安徽阜阳地区甘薯地膜覆盖栽培技术研究

Study on Cultivation Technology of Sweet Potato with Film Mulching in Fuyang Area of Anhui Province

[目的]探讨甘薯地膜覆盖栽培的增产效应。[方法]通过不同覆膜方式及覆盖不同类型地膜的对比试验,研究覆膜条件下甘薯生长发育动态及对产量和品质的影响。[结果]阜阳地区春薯覆膜种植,在生长前期可以提高根部地温,改善土壤结构,促进前期的生长发育,使结薯期提前,从而提高甘薯产量,增加种植收益。[结论]研究结果为甘薯高产栽培提供了理论依据。

[Objective] The aim was to explore the yield effect of mulching cultivation for sweet potato.[Method] The dynamic growth of sweet potato and effect of film conditions on sweet potato were studied ,by comparison tests with diffel^nt coating methods and different types of mulch. [Resultl The results showed that fihn muh＇hing of spring planting potato in Fuyang area could improve the geothermal around the roots, improve soil structure, promote the growth of early, so early tuber period, thereby increased potato production, and increased revenue planting. [Conclusion] The results provided a theoretical basis for the high-yield cultivation of sweet potato.
