水稻高产气象生态分析

影响水稻产量高低的气象因子包括光照、温度、降水、风速等。云南省永胜县涛源乡所具有的充足的光照时间、较强的光照度、含短波光比例较高的光质、较低的日平均气温和较大的昼夜温差、较少的降水量和降水日数以及适宜的风速,使当地水稻生长期延长,光合效率提高,有机物质积累增加。各气象因子共同作用组合成有利水稻高产的气象生态环境,促使水稻高产因素充分表达,使当地成为闻名世界的水稻超高产区。

Analysis of meteorological ecology for high yield of rice

The meteorological factors affecting the yield of rice are illuminance, temperat ure, precipitation and wind speed. In Taoyuan, Yunnan, there are sufficient dura tion and intensity of illumination, low daily mean temperature, significant day -night temperature difference, little precipitation, few raining days, and prope r wind speed which extend the growing period, increase the photosynthetic effici ency and promote the accumulation of organic matter in the rice. The joint-funct ions of various meteorological factors form a meteorological eco-environment fav ourable for the high yield of rice, which brings about the perfect expression of its high-yield factors. Thus this place has become a famous area for the high y ield of rice in the world.
