Effects of Plastic Film Mulching on Agronomic Traits of Winter Radish and Physicochemical Properties of Soil in Hunan Province
摘要
Abstract
This study explored the effects of plastic film mulching on the agronomic traits of winter radish(Raphanus sativus L.)and the physicochemical properties of soil in Hunan,aiming to provide technical support for efficient cultivation of radish in the humid region of southern China.The main winter radish variety'Baichuanxue'in Hunan was cultivated with film mulching(FM)and open field cultivation(CK).The effects of the two cultivation modes on the agronomic traits,yield,and quality of radish and the physicochemical properties of soil were evaluated.The results showed that compared with CK,FM improved the agronomic traits,yield,and quality indicators of radish and the soil environment.Compared with CK,FM increased the root weight per plant and 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.Additionally,FM prolonged the storage period for more than 7 days.Compared with CK,FM increased the water content of 0-20 cm soil layer and the proportion of water stable aggregates with particle sizes of 0.25-10 mm 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 quality of radish and the soil environment.It is suggested that the pattern of"plastic film mulching+organic fertilizer+potassium fertilizer regulation"can be popularized in Hunan and similar ecological areas.关键词
