3. the fixing quantity of ammonium in soils tested increased with the increasing of the fixation time, and the fixation rate was the largest at the beginning several hours. the releasing amount of fixed nh / in soils tested increased with the incubation time, and the velocity of fixed - nh4 + - release was very slow
供試土壤對外源銨離子的累計固定量隨時間的延長而迅速增加,反應以開始階段固定速率最大,由同種母質發育的酸堿度不同的土壤對銨離子的固定能力不同。The content of fixed ammonium, capacity of fixing - ammonium, available fixed ammonium, kinetics of ammonium fixation and release of fixed ammonium of chief upland cultivated soils in hunan province were studied by using the method of field investigation and sampling, laboratory incubation and analyses. the seasonal change of fixed ammonium content in soil and _ its bioavailability in different growth stage of huanghuacai by use of field plot experiment
本文通過野外調查取樣、室內培養試驗和分析測定,研究了湖南省主要旱耕地土壤的固定態銨含量、固銨容量、有效性固定態銨含量以及土壤對銨離子的礦物固定和土壤固定態銨釋放的動力學特性,通過田間小區試驗,研究了不同施肥結構下土壤固定態銨在黃花菜生長期間的動態變化規律及其生物有效性。The enzyme retained full activity after being treated at room temperature for 1 hour at ph between 4. 0 and 11. 5. the enzyme can be incubated at 50 for 4h with only less 50 percent loss of activity and is stable in the frozen state. when streptomyces griseus atcc14811 was cultured in 10. 3 % sucrose yeme liquid medium, production of extracellular cholesterol oxidase increased for 5 days before decrease
利用硫酸銨鹽析及deae -纖維素離子交換柱層析提取純化灰色鏈黴菌atcc14811發酵上清液中的膽固醇氧化酶,理化性質研究表明酶作用晟適ph為8 . 0 ,最適溫度為45 , ph穩定范圍在ph4 . 0 - 11 . 5之間,在50條件下保溫4h ,仍保留54酶活力。The release of fixed ammonium still continued at the reaction time of 42 days. ph was an affecting factor of nh4 + - fixation in soil and the category of cation was an affecting factor of fixed - nh4 + - release from soil
供試土壤固定態銨的累計釋放量隨著時間的延長而緩慢增加,反應42天仍未達到最大值,土壤溶液中陽離子種類能影響固定態銨的釋放。分享友人
