Identification and Evaluation of Production Performance of 14 Silage Corn Varieties in Yan'an area
摘要
Abstract
In order to select the suitable corn silage varieties for planting in Yan'an area,14 varieties were selected as the research objects,and the growth period,agronomic characters and production performance of different varieties were compared through field experiments,and the membership function method was used to comprehensively evaluate each variety.The results showed that the 14 maize varieties planted in spring in Yan'an area were all able to harvest in time.The coefficient of variation of 7 agronomic traits was 6.62%-56.22%,the variation of leaf traits was larger,and the variation of ear traits was smaller,among which Dajingjiu Silage 3912,Jingang Silage 50 and Yayu Silage 26 showed better agronomic traits.The productivity per plant of Jingang Silage 50 was significantly higher than that of other varieties,and the fresh and dry weight per plant reached 1 475.00 and 523.59 g,respectively.Beinong Silage 208 and Jingang Silage 50 had higher yields,with fresh grass yields of 58.69 and 57.20 t/hm2 and hay yields of 21.40 and 20.30 t/hm2,respectively.The top 2 varieties were Jingang Silage 50 and Beinong Silage 208 by membership function method.In conclusion,Jingang Silage 50 and Beinong Silage 208 have better comprehensive pro-duction performance and are suitable to be popularized as silage maize varieties in Yan'an area.关键词
