摘要
对10月份间作荞头与紫薯林地的空气温度、空气相对湿度、光照强度与露点变化进行观测,研究油茶幼林秋季间作对小气候因子的影响。结果表明:调节林间空气温度能力大小的作物排序为荞头>紫薯>清耕(对照);调节林间空气湿度能力大小的作物排序为荞头>紫薯>清耕(对照);调节林间光照强度能力大小的作物排序为紫薯>荞头>清耕(对照);调节林间露点能力大小的作物排序为荞头>紫薯>清耕(对照)。因此,紫薯和荞头对秋季油茶幼林小气候具有明显的改善作用,研究结果可为油茶间种改善林地秋季小气候提供参考依据。
The changes of air temperature,relative humidity,light intensity and dew point of meteorological factor on Solanum tuberdsm and Allium Chinese interplanting were observated in October.The effects of autumn intercropping of Camellia oleifera on microclimate was studied.The results showed that crops with the ability to regulate the air temperature in the forest were ranked as Allium Chinese>Solanum tuberdsm>tillage(control).Crops with the ability to regulate the air humidity in the forest were ranked as Allium Chinese>Solanum tuberdsm>tillage(control).Crops with the ability of adjusting light intensity in the forest were ranked as Solanum tuberdsm>Allium Chinese>tillage(control).Crops with the ability to regulate dew point in the forest were ranked as Allium Chinese>Solanum tuberdsm>tillage(control).Therefore,Solanum tuberdsm and Allium Chinese can significantly improve autumn microclimate of Camellia oleifera young plantation.The results can provide a reference for the improvement of autumn microclimate of Camellia oleifera intercropping.
