摘　　要：为了研究地膜覆盖对粉用马铃薯生长的影响,对宁夏西吉地区主栽的宁薯4号品种采用不同播期下地膜覆盖和未覆膜两种栽培措施进行对比试验。结果表明,覆膜能使马铃薯开花期提前,从而增加薯块的生长时间,5月上旬到7月中旬,保水效应和抗旱增产效果明显,覆膜比未覆膜增产47.8%～67.2%。对主栽的青薯168号采用不同时期覆膜和不同时期揭膜的栽培方式进行对比试验,结果表明在播种前覆膜可以优化土壤环境,在块茎增长时期以后揭膜可以提高马铃薯的覆膜效果,提高马铃薯产量,最高增产可达76.3%。因而,在马铃薯种植期间使用地膜覆盖并适时的覆膜揭膜,能有效提高粉用马铃薯的品质及商品性。In order to study effects of film mulching on the growth of potato,Ningshu-4 was sown on different sowing dates and comparative tests on the two situations,film mulching and no film mulching in Xiji,Ningxia,were conducted.The results showed that film mulching could speed up the growth period of tuber with an early blooming.From early May to mid July,its water saving and drought resistance function had obvious effects on its quality and production which increased by 47.8%-67.2% than under the no-film-mulching condition.＂Qingshu-168＂ was also chosen to conduct the comparative tests on film time and film-off time,and it turned out that the soil could be optimized when the film was coated before planting while removing it after tuber growth period,the maximum production could be increased to 76.3%.As a result,using film and determining the timing of the film mulching and removing could effectively improve the quality and marketability of potatoes.
