Water and fertilizer accurate decision-making method suitable for sunlight greenhouse and system

Abstract

The invention discloses a water and fertilizer accurate decision-making method suitable for a sunlight greenhouse and a system. The method specifically includes the following steps that S1, obtainingcrop daily water demand based on meteorological factors; S2, accumulating the obtained daily water demand to obtain an accumulated value, and obtaining the soil moisture content when the accumulated value meets a preset accumulated threshold value; S3, when the obtained soil moisture content is smaller than preset soil moisture content, irrigation amount is calculated according to the soil moisture content and the preset soil moisture content, and S4, the growth stage of crops is judged, and a model is simply, conveniently and rapidly recommended according to crop fertilization amount based ona soil nutrient balance principle. According to the water and fertilizer accurate decision-making method suitable for the sunlight greenhouse and the system, the problem that traditional water and fertilizer management of the sunlight greenhouse depends on experience decision-making is solved, and advanced artificial intelligence, the Internet of Things and a communication technology are used, sothat crop irrigation and fertilization decision-making is more scientific, efficient, timely and accurate.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a precise water and fertilizer decision-making method and system suitable for solar greenhouses. Background technique [0002] In recent years, my country's facility agriculture has developed rapidly, and the planting area has leapt to the first place in the world. However, at present, my country's facility agriculture, except for the glass multi-span greenhouses with a relatively high degree of automation, most of the facility agriculture producers mainly rely on the producers. Irrigation and fertilization are carried out by experience, and the management of water and fertilizer is relatively extensive. Excessive or insufficient irrigation and fertilization often occur, which will affect the normal growth of crops, and will also deteriorate the facility environment, resulting in the occurrence of plant diseases and insect pests and the decline in crop quality.
