黑色地膜覆盖对土壤理化性质及萝卜产量与商品性的影响
Effect of Black Plastic Film Mulching on the Physicochemical Properties of Soil and the Yield and Commerciality of Radishes
摘要
Abstract
To investigate the effect of black plastic film mulching on the physicochemical properties of soil and the yield and commerciality of radishes in rice stubble fields,this study established two treatments:black plastic film mulching(T)and open-field cultivation(CK).The physicochemical properties of soil and the mineral element content,commerciality,and yield of radishes were compared and analyzed.The results showed that in the 0-20 cm soil layer,T increased the water content and proportion of 0.25-10 mm aggregates by 6 and 10 percentage points,respectively,while decreasing the bulk density by 8.9%,compared with CK.The effect weakened in the 20-40 cm soil layer.Compared with CK,T extremely significantly increased the hydrolyzable nitrogen(68.42 mg/kg)and available potassium(162.30 mg/kg)in the 0-20 cm soil layer by 53.3%and 49.7%,respectively,and significantly increased the tolal nitrogen(0.44 g/kg),tolal potassium(0.35 g/kg),and organic matter(0.92 g/kg)by 37.5%,66.7%and 37.3%,respectively,while decreasing the content of available phosphorus and total phosphorus and alleviating soil acidification.Regarding radishes,T extremely significantly increased the content of iron,nitrogen,and potassium by 31.7%,19.3%,and 18.0%,respectively,compared with CK.The equivalent yield of T reached 4 579.74 kg/667m2,representing a 17.09%increase compared with CK.Meanwhile,radishes of T showed significant decreases in pithiness rate,root cracking rate,and root branching rate and improvement in skin smoothness,demonstrating good commerciality.Overall,black plastic film mulching in radish cultivation could significantly improve the physicochemical properties of soil in the rice stubble field,with stronger effect at the surface layer and attenuated effect at the deep layer.Meanwhile,it significantly improved the yield,growth indicators,and commerciality of radishes.关键词
