摘　　要：为明确不同植物调节剂在水稻上的应用效果,更好地发挥其增产增效的作用,本研究以“碧护”(0.136%赤·吲乙·芸苔可湿性粉剂,下同)和细胞酶叶面营养剂为试验材料,研究不同生育期处理对淮稻5号长势长相、产量和产量构成因素的影响。结果表明:与对照相比,在水稻不同时期喷施“碧护”和细胞酶叶面营养剂后可提高淮稻5号的植株长势、叶面积和叶绿素含量。叶面喷施“碧护”和细胞酶叶面营养剂的增产效果随着喷施次数的增加而增加;在返青期、拔节期、齐穗期均喷施1次叶面肥,水稻的千粒质量分别提高6.68%、5.87%,结实率分别提高3.71%、5.24%,产量分别增加8.98%、8.34%。对比2种不同的产品应用效果发现,喷施“碧护”的效果略好于细胞酶叶面营养剂。The current research was aimed to assess the effects of plant growth regulators on the growth and yield of the rice variety Huaidao No.5.We assessed the impact of two plant growth regulators:one was Bihu,which literally means’green protector’,containing 0.136%mixture of gibberellic acid,indoleacetic acid,and brassinolide;the other was a cell enzyme foliar nutrient agent containing trace elements.Spray-applied to the plants at different growth stages,they were evaluated for effects on plant growth vigour,yield,and yield components.The results indicated that the two foliage fertilizers improved plant vigour,leaf area,and chlorophyll content as compared with the control applied with water.Their stimulative effect on yield grew with increasing application times.Among all treatments with one to three applications of Bihu(at 30 g/hm^(2)in each application)or the cell enzyme foliar nutrient agent(at 600 m L/hm^(2)in each application),the treatment with three applications of a foliage fertilizer produced the most significant stimulative effects on rice growth and yield,and the three applications were arranged at the end of tillering stage,before the beginning of heading stage,and full heading stage.Under these conditions,Bihu and the cell enzyme foliar nutrient agent improved 1000-grain weight by 6.68%and 5.87%,respectively;setting rate by 3.71%and 5.24%,respectively;and final yield by 8.98%and 8.34%,respectively.The results also showed that Bihu is more effective than the cell enzyme foliar nutrient agent in promoting rice growth and improving yield.
