Abstract：Toinvestigate theeffects oforganicacidsand small moleculesiliconon thecadmiumreductionabilityand yieldofrice，relevantfieldexperiments wereconducted.Research hasshown that therearesignificantdiferences inthe sensitivityofdifferentricevarietiestodiferentfoliarinhibitors，andrelevantadaptabilityassessmentsshouldbeconducted beforepromotion;diferent foliar inhibitors may have different mechanisms forinhibiting cadmium enrichment in rice. Among them，organicacids mainlyacton thecadmium transferchannels intheaboveground partof rice，but have no significant effectonthecadmiumabsorptioncapacityof ricerots.Themain targetofsmall molecule siliconforcadmium reduction is to inhibit the transfer of cadmium from soil to roots.
