通过稻田小气候与水稻生长发育的平行观测,探索水稻优质高产的田间小气候特征,分析表明,稻田小气候效应,符合局部气候原理和田间小气候基本规律。在采用岗优22组合,密度2.25万窝/hm~2的稻田里,生长发育的关键期—抽穗开花期,能形成更为合理的田间小气候,水温、地温和气温配合较优,光照较好,有利于CO_2的输送,增强了光合作用和有机质的积累,因而对光能的利用率较高,能达到10410kg/hm~2的产量。但根据当年的光、热、水条件和生产水平要素估算,生产潜力可达13558.5kg/hm~2。
Through the parallel observation of paddy field microclimate and rice growth and development, the microclimate characteristics of high quality and high yield paddy field were explored. The analysis showed that the microclimate effect of paddy field accorded with the local climate principle and the basic law of field microclimate. In the paddy field with Gangyou 22 combination and density of 22.5 thousand litters / hm ~ 2, the key stage of growth and development - heading and flowering stage can form a more reasonable field microclimate, the water temperature, the temperature and temperature are better, the light Better, it is conducive to the transport of CO2, enhanced photosynthesis and accumulation of organic matter, so the utilization of light energy is higher, can reach 10410kg / hm ~ 2 production. However, based on the current year’s light, heat and water conditions and production levels of elements estimated that the potential for production up to 13558.5kg / hm ~ 2.
