摘　　要：以水稻品种垦研017为试验材料,设一次性浇施、二次浇施、多次浇施3个处理,探讨不同肥料用量及施用次数对秧苗素质的作用效果。结果表明:不同处理的秧苗茎基宽、1叶长宽表现较稳定;增加施肥次数,降低施肥浓度,1叶长、2叶长、3叶长各处理间无明显变化,但2叶、3叶变窄,少量多次的施肥方式对秧苗后期的伸长生长具有控制作用;一次性浇施不利于1叶、2叶、3叶、1叶鞘、1~2叶耳距、根干重的形成,根干重占比仅为12.8%;二次浇施秧苗地上及根干重最高,根干重占比为22.2%;多次浇施利于秧苗根系发育,但地上部生长量偏低。二次浇施能够实现秧苗地上各部分与根系的协调生长,对壮苗的形成具有促进作用。Rice cultivar Kenyan-017 was used as experimental material to investigate the effects of different fertilizer dosage and application times on seedling quality by one-time pouring,two-times pouring and multiple pouring treatments.The results showed that the stem base width and the first leaf length-width of seedlings under different treatments were stable.With the increase of fertilization times and the decrease of fertilization concentration,there was no significant change in the first leaf length,the second leaf length and the third leaf length,but the second leaf length and the third leaf length narrowed.One-time watering was not conducive to the formation of the first leaf,the second leaf,the third leaf,the first sheath,the 1-2 ear distance and the dry weight of root,and the proportion of dry weight of root was only 12.8%.The ground and root dry weight of the seedlings were the highest after two-times pouring,and the proportion of root dry weight was 22.2%.Multiple watering was beneficial to root development of seedlings,but the above-ground growth was low.Secondary watering can realize the coordinated growth of each part of the seedling and the root system,and promote the formation of strong seedlings.
