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。
The reversal test of vegetables with orthogonal design and regression analysis combined with the method, the leaf age, flooded time and the index between the mathematical model established by the test results, the return test results, the average relative error of about 2%, available Prediction of the loss rate of submerged green vegetables after summer heavy rains in the suburbs. At the same time, the root respiration of vegetables after I water, as well as the redox potential in the soil were analyzed.
