项目摘要
This project was made on physio-ecological research for various crcppmg systems in Thailand ainimg to determine the characteristic of each system under different meteorological condition and crop production methods on the basis of their systems and related microclimate. The following regions and orchards under either mono cropping or intercropping system incorporated with fruit trees, mango, longan, rambutan, lime, durian, and so forth, were surveyed : Chiang Mai, Khon Kaen, Bang Yai, Kampheng Saen, Rayong and Hat Yai. The microclimate of each orchard was successively measured by temperature and humidity data logger employed on canopy or bare field, and the photosynthesis activity was also estimated based on individual leaf at rainy- and dry-season. As results, the average and maximum temperatures in orchard irrespective of mono- or intercropping were lower than a bare field, while minimum temperature did not differ from each. High humidity was maintained in case of orchards ; the average and maximum relative humidities were left higher than a bare field As mentioned above, an interior microclimate, depends upon the type of cropping system and its combination.The light intensity at a saturation point of individual leaf was 800-1000 μmol m-2s-l during dry season, and 800-1400 μmol m-2s-l during rany season. No difference in photosynthesis activity among leaves at different quadrant and position was found regardless of dry- or rainy season. Their CERs at a light saturation pcdnt were, at range of 3.5 to l0.l μmol m-2s-l during dry season, and 5.5 to 17.81 μmol m-2s-l during rainy season ; all firot trees used in this survey showed the tendency above with one exception of rambutan. There was high positive correlation between CER and stomatal conductance irrespedive of kind offruit trees, and it is likdy that air moisture can sway the CER of tropical fruit trees as an important factor affecting the stomatal aperture during any season.
本项目对泰国不同作物生产系统进行了生理生态研究,以系统和相关小气候为基础,确定不同气象条件和作物生产方式下各系统的特性。调查了以下地区和果园的单作或间作系统与果树,芒果,龙眼,红毛丹,石灰,榴莲,等等:清迈,孔敬,邦艾,Kampheng Saen,罗勇和合艾。采用冠层温湿度记录仪和裸地温湿度记录仪连续测定了各果园的小气候,并根据单株叶片在雨季和旱季的光合活性进行了估算。结果表明,无论单作还是间作,果园的平均温度和最高温度均低于裸地,而最低温度差异不大。果园保持较高的湿度,平均和最大相对湿度都高于裸地。室内小气候取决于种植制度及其组合,旱季叶片饱和点的光强为800-1000 μmol·m ~(-2)·s ~(-1),旱季为800- 1400 μ mol·m ~(-2)·s ~(-1)。不同象限、不同叶位叶片的光合活性无论在旱季还是雨季均无差异。它们在光饱和pcdnt下的CER在旱季为3.5 ~ 10.1 μmol m ~(-2)s ~(-1),雨季为5.5 ~ 17.81 μmol m ~(-2)s ~(-1),除红毛丹外,其它所有的果树都表现出上述趋势。不同果树的CER与气孔导度之间存在着极显著的正相关关系,说明在任何季节,空气湿度都可能是影响热带果树CER的重要因素。
