Abstract:The effects of four types of mulching models (surface tillage with straw mulching, no-tillage with straw mulching on furrow, no-tillage with stubble mulching, and no-tillage with straw mulching on ridge and furrow) on the root spatial distribution and the relationship between the roots and shoots of maize were investigated using stratified digging methods, with maize as the test crop. The distribution of maize roots was cone shaped and gradually extended from 20 cm to 40 cm below the surface during the elongat… Show more
