrogen components in 0-20 cm and 20-40 cm soil layers at the harvest stage of pepper and soil protease，urease，nitrate reductase and nitrite reductase activity were determined.The effects of combined application of amino acid fertilizer and urea on soil organic nitrogen components and soil nitrogen-related enzyme activities were studied，and the correlation between organic nitrogen components and soil enzyme activities was analyzed，in order to provide reference for the application of amino acid fertilizer in pepper production.The results showed that combined application of amino acid fertilizer significantly increased the content of soil organic nitrogen components，with the order of ammonium nitrogen>amino acid nitrogen>hydrolysable unknown nitrogen>unhydrolyzable nitrogen>amino sugar nitrogen.When the amount of amino acid fertilizer application increased，the total nitrogen，amino acid nitrogen，ammonium nitrogen，unknown nitrogen，urease，protease，and nitrate reductase activities in the same soil layer would first increase and then decrease.Among the organic nitrogen components，except for amino sugar nitrogen and unhydrolyzable nitrogen，the highest values were observed in treatment M20；among the soil enzyme activities，except for the maximum protease activity in treatment M20，the other treatments reached maximum values at M60.The correlation analysis showed that the content hydrolyzed total nitrogen was significantly positively correlated with total nitrogen，and significantly negatively correlated with unhydrolyzable nitrogen.Amino sugar nitrogen，hydrolyzed unknown nitrogen，and total nitrogen were significantly positively correlated with the four enzyme activities.In conclusion，treatment M20 had the highest soil nitrogen supply potential and could effectively improve the nitrogen use efficiency of pepper plants.
