【目的】试验旨在筛选适合新疆和田垦区土壤条件、生物产量和经济效益高的青贮玉米品种，以供种植户选种参考。【方法】选择2个新疆选育和引进1个内蒙古选育的青贮玉米品种，通过对3个青贮玉米品种的农艺性状、抗性、产草量、效益的分析比较，筛选适宜推广的青贮玉米品种。【结果】新饲玉12号出苗至收获(蜡中期)131 d，株高310.50 cm，茎粗2.38 cm，抗倒伏性强，抗虫病性强，抗旱性强，生物产量92 464.95 kg/hm²，纯效益12 712.80元/hm²。WT171623和金岭386抗倒伏性强，抗旱性强，抗红蜘蛛等虫病性能较差，收获期分别为115 d和121 d，生物产量分别为63 865.20 kg/hm²和77 563.80 kg/hm²。【结论】新饲玉12号综合表现最为良好，适宜新疆和田垦区种植推广，但需要注意加强耕作、田间管理等技术研究，以提高整齐度。

【Objective】In order to screen a silage corn variety suitable for local soil condition and with high yields and economic benefits,so as to provide some reference for farmers in seed selection.【Methods】Two silage corn varieties bred in Xinjiang were selected and one variety bred in Inner Mongolia was introduced.Through comparison of the agronomic traits,resistance,forage yields and economic benefits of the three silage corn varieties,the one suitable for promotion was screened【.Results】For XINSIYU No.12 variety,the period from emergence to harvest(middle dough stage) was 131 days,with a plant height of 310.50 cm and a stem diameter of 2.38 cm.It had strong resistance to lodging,insect pests and diseases,and drought.The biological yield was 92 464.95 kg per hectare with the net profit of 12 712.80 yuan per hectare.For WT171623 and JINLING 386 varieties,they had strong resistance to lodging and drought,but poor resistance to insect pests and diseases such as red spider mites,the harvest periods were 115 and 121 days respectively,and the biological yields were 63 865.20 and 77 563.80 kg per hectare respectively.【Conclusion】XINSIYU No.12 showed the best comprehensive performance and was suitable for planting and promotion in Hetan reclamation area.However,it was necessary to pay attention to strengthening the technical research on cultivation,field management,etc.,so as to improve the uniformity of crops.
