摘要
2005年早稻进行奇茵植物基因活化剂施用对比试验,结果表明:分蘖期喷施奇茵,对产量影响不大;而孕穗期、齐穗期喷施奇茵,结实率明显提高,平均公顷产量分别增加366kg和303 kg,增幅分别为5.6%和4.7%。
Comparison experiment of plant gene activator Qiyin was conducted on early rice in 2005. The results showed that it had no significant effect on rice yield applied Qiyin at tillering stage, but it could increase seed setting rate obviously applied at ear pregnant stage and full heading time, and the yield of per hectare was averagely increased 366kg and 303kg with increase rate of 5.6% and 4. 7%, respectively.
