摘　　要：为了分析中国化学调控技术对玉米的增产效果,本研究以喷施清水为对照,通过检索并筛选获得25篇有效文献,78组相关田间试验数据样本,将数据按照省/自治区、试验时间、玉米品种、种植密度、化控剂类型、喷施剂量和喷施期进行分组,利用Meta分析法定量研究中国化学调控技术对玉米的产量效应和影响因素。结果表明:应用化学调控技术可以有效提高玉米产量,平均增产量为570.489 kg/hm^(2),95%置信区间为413.595~727.382 kg/hm^(2),且数据不存在发表偏倚和极端值。选用紧凑型玉米高密度种植,在穗期喷施较低浓度化控剂,更有利于提高化学调控技术的增产效应。该研究可为化学调控技术应用提供参考。In order to analyze the effect of Chinese chemical control technology on maize yield increase.In this study,25 valid literatures and 78 groups of relevant field trial data samples were obtained by searching and screening with spray water as the control.The data were divided into groups according to province/autonomous region,experiment time,maize cultivar,planting density,chemical control agent type,spraying dose and spraying period.Meta analysis was used to quantitatively study the effects and influencing factors of Chinese chemical regulation technology on maize yield.The results showed that by using chemical regulation,maize yield could be increased effectively,average increasing yield being 570.489 kg/hm^(2) with no publication bias and no extreme values(95%confidence interval of 413.595~727.382 kg/hm^(2)).If compact maize is planted in high density and sprayed with low-concentration chemical regulator in panical stage,the yield increasing effect by chemical regulation will be enhanced.This study could work as a reference for application of chemical regulation.
