摘要 

以马铃薯与玉米间作体系中的马铃薯为研究对象,通过田间试验研究了间作马铃薯覆盖不同地膜对土壤温湿度及其产量的影响。结果表明:覆膜可明显提高土壤含水量和马铃薯生长前期的土壤温度,显著提高马铃薯的产量(P<0.01)。在与玉米间作条件下,白色地膜覆盖马铃薯对水分的保持效果最好,马铃薯增产效果最佳,其次是黑色地膜覆盖。在马铃薯出苗期至块茎形成期间覆膜处理的土壤温度均高于对照,在马铃薯块茎膨大期以后,白色地膜覆盖处理的土壤温度显著低于其他处理(P<0.05)。在马铃薯与玉米间作体系中马铃薯用白色地膜覆盖,其增产效果优于黑色地膜和降解地膜。

Abstract

The effects of different plastic film mulching of potato on soil temperature, moisture and its yield were studied by field experiment in potato and maize intercropping system. The results showed that the film mulching could increase the soil water content and the soil temperature in the pre-growth period of potato, and significantly increase the yield of potato (P<0.01). Under the condition of intercropping with maize, white film mulching had the best effect on water retention, and potato yield was the best, followed by black film mulching. The soil temperature during the period from the seedling stage to tuber formation was higher than that of the control. After potato tuber enlargement, the soil temperature of white plastic mulching was significantly lower than that of other treatments (P<0.05). In potato and maize intercropping system, the potato was mulched with white plastic film, and its yield was better than that of black plastic film and degradable plastic film.
