| Notes | The increasing trend and its causes of grain yield are the basis for a nation to formulate the macroscopic agriculture policies and measures. Increasing Production Theory of Scientific and Technological Progress（IPTSTP）is defined as follows： climate is undulating, while the technological progress is sustainable and it is the main driving force of sustainable increasing production for many years. Increasing Production Forecasting Model of Scientific and Technological Progress（IPFMSTP）is a regression equation for the moving average data of the per unit area yield. The IPTSTP and its methods were applied to analyze the grain yield potential in China and northeast China, respectively. The results showed that Liaoning Province was the earliest one which accelerated per unit area yield by scientific and technological progress, and the latest one was Heilongjiang Province. Compared with other provinces at present, the contribution rate of the scientific and technologi-cal progress in Heilongjiang province was lower |
