Nitrogen-fixation Potential of Nodules in Four Types of Nitrogen-fixation Plants and Their Influencing Factors in Dry-hot Valley

  • Received Date: 2012-02-16
  • In addition to water, Nitrogen (N) is often the key limiting factor for biological activity in Dry-hot Valleys. Biological N-fixation by nitrogen-fixation plants is of important source of N for vegetations in those areas. The nitrogenase activities (NAs) of nodules in Acacia auriliformis A. Cunn, Leucaena leucacephala (Lam.) de Wit, Cajanus cajan (L). Millspangh and Albiza kalkora Prain plantations were determined at the Dry red soils and Vertisol spots at four different sampling times in a Dry-hot Valley with the acetylene reduction assay. The results showed that the NAs of nodules in L. leucacephala (16.25 μmol·g-1·h-1) and A. auriliformis (15.85 μmol·g-1·h-1) were significantly higher than those in A. kalkora (9.60 μmol·g-1·h-1) and C. cajan (9.42 μmol·g-1·h-1). The NAs of nodules in rainy season were significantly higher than those in dry season, and approximated 2.3 times that in dry season. The NAs of nodules at the Dry red soils spots were 1.3-1.6 times higher than those at the Vertisol spots. The research revealed besides plant type, the NAs of nodules were primarily affected by soil type, season and soil water content, but less affected by soil temperature.
