The study was to select suitable silage maize varieties for planting in the western region of Heilongjiang. The agronomic traits, biomass and nutritional quality of 28 varieties were comprehensively evaluated in this experiment by membership function method. The results showed that the highest plant height was Yu Silage 23, which was 340.10 cm. The highest ear position was Silage 5102, which was 161.60 cm. The highest hay yield was M115S with 25 724.23 kg/hm2. The crude protein, starch, acid detergent fiber and neutral detergent fiber contents of the 28 participating varieties ranged from 6.75% to 9.21%, 17.90% to 27.99%, 20.81% to 28.38% and 42.86% to 56.94%. Comprehensive analysis of 28 major agronomic traits, biological yield and nutritional quality of silage maize by the subordinate function method showed that Meng Silage 266, M114D, Bei Silage 1, Yu Silage 23, and Zhongdan Silage 29 were outstanding in the western Heilongjiang region, and were suitable for popularization of planting in this region and areas with similar climatic environments.

The experiment based on nine different varieties of forage sorghum species, the fertility period, major agronomic traits, yield and nutrients were measured to determine the adaptability of the tested varieties in Qiqihar. The results showed that the phenological period of each variety was different, and the tested varieties failed to complete the whole growth period. The tested variety with the largest stem diameter was Dalishi (20.86 mm), the tested variety with the largest hay yield was 12FS0018 (33 765.71 kg/hm2), the tested variety with the highest crude protein content was Dalishi, the tested varieties with the least acid detergent fiber content was Longtian No.1, the tested varieties with the least neutral detergent fiber content was 12FS0018, the highest relative feeding value was Longtan 1, and the lowest was Hulk. Only the tested variety Niumowang had brown midrib. The study indicates that the nine tested varieties have good adaptability in Qiqihar, and different purpose can be selected according to different production goals. [ABSTRACT FROM AUTHOR]
