解釋
高有機土-
Soil ph value ranged from 6. 0 to 7. 2, the ph value had no markedly difference among the three horizons in each plot, and so did that among seven types of forest. the organic matter content in horizon a of plot g2 ( coniferous forest ) was the highest ( 193. 03a kg - 1 ) in seven plots and the lowest one was in plot g3
另外,在3個固定樣地內( g _ 1 、 g _ 2 、 g _ 3 ) ,通過埋袋試驗,研究了白樺枝條、白樺凋落葉、岷江冷杉凋落葉等3類典型凋落物在3個不同埋藏深度土壤中的分解。 -
The n ( subscript org ) contents of samples dried at 105 was highest among the samples of field - fresh, being fumigated with chcl3, drying at temperature of room, 40 and 105 which came from not only a part of the microbial biomass nitrogen, but also from the decays of large organic molecules of soil nitrogen constituents
進一步分析結果看出, 105處理后的土壤易礦化有機態氮除了部分來自土壤微生物態氮的降解產物之外,還有一部分是靠高溫將土壤本身大分子含氮化合物分解而產生的。 -
Crop rotation plus fertilizer application produces the highest crop yields and maintains the highest soil n and organic matter levels
作物輪作加施肥產生最高作物產量,並保持最高土壤氮和有機質水平。
