Abstract
According to the principle of agricultural systemic engineering, the production potential and technical renew for late season rice growth through the tossing along low Yangtze River region were studied with the method of regress and mathematic model of rice yield was set up. The result indicated the rice yield potential was 9303.75kg/hm2 in the area and the integrated agronomic characters for rice yield of 9303.75kg/hm2 were as follows: 2.3-2.6 million seedling per hm2, 233.55-268.95kg pure nitrogen fertilizer per hm2, among which 9.64%~15.12% was used in heading stage. In the model, the order of factors affecting rice yield was basic seedling number > the rate of nitrogen fertilizer in heading stage to total nitrogen > total N-fertilizer.关键词
