AbstractTo investigate the effcts of the plant growth regulator Iron Chlorine e6on rice growth，an experiment was conducted using the rice variety Ningxiangjing 9. The folowing treatments were applied： seed dressing with 0.02% Iron Chlorine e6 （A1， 22.5g/hm2 ；A2， 45.0g/hm2 ；A3， 67.5g/hm2 ；A4， 90.0g/hm2 ; CK， clear water control）; foliar spraying at the jointing stage （B1，22.5 g/hm²;B2，45.0 g/hm²；B3，67.5 g/hm²;B4， 90.0g/hm2 ; CK，clear water control）; foliar spraying at the booting stage （C1， 22.5g/hm2 ; C2， 45.0g/hm2 ; C3， 67.5 g/hm²; C4， 90.0g/hm2 ; CK， clear water control）. Thetraits，yield，andsafetyofriceplantsunderdifferenttreatments weredetermined.Theresultsshowedthatfoliar spraying of 0.02% Iron Chlorine e6 soluble powder increased panicle length and plant height，while seed dressing effctively thickened thebasal internodes and enhancedlodging resistance.Both methods，at applicationrates of 45.0- 90.0g/hm2 ，prevented lodging.Both seed dressing and foliar spraying of Iron Chlorine e6 increased the hundred-grain weight，seed setting rate，and yield of rice，with yield increases ranging from 2.14% to 11.95% . The C4 treatment achieved the highest yield （ 11303.55kg/hm2 ）. All treatments were safe for rice growth. Considering economic benefits， it is recommended to apply 0.02% Iron Chlorine e6 at 67.5g/hm2 during the booting stage to improve rice yield.
