| 摘 要： | 通过对旱育秧和水育秧进行比较研究，结果表明：（１）旱育秧较水育秧增产４．９％，增产显著，增产途径是多穗；（２）形态上，旱育秧苗移栽叶龄小，叶片小，分蘖少，叶鞘长，植株高；（３）生理上，旱育秧苗叶鞘积累的干物质多，叶片比叶重大，根系氧化能力强，束缚水和脯氨酸含量高，而叶绿素和丙二醛含量低

| Abstract: | A comparative study was conducted between dryland-raised seedlings (DRS) and wetland-raised seedlings (WRS). The results were as follows: (1) The grain yield of DRS was higher significantly than WRS by 4.90%, which resulted from the increase of effective panicles; (2) Morphologically, the number of leaves of seedling (leaf age) of DRS was smaller, leaf area per leaf and per plant were smaller, tillered seedlings were fewer, leaf sheath was longer and plant was higher; (3) Physiologically, leaf sheath of DRS accumulated more dry matter, specific leaf weight was greater, root oxidizing capacity was stronger, contents of bound water and proline were higher, but contents of chlorophyll and MDA were lower. |
