摘要:
青贮玉米以营养丰富,生产成本低、贮藏期长等优势被誉为“饲料之王”,内蒙古赤峰市是畜牧业发达的地区,为了缓解饲草需求量逐步增加的问题,筛选出适于赤峰市中早熟区优质高产的青贮玉米品种是非常有必要的。本研究以先玉335作为对照品种,以沈玉801、利禾1号等33个玉米品种作为参试品种,对比各品种生育期、农艺性状、鲜草产量、干物质产量以及籽粒产量。结果表明, 沈玉33、利禾1号、京科青贮205适宜赤峰地区青贮玉米种植。

Abstract:
Silage corn is known as the “king of feed” because of its nutrient-rich, low production cost and long storage period. Chifeng City in Inner Mongolia is a developed area for animal husbandry. In order to alleviate the problem of increasing demand for forage, it is suitable for Chifeng. High-quality and high-yield silage maize varieties in the early-maturing areas of the city are very necessary. In this study, Xianyu 335 was used as a control variety, and 33 maize varieties including Shenyu 801 and Lihe 1 and many more were used as test varieties to compare the growth period, agronomic traits, fresh grass yield, dry matter yield and grain yield of each variety. The results show that Shenyu 33, Lihe.1 and Jingke Silage 205 are suitable for silage corn planting in Chifeng.
Key words:  Corn variety  silage screening  fresh grass yield  dry matter yield  grain yield
