Effect of chemical regulators on plant growth and yield of maize variety Luning 184 for grain and forage
Maize lodging caused by extreme weather will seriously affect the harvest yield of maize for both grain and forage.The growth characteristics and yield formation of the grain-forage maize variety Luning 184 under different chemical regulators treatments were investigated by using four chemical regulators and spraying water as the control.The results showed that compared with the control,different chemical regulators could effectively adjust the growth traits of maize,mainly reduce plant height,increase the number of secondary roots to enhance lodging resistance,and spraying paclobutrazol or amine fresh ethephon treatment could increase the yield of fresh and dry weight of plants,maintain a higher number of grains per panicle,and achieve the purpose of increasing yield and resistance,which was recommended to be used in production.
