摘要: 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。

Abstract: he main production area of Chinese millet (accounting for 97%of the total sowing area)was divided into 5 districts(namely,spring millet with very early-maturing, early-maturing, mid-maturing, late- maturing and summer millet districts) and 11 subdistricts in accordance with the national standards of maturity periods for millet varieties,the light-temperature ecological types for millet varieties and the load values of the comprehensive effect factors of 14 adaptability-related ecological factors in 160 test sites. The ecological characters and the" characters of the varieties were analysed and the existent problems were pointed out for each district. The division was characterised by:l. The use of climatic and geographic factors, millet ecological characters, especially, uniform mature period standards, so as to link up the areas under the same ecological conditions regardless of the administrative region; 2 .Theinitial invention of the national division, for grain crops, characterised by a multitude of test sites and factors, the load values of the comprehensive effect factors,and high typicality; 3. The solution of the problems of ambiguity in the division of some main millei. production area, such as Chengcle, Chaoyang, Chifeng, Tieling, and Jinzhou.
