中文摘要：试验选取雅玉青贮8号(3号)、文玉3号(4号)、曲辰19号(6号)3种青贮玉米品种进行种植,研究不同青贮玉米品种在湛江地区的农艺性状和营养成分,挑选适宜在湛江地区种植的青贮玉米品种。结果表明:3种青贮玉米品种均能正常生长。3号品种产量最高,达到51 675.64 kg/hm^2。4号品种蛋白(CP)含量最高,为10.26%;可溶性多糖(WSC)含量最高,可达5.41%;中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)均最低,分别为40.32%、20.16%;相对饲喂价值(RFV)最高,为205.06。钙、磷含量从高到低依次为6号、4号、3号。综合评价得出,4号品种适合在湛江种植。

外文摘要：Three silage maize varieties, Yayu silage 8(No. 3), Wenyu 3(No. 4), and Quchen 19(No. 6) were selected for planting to study the agronomic characteristics and nutrition of different silage maize varieties in Zhanjiang area. The results showed that: all the silage maize varieties could grow normally. The yield of No.3 maize was the highest(P<0.05), reaching 51 675.64 kg/hm^2. The content of crude protein(CP) of No.4 maize was the highest(10.26%). The content of WSC of No. 4 was up to 5.41%. NDF and ADF of No. 4 were the lowest, which were 40.32% and 20.16%, respectively. RFV of No. 4 was the highest at 205.06. The contents of calcium and phosphorus were No.6, No.4 and No.3 from high to low. The comprehensive evaluation showed that No.4 variety had the best adaptability in Zhanjiang.
