Problems solved by technology
Due to the small capacity of the substrate bag cultivation, it is necessary to take a small amount of frequent fertilizer and water management measures. Therefore, the bag culture crops in the solar greenhouse need to realize the timing, quantitative and positioning supply of fertilizer and water according to the growth of the crops. The existing technology adopts the method of crop growth model Calculating the growth of crops cannot truthfully reflect the actual growth of crops for irrigation needs, and at the same time, it is impossible to achieve irrigation based on the light-temperature coupling relationship between the real-time light and temperature of the solar greenhouse environment, and it is impossible to achieve precise irrigation and better results. Meet the growth needs of solar greenhouse crops such as crops

Embodiment Construction
[0009] The invention calculates the daily simulated irrigation amount MDI of the crops based on the growth model of the real-time growth amount of bag cultured crops in the solar greenhouse and the sum of the light-temperature coupling amount every hour in 24 hours a day. Include the following steps:
[0010] 1. Calculation and verification of crop growth model based on real-time growth
[0011] 1. Simulated measurement of plant daily real-time growth △MTG
[0012] Put the cultivation bags for planting crop plants in a tray and put them on an electronic scale with an accuracy of 0.01kg for real-time weighing every ten minutes, and automatically record the growth amount through wireless sensors. According to the records and observations, the weight of the plants in the early morning of each day no longer changes greatly, so the weight measurements in the early morning of the 9th day after planting are used to calculate the daily real-time growth of the plants △MTG. Since the ...

The invention relates to a method for simulating and calculating the amount of irrigation water for the growth of substrate bag cultured crops in a solar greenhouse. According to the relationship between the daily real-time growth of bag cultured crop plants and the coupling amount of light and temperature in the solar greenhouse, a solar greenhouse substrate bag culture method is established. A simulation model for daily moisture-accurate irrigation of crop growth. Comparing the daily simulated irrigation amount MDI of crop plants with the actual daily measured irrigation amount RDI of crop plants during normal growth for model verification, the fitting degree between the two can reach 82.34%, the simulation accuracy of the model is high, and the application effect is good , with good feasibility. The simulated calculation method can be used to manage the amount of irrigation water for tomato and other substrate bag cultured crops in the solar greenhouse, and adjust the irrigation water amount according to the growth status of the crops and the environmental conditions in the solar greenhouse, so that the irrigation amount can better meet the growth needs of the crops.
Description
technical field [0001] The invention relates to the technical field of modern agricultural irrigation, in particular to a method for simulating and calculating the amount of irrigation water for bag cultured crops in a solar greenhouse. Background technique [0002] An important development trend of modern crop production in greenhouses is to establish crop models, which can describe the relationship between crop growth changes and environmental conditions, such as light intensity, temperature, humidity, etc. The protected horticultural crop model is the core part of the intelligent operation and management software of greenhouse production, which plays an important role in the regulation of crop growth environment parameters in the facility and the high-quality and efficient production function of facility agriculture. [0003] At present, the environment control model and the growth model and irrigation model of many horticultural crops under the condition of large-scale i...
