GS洛旱2号适宜生态类型区灰色布局分析

为了确定GS洛旱2号适宜推广种植区域,采用作物品种灰色布局原理与方法,对其在黄淮冬麦区的适宜生态类型区进行了研究,为大面积推广提供科学依据,并分析了品种灰色布局原理与方法的可行性。结果表明,洛旱2号适宜推广种植的区域为以宾州、长武、鹤壁、临沂、洛阳、嵩县、渭南、郑州为代表的生态类型区。作物品种灰色布局原理与方法改善了传统品种布局仅考虑产量因素的局限性,在指导大区域品种布局时更宜适用。

Study of the ecological zones suitable for GS Luohan 2 to grow

In order to demarcate the area suitable for GS Luohan 2 to grow, the principles and methods of the gray arrangement for crop cultivars were used to study the ecological types of the Huang Huai winter wheat zone to which GS Luohan 2 could adapt well so as to provide the basis of the large-scale extension of the cultivar. Meantime, the feasibility of the principles and methods of the gray arrangement for crop cultivars was discussed. The results showed that the regions suitable for the extension of GS Luohan 2 were the places represented by Binzhou county, Changwu county, Hebi county, Linyi county Luoyang city, Songxian county, Weinan city and Zhengzhou city. By the way, the principles and methods of the gray arrangement for crop cultivars reduced the limitation of the traditional crop arrangement which took only crop yields into account and thus could play a guiding role in the arrangement of crop varieties.
