水稻的干物质约有90—95％,是其利用太阳的光能,通过光合作用、将从叶面吸收的CO_2和从根部吸取的水合成碳水化合物。而其它生态条件则强烈地影响着干物质的累积和运转。因此,利用水、肥调节水和生育进程,最大限度地利用太阳光能,提高光合作用效率,是增加水稻单位产量的一项重要技术措施。
About 90-95% of dry matter in rice is the light energy of the sun that uses it to photosynthetically absorb CO 2 absorbed from the foliage into water and carbohydrates absorbed from the roots. Other ecological conditions strongly influence the accumulation and operation of dry matter. Therefore, the use of water and fertilizer to regulate water and fertility, to maximize the use of solar energy and improve photosynthesis efficiency is an important technical measure to increase unit output of rice.
