Abstract：This study explored the efectsof plasticflm mulchingon theagronomic traitsof winterradish （Raphanus sativus L.） andthephysicochemical propertiesofsoilinHunan，aiming toprovidetechnicalsupportforeficientcultivationofadishinthe humid regionof southern China.The main winterradish variety'Baichuanxue'in Hunan was cultivated with film mulching （FM） andopenfieldcultivation（CK）.Teeffectsofthetwocultivationmodesonteagronomictraits，yield，andqualityofadishadthe physicochemical propertiesofsoil were evaluated.Theresultsshowed thatcompared with CK，FMimproved theagronomictraits， yield，andqualityindicatorsofadishandthesoilenvironment.ComparedwithCK，FMincreasedtherotweightperplantand yield by 38.5% and 36.8% ，while decreasing the skin cracking rate and pith rate by 7.39 and 14.83 percentage points，respectively. AditionallyFMprolongedthestorageperiodformorethan7days.ComparedwithCK，FMincreasedthewatercontentof020 cm soil layer and the proportion of water stable aggregates with particle sizes of 0.25-10mm by 8.62 and 8.00 percentage points， respectively， while decreasing the soil bulk density by 6.9% .In conclusion， plastic film mulching can improve the agronomic traits， yield，and qualityofradish and the soil environment.It is suggested that the patern of "plastic filmmulching + organic fertilizer + potassium fertilizer regulation" can be popularized in Hunan and similar ecological areas.
