摘要
研究了间种鸭茅Dactylis glomeratacv.Amba和白三叶Trifolium repenscv.Haifa对苹果园区小环境的影响。结果表明:与传统清耕区相比,间种鸭茅和白三叶均能有效改善园区地温和气温,提高园区空气相对湿度。特别是盛夏高温时,能有效降低园区地温和气温;秋冬寒冷天气时,有保持土壤温度作用。还增加了园区草被地表覆盖,增强了土壤保水能力,改善了土壤理化性状,为果树生长提供了更加适宜的园区小环境。
The effects of inter-planting Dactylis glomerata and Trifolium repens as cover crops on the microclimate of apple orchard were studied. The results showed that the inter-planting orchard grasses, compared with clean tillage, could improve the ground temperature, air temperature and air relative humidity in the apple orchard, especially, could decrease the ground and air temperature on the hot summer, keep the ground temperature in the cold winter and end-autumn. And because the soil surface was covered with the grasses, the soil water-holding capacity and the soil organic matter could be increased, and the soil physical and chemical properties were improved as well. Therefore, a better suitable environment could be provided for the apple trees.
