Tomato real-time weight measurement system and plant growth model calculation method thereof

Abstract

The invention discloses a tomato real-time weight measurement system and a plant growth model calculation method thereof. A data acquisition device is connected with a crane scale, the data acquisition device and the crane scale are both connected with a power module, the power module supplies power to the crane scale and the data acquisition device, a data transmission module is further connected to the data acquisition module, and an upper computer is connected to the data transmission module; the daily simulation irrigation amount MDI is obtained through calculation according to the daily real-time growth amount delta MTG of plants and the daily light temperature coupling amount DLT of a sunlight greenhouse. The crane scale is adopted to measure the real-time weights of parts over the ground of stems, leaves, fruits and the like of the tomato plants in real time, then the daily growth amount of the plants is simulated and calculated, and finally the daily irrigation amount is calculated through the combination of sunlight greenhouse indoor environment conditions. The model is not only good in application effect, wide in application range and suitable for soil cultivation and bagged soilless cultivation, but also can be used for calculation of other sunlight greenhouses or facility fruit vegetable type vegetable crop growth models and irrigation models.

Description

technical field [0001] The invention relates to the field of facility agriculture planting, in particular to a tomato real-time weight measurement system in a solar greenhouse and a plant growth model calculation method thereof. Background technique [0002] Establishing a greenhouse crop growth model is the basis for realizing precise and automated management of the greenhouse environment and crop growth. At present, developed countries have established greenhouse environment control models and growth models of many horticultural crops under the conditions of large-scale intelligent multi-span greenhouses. Since the smart greenhouse realizes the precise control of the environmental conditions of the greenhouse such as light, temperature, water, gas, and fertilizer, so that the crops are in the best or suitable growth environment conditions, the actual application effect of the crop growth model is better. However, the main type of facility in my country is the solar greenh...

Problems solved by technology

However, the main type of facility in my country is the solar greenhouse. Due to the simple structure of the solar greenhouse, imperfect supporting equipment, poor environmental control capabilities, and huge changes in environmental factors such as light and temperature, the simulation results of foreign greenhouse crop growth models have large deviations and are difficult to apply.

For this reason, the inventor developed a method based on platform scales to measure the real-time weight of plants: a method for simulating and calculating the amount of irrigation water for substrate bag cultured crops in a solar greenhouse (application number: 201610414523.X), which better solves the problem of severe environmental changes in the solar greenhouse The problem of inaccurate simulation of traditional tomato growth model caused by

However, this invention uses a desktop electronic scale, which can weigh all the substrate, root system, stems, leaves, and fruits of bag-cultured tomatoes, but it can only be applied to the cultivation method of tomato substrate-bag cultivation, and the scope of application is limited. , cannot be applied to the soil and trough substrate cultivation of tomatoes in large-scale solar greenhouses
