| 摘 要： | 通过大田小区试验,研究了不同时期叶面喷施硒植物营养素对超级稻(Y两优1号)产量和稻米中硒含量的影响.结果表明:在分蘖盛期、始穗期前3 d和灌浆初期各喷施一次750倍水稻型富硒植物营养素的处理产量最高,达到11 317.55 kg/hm2,比对照处理增产865.15 kg/hm2,增产率达到8.28%;其稻米硒含量高达0.74 mg/kg,与其他处理之间差异均达到极显著水平.在灌浆初期喷施一次750倍水稻型富硒植物营养素的处理产量次之,为11 139.65 kg/hm2;其稻米硒含量高达0.72 mg/kg. |
| 关 键 词： | 叶面喷施 富硒植物营养素 产量 硒含量 |

| Abstract: | A field experiment was conducted to study the effects of foliage spraying selenium-nutrients at different periods on yield and se-content of super rice(Yliangyou 1).The results showed that when spraying a 750-fold rice-based se-nutrient once at tillering stage,three days before heading stage and early filling stage respectively,the yield of rice was the hishest that reached 11 317.55 kg/hm2;compared with control,the yield of rice increased by 865.15 kg/hm2,and the increaSing rate was 8.28%:the se-content in rice reached 0.74 mg/kg,and there was a extremely significant difference between this treatment and the others.When spraying a 750-fold rice-based se-nutrient once at early filling stage,the yield of rice was worse than the above treatment that was 11 139.65 kg/hm2.but the se-content in rice reached 0.72 mg/kg. |
