rice varieties were hydroponically cultured in 2001 and 2002 respectively, The tested rice varieties were classified into 6 types based on their yield level by the MinSSw method to investigate the differences of nitrogen uptake and use efficiency among different grain yield types of rice varieties.
结果表明:抽穗期植株含氮率高,抽穗前、后的氮素吸收量大,抽穗后吸收的氮素比例大,成熟期运转到穗部的氮素比例高,氮素籽粒生产效率及氮素收获指数高是高产品种氮素吸收利用的基本特征。

The potential of post-anthesis nitrogen uptake in wheat may become a limiting factor with the increasing grain yield providing that the grain protein content stablises.
鲁麦14号虽然单株产量较高,但开花期叶叶片氮浓度低,开花后氮吸收少且叶片氮素输出快,可能成为其产量潜力增加的的重要限制因素。

肾小管葡萄糖最大重吸收量试验
一种测定肾小管重吸收功能的试验。利用单位时间内肾小球滤出的葡萄糖量减去单位时间尿中出现的葡萄糖量,可计算出TMG值。测定方法:晨7时30分首次静脉注射40%葡萄糖溶液150ml,以后用30%葡萄糖溶液每分钟10ml速度维持输液。其他操作同*菊糖清除率,同时测定菊糖清除率以求出肾小球滤过率,然后按下式计算TMG值。TMG=PG×Cin-UG×V,式中PG为血浆葡萄糖浓度,Cin为菊糖清除率,UG为尿中葡萄糖浓度,V为每分钟尿量。正常人TMG平均值为340± 18.2mg/min/1.73m2。男性为300~450mg/min/1.73m2,女性约250~350mg/min/1.73m2。TMG的高低可反映有效肾单位的数量和功能,是测定近曲肾小管重吸收功能的指标之一。
