The invention discloses a method for realizing high-quality rice production by arranging a sowing period according to the daily average temperature. The rice quality difference of different rice varieties at different environment temperatures is ascertained, the response of quality indexes of the specific variety in a filling period to the daily average temperature is understood, the optimal temperature of the specific variety is calculated according to a response curve to determine the full heading period of the rice variety, and the sowing period is deduced according to the full heading period. According to the method, the reasonable sowing period can be determined according to temperature and light responses of different varieties, so that the temperature of the rice filling period is within the temperature range most suitable for rice quality formation, and the rice quality of the varieties can be remarkably improved; the rice sowing period can be more accurately determined according to the appropriate daily average temperature required for the rice variety to form the high-quality rice in the filling period and the response curve of the variety in the full heading period and the sowing period; and the method is applied to production of the high-quality rice in different geographical environments according to the rice sowing period.
Description
technical field [0001] The invention relates to the technical field of agricultural technology, in particular to a method for arranging sowing dates according to daily average temperature to realize high-quality rice production. Background technique [0002] In addition to being controlled by genetic factors, the quality of rice is also affected by environmental factors. For example, the quality of early indica rice is largely determined by the climatic conditions at the filling stage. Studies have shown that planting indica rice varieties in the late rice season instead of the traditional growth period can significantly improve rice quality; the high temperature in the early stage of rice grain filling can significantly accelerate the grain filling speed, and correspondingly shorten the grain filling time, resulting in loose starch grains and a decrease in grain weight and polished rice rate. Increased chalkiness. Climate change, characterized by an increase in average dai...
