1.技术简介开发稻谷资源应包括2个方面内容:一是选育蛋白质含量高、产量高,适于用作饲料的水稻新品种;二是使国家库存积压的稻谷得到充分利用。稻谷生产主要集中在南方各省。其中江苏、浙江、安徽、江西、湖北、湖南、广东、广西、四川等9个省区的稻谷产量占全国的70%以上。这种粮食生产区域分布限制了部分省饲料工业的发展,由于玉米等饲料原料的主要产地是在北方,而猪肉主要产地在南方,这就造成北方生产的玉米大量积压,而南方的玉米严重不足。我国早籼稻(米)替代玉米作配合饲料的工作刚刚 1. Introduction to technology Development of rice resources should include two aspects: First, breed high protein content, high yield, suitable for use as a feed new varieties of rice; the second is to make full use of national inventory backlog of rice. Rice production is mainly concentrated in the southern provinces. Among them, rice production in nine provinces and autonomous regions including Jiangsu, Zhejiang, Anhui, Jiangxi, Hubei, Hunan, Guangdong, Guangxi and Sichuan accounted for more than 70% of the national total. This distribution of food production limits the development of the feed industry in some provinces. Since the main origin of feed ingredients such as corn is in the north and the main origin of pork is in the south, there is a large backlog of corn produced in the north and a significant shortage of corn in the south .
