Screening of different silage maize varieties in Qingshui area
The purpose of this study was to screen out silage maize varieties suitable for cultivation in Qingshui area.A total of 12 maize varieties were selected for the experiment,and the biological yield and agrologic traits of each variety were compared,and the Grey Model theory was used for comprehensive evaluation.The experiment used a randomized block design with three replicates for each variety.The results showed that the fresh grass yield of Tieyan 53,SN211 and Fengzhu No.1 was more than 90.00 t/hm2,among which Tieyan 53 had the highest fresh forage yield(103.08 t/hm2)and dry matter yield(34.50 t/hm2),and its leaf weight was significantly higher than that of other varieties(P＜0.05).The ear weight of Dongdan No.13 was the highest,but the biological yield was not high.The variety with the highest plant height was G19-2,the variety with the greatest stem diameter was Tieyan 53,and the variety with the most number of green leaves was SN211.The application of the grey relational analysis method in a comprehensive comparison of 12 maize varieties showed that the top three are Tieyan 53,SN211,and Fengzhu No.1.The research indicates that Tieyan 53,SN211,and Fengzhu No.l exhibit good agronomic traits and are suitable for promotion and cultivation in Qingshui area.
