以160个代表点的14个与谷子适应性有关的生态因子综合效应因子荷载值、全国谷子生态联合试验所确定的谷子品种光温生态类型以及谷子品种全国统一熟期分类三者结合划区。将中国谷子主产区(占全国谷子播种面积的97％)划分为春播特早熟区、早熟区,中熟区、晚熟区和夏谷区等5个生态区11个亚区。分区分析了生态特点和品种特性,指出存在的问题。本区划具有以下特点:(1)以气候地理因子与谷子生态特性,特别是按谷子统一熟期分类结合划区,使相同生态条件地区连片,突破了大行政区的框架;(2)代表地点和因子多,且又通过运算综合成因子荷载值划区,代表性大;(3)解决了过去划区中承德、朝阳、赤峰、铁岭、锦州等重要产谷区归属模糊的问题。
Fourteen cross-pollination factors of ecological factors related to millet adaptability at 160 representative points, the light and light ecotypes of millet varieties and the national uniform maturity classification of millet varieties determined by the National Millet Ecology Experiment. The main producing areas of China’s millet (accounting for 97% of the country’s cereal area) are divided into 11 sub-areas of 5 ecotopes, including spring early maturity precocity, precocity, midrib, late maturity and summer valley. Zoning analysis of ecological characteristics and variety characteristics, pointed out that the existing problems. The zoning has the following characteristics: (1) The combination of climatic and geographical factors and millet ecological characteristics, especially according to the same maturity classification combined with the division of the same ecological conditions area, breaking the framework of the large administrative regions; (2) on behalf of the location (3) It solves the problem of fuzzy assignment of the important valley including Chengde, Chaoyang, Chifeng, Tieling and Jinzhou in the past delineation area.
