多年生香豌豆在黄土高原地区引种适宜性评价

多年生香豌豆从美国引种后在黄土高原大部分地区的适应性较强。结合气候相似法、模糊综合评判法以及引种栽培试验,得出多年生香豌豆的适生中心区位于气温适中的黄土高原中部呈西南～东北走向的一个狭长地带,主要包括黄土高原沟壑区、丘陵沟壑区二副区、三副区以及太行山西部山地类型。

Evaluation of the adaptability of Lathyrus latifolius from USA to the Loess Plateau

In most parts of the Loess Plateau, the adaptability of Lathyrus latifolius from USA is quite strong. By combining the use of the climate similarity method, comprehensive fuzzy evaluation, as well as carrying out introduced plant experimentation, the most suitable area for L. latifolius was determined. The area is located in the middle of the Loess Plateau, in a narrow strip going from the southwest to the northeast, which has mild temperature. This area mainly includes the tableland and gully region, sub-region 2 and 3 of the hill and gully region, and some mountainous area of the west Taihang Mountains.
