淮河流域粮食产量占全国六分之一,据预测淮河2000年具有增产200亿公斤以上粮食的潜力,约相当于全国2000年计划增产量的20％以上。因此,淮河流域对我国2000年农业再上新台阶有着重大作用。目前,淮河流域粮食亩产为250公斤左右,发展较快的江苏里下河及沂沭河平原区(共有耕地3600万亩),现亩产已超过300公斤,高的已达400公斤以上。而豫东与淮北平原(共有耕地8800万亩),现亩产仅200公斤,比苏北平原亩产低100～150公斤,本流域的中低产田主要集中在这两个平原区内。经过综合治理开发,以上两个地区的粮食亩产完全有可能达到目前江
The Huaihe River Basin grain output accounts for one-sixth of the country. It is predicted that in 2000 Huaihe River will have the potential to increase the output of more than 20 billion kilograms of grain, equivalent to about 20% of the planned output increase of the whole country in 2000. Therefore, the Huaihe River Basin plays an important role in our agriculture in 2000 to a new stage. At present, grain yield per mu in the Huaihe River Basin is about 250 kilograms, and the Lixia River and Yishu River Plain (with a total of 36 million mu of cultivated land) have developed rapidly. Now the per-mu yield has exceeded 300 kilograms, and the high has reached over 400 kilograms. However, there are only 200 kg per mu in eastern Henan and Huaibei Plain (a total of 88 million mu of arable land), which is 100-150 kg lower than that of the Northern Jiangsu Plain. The middle and low yield fields of this drainage area are mainly concentrated in these two plains. After comprehensive management and development, it is quite possible that the mu production of grain in the above two areas will reach the current level
