摘　　要：以籼稻品种扬稻6号、粳稻品种宁粳1号为材料,通过盆栽试验,利用人工温室,研究营养生长期高温处理对水稻生长的影响。结果表明,营养生长期高温处理促进了水稻的生长,经增温处理,试验品种株高、茎蘖数、叶面积、地上部干物质量均明显增加,但叶龄、叶片叶绿素含量没有发生明显的变化,其中,籼稻品种扬稻6号受高温的影响更加明显。A experiments was carried out to study the effect of high temperature at vegetative stage on rice growth, using Ningjing 1and Yangdao 6 as materials. The results showed that the high temperature stress during vegetative growth stage to promote the growth of rice, the plant height, leaf area, leaf width, leaf length, tiller numbers and dry weight of rice increase. But the leaf age, leaf chloro-phyll content does not take place obvious change. Indica rice variety Yangdao 6 is affected more obvious by high temperature.
