| 宁夏为一年一熟制地区，为提高冬闲田的复种指数，合理利用光热资源，发挥其生态效益和经济效益，需做好冬牧70的推广。为此，需搞清楚什么茬口种，什么地方适合种？为回答这两个问题，文章利用14个气象观测站1981～2010年的气象观测数据，首先，根据文献反查和大田试验数据反推气候适宜性区划指标，再结合坡度、海拔和土地利用类型等信息，构建冬牧70总的适宜种植区划指标，然后利用ArcGIS平台，获得不同复种模式下冬牧70的适宜种植区划结果。根据区划结果可知：玉米—冬牧70—插秧稻复种模式最适宜推广，大部分地区可保障齐穗期收割的需求。其次是水稻—冬牧70—插秧稻复种模式，大部分地区可保障抽穗期收割的需求。而玉米—冬牧70—玉米或旱直播稻复种模式仅能保障孕穗期收割，水稻-冬牧70—玉米或旱直播稻复种模式仅能保障拔节期至孕穗期收割。通过该文的研究为指导冬牧70在宁夏灌区的大范围推广提供了技术支撑，也为其他复种作物的大面积推广提供了参考。 |

| Abstract: |
| Ningxia belongs to a single cropping system region.It is essential to popularize Wintergrazer-70 in order to improve the fallow cropping index，use reasonably the light and heat resources，and obtain ecological and economic benefits.Based on 14 meteorological stations observation data from 1981 to 2010，this paper firstly established climate suitable regionalization index using the literature reverse lookup and field test methods.And then，it constructed the total suitable planting regionalization indexes of the wintergrazer-70 by combined with slope，elevation and land use type and other information.Finally，it analyzed the suitable painting regionalization results under the different cropping patterns by used the ArcGIS platform.The results showed that the multiple cropping pattern of the corn-wintergrazer-70-transplanting rice was the best pattern，and can be harvested at the full heading stage.The rice-wintergrazer-70-transplanting rice was the better pattern and could be harvested in the heading stage.While，the multiple cropping pattern of the corn-wintergrazing-70-corn（or dry direct seeding rice）and the rice-wintergrazing-70-corn（or dry direct seeding rice）were the worse patterns which could be harvested in the booting stage or in the stage from jointing to booting stageThis paper could provide the technical support to guide the wide extension of the wintergrazing-70 in the Ningxia irrigation area. |
