Description

Technical Field

[0001] The present invention relates to the technical field of garden management, and more specifically, to an intelligent irrigation management system and method for garden greening. Background Art

[0002] Tree transplantation has gradually become a regular task in landscaping. The transplantation of garden trees can not only quickly and efficiently solve urban landscaping and ecological problems, but also allow citizens to fully enjoy the convenience brought by urban green spaces. However, in the process of tree transplantation, it is impossible to ensure that the survival rate of trees is 100%, resulting in a waste of tree resources. Among them, cedar has a strong adaptability and can survive in poor soil conditions. It has good resistance to drought, high temperature, low temperature, and salinity.

[0003] The physiological changes of the root system of transplanted cedar can be divided into three stages: the first is the initial stage of cedar transplantation, that is, from the time of excavation to planting, the root system begins to form adventitious roots and callus tissue; the second stage is the early stage of cedar transplantation, the seedlings begin to grow new leaves and form callus tissue, but no root system is formed; the third stage is the middle and late stages of cedar transplantation, dense branches and leaves and new roots are generated. In the process of pine transplantation, the root system of cedar will be more or less damaged, resulting in water loss. At the same time, due to the damage to the root system, the water absorption capacity of the root system decreases, resulting in insufficient water supply to the tree cells. The existing technology for water supplementation is mostly through water irrigation, but it does not specifically combine the physiological changes of the cedar root system for targeted irrigation, resulting in waste of water resources and failure to meet the growth needs of cedar. In order to solve the above problems, a technical solution is now provided. Summary of the invention

[0016] Figure 1 The figure shows a flow chart of an intelligent irrigation management method for landscaping according to the present invention. Figure 1 As shown, an intelligent irrigation management method for landscaping in this embodiment includes the following steps: Step 1: obtaining cedar root system images at the initial stage of transplantation and before, during and after transplantation, as well as soil basic data and needle water content at each stage, and obtaining standard cedar root system images after transplantation, and storing and transmitting the cedar root system images, cedar root system standard images, soil basic data and needle water content; Step 2: Importing soil basic data of each period into soil moisture retention calculation formula to calculate soil moisture retention; Step 3, respectively importing the cedar root system images, soil moisture retention and needle moisture content at each period into the cedar water requirement model to calculate the cedar water requirement at each period; Step 4: Compare the water demand of cedar in each period with the water irrigation threshold of the set period. If the water demand of cedar in each period is less than the water irrigation threshold of the set period, irrigate according to the water demand of cedar; if the water demand of cedar in each period is greater than or equal to the water irrigation threshold of the set period, irrigate according to the water irrigation threshold; Step 5: Import the acquired water requirement of cedar at the initial stage of transplantation, the cedar root system image and the cedar root system standard image into the cedar root system damage degree model to calculate the cedar root system damage degree; import the water requirement of cedar before, during and after transplantation, the cedar root system damage degree, the cedar root system image and the cedar root system standard image into the cedar root system recovery degree analysis model to analyze the cedar root system recovery degree in each period; Step six, arrange the degree of recovery of the cedar roots before, during and after transplantation in ascending order. If the arrangement result is that the value of the degree of recovery of the cedar roots in the late stage of transplantation is the largest and the value of the degree of recovery of the cedar roots in the early stage of transplantation is the smallest, it indicates that the cedar transplantation is successful; if the arrangement result is not that the value of the degree of recovery of the cedar roots in the late stage of transplantation is the largest and the value of the degree of recovery of the cedar roots in the early stage of transplantation is the smallest, it indicates that the cedar transplantation is unsuccessful.

[0017] The water requirement of cedar in each period is calculated by importing the root images, soil moisture retention and needle moisture content of cedar at each period into the cedar water requirement model; the water requirement of cedar in the early stage of transplantation, cedar root images and standard images of cedar roots are imported into the cedar root damage degree model to calculate the degree of cedar root damage; the water requirement of cedar before, during and late stages of transplantation, the degree of cedar root damage, cedar root images and standard images of cedar roots are imported into the cedar root recovery degree analysis model to analyze the recovery degree of cedar roots in each period, so as to accurately evaluate the water requirement of cedar during transplantation.

[0018] In step three, the cedar root images, soil moisture retention and needle moisture content of each period are respectively imported into the cedar water requirement model to calculate the cedar water requirement of each period, specifically: the cedar root images, soil basic data and needle moisture content of the initial transplantation are imported into the cedar water requirement model to calculate the primary cedar water requirement of transplantation; the cedar root images, soil basic data and needle moisture content of the early transplantation are imported into the cedar water requirement model to calculate the first-level cedar water requirement; the cedar root images, soil basic data and needle moisture content of the middle transplantation are imported into the cedar water requirement model to calculate the second-level cedar water requirement; the cedar root images, soil basic data and needle moisture content of the late transplantation are imported into the cedar water requirement model to calculate the third-level cedar water requirement.

[0019] In step 1, basic soil data include soil moisture content, soil electrical conductivity and soil organic matter content. The soil moisture content is sampled in the transplanting area by a ring knife and placed in an aluminum box. The soil sample and the total weight of the aluminum box are weighed. , and then put it in a dryer to dry until the weight no longer changes, then take out the cooled aluminum box and the soil sample and weigh it, record it as , discard the soil sample and weigh only the aluminum box , the soil moisture content is calculated as: ; The soil conductivity is measured by weighing a 2 mm sieved air-dried soil sample and placing it in a small beaker. The soil sample weighs 50 g, and 50 ml of distilled water is added to soak the soil sample. The soil sample is stirred vigorously for 2 minutes and then allowed to stand. The conductivity is measured using a conductivity meter. The soil conductivity calculation formula is: ; Where: is the soil electrical conductivity, is the conductivity, is the temperature correction coefficient, is the electrode constant; The proportion of soil organic matter content was calculated by the potassium dichromate volumetric method. 0.5 soil sample was weighed and placed in a test tube. 5 ml of a standard solution with a concentration of 0.8 mol / L and 0.5 ml of concentrated sulfuric acid were added. The test tube was placed in an oil bath at 188 degrees Celsius and then the temperature was controlled to 175 degrees Celsius. When the bubbles in the test tube overflowed, it was boiled for 5 minutes. After cooling, it was titrated with ferrous sulfate with a concentration of 0.2 mol / L. O-phenanthroline was used as an indicator.

For example, in the early stage of transplantation, watering may need to be increased to promote root growth, while irrigation can be appropriately reduced in the later stage of transplantation to promote deep root growth and improve drought resistance; by scientifically and reasonably calculating the water requirement of cedar, we can reduce unnecessary waste of water resources, save water resources, and reduce the maintenance cost of landscaping; irrigation management based on the water requirement of cedar helps to maintain a suitable soil moisture environment, promote the growth and development of cedar roots, improve the health of plants, and enhance their resistance to stress.

[0024] In step 5, the water requirement of the cedar at the initial stage of transplantation, the cedar root system image and the cedar root system standard image are imported into the cedar root system damage degree model to calculate the cedar root system damage degree.

The number of pixels of the root system.

[0025] By calculating the degree of root damage of cedar, the health status of cedar roots in the early stage of transplantation can be timely evaluated, the degree of root damage can be discovered and quantitatively evaluated, which is helpful to take appropriate measures for repair and management; the cedar root damage degree model can calculate the degree of root damage according to the number of pixels in the cedar root system image, and quantify the degree of root damage into a specific value, which is helpful to understand the health status of the root system more accurately; accurate assessment of the degree of root damage can help garden managers to carry out management and repair work more targeted, which helps to improve management efficiency and root recovery speed.

[0026] In step 5, the water demand of cedar before, during and after transplantation, the degree of damage to the cedar root system, the cedar root system image and the cedar root system standard image are imported into the cedar root system recovery degree analysis model to analyze the degree of recovery of the cedar root system in each period.

[0027] Combining the cedar's water demand, root damage level and root image data, we can more comprehensively evaluate the recovery of the cedar root system. By quantitatively analyzing the degree of root recovery, we can promptly detect poor root recovery or abnormalities, which will help to take appropriate management measures for adjustment and improvement.
