Nitrogen supplying capacity of three types of paddy soils in Tai-lake region were studied. Results obtained showed that (1) the mean value of the increments of clay mineral-fixed ammonium after anaerobic incubation of 9 air-dried soil samples was 17 ppm, which was equivalent to 28% of the increment of the exchangeable ammonium. It seems that the sum of the increments of exchangeable and clay mineral-fixed ammonium should be taken as the nitrogen mineralization capacity of the soils capable of fixing ammonium;...

Nitrogen supplying capacity of three types of paddy soils in Tai-lake region were studied. Results obtained showed that (1) the mean value of the increments of clay mineral-fixed ammonium after anaerobic incubation of 9 air-dried soil samples was 17 ppm, which was equivalent to 28% of the increment of the exchangeable ammonium. It seems that the sum of the increments of exchangeable and clay mineral-fixed ammonium should be taken as the nitrogen mineralization capacity of the soils capable of fixing ammonium; (2) results obtained in the field microplot experiments revealed that the contributions of subsoil to the nitrogen supplying capacity of the paddy fields ranged from 16% to 49%, with a mean value of 30%; and (3) difficulties in the prediction of nitrogen supplying capacity of a paddy field with incubation technique are discussed.

Anaerobic incubation of 560μmol/L trinitrotoluene(TNT),an explosive applied widely in the munitions and mining industries,with 1 mmol/L NADPH and 2 mg rat liver mitochondria protein/ml produced an electron spin resonance(ESR)spectrum of nitro anion free radical.The radical formation depended on all three components in the incubation system.In the presence of oxygen,the similar incubation manifested no observable ESR signal.Aerobically,TNT-stimulated oxygen consumption,superoxide(O2-)formation,NADPH oxidation and inhibited45Ca uptake by mitochondria were shown in dose-dependent manner.Addition of TNT into the 45Ca preloading mitochondria resulted in the increased 45Ca release from them,suggesting the disrupted Ca2+ compartment function of mitochondria.It was also shown that SOD and/or CAT reduced TNT-stimulated oxygen consumption and NADPH oxidation by mitochondria.

在无氧条件下,以560μmol/L TNT与1mmol/L NADPH和大鼠肝线粒体(2 mg蛋白/ml)在室温下温育,用ESR波谱直接观察到TNT还原活化后形成的硝基阴离子自由基信号,信号的出现取决于温育体系中的所有三种成分。若温育体系中通入氧气,则信号消失。在有氧条件下,不同浓度TNT(35~560μmol/L)与NADPH及鼠肝线粒体在37℃温育,可致线粒体氧耗明显增加,伴有超氧阴离子自由基的形成和NADPH的氧化,线粒体对~(45)Ca的摄取能力也有明显的下降,这些改变均呈明显的浓度效应关系。当560μmol/L TNT加入到~(45)Ca预负荷的线粒体中,线粒体中的~(45)Ca释放明显增加,提示线粒体对Ca~(2+)的隔离功能受损。研究中还发现,在温育体系中加入超氧化物歧化酶和/或过氧化氢酶,可减少TNT引起的线粒体氧耗增加及NADPH氧化。

Soil nitrogen mineralization under two conditions was studied with the methed of sealed anaerobic incubation and sampling at given locality. The amount of N mineralization of five soil samples under seaerobic incubation con-formed exactly to the power function fermula of effective temperature summation, yet N value couldn′t reflect the charactetistics of the soil N mineralization.The correlation between the amounts of N mineralization and N supplied by soil was not obvious and the amount of N mineralization couldn′t meet with the predi-ction of N supplide by soil. The amount and the ratio of N supplied by soil am-ounted to about 72.5kg/ha and 2.5%, respectively. At the same time, there was a most significant linear correlation between days after transplanting or at-mospheric temperature summation (above 15℃)and the amount of N supplied by soil, which provided a possibility to predict the amount of N supplied by Soil
