烟稻轮作中稻草还田对土壤有机氮各组分的影响
Effects of Rice-straw-returning Under Tobacco-rice Rotation on Soil Organic Nitrogen Fractions
摘要
Abstract
14 different soils under tobacco-rice rotation in southern Hunan Province were collccted to study the affects of rice-straw-returning on the contents and components of organic nitrogen fractions in soils based on Kecney and Brenmer's classification of organic nitrogen. The results showed rice-straw-returning only increased the content of unknown hyclrolysable nitrogen rather than the contents of ammonia nitrogen, amino acid nitrogen and unhydrolysable nitrogen; Rice-straw-returning enhanced the correlations between ammonia nitrogen, unknown hydrolysable nitrogen,unhydrolysable nitrogen and organic matter, total nitrogen, alkali-hydrolyzable nitrogen, while weakened thc correlations between amino acid nitrogen, amino sugar nitrogen and organic matter, total nitrogen, aikali-hydrolyzable nitrogen.关键词
