Yingjie Guo · Jilin Nongye Daxue xuebao · 1999
A regression model about soil bulk density,moisture content and germinating seed rate was established with the method of quadratic orthogonal rotary regression.Meanwhile, the paper descriped water flow curve of light chernozem soil under different rolling condition by the method of dairy following measure.
