Effects of different combinations of pesticides on the growth and yield of fresh corn
Appropriate pest and disease control measures are important measures to achieve high yield,quality,and efficiency of fresh corn.To screened suitable seed dressing combinations for fresh corn,this experiment used fresh corn Nongkenuo 336 as the experimental material,and seted up four different combinations of pesticides combination 1(Beinong+Bihu),combination 2(Ruisheng+Beinong+Bihu),combination 3(Tiananfeng+Beinong+Bihu),and combination 4(Gaoqiao+Beinong+Bihu)and blank treatment(CK)to study the effects of different treatments on the emergence rate,seedling plant traits,and mature yield traits of Nongkenuo 336.The results showed that the emergence rate of Nongkenuo 336 mixed with different combinations of pesticides ranged from 88.50%to 96.67%,and combinations 2,3 and 4 had better emergence rates;Plant height and leaf length of maize seedlings in combination 1 and 4.The single fruit weight of Nongkenuo 336 mixed with different combinations of pesticides ranged from 183.05 to 198.33 g,while combinations 1 and 4 had higher single fruit weight.The fruit length ranged from 17.23 to 18.00 cm,and the fruit length of combination 4 was longer.The lowest disease and insect spike rate was found in combination 4,which was 15.35%.Overall,combination 4 had a higher emergence rate,better growth during the seedling stage,higher ear yield,lower disease and insect ear rate,and the best comprehensive resistance.It was suitable for promotion and application as a seed mixing combination agent for fresh corn.
