Heilongjiang is the largest province of maize cultivation in China.Maize is an important raw material crop in China's grain and feed industry,which plays an important strategic role in China's food security.In recent years,a lot of progress has been made in maize chemical control production.The chemical control of maize production has made a lot of progress,is the main means of plant growth regulators,using chemical control technology to change the physiological,characteristics of maize,In order to solve the problem of maize production,physiological regulation is carried out to a certain extent.In this experiment,a new chemical control agent of corn,WuGu FengSu,was used,and "Tiannong 9" corn was used as the experimental material.Four different concentrations of WGF chemical control agents were applied to maize at different growth stages by spraying.The results showed that:1.The plant height and ear height of maize decreased obviously after spraying chemical control agent WGF,In all growth stages of maize,the height of center of gravity decreased,the stem base thickness,stem bending strength and puncture strength increased under different treatments.The internode length of maize was significantly shortened,and the change of morphological characters of maize improved the lodging resistance of maize stalk.Among the treatments,the effect of W2 treatment on maize agronomic characters was the most obvious.2.After spraying chemical control agent WGF,the leaf area of photosynthesis increased,the content of chlorophyll increased,the activity of PEPc and RuBPc increased,the net photosynthetic rate increased,and the dry matter weight decreased,which promoted the photosynthesis and metabolism of maize.The effect of W2 treatment on the light and characteristics of maize was the most obvious.3.After spraying chemical control agent WGF,the corn crude protein,crude fat and crude starch were increased,and the water content of corn decreased,and the effect of W2 treatment on maize quality was the most obvious.4.After spraying chemical control agent WGF,the effective ear length,the number of grains per row and the 100 kernel weight of corn were increased significantly,and WGF accelerated the filling rate of maize,and increased the yield of maize by increasing the grain plumpness.Among the treatments,the effect of W2 treatment on maize yield was the most obvious.
