湿润栽培对冷浸田水稻生长发育的影响

The Influence of Damp Cultivation on the Growth and Development of Rice in Cold and Soaked Fields

水稻冷浸田湿润栽培,改善了土壤的物理性状,提高土温2℃左右,从而促进了植株的生长发育;白根数、绿叶数和干物质量增加。尤其使抽穗扬花期及灌浆期的温度适宜,大大提高了水稻实粒数及有效穗数,使产量显著增加。

It was experimentally proved that the damp cultivation of rice in cold and soaked fields would improve the physical characters and types of soil and raise soil temperature by 2℃, so that the growth and development of plants would then be promoted and the white roots, green leaves and dry matters be increased in quantity. Especially, this made the temperature more adaptable at the stage of heading and flowering and the stage of being in milk, hence the rate of rice bearing and heading was greatly raised. This experiment resulted in a considerable increase of rice yield.
