以湘晚籼17号为材料,利用缓释氮肥研究了带肥抛秧对水稻秧苗素质、生育期、农艺性状及产量的影响。结果表明:带肥抛秧可明显提高湘晚籼17号的秧苗素质,促进水稻生育前期根系的生长以及分蘖的早发、多发;同时,带肥抛秧还可延长湘晚籼17号生育期2～4d;在产量方面,由于带肥抛秧提高了水稻的有效穗数和每穗实粒数,产量显著提高,其中产量以施用氮肥20 g/盘的处理最高,达497.4 kg/667 m2,比对照增产14.1%。
With Xiangshenxian 17 as material, the effects of fertilizer-treated rice throwing seedlings on quality, growth period, agronomic traits and yield of rice seedlings were studied using slow-release nitrogen fertilizer. The results showed that the seedling throwing with fertilizer could significantly improve the seedling quality of Xiangshenxian 17 and promote the root growth and early tillering and tillering of rice at the early stage of rice growth. Meanwhile, the seedling throwing seedling could also prolong the growth period of Xiangsanxian 17, 2 ~ 4d. In terms of yield, the yield was significantly increased due to the increase of panicle number per panicle and seed number per panicle with paddy throwing seedling, and the highest yield reached 497.4 kg / 667 m2 , 14.1% more than the control.
