摘要
为了明确不同季节麻地膜覆盖栽培保温特性及对作物生长和产量的影响,分别在冬季、春季和夏季进行不同地膜覆盖白菜对比试验。结果表明:不同季节麻地膜覆盖均能提高土壤温度,增温效果平缓,夏季不会出现膜下高温情况。麻地膜覆盖能够促进白菜出叶速率、增加株高和叶片数、增大叶面积。不同季节和不同覆盖处理间互作效应极显著(P<0.01),春季和夏季麻地膜覆盖的增产效果比冬季明显。春季和夏季麻地膜覆盖下白菜产量分别比无覆盖高45.97%和48.89%,均呈显著差异(P<0.05);分别比塑料地膜覆盖的高6.66%和51.05%,也均达显著差异(P<0.05)。
In order to identify the heat preservation of bast fiber mulching film and its effects on growth and yield of crops in different seasons, the comparison tests of Chinese cabbage covered by different films had been conducted in winter, spring and summer respectively. The results showed that bast fiber mulching film could increase the soil temperature in different seasons and the effects were stable. In summer, the temperature under the bast fiber mulching film would not reach too high. With the covering of bast fiber mulching film, it could increase the rate of leaf emergence, the plant height, leaf number and leaf area. The interaction between different seasons and different covering was significant （P0.01）. And the yield-increasing effects in spring and summer were more remarkable than winter. The yield of Chinese cabbage covered with bast fiber mulching film in spring and summer were 45.97% （P0.05） and 48.89% （P0.05） respectively higher than that of Chinese cabbage without film; which were also 6.66% （P0.05） and 51.05% （P0.05） respectively higher than that of Chinese cabbage covered with plastic film.
