玉米化控技术的作用及使用要点

The Function and Main Points of Application of Maize Chemical Control Technology

合理增加群体密度是保障玉米增产稳产的重要途径。在适度增密的同时,化控技术的应用可以有效降低由于种群密度增加而带来的倒伏风险。化控剂对玉米产量、质量构成要素、农艺性状以及光和性能都有不同程度的影响,化控剂施用剂量和时期掌握不当不仅不会起到抗倒作用,反而会影响玉米的生长。因此,明确化控技术的作用以及科学合理使用化控技术是十分重要的。

Reasonable increase of population density is an important way to ensure maize yield increase and stable yield.At the same time of moderate densification,the application of chemical control technology can effectively reduce the lodging risk caused by the increase of population density.Chemical control agents have different degrees of influence on corn yield,yield components,agronomic characters,light and performance.Improper dosage and period of chemical control agents will not have anti-reverse effect but will affect the growth of corn.It is very important to clarify the role of chemical control technology and make scientific and rational use of chemical control technology.
