1.
The relationship between relative yield and relative water use is formulated.
揭示了喷灌条件下冬小麦生长指标的变化规律 ,建立相对产量和相对耗水量的模型 ,分析水分亏缺敏感指数 ,并提出了喷灌条件下适宜灌水定
2) relative yield total (RYT)
相对产量之和
3) relative yield
相对产量

Through pilot experiment,it is found that the cotton yield is obviously influenced by multi-stage water logging;the degree of water logging can be described by the water logging factors such as SFW,SEW_50,and SFEW_50;there is a significant linear relationship between the cotton relative yield Ry and the water logging factors such as SFW,SEW_50,and SFEW_50.
通过测坑试验发现棉花受多过程涝渍胁迫后减产严重,涝渍程度可用涝渍因子(SFW、SEW50、SFEW50)来描述,棉花相对产量(Ry)与涝渍因子(SFW、SEW50、SFEW50)之间存在着显著的线性关系。

Soil alkali-hydrolyzable N were classified as very low(<50%relative yield ),low(50%～75%relative yield ), medium(75%～90%relative yield ),high(90%～95%relative yield ) and very high(>95%relative yield ) based on the relative yields.
以相对产量为50%、75%、90%和95%为标准将土壤碱解氮划分为极缺、缺、中等、高和极高5级。
3.
relative yield and salt mass per unit area vs.
在搜集、统计大量咸水灌溉试验资料的基础上,选取咸水充分灌溉条件下矿化度和小麦产量的完整对应数据103组,统计分析了灌溉水矿化度及单位面积盐分带入量对小麦相对产量的影响,结果表明,随着灌溉水矿化度的增加,小麦相对产量呈线性递减趋势,当矿化度大于1。
5) Invariant and covariant
绝对量和相对量
6) Relative Yield Total
相对总产量
