Description

Soil moisture monitoring feedback device

Technical Field

The utility model belongs to the technical field of afforestation, especially, relate to a soil aqueous vapor monitoring feedback device.

Background

The root soil environment created during landscaping construction is important for the survival of nursery stocks. Usually, when trees and shrubs are newly planted or transplanted, PVC (polyvinyl chloride) vent pipes are laid in the holes in a three-dimensional mode, the moisture characteristics of soil can be improved to a certain extent, but the moisture characteristics of deep roots are difficult to judge in the future, and whether water is accumulated at the bottoms of the planting holes or not can not be effectively judged after rainfall. The traditional method for judging whether the roots are accumulated with water after rain mainly comprises the steps of observing the water accumulated on the ground and the growth state of branches and leaves of seedlings. The surface soil is loose, rainfall is easy to seep, but no water is accumulated on the ground, whether water is accumulated in the tree pit or not can not be effectively reflected, and measures are usually lagged after branches and leaves grow abnormally, and at the moment, the growth state of the nursery stock is influenced, even the survival of the nursery stock is influenced.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments;

as shown in fig. 1, the utility model discloses a soil moisture monitoring and feedback device, which comprises a main body cavity 1, wherein a liquid inlet 11 and a liquid outlet 12 are arranged above the main body cavity 1, and a funnel 2 is inserted into the main body cavity through the liquid inlet and is used for making moisture in soil permeate into the main body cavity 1; hose 3 one end is inserted main part chamber bottom through the liquid outlet, and the main part chamber is stretched out to the other end, makes things convenient for hydroenergy to be taken out smoothly from hose 3. Hose 3 polyethylene plastic material, hose 3 overcoat one deck ordinary plastic tubing is done the protective layer again when using, can increase hose 3's corrosion resistance, prevents that hose 3 from damaging. The contact position of the liquid inlet 11 and the funnel, the contact position of the liquid outlet 12 and the hose 3 are sealed by the sealant 4, so that the whole main body cavity 1 is ensured to be complete in air tightness, and the water inside the main body cavity 1 is protected from pollution. The inner surface of funnel 2 is equipped with filter screen 21, be equipped with filter layer 211 on the filter screen 21. By arranging the filter net 21 and the filter layer 211 in the funnel 2, the sludge in the soil can be prevented from entering the main body chamber 1, and the water in the main body chamber 1 can be prevented from becoming turbid.

As shown in fig. 2, the gabion mesh 5 is a steel wire gabion mesh, and plays a role in fixing the device, preventing the upper layer from being inclined and damaging the device during soil covering, and when the root depth of a seedling is buried in soil, the outer layer gabion mesh 5 of the device can effectively protect the device. When the buried soil is less than 30cm, the protective stone cage net 5 can be directly used without being added. The device is particularly suitable for planting the nursery stocks which have high requirements on soil ventilation and water conservancy and are high in price, and can detect the ponding condition of the roots of the nursery stocks in time so as to take corresponding measures in time, protect the healthy growth of the nursery stocks and improve the survival rate of the nursery stocks.

In specific implementation, the device preferably adopts the whole structure with the width: 100mm, length: 100mm, height: 300mm and the load-bearing capacity of 50kg-100 kg. Materials used and their specifications: firstly, a wide-mouth thickened PE plastic bottle with the volume of 500ml and the thickness of 3 mm; a PE plastic funnel 2 with the caliber of 60 mm; a PE plastic hose 3 with the pipe diameter of 2 mm; the sealant 4 adopts glass cement; fifthly, a nylon filter screen is 21-200 meshes, and a piece of white qualitative filter paper is used by folding and pasting the filter screen 12.5cm multiplied by 12.5 cm; sixthly, quartz sand or sand; seventhly, the specification of the steel bar gabion is 100mm multiplied by 130 mm. During the specific manufacturing, a 500ml wide-mouth plastic bottle (the volume of the bottle can be adjusted according to the actual situation) is selected, a hole is drilled at the geometric center of each bottle cap to form the liquid inlet 11, the diameter of the hole is determined according to the neck of the funnel 2, and the plastic bottle is preferably close to the projection plane of the selected funnel 2. A small hole is drilled at the edge of the bottle cap to form a liquid outlet 12, a polyethylene plastic hose 3 penetrates into the small hole to facilitate the balance of the air pressure of the whole device, and glass cement is arranged at the joint of the funnel 2, the polyethylene plastic hose 3 and the bottle cap for sealing. Placing a filter screen in the funnel 2, cutting into a round shape according to white qualitative filter paper (12.5 cm multiplied by 12.5 cm), folding according to the using method of the filter paper, placing the funnel 2, placing quartz sand or sand for 1-2cm, sealing by glass cement on a bottle cap, and preventing soil particles or leakage liquid from flowing into the bottle from the hole of the bottle cap. Before embedding the device in the soil, the air tightness of the device is detected and a pre-experiment is carried out to ensure that the device can be normally used. The device is buried in soil, at least 10cm of soil is covered on the funnel 2, if the device is buried in a planting hole, the device is located at the corner of the planting hole, and the upper part of the device and the bottom of the seedling soil ball are on the same horizontal line. The port of the polyethylene plastic hose 3 is exposed on the ground, and is sealed by an adhesive tape for the convenience of identification and the prevention of port blockage.

The utility model discloses an operating principle is, buries the device in soil, and record start time when subaerial precipitation or water, water oozes down gradually in the soil space, when oozing down 2 tops of funnel, filters through quartz sand or sand, finally flows into main cavity body 1, treats that 3 outflow waters of polyethylene plastic hose finish watering to record time. If the roots of the seedlings do not know whether accumulated water exists in the roots of the seedlings after a few days of a heavy rain, the seedlings can be directly connected to the hose 3 through the injector to pump water, if water can be pumped out, the roots can be proved to have the accumulated water, and if the water cannot be pumped out, the roots can be proved to have no accumulated water. The utility model discloses can also measure soil permeability, if will measure soil permeability, need hug closely the bottle end with hose 3, can increase in the plastic bottle a small amount of liquid that has the colour so that observe. If the physical characteristics of the planted soil, such as porosity and volume weight, are basically consistent in a certain area, the soil permeability can be measured through tests. When fine management and maintenance are carried out, the moisture condition of the root of the seedling can be comprehensively judged by combining watering time with soil permeability and the condition of time required for pumping water out of the polyethylene plastic hose 3. Water collected in the syringe extraction device can also be used for measuring the content of carbon and nitrogen in soil and carrying out organic matter fluorescence characteristic analysis, and samples are provided for relevant scientific research experiments.
