Quality control method for greenhouse flowers

Abstract

The invention discloses a quality control method for greenhouse flowers. The method comprises the following steps: choosing one flower irrigation area with better growth condition in the specific growth phase as a standard irrigation area, and using a nitrogen-potassium measurement microelectrode to measure and fit out concentration distribution curves of nitrate ions, ammonium ions and potassium ions as standard curves; adopting the same measurement method for irrigation areas to be controlled in corresponding growth phases to obtain average concentrations of the nitrate ions, the ammonium ions and the potassium ions of flowers at present irrigation areas in corresponding growth phases; and obtaining profit-loss conditions of corresponding ion concentrations in the irrigation areas to be controlled and fertilizer application control policies according to difference values between the concentrations of the nitrate ions, the ammonium ions and the potassium ions in the irrigation areas to be controlled and the standard concentrations of the nitrate ions, the ammonium ions and the potassium ions, so that the quality of the flowers is controlled.

Description

technical field [0001] The invention belongs to the technical field of greenhouse manufacturing, and in particular relates to a method for controlling the quality of greenhouse flowers based on an ion-selective microelectrode, which controls the quality of greenhouse flowers. Background technique [0002] People's living standards and consumption levels are constantly improving, requiring a beautiful living and home environment, which has led to the rapid development of the horticultural industry. Among them, the output of greenhouse flowers accounts for a larger proportion of the total output of flowers in the horticultural industry. In the flower market, the prices of different varieties of flowers are different, and the prices of the same variety of flowers are also different, mainly depending on the quality, and the quality of flowers is related to the environment during the entire flower cultivation process, such as light, water, fertilizer, temperature, etc. , where fe...

Problems solved by technology

[0003] Traditional greenhouse flower quality control is based on the experience of agronomists, so there are subjectivity and individual differences in diagnosis, which may easily cause excess or shortage of nutrients in plants during the fertilization process, causing irreversible damage to crops; the new greenhouse crop quality The control method mainly uses image detection technology, multi-sensor technology, spectrum and hyperspectral technology to detect crops, which makes up for the shortcomings of manual diagnosis, such as a crop based on canopy reflection spectrum disclosed in Chinese Patent No. 200710019340.9 Non-destructive detection device for leaf nitrogen nutrition index; Chinese patent No. 20091015405.4 discloses a tea quality control method based on characteristic spectrum, etc.

Since crop growth is a dynamic process, the above-mentioned disclosed technical solutions are difficult to grasp the current real nutritional status of crops quickly and in real time due to reasons such as poor real-time performance or inability to perform live detection, resulting in lagging water and fertilizer control and affecting quality. control
