作物敏感指数与敏感系数的分析与研究

Analysis and Study on Crop Sensitivity Index and Sensitivity Coefficient

本文就作物的相对产量和各生育阶段的相对腾发量,以詹森的相乘模型和布兰克的相加模型为基础,采用多元回归的方法,对我省城、望都、临西三个灌溉试验站5～7年的田间试验数据进行了分析计算,给出了两模型中的敏感指数和敏感系数,并用此两模型估算出了水分亏缺情况下的作物产量、并与实测产量进行了比较。

In this paper, the crop sensitivity index and sensitivity coefficient have been analysed and estimated, of the Jensen's multiplication model and Blank's addition model, acceding to the data of the plot test of winter wheat at the irrigation ex-perimenr stations of Gaocheng, Linxi and Wangdu of Hebei province for 5-7 years, regarding the relative yield and the relative evapotranspiration of every interval by using variables regression, and the crcp yield have teen evaluated in case of water deficit by use of the models, and compared with experiment yield.
