| 摘 要： | 以南粳9108为试验材料,研究稀播条件下(18000苗/m2)不同措施对30、35 d秧龄秧苗素质的影响。结果表明:在18000苗/m2的播种密度下,多效唑浸种能够有效地促进根系生长,矮化秧苗高度,显著提高秧苗素质,对于培育不同秧龄的壮苗均有促进作用。多效唑浸种浓度在0.5 g/L左右最为适宜。

| Abstract: | Using the rice variety Nangeng 9108 as the experimental material,the present study investigated the effects of different agronomic measures on the seedling quality of 30-and 35-day-old seedlings under the condition of thin sowing(18000 seedlings/m2).The results showed that when rice was planted at the density of 18000 seedlings/m2,soaking seeds in paclobutrazol effectively promoted root growth,reduced the height of seedlings,and significantly improved the quality of seedlings,thereby promoting the culture of robust seedlings at different ages.The paclobutrazol concentration at about 0.5 g/L is most suitable for soaking rice seeds. |
