Abstract：In order to explore the change in the growth of rice roots by mulch drip irrigation, japonica type rice “T-04”and “T-43” were adopted to study the form of rice root,roots, activity and nitrate reductase activity in mulch drip irrigation. The results indicate that at the depth of 20 cm,the length, surface area, volume and diameter of roots in mulch drip irrigation are all higher than those in the tradition basin irrigation. There is no significant difference at the depth of 40 cm;the activity of root on rice shows the trend of raising first and depressing later,and the highest stage and the tillering stage of rice are different in different cultivars of rice.The roots′ activity in mulch drip irrigation is higher than that in the tradition basin irrigation in the jointing-booting stage,full heading stage and milk-ripe stage. The anti-aging ability of roots is higher than that in mulch drip irrigation.Nitrate reductase(NR)activity in mulch drip irrigation is higher than that in the tradition basin irrigation. There is no significant difference in the tillering stage and milk-ripe stage. There is significant difference in the jointing-booting stage and full heading stage.
