The invention provides a method and system for determining the meteorological yield of sesame seeds. According to the method and the system, current-year sesame meteorological index information is predicted through a meteorological index prediction model according to main meteorological index information, which influences crop growth and mainly includes historical data and data of current-year known time, of the crop growing region; the meteorological biomass of the sesame in each growth period in the current year is predicted through a meteorological index-meteorological biomass prediction model, and the current-year sesame meteorological yield is predicted through a meteorological biomass- meteorological yield prediction model. According to the method and system for determining the meteorological yield of the sesame seeds, by establishing the meteorological index-meteorological biomass prediction model of sesame seeds in each growth period, meteorological biomass prediction of sesamein each growth period can be realized, so that the sesame meteorological yield prediction accuracy is improved, the sesame meteorological yield is dynamically published, and technical support is provided for guaranteeing supply and demand balance of the sesame market in China.
Description
technical field [0001] The invention relates to the field of economic crop yield prediction, and more particularly, relates to a method and system for determining the meteorological yield of sesame. Background technique [0002] Sesame yield is usually divided into biological yield and economic yield. Biomass, referred to as biomass, refers to the total amount of various organic substances produced and accumulated by sesame in each growth cycle through photosynthesis and absorption, that is, through the transformation of matter and energy. The root system is usually not included in the calculation of biomass. Economic yield refers to the amount of harvested sesame seeds required for cultivation purposes, which is generally referred to as yield. Usually, the level of economic output is directly proportional to the level of biomass. [0003] The length of the growth period of sesame is not only mainly determined by the heredity of sesame, but also due to factors such as clim...
