一、大豆引种的重要性大豆是人们日常生活的重要副食品和食品工业原料,五十年代中后期,全省大豆面积在400万亩左右,1957年曾达456万亩。近十余年来,我省大豆种植面积大大下降,一直徘徊在200万亩左右。一般亩产120斤上下,低的只有30—50斤。大豆单产低的原因很多,其中品种不良,是一个重要因素。近年来,我省通过引种试验,鉴定和筛选出一批适宜我省栽培的大豆良种,如“矮脚早”、“六月白”、“五月拔”等,已在丰城、进贤、高安等县大面积推广,取得了显著的增产效果。例如进贤县1982年推广“矮脚早”25,000余亩,一般亩产200～250斤,比当地品种茶豆每亩增产40～100斤。大豆是一种对光照反应敏感的作物,不经试种,盲目推广外来品种,容易招致失败。如清江、丰城等县从福建引进早大豆品种
First, the importance of the introduction of soybean Soybean is an important non-staple food and food industry daily raw materials, the mid-and-late 1950s, the province’s soybean area of 400 mu, 1957 had reached 4.56 million mu. In the past ten years or so, the area under soybean cultivation in our province dropped significantly, hovering around 2 million mu. General per mu 120 pounds up and down, low only 30-50 pounds. Soybean yields low for many reasons, including poor varieties, is an important factor. In recent years, our province through the introduction of tests, identification and screening of a number of soybean cultivars suitable for cultivation in our province, such as “Bantam early”, “June white”, “May pull” and so on, Fengcheng, Jinxian , Gao An County and other large-scale promotion, and achieved remarkable yield increase. For example, Jinxian County in 1982 to promote “Banthor early” more than 25,000 acres, the general mu produce 200 ~ 250 pounds, than the local varieties of tea beans yield 40 to 100 pounds per mu. Soybeans are a kind of crops that are sensitive to light and can easily lead to failure if they are blindly popularized without test species. Such as Qingjiang, Fengcheng county from Fujian introduced early varieties of soybeans
