关于水稻和水层的关系,向来有两种不同的看法;第一种是认为水稻应当生长在有水层的水里;第二种是认为水稻不一定需要水层。我国多年来种稻几乎都是有水层的,有时由于水层过深而引起死苗,徒长,倒伏,病害等。因此为了将来深入研究水稻水分生理及合理灌溉问题,有必要首先了解不同水层深度对水稻生长和发育的影响。
There have always been two different opinions about the relationship between rice and the water layer. The first is that rice should grow in water with aquifers. The second is that rice does not necessarily need water. Over the years, almost all of our country has aquifers for rice, sometimes causing dead seedling, leggy, lodging, disease and so on due to too deep aquifers. Therefore, in order to further study rice hydrophyte and irrigation problems, it is necessary to understand the effects of different water depths on rice growth and development.
