STUDIES ON THE POTENTIAL OF GRAIN PRODUCTION IN THE NORTHEAST REGION OF CHINA

  • Publish Date: 1993-03-20
  • Northeast region covers an area of 1.24 million km, making up 12.9% of the total area of China, with a population of 103 million, 9.9% of the total population of China. The grain commodity rate is over 35%. It is one of the very important regions of grain production in China. As population and grain demand unceasingly increase, the potential of grain production, and the commodity grain provided for the nation are the major problems about grain consumption and distribution in the future. And they directly affect the realization of national planning objective of grain production.The analysis of grain production conditions and history indicates that: 1) The increase of total grain output is mainly dependent on the increase of grain yield per unit area, but not the enlargement of grain sown area. 2) The factor to affect grain yield per unit area are materials input, correct policies, yearly climatic variation. 3) By the year 2000 and 2010 the total grain output in this region will be respectively 66.16-66.29 and 71.68-72.89 million tons. 4) According to the results of research, the potential of increasing grain output in Heilongjiang and Jilin provinces is the greatest in the future.The key measures to raise grain yield include increasing material and energy input, strengthening the base construction of farmland, emphasizing the increasing of yield per unit area of medium and low yield fields, and controlling the amount of farmland which are taken up by any other activities.

STUDIES ON THE POTENTIAL OF GRAIN PRODUCTION IN THE NORTHEAST REGION OF CHINA

Abstract: Northeast region covers an area of 1.24 million km, making up 12.9% of the total area of China, with a population of 103 million, 9.9% of the total population of China. The grain commodity rate is over 35%. It is one of the very important regions of grain production in China. As population and grain demand unceasingly increase, the potential of grain production, and the commodity grain provided for the nation are the major problems about grain consumption and distribution in the future. And they directly affect the realization of national planning objective of grain production.The analysis of grain production conditions and history indicates that: 1) The increase of total grain output is mainly dependent on the increase of grain yield per unit area, but not the enlargement of grain sown area. 2) The factor to affect grain yield per unit area are materials input, correct policies, yearly climatic variation. 3) By the year 2000 and 2010 the total grain output in this region will be respectively 66.16-66.29 and 71.68-72.89 million tons. 4) According to the results of research, the potential of increasing grain output in Heilongjiang and Jilin provinces is the greatest in the future.The key measures to raise grain yield include increasing material and energy input, strengthening the base construction of farmland, emphasizing the increasing of yield per unit area of medium and low yield fields, and controlling the amount of farmland which are taken up by any other activities.
