以马铃薯品种荷兰15为试验材料,研究了小麦秸秆+普通膜、小麦秸秆+降解膜、玉米秸秆+普通膜、玉米秸秆+降解膜4种覆盖材料对耕作层土壤温度变化和产量的影响。结果表明,4个处理的马铃薯出苗率均在91%以上,生长期的温度变化曲线基本一致。小麦秸秆+普通膜的5 cm和10 cm地温低于其余3个处理。玉米秸秆+普通膜产量最高,达到55 300.0 kg/hm2;小麦秸秆+普通膜商品率最高,为87.67%。综合分析,小麦秸秆+普通膜是适合当地一草三膜覆盖马铃薯种植的较为理想的覆盖材料。

[Abstract]
The potato cultivar Holland 15 was used as the test material, adopt four ways which were wheat straw+common mulching film, wheat straw+degradation film, corn straw+common mulching film, corn straw+degradation film, to studied mulching material on soil temperature change and the effects of yield. The results showed that the emergence rate of the four treatments was above 91%, the temperature change curve of the whole growing period is basically the same. The ground temperature of wheat straw+common mulching film was lower than the other three treatments. The yield of corn straw+common mulching film was the highest, reaching 55 300.0 kg/hm2;the commodity rate of wheat straw+common mulching film was the highest, 87.67%.Based on the comprehensive analysis, wheat straw+common mulching film is an ideal mulching material for potato planting under one grass and three film mulching
