山西大豆品种资源丰富,类型繁多。我们于1974—1980年对大豆品种及生态型进行了研究,将山西省765份不同类型的大豆品种在同一地区、同一生态环境、同一栽培管理条件下种植,所获得的结果加以分析,就生育期的地理分布而言,大致可以代表北方春大豆型及部分夏大豆的生态类型。生育期是品种适应性最主要的标志之一,生育期的长短直接关系到产量的高低及它在栽培制度中的地位和作用。生育期只有符合当地的自然条件、耕作栽培制度,才能正常生长发
Shanxi soybean varieties rich in resources, many types. In 1974-1980, we conducted a study of soybean varieties and ecotypes, and analyzed the results of 765 different types of soybean cultivars grown in the same area, the same ecological environment and the same cultivation and management in Shanxi Province, In terms of the geographical distribution of the period, it can roughly represent the ecological type of the northern spring soybean and some summer soybean. The growth period is one of the most important indications for the adaptability of varieties. The length of the growth period is directly related to the level of output and its status and role in the cultivation system. Growth period only in line with local natural conditions, cultivation and cultivation system, to grow normally
