相对产量 meaning in Chinese
fractional yield
Examples
- The concept of relative yield was used to classify the rank of soil nutrition levels
利用相对产量概念来划分土壤养分水平等级。 - The best irrigation system can instructs the best distributed water quantity and the irrigated time under the condition of lacking water . thus , we can obtain the maximum relative yield and the least loss
优化的灌溉制度可用于指导在不同的缺水程度下如何在时间上定量分配水量，以使相对产量最大，减产损失最小。 - At the same time , using the results of model , the paper provides the optimization irrigation quota and the aim of high yield and high benefit based on the principle that the net benefit of unit water is highestusing the model , we can reasonably distribute the irrigation water for spring - wheat during growing period on the condition of different irrigation quota . through evaluating the comparative yield by the model , the paper gains that the reduction of spring - wheat output is biggest when the irrigation quote is between 100 and 200 . the thesis also gains that the corresponding economic irrigation quota is 170 - 120m3 / 667m2 . above results can provide scientific reference for irrigation water optimization distribution for crops in the individual irrigation area and the programming of irrigation district
在现有的生产条件下，可以利用模型在不同的灌溉定额下对春小麦生育期灌水进行合理的分配，并可以利用模型进行作物相对产量的评估，得出当灌溉定额在100 m 200范围内时，春小麦的产量下降幅度较大，最后得出相应的经济灌溉定额为170 120m ~ 3 667m ~ 2 ，为今后河套灌区各灌域多作物灌溉水量最优分配以及灌区的规划设计方面提供了科学参考依据。 - It can reflect soil water stress and salt stress . ( 6 ) choosing soil solution relative concentration as suitable variable established a funct - ion about crop relative yield , soil water and salt . using the way of testing model with actual data to valid its higher precision , it can reflect the relationship of crop yield , soil water and salt , and be considered as reference in water saving irrigation management
（ 6 ）选取试验条件下的适宜自变量-土壤溶液相对浓度建立作物相对产量与土壤水分盐分水盐响应模型，通过实测资料检验确认模型具有较高的精度，可以较准确地揭示作物产量与土壤水分盐分的量化关系，为含盐土壤的节水灌溉研究提供了一定的基础研究，可供灌溉规划管理参考。
