| 摘 要： | 本文分析了重庆秋玉米栽培与气象条件关系和主要气候问题,指出秋季热量资源是影响秋玉米分布的主要原因,将秋玉米生育期间80%保证率≥16℃活动积温作为重庆市秋玉米气候区划指标。利用ARCGIS和数字高程模型(DEM)得到了重庆市秋玉米生育期间80%保证率≥16℃活动积温的空间分布,以此为基础将重庆市秋玉米栽培区划分为:热量丰富中熟秋玉米适宜栽培区,热量较丰中熟鲜食秋玉米适宜栽培区、热量一般早熟秋玉米适宜栽培区、热量较差早熟鲜食秋玉米适宜栽培区以及热量不足秋玉米不适宜栽培区等5种类型区,并提出了相应的措施建议。

| Abstract: | This paper analyzes the relationship between the cultivation and meteorological conditions of autumn corn in Chongqing and the main climatic issues autumn corn faces.It points out that heat is the main factor affecting the distribution of autumn corn.This paper also used the 80% guaranteed rate of corn growth and ≥ 16℃ activity accumulated temperature as the metrics of Chongqing autumn corn and ARCGIS and Digital Elevation Model (DEM) to calculate the spatial distribution of 80% guaranteed rate ≥ 16℃ activity accumulated temperature results during the growth period of autumn corn.In conclusion,the cultivation area of autumn corn in Chongqing is divided into:the abundant-heat area suitable for medium-maturity corn;the area with relatively abundant heat suitable for the cultivation of mid-ripe fresh edible autumn corn;the area with fair heat suitable for early autumn corn;the area with poor heat suitable for precocious fresh edible autumn corn;and the area which is lack of heat and not suitable for the cultivation of autumn corn.This paper also gives the corresponding countermeasures and suggestions for issues mentioned above. |
