水稻是湿生植物,它生长发育期间需要较多的水是尽人皆知的。水稻,水稻,有水才有稻。如果没有水或缺水,水稻是无法生长的,要夺高产那是更不可能的事了。 但是,水稻如果长期处在较深的水层里,也是不好的。尽管水稻生长在浅水中,根的皮层有相当一部分细胞会自行破毁消失,从而留下很大的气腔,贯穿在整个根部,并与茎叶内的通气系统相通,可以使氧气不断送到根部,从而能满足根部的呼吸。可是随着气温的逐步提高,到水稻生育中 Rice is a wet plant and it needs to be known that more water is needed during its growth and development. Rice, rice, water only rice. If there is no water or lack of water, rice can not grow, it is even more impossible to win the high yield. However, it is also not good for rice to stay in deep water for a long time. Although rice grows in shallow water, a considerable portion of the root cortex destroys and loses itself, leaving a large air cavity throughout the root and communicating with the ventilation system within the stem and leaves, allowing oxygen to be continuously delivered Root, which can meet the root of the breath. However, with the gradual increase in temperature, to the growth of rice
