【摘要】 以欧洲类型短黄瓜为试验材料,研究了秋冬季节塑料大棚下畦面地膜覆盖、畦面覆膜畦沟铺稻壳、畦面畦沟全膜覆盖3种不同的地膜覆盖对大棚空气温湿度、土壤温度、CO₂浓度以及黄瓜产量的影响。结果表明:畦面覆膜畦沟铺稻壳的方式降低了土壤温度,使得大棚内空气湿度略有增加,容易诱发病害。畦面畦沟全膜覆盖明显地提高了大棚内的空气温度和土壤温度,降低了空气湿度,增加了CO₂浓度,这些都有利于秋季黄瓜的生长和减少病害的发生,从而提高了黄瓜产量。更多还原

【Abstract】 A vinyl-house culture of European short cucumber was conducted in autumn-winter season by plastic mulching only on ridge surface,plastic mulching on ridge surface and rice husk mulching on furrow,and plastic mulching on both ridge surface and furrow to investigate the air temperature and moisture,soil temperature,CO₂ concentration,and cucumber yield as influenced by the 3 different plastic mulching methods.The results showed that the plastic mulching on ridge surface and rice husk mulching on furrow decreased the soil temperature,made the air moisture somewhat increase and was prone to induce disease.The plastic mulching on both ridge surface and furrow obviously improved both air and soil temperatures,decreased the air moisture and increased the CO₂ concentration,which were beneficial to cucumber growth and decrease of disease incidence and could gain a higher cucumber yield.更多还原
