摘要
为了探讨半干旱区地膜覆盖对马铃薯土壤的增温和增产效果,以‘定薯1号’为试验材料,采用露地低垄、覆膜低垄、覆膜高垄杀秧、覆膜高垄有秧4种方式研究了覆膜对马铃薯耕层土壤的温度变化及产量的影响。结果表明;黑色地膜覆盖栽培具有增温作用,不同的覆膜起垄方式对土壤的增温效果不同,高垄有秧的土壤温度最高,达到14.01℃,高垄杀秧为13.49℃,低垄覆膜为12.63℃,对照低垄露地为11.80℃;覆膜高垄的产量显著高于低垄种植,其中覆膜高垄有秧产量达2 176 kg/667m2,增产效果显著。
Effects on soil temperature and tuber yield of cv. ＇Dingshu 1＇ were studied of four cultivation methods of low ridge with open field, low ridge with mulching, high ridge with mulching and plant killed, and high ridge with mulching and plant alive in order to understand the influence of mulching on soil temperature and tuber yield of potatoes in semi- arid area. Soil temperature was increased when black plastic film was used for coverage, with temperature increase varying with various treatments. Soil temperature was increased most for the treatment of high ridge with mulching and plant alive, up to 14.01 ℃,followed by high ridge with mulching and plant killed（13.49 ℃） and low ridge with mulching（12.63 ℃）. For low ridge with open field, the control, the temperature was only 11.80 ℃. Yield of high ridge with mulching was significantly higher than that of the low ridge, and yield for high ridge with mulching and plant alive was up to 2 176 kg/667m2, yield increase being significant.
