Embodiments of the invention provide a control method and system for influence factors of fruit and vegetable growth. The method comprises the steps of obtaining a principal component with a maximum contribution rate in principal components corresponding to first indexes based on a principal component analysis method according to the first indexes of fruit and vegetable samples under all groups ofthe influence factors, and taking the principal component as a first principal component; based on a regression analysis method, obtaining a regression model according to the groups of the influencefactors and the corresponding first principal component; and obtaining the influence factors when the first principal component is maximum under the regression model, taking the influence factors as target values of the influence factors respectively, and controlling the influence factors during the fruit and vegetable growth to be the target values of the influence factors. The system comprises afeature extraction module, a principal component analysis module, a model obtaining module and a control module. The control method and system for the influence factors of the fruit and vegetable growth, provided by the embodiments of the invention, can improve the yield and / or quality of fruits and vegetables.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of agricultural production, and in particular to a method and system for regulating factors affecting the growth of fruits and vegetables. Background technique [0002] There are many factors affecting the growth and development of fruits and vegetables. The factors affecting the growth of fruits and vegetables are divided into external environmental factors and internal genetic factors. In agricultural production, external environmental factors can be regulated to improve the yield or quality of fruits and vegetables. External environmental factors include temperature, humidity, carbon dioxide concentration, light intensity, sunshine time, concentration of nitrogen and other elements, wind, concentration of various gases, weeds, microorganisms, etc. [0003] There are many factors to measure the quality or yield of fruits and vegetables. For example, because nitrate is harmful t...
