氮素同化作用 的英文怎麼說
中文拼音 [dànsùtónghuàzuòyòng]
氮素同化作用
英文
nitrogen assimilation-
The dynamic change of nh4 +, no3 - and tn, under the situation which urea was applied in the high fertility paddy - field in yuhang of hangzhou city with a lysimeter which was designed and made by ourselves, was studied and analyzed in order to find the rules of the change in the water - body of surface and the leakage rule of nitrogen, to reduce the effect of nitrogen loss on the water pollution
藉助自行設計製作的稻田滲漏計，在杭州餘杭對高肥力稻田不同施用尿素氮肥情況下，稻田地表水和滲漏水中銨態氮、硝態氮和總氮（簡稱三氮）的動態變化規律進行了研究分析，以利於發現氮素在地表水體變化和淋失規律，盡量減少氮素淋失對地下水體所造成的影響。This paper aimed at present status that most researches assembled in chemical products, adopted different determine methods, represented the transformation characteristic of nitrogen among water and soil of the sulphureous urea, confirmed the nutrient release speed, found out the optimum determine method in agricultural production application
針對目前對緩釋肥料釋放特性的研究集中在化工製作領域這一現狀，採用不同的測定方法，闡明含硫尿素中的養分氮在水及土壤中的轉化特點，確定養分的釋放速率，以求找出適合農業生產應用的方法。In light of current using situation and drawing on the experience of many scholars researched methods and viewpoints, this thesis made com land, fallow land, orchard, grass land as experimental field in black soil region jlau, which carried out experiment by applying different amounts of n and p fertilization in corn field. by means of collecting the samples of rainfall runoff, erosion silt and surface layer soil before and after rainfall for one year nature precipitation in field, we study the effect of surface runoff on n and p nutrient and fertility degeneration. the results showed : ( l ) there are lots of factors which affect soil erosion and losses of n and p, in which rainfall and rainfall intensity were more important, while rainfall intensity is the most important meteorological phenomena factor
針對當前黑土利用現狀，本文借鑒眾多學者的研究方法和觀點，在吉林農大黑土區選擇利用方式不同的玉米地、休閑地、果園、草地，在玉米區進行了不同數量的施肥，通過野外試驗，採集一年自然降雨產流及泥沙樣品，同時採集降雨前後的耕層土壤樣品，研究了黑土區地表徑流對氮磷養分特徵及肥力退化的影響，結果表明：土壤侵蝕和氮磷的流失受諸多因素的影響，降雨量、降雨強度是重要因子，而降雨強度是影響農田地表徑流養分流失的最重要的氣象因子，特別是暴雨，暴雨徑流中氮磷濃度較平時高得多；隨作物生長，覆蓋度逐漸增加以及不同利用方式下表現的覆蓋度差異，氮磷流失都表現為顯著的差異。N sources ( including organic and inorganic n tested ) and c sources tested could restrain methane oxidation. cellulose inhibited methane oxidation most weakly while the high concentration of methanol and glucose did dramatically, but the proper concentration of methanol could stimulate soil methane oxidation sharply. in the middle process of methane oxidation, addition of glucose could restrain methane oxidation shortly but the inhibition could be relieved about 5 days later when supplied again with enough oxygen
土壤微生物是甲烷氧化的主要生物類群，含水量對土壤甲烷氧化活性有明顯影響，過高或過低對甲烷氧化均具有抑制作用；氮源（包括有機和無機氮源）對甲烷氧化均有抑制作用；不同碳源對甲烷氧化的影響各異，纖維素對甲烷氧化抑制作用最小，而高濃度的甲醇、葡萄糖則對甲烷氧化具有強烈抑制作用；而適當濃度的甲醇可極大促進土壤對甲烷的氧化：在甲烷氧化過程中加入葡萄糖能迅速抑制甲烷氧化；在加入葡萄糖的同時保持瓶中充足的氧氣，則這種抑制作用可以在重新培養一定時間后得到解除。With adsorption and ion exchangeability, it is mainly used as additive in feed, it can absorb ammonia, fix nitrogen, delay the time nutriments stay in alimentary canal, absorb detrimental substance, improve the function of digest, supply many microelements and macroelemnts for livestocks
主要用作飼料的添加劑，具有吸附性和離子交換性，能吸氨固氮延緩營養物質通過消化道的時間吸附腸道有害物質，改善消化機能同時可以供給畜禽多種微量和常量元素，促進增產增重，提高飼料報酬。分享友人
