为验证土壤中N2 O能否通过植物的输导组织由叶片释放从而干扰植物直接释放N2 O的定量测定 ,实验采用分室隔离法确证了土壤N2 O对测定某些作物 (如玉米、高粱 )直接释放N2 O的干扰 ;采用交叉培养法消除了这种干扰 ,准确地测定了大豆、玉米幼苗直接释放N2 O的强度 ;并研究了N、P营养与植物释放N2 O及体内NO 3 N浓度之间的相关性 .
In order to verify whether N2O2 in soil can be released from leaf by plant tissue and interfere with the direct determination of N2O released from plant, the compartmentalization method was used to confirm the direct effect of soil N2O on the determination of some crops (such as corn and sorghum) Releasing interference of N2 O; Eliminating this interference by cross-culture method, accurately measuring the intensity of direct release of N2 O from soybean and maize seedlings; Studying N, P nutrition and plant releasing N2 O and NO 3 N concentration in the body Relevance between.
