【摘要】 1998~ 1999年在山西中部榆次旱作丘陵区试验、示范结果表明 :旱地玉米采用微孔地膜覆盖栽培具有明显的渗水、保水、增温效果。微孔膜覆盖生育期内土壤耕作层积温 ,较普通膜覆盖增高75℃· d;较裸地增高 2 5 2℃· d;微孔膜较普通膜覆盖具有一定的通透性 ,有调节土壤表层温度的作用 ;耕层土壤水分含量微孔膜覆盖较裸地增高 4 .3%~ 19.7%;微孔膜较普通膜增高 1.5 %~16 .7%,证实了微孔膜覆盖具有渗水效果 ;微孔膜覆盖较普通膜覆盖增产 4 .1%~ 5 .0 %,较裸地增产 4 6 .8%~ 96 .5 %。

【Abstract】 The experiments were conducted in Yuci city, central of Shanxi Province, where is a dry-land farming hilly area, during 1998~1999.The results show that Maize cultivation covering with perforated film in dry lands displayed apparently the effects of water penetration, water maintenance, and temperature increase. Compared the covering with the ordinary plastic film and nocovering the soil accumulated temperature increased by 75℃·d and 252℃·d; the soil water content increased by 4.3%~19.7% and 1.5%~16.7%; the yield of maize increased by 4.1%~5.0% and 46.8%~96.5% respectively.
