摘要
根据粮食作物比较优势分析,我国小麦、玉米优势产业带为东北地区、黄淮海平原、河套平原、汾渭平原、河西走廊和新疆一线;稻谷优势产业带为长江中下游区(含浙闽、两广等部分地区)一线;大豆优势产业带为东北地区一线。优势产业带的资源优势是光照充足、雨热同季、昼夜温差大。黄淮海平原2000年小麦玉米单产为其光温生产潜力的28.5%,提高单产尚有较大的潜力。
According to the analysis on comparative priority of grain crops, the priority industrial belt for wheat maize in China is located in north——eastern region, Huang, Huai, Hai River Plain, Hetao Plain, Fenwei Plain, Hexi Corridor and Xinjiang; the priority industrial belt for rice is located at middle lower valley of the Yangtze River （including Zhejiang, Fujian part of Guangdong and Guangxi; the priority industrial belt for soybean is also located at northeast region. The resources priorities of the priority industrial belts are. daylight is abundant, raining season is the same as hot season, and temperature differences between day night are great. In 2000, the yield per unit of area in Huang, Huai, Hai River Plain only takes 28.5 of its light temperature production potential. There is great potential in raising yield per unit of area.
