The loding has always been an important factor restricting the high and stable yield of maize in the black soil area of northeast China.In order to improve the anti-lodging ability of maize,takiing Xianyu 335 as the test material,chemical regulator was used at bell stage in maize,the effects of chemical regulator on antilodging characters of stalk and root were analyzed.The results showed that the plant height,ear position and length of lower internodes were reduced,while layers and total numbers of aerial root,density and breaking strength of internodes were improved.The use of chemical regulator could improve anti-lodging abilities of stalk and root significantly.
