摘要
以黑色膜、转光增温膜和配色膜为试材 ,研究了地膜覆盖对春季马铃薯生长和产量的影响。结果表明 ,转光增温膜的增温效果最好 ,其次是配色膜 ,黑色膜的效果较差 ,但也好于普通透明地膜 (CK)。转光增温膜和配色膜覆盖的马铃薯出苗较快 ,长势好 ,产量显著高于CK。黑色膜覆盖的马铃薯出苗稍晚 ,植株长势和产量受到一定影响 ,但其产量仍明显高于CK。配色膜与黑色膜覆盖在防除杂草和防止马铃薯块茎表皮变绿方面有明显效果。综合各项测定指标 ,认为配色膜的总体效果最好。
The effect of different plastic film mulch on growth and yield of potato were studied. The result indicated that black film, spectrum transformation film, and colorcomnination film mulch all had better effect on reducing soil temperature than the control, and which the spectrum transformation film was the best one, followed by the colorcomnination film. Therefore, potato seedlings with spectrum transformation film mulch and colorcomnination film mulch came up earlier, the plants grew better, and the yield were higher than those of the control significantly. The seedlings with black film mulch came up a bit latter, so the growth and yield got a certain influence, but the yield was still higher than that of control significantly. The colorcomnination film mulch and black film mulch had significant effect on prevent weeds and potato tubers green changes. It was suggested that the overall effect of colorcomnination film mulch was the best one.
