Evaluation of agronomic traits,nutritional components,and economic benefits of different silage corn varieties in shandong region
This experiment aims to study the agronomic traits,nutritional components,and economic benefits evaluation of different silage corn varieties in Shandong region.Seven types of silage corn(Jingke silage 516,Siyu 1,Yuqing 386,Beinong silage 208,Yulong 709,Qingyou 90,Guiqingsilage 1)were selected as the research objects.Each type was planted in three repeated plots(30 m2),and under the same climate conditions,planting density,and field management,the agronomic characteristics of silage corn were measured.After harvest and drying,the nutritional components were measured,and the economic benefits were calculated based on yield.The results showed that:(1)The plant height of silage corn from Siyu 1,Yuqing 386,Beinong Qingsilage 208,and Yulong 709 was significantly higher than that of Jingke Qingsilage 516,Qingyou 90,and Guiqingsilage 1(P＜0.05);The fresh and dry weight of silage corn from Siyu 1,Yuqing 386,and Beinong Silage 208 were significantly higher than those from Jingke Silage 516,Yulong 709,Qingyou 90,and Guiqingsilage 1(P＜0.05);In terms of yield,Yuqing 386 silage corn has the highest fresh and dry weight,which are 65508.22 kg/hm2 and 18512.34 kg/hm2,respectively;The fresh and dry weight of silage corn from Siyu No.1 came second,with 64876.25 kg/hm2 and 18247.39 kg/hm2,respectively.(2)The crude protein content of Qingyou 90 silage corn was significantly higher than that of Jingke silage 516,Siyu 1,Yuqing 386,Beinong silage 208,Yulong 709,and Guiqingsilage 1(P＜0.05);The neutral washing fiber content of silage corn from Siyu 1,Yuqing 386,and Yulong 709 was significantly higher than that of Qingyou 90(P＜0.05);The acid washing fiber content of Beinong silage 208 and Qingyou 90 silage corn was significantly higher than that of Siyu 1(P＜0.05);The crude fat content of corn silage from Beinong silage 208,Qingyou 90,and Guiqingsilage 1 was significantly higher than that of Jingke silage 516,Siyu 1,Yuqing 386,and Yulong 709(P＜0.05).(3)The economic benefits of seven silage corn varieties are 21047.17 yuan/hm2,22706.69 yuan/hm2,22927.88 yuan/hm2,22510.33 yuan/hm2,21435.32 yuan/hm2,19173.91 yuan/hm2,and 14765.56 yuan/hm2,respectively.From the perspective of economic benefits alone,the highest value is Yuqing 386,followed by Siyu 1.Conclusion:Under the conditions of this experiment,the yield and economic benefits of Siyu 1 and Yuqing 386 were the best,making them suitable for promotion and planting in Shandong region.
