In order to explore the effect of no-tillage semi-solid direct seeding mode on the morphological structure and physiological activity of rice root system,through the field comparison experiment of designing tillage semi-solid (FZ),no-tillage semi-solid (MZ),rice transplanting (YZ) and traditional seeding (CK),the changes of rice root growth characteristics under different cultivation patterns were studied. The results showed that the root morphology,root oxidation activity,root bleeding sap intensity and its components were different in 2 years. The dry matter,root number,root volume,longest r...
