摘　　要：以南粳9108为材料,始穗期通过喷施劲丰(1.5 L/hm2)、碧护(60 g/hm2)、矮壮丰(675 g/hm2)、磷酸二氢钾(750 g/hm2)、赤霉酸(15 g/hm2)处理,比较研究生化试剂对毯苗机插和钵苗机插水稻产量及生理生态特征的影响。结果表明,矮壮丰、磷酸二氢钾、碧护处理后的水稻抽穗后叶面积大,干物质积累多,群体生长率、光合势显著高于对照。喷施矮壮丰能够显著增加穗粒数、结实率和千粒重,两种机插方式实产分别较对照增加12.71%和10.39%,可有效缓解水稻生育中期持续低温阴雨天气的不利影响。钵苗机插稻后期群体生长优势明显,光合物质积累多,较毯苗机插平均增产6.95%,有利于抗逆减灾和大面积平衡高产。Using Nanjing 9108 as the experimental material, setting different treatments by spraying 1.5 L/hm2 Jingfeng, 60 g/hm2 bi- hu, 675 g/hm2 Aizhuangfeng, 750 g/hm2 potassium dihydrogen phosphate, 15 g/hm2 gibberellic acid to study the effects of these treat- ments on rice yield, physiological and ecological characteristics of blanket seedling mechanical- transplanting rice and nutrition bowl mechanical-transplanting rice. The results showed that aizhuangfeng, potassium dihydrogen phosphate and bihu can increase the rice yield. Aizhuangfeng increases the grain number per spike, seed setting rate and 1 000-grain weight significantly, the rice yields of the two mechanical- transplanting methods are 12.71% and 10.39% higher than the contrast respectively. The nutrition bowl mechanical- transplanting rice has an advantage in the population growth at anaphase and has more dry matter. The yield of nutrition bowl mechan- ical- transplanting rice is 6.95% higher than blanket seedling mechanical- transplanting rice on average.
