本文研究了耕垦对砖红壤和黑土的氮素形态分布和氨基酸组成的影响。结果表明,耕垦导致土壤中氨基酸态氮、N—苯氧基氨基酸态氮和非α—氨基酸态氮含量下降;土壤中非水解性氮仍有一定的有效性。
This paper studied the effects of cultivation on the distribution of nitrogen forms and amino acid composition in brick loess and black soil. The results showed that the contents of amino acid nitrogen, N-phenoxy amino acid nitrogen and non-α-amino acid nitrogen in soil decreased with the cultivation. The non-hydrolyzable nitrogen in soil still had some effectiveness.
