摘要
不同灌溉方式下水稻乳苗撒播成苗情况研究结果表明,无水层带泥浆撒播处理,根系发育与茎叶生长比较协调,成苗率达90.7%,秧苗综合性状好于其他处理,是水稻乳苗抛秧的首选方式;淹水48h后落干处理,有利于发根和扎根立苗,成苗率达92.7%,秧苗综合性状较好,是水稻乳苗抛秧应采用的第2种方式。
The seedling office nurseling-seeding-scattefing in different irrigation methods were studied.The results showed that the treatment of spreading in mud layer without water had a higher rate of seedhng which reached 90.7%, the growth of root, stem and leaf was harmony, and seedling traits were better than the other treatments. So it was the preferred way office nursehng-seeding-scattering. The treatment of drop-dry after flooding for 48 hours was conducive to root development,which had a higher rate of seedling reaching 92.7% ,and seedling had better comprehensive characters, so it was the second approach that should be adopted in rice nursehng-seeding-scattering.
