摘要
青菜逆态试验应用正交设计与回归分析相结合的方法，在叶龄、受淹时间与指标之间，通过试验结果建立的数学模型，经回报检验结果，平均相对误差在2％左右，可用于市郊夏季暴雨对青菜受淹后的损失率预报。同时对俺水后青菜根系呼吸，以及土壤中氧化还原电位等机理进行了分析。
Adverse state tests of Brass ica campestrls L. ssp. chinensis at various leafages and under treatments with different inundation times were conducted by a method combining orthogonal design and regression analysis in Shanghai Sheshan Experimental Station of Farmland Water Conservancy in 1996. Then according to the test results, the mathematical predicting models were set up. The results of accuracy check showed that the mean relative error was about 2%; so these models can be used for predicting the loss rates of Brassica campestris L. ssp. chinensis inundated after summer rainstorm in Shanghai Suburbs. Moreover, some related mechanisms such as respiration of pakchoi and redox potential in soil after inundation are also analysed in this study.
