Abstract:
In order to select the best silage maize varieties suitable for popularization and planting in Qiqihar area, a randomized block design and membership function analysis were used to comprehensively evaluate the agronomic characters, production performance and nutritional quality of 12 silage maize varieties. The results showed that the whole growth period of 12 silage maize varieties was from 119 to 133 days, and all of them could reach the waxy ripening stage. Each trait index showed significant difference among varieties, and each single index of different varieties showed different performance, and each single optimal index did not gather in the same variety. Using fuzzy membership function analysis, the order of comprehensive performance of each variety was calculated as Jingke silage 205>Keqing No.1>Jinling Silage No.10>Zhongyuan Dan 32>Xianyu 335>Jinling Silage 377>Dica 159>Xinxin No.1>Shenyu 801>Beinong silage 3740>Jinyuan 15>Jingke silage 301. The results showed that Jingke silage 205, Keqing No.1 and Jinling Silage No.10 had the highest D value and showed good comprehensive characters, so they could be popularized in Qiqihar area.
