林地气候环境条件影响油茶丰产的重要因素,为了促进油茶产业的高效、 低耗和常态化发展,以江西吉安县澧田乡马山林场3年生油茶林为试验对象,在油茶林地进行红薯、 大豆与花生3种常见农作物的间作试验,调查分析了间作后林间空气温度、 相对空气湿度、 光照强度、 表层土壤温度与浅层土壤温度5个指标,并应用灰色关联分析法筛选适宜油茶林地种植的间作物.结果表明:间作降低林间空气温度的大小依次为大豆>红薯>花生>清耕(对照);升高林间日均相对湿度大小依次为红薯>大豆>花生>清耕(对照);减弱林间日平均光照强度大小依次为花生>大豆>红薯>清耕(对照).对不同间作处理进行综合分析并排序为:大豆>红薯>花生>清耕(对照).因此,大豆和红薯对油茶林气象生态环境的改善作用显著,推荐在油茶幼林生长期推广应用.
Diurnal Effect on Meteorological Ecology of Intercropping Camellia oleifera Young Forest in Summer
Forest Climatic conditions are important factors affecting the high yield of Camellia oleifera. In order to promote the development of C. oleifera production more highly efficiency and normalized and lower energy con-sumption, 3 years old C. oleifera forest of Mashan Tree Farm which in Li tian village of Jiangxi Province was taken as the test object. Air temperature, relative air humidity, light intensity, topsoil temperature, shallow soil tempera-ture were suveried in C. oleifera forest which was intercropped with sweet potato, soybean, peanut, studying . Inter-crops that fit C. oleifera forest most were filtrated by grey correlation analysis method. The results showed that the in-ter-planting could reduce the forest air temperature as: soybean>sweet potato>peanut >control, increase forest daily average relative humidity as:sweet potato>beans>peanut>control, weak the average light intensity weak-ened proportional as peanuts>soybean>sweet potato>control. Comprehensive analysis was conducted among dif-ferent treatments, which were:soybean>Sweet Potato>peanut>control. Therefore, C. oleifera forest which inter-cropped with sweet potato, soybean improved meteorological environment and ecological environment significantly. It is worth popularizing application during the growth period.
