Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of soilless culture environment monitoring equipment, in particular to a soilless culture substrate liquid discharge amount monitoring device. BACKGROUND

[0002] The substrate is defined differently in different disciplines.

[0003] In chemistry, the substrate refers to all components in the sample except the analyte; in industry, the substrate refers to a continuous medium with intermittent particles dispersed therein; in biology, the substrate refers to an amorphous gelatinous substance composed of biological macromolecules, colorless and transparent, with certain viscosity and interstitial fluid in the pores.

[0004] Currently, there is no self-developed soilless culture substrate environment and liquid discharge amount real-time monitoring device related product. Compared with similar technical products, the present device also has certain differences. The sales of similar hardware devices are only used in conjunction with their own software systems, which has certain barriers,

[0005] Secondly, the price is expensive. It is difficult for small and medium-sized agricultural parks and individual growers to afford.

[0006] Thirdly, similar products are integrated devices, and each hardware uses a separate device. There is a problem of long after-sales maintenance cycle.

[0007] Finally, there are differences in technical principles. Similar products measure the overall weight of the plant substrate bag and the liquid discharge amount, but do not monitor the temperature, humidity and other parameters of the upper and lower layers of the substrate bag. We do not collect the overall weight of the substrate bag, but directly monitor the substrate environment parameters and liquid discharge amount.

[0008] Abundant roots and lush leaves are the basis for ensuring high yield and high quality of crops. However, roots grow in dark environments such as soil and substrate, which is very difficult for the naked eye to monitor in real time. Monitoring by pulling out the roots will also cause mechanical damage, resulting in decreased plant survival rate and reduced yield. Therefore, it is necessary to ensure the health of the roots and monitor the state of the living plant roots in real time. According to the technical barriers, high cost, and optimization of measurement indicators of similar products, a root environment and liquid discharge parameter real-time monitoring device for substrate soilless culture is developed. SUMMARY

[0009] In view of the problems mentioned in the background art, the present application aims to provide a soilless culture substrate liquid discharge amount monitoring device to solve the problems mentioned in the background art.

[0010] The above technical purpose of the present application is achieved by the following technical scheme:

A plurality of limiting rods 27 are fixedly connected to the bottom of the filter screen plate 13.

The plurality of limiting rods 27 fixedly connected to the bottom of the filter screen plate 13 can make the filter screen plate 13 keep a certain distance from the bottom of the substrate bag 1, which can improve the drainage effect of the substrate.

[0043] ReferenceFigure 1 、 Figure 2 、 Figure 3 and Figure 4 The distance between the filter screen plate 13 and the bottom of the substrate bag 1 is 3 cm, the filter screen plate 13 is a stainless steel mesh filter screen plate, and the distance between the filter screen plate 13 and the bottom of the substrate bag 1 can reduce the possibility of root growth extending to the drainage hole 9 and reduce the possibility of root contact with the collection chute 4.

[0047] Principle and advantages: When in use, according to the different installation of substrate environment parameters and liquid discharge monitoring devices for different crop cultivation modes, if it is ground cultivation, the substrate bag 1 or substrate groove can be raised by 40-50 cm according to the needs, and the first lead wire 16 and the second lead wire 17 of the temperature sensor 15 and the fifth lead wire 23 and the sixth lead wire 24 of the humidity sensor 22 are inserted at 5 cm below the top and 5 cm above the bottom of the substrate bag 1 respectively, for monitoring the real-time changes of temperature and humidity of the substrate surface and bottom layer at different time periods after irrigation. Then the third lead wire 19 of the conductivity sensor 18 and the fourth lead wire 21 of the pH sensor 20 are inserted at 5-10 cm above the bottom, so as to determine the changes of temperature, humidity, pH and conductivity of different grooves and different substrates under different climates.

If it is a high cultivation mode, the substrate groove does not need to be raised, and the sensors can be directly inserted into the groove through the side wall.

[0048] Through the setting of the filter screen plate 13 and the air inlet pipe 10, and setting a certain distance between the filter screen plate 13 and the bottom of the substrate bag 1, the air inside the substrate bag 1 can be circulated, which can ensure the healthy growth of the oxygen demand of the root system, improve the drainage effect of the drainage, reduce the possibility of root growth extending to the drainage hole 9, and reduce the possibility of root contact with the collection channel 4. Through the drainage hole 9 opened at the bottom of the substrate bag 1, the substrate drainage inside the substrate bag 1 can be discharged, the drainage can be guided by relying on the collection channel 4, the drainage can be collected by relying on the liquid collecting barrel 7, the collected substrate drainage can be weighed by relying on the electronic scale 601, and then the weighed data can be transmitted by the communication transmission sensor 602 and transmitted to the data software platform. With the gradual increase of irrigation amount every day, the substrate drainage amount increases from nothing to more. The substrate exudate will enter the drainage collection barrel through the reserved special flow channel. At this time, the substrate scale running 24 hours will weigh the weight change in time and transmit it to the software data platform synchronously. Thus, we can master the data of the first drainage time and the total drainage amount. Combined with the irrigation amount data, the drainage ratio can be calculated, which is an important indicator for judging whether the irrigation is reasonable.

[0049] Based on the above data, by optimizing the existing irrigation mode under different conditions of different crops, a more accurate irrigation model is formed, which can guide more precise irrigation of crops, promote water and fertilizer saving of crops, and improve quality and efficiency.
