| 摘 要： | 为明确影响晚稻秧苗素质及产量性状的因素,以湖南省优质晚稻玉针香为材料,研究不同播种量、基质和药剂处理对水稻秧苗素质及产量性状的影响。结果表明：⑴播种量150g/盘与125g/盘和175g/盘相比,其苗高适中,秧苗茎基宽和地上部鲜重较大,单株平均分蘖数相对较多,且秧苗移栽后的结实率最高,单株产量最大,具有高产、稳产的潜力;湘晖基质的壮秧、增穗、增产效果优于田土。⑵整体而言,配方I药剂（30L水对1包25%有效成分含量的咪鲜胺和3包5%有效成分含量的烯效唑混合）浸种后不清洗种子,以及播种前于秧盘内的麻育秧膜上喷施配方II药剂（配方I药剂和40g尿素混合）,秧苗健壮度较高,分蘖能力较强,且秧苗移栽后的单株有效穗数和结实率高于其他药剂处理育秧方式,单株产量最大。

| Abstract: | In order to clarify the factors affecting the seedling quality and yield characters of rice, the effects of sowing amount, seedling raising medium and chemical treatment on seedling quality and yield characters were studied in this experiment. The sowing amount of 150g per disk had moderate seedling height, larger stem base width of seedling and shoot fresh weight, more numbers of tillers and the highest seed setting rate, largest yield per plant compared with that of 125g per disk and 175g per disk, and it had good potential for high yield and stable production. In addition, the seedling raising, spike and yield increasing effect were better by Xianghui medium than by field soil. (2)Under the treatment of soaking seed and no washing with formula I (30L water mixed with 1 package of Prochloraz containing 25% effective components and 3 packages of Uniconazole containing 5% effective components) and spraying the solution of formula II (mixture of formula I and 40g urea) on bast fiber film before sowing, the seedlings had higher robustness and stronger tillering ability, panicle number per plant and seed setting rate were more than the other agents treatment, and single rice plant had the greatest yield after transplanting. |
