摘要
采用田间试验及大田示范方式研究了4种化学调控剂(玉米矮丰、玉黄金、乙烯利、金得乐)不同浓度对夏玉米生长发育、抗倒伏能力及产量的影响,明确了化学调控剂对夏玉米生长发育的效果,以期为提高夏玉米抗倒伏能力、实现夏玉米高产和稳产提供理论和技术依据。结果表明,施药浓度越高,抗倒伏能力越强,对夏玉米生长发育的影响越大,1.5倍化学调控剂推荐浓度(化学调控剂标签上所注明的施用浓度)较好地平衡了提高抗倒伏能力和抑制玉米生长的关系,且产量最高。
In order to define the effect of chemical regulator on summer maize production,and to provide theoretical and technical basis for increasing lodging resistance and getting high yield of summer maize,field trial and field demonstration were conducted at the same time to study the effect of four chemical regulators（summer Aifeng, Yu Huangjin,Ethephon and Jindele） with different concentrations on growth, lodging resistance and yield of summer maize. The results showed that the higher the concentration of the chemical,the better the lodging resistance,the greater the effect on the plant growth of summer maize. 1.5 times of the recommended concentration that was indicated on the label of the chemical regulators could balance the relationship between the improvement of lodging resistance and the inhibition of the growth of maize, and achieve the highest yield.
