近年来,随着我国人民生活水平的逐年改善与提高,用于转化为肉、禽、蛋、奶、鱼的饲料粮,其用量、比重越来越大,问题也越来越突出。因此,应加强高产饲料作物的研究。我国一些省份农村有用谷物喂猪的习惯,有一些稻麦品种产量高,如特青2号稻、克旱9号小麦,但因品质差,人们不愿吃,种植面积也下降。过去,玉米、高粱是东北人的主要食粮,现在被面粉、大米代替。玉米、高粱是高产作 In recent years, as the standard of living of our people has been improved and improved year by year, the amount and proportion of feed grains used for conversion into meat, poultry, eggs, milk and fish have become larger and larger, and the problems have become increasingly prominent. Therefore, research on high-yield forage crops should be strengthened. Some provinces in our country have the habit of feeding useful grains in rural areas. Some rice varieties have high yields, such as Teqing No.2 rice and Khan No.9 wheat. However, due to poor quality, people do not want to eat and the area under cultivation has also dropped. In the past, corn and sorghum were the staple foods of northeastern China and were now replaced by flour and rice. Corn, sorghum is high yield
