从丰产栽培上的良种良法,到育种上要在生态类型基础上明确育种目标及选择方向,都说明了对品种生态类型研究的重要性。本试验通过对一批推广的良种在四个生态条件下的栽培表现,想要明确: (1)不同生态条件下,大豆品种的产量变化,用以说明品种和生态环境的关系; (2)不同生态条件与大豆产量性状关系,用以说明哪些产量性状易受生态条件影响,并明确不同生态条件下适合的高产品种生态类型。
From the cultivation of good varieties of good law, to breeding on the basis of the ecological type of breeding objectives and clear direction of the choice, all shows the importance of the study on the type of ecological species. In this experiment, through the cultivation performance of a batch of popularized seed varieties under four ecological conditions, we want to make clear: (1) the yield changes of soybean varieties under different ecological conditions to illustrate the relationship between varieties and ecological environment; (2) Different ecological conditions and soybean yield traits, to explain which yield traits are susceptible to ecological conditions, and clear different ecological conditions suitable for high yield varieties ecological type.
