The embodiments of the present invention provide a precise decision-making method and system for a tidal seedling nutrient solution. The irrigation decision-making mode based on the cumulative value of daily solar radiation and the control of the solar radiation value in stages is more in line with the demand law of seedlings for water and nutrients, and avoids irrigation in rainy days. Reduce the occurrence of pests and diseases; based on environmental factors, seedling growth models of different crops, and water and fertilizer demand models, the seedlings of different crops can obtain the best water and fertilizer requirements at different growth stages, which is of great practical significance for the production of high-quality and strong seedlings and the protection of the ecological environment. ;It can effectively realize the automation and precision of tidal seedling nutrient solution management, reduce the cost of comprehensive production management, reduce pests and diseases, improve labor efficiency, and fully improve the efficiency and efficiency of facility seedling breeding, which can not only ensure the production of high-quality and strong seedlings, but also avoid water and Fertilizer waste, improve water and fertilizer utilization efficiency.
Description
technical field [0001] The invention relates to the technical field of agricultural facilities, in particular to a method and system for precise decision-making of a tidal seedling nutrient solution. Background technique [0002] Tidal seedling cultivation is a new method of irrigating seedlings. Its main advantages are high efficiency, water saving and environmental protection. A lot of research has been done in many developed countries in Europe and the United States. The nutrient solution management of tidal irrigation systems used in production by developed countries in foreign facilities agriculture represented by the Netherlands has basically achieved automatic regulation, with advanced equipment and leading technology. Our country should learn from the advanced experience of foreign countries and carry out the research and development of tidal irrigation technology and key equipment based on our national conditions, comprehensively improve the technological content o...
