摘要
我国是世界玉米生产大国之一,推广种植青贮玉米对畜牧业生产具有重要作用。为了更好地了解我国青贮玉米生产状况,有必要对其品种、产量及与品质有关的研究报道进行归纳、总结。研究表明,我国青贮玉米种植地区主要分布在黑龙江、京津周边地区、内蒙古,宁夏、四川、浙江和福建分布较少;适合不同地区种植的青贮玉米品种至少有68种,其干物质产量为16.1～28.5t/hm2,粗蛋白质(CP)含量为7.69%～8.42%,中性洗涤纤维(NDF)和酸性洗涤纤维含量(ADF)分别为55.30%～84.99%和30.34%～49.31%。该结果有助于指导我国奶牛养殖户发展全株青贮玉米生产,也可为我国各地区制订青贮玉米种植规划提供参考资料。
China is one of the largest corn production countries in the world and the planting of forage corn plays an important role in animal husbandry production. In order to better understand the production status of forage corn in China, it is necessary to review the relevant studies on its species, yield and quality. The results showed that the planting area of forage corn was mainly distributed in Heilongjiang Province, Beijing and surrounding areas, Tianjin and surrounding areas,and Inner Mongolia, but it was little distributed in Ningxia, Siehuan, Zhejiang and Fujian. More than 68 varieties/species of forage corn were suitable for planting in different regions. The dry matter yield was 16.1-28.5 t/hm2,crude protein （CP） was from 7.69% to 8.42% , and neutral detergent fiber （NDF）and acid detergent fiber （ADF） were 55.30%-84.99% and 30.34%-49.31% respectively. The results will help dairy farmers to develop the production of whole-plant forage corn and will provide references for making plans of planting forage corn in different regions of China.
