Effect of acid rain on leaching loss of nitrogen and phosphorus
酸雨對紫色土氮磷淋失的影響 -
Severe fires can often cause changes in successional rates and soil hydrologic functions, degradation of soil physical properties, alter c : n ratios, and result in subsequent nutrient loss through accelerated erosion, leaching or denitrification, and alterations in microbial populations and associated process can occur
高強度火燒往往能引起演替頻率的改變,土壤物理性質退化,水文功能發生改變,改變c n比,加劇侵蝕、淋溶和反硝化作用,導致養分流火,微生物數量及其相關過程發生變化。 -
Factors such as soil texture, landscape, climate, irrigation, crop type, and nitrogen management influence intensity of no3 - loss through leaching
土壤質地、地貌、氣候、灌溉、作物類型和氮素管理等因素影響到淋失的強度。 -
Nitrate leaching, although slightly higher under no tillage, is generally not a major pathway of loss in summer crops
實施免耕的初期,氮的生物固定明顯,但隨著時間的推延,這種作用逐漸消失,以至到了後期,與初期的情況正好相反。 -
Therefore, it is useful to decrease nitrogen application amount or even with n application in split time so as to decrease the n loss and leaching in the paddy - field. 6. to define and calculate even productivity of nitrogen in the surface water - body ' of paddy field ( epnw ), marginal productivity of nitrogen in the surface water ( mpnw ) and elasticity coefficient of nitrogen in the surface water ( ecnw ), indicated that epnw and ecnw increased with n application amount increase, however mpnw has no the rule
6 .定義和計算水氮平均產生力、水氮邊際產生力和水氮產生力彈性系數,表明水氮平均產生力和水氮產生力彈性系數是隨著施氮量的增加而增加的,而水氮邊際產生力隨施氮量的增加並沒有表現出明顯的增加趨勢。 -
As the increase of water added, the level of no3 - n in soils was decreased, in comparison with fif, it is concluded that dif significantly decreased the leaching loss of urea - n from soil, and increased the available nitrogen in soil
總之,與澆灌施肥相比,滴灌施肥顯著地減少了尿素態氮的淋溶損失,增加了土壤中有效態氮的含量。
