Value Analysis of Ridge and Furrow Planting Pattern on Maize Growth and Yield in Southern Shaanxi

Furrow planting mode has a very high application value in process of corn planting, which can directly affect growth and yield of corn．Compared with traditional planting mode, it has significantly improved plant height, functional leaf area, relative chlorophyll content, dry matter weight and yield of corn, which promotes healthy growth of corn plants．Theoretical basis of furrow planting model was introduced, and working principle and relative advantages of the model were understood．Then combined with land conditions and climate conditions in Southern Shaanxi, the third level terrace of Weihe River Basin in Shaanxi Province was selected as test site to complete relevant experimental design．Finally, according to effect of ridge furrow planting mode on growth and yield of maize, value of ridge furrow planting mode in Southern Shaanxi was analyzed．
