Description

A plant root pest investigation sampler

technical field

The invention relates to the fields of plant protection and ecological investigation, in particular to an investigation sampler capable of investigating and sampling plant root pests, ensuring the integrity of the sampling root system and root pests, and preventing the pests from escaping.

Background technique

The root system is the main organ for plants to absorb nutrients and water. The absorption of nutrients by the roots of plants is the core of plant nutrition. If there is a problem with the root system of a plant, the yield will be reduced in the slightest, and the harvest will be wiped out in the severest case. Timely monitoring, detection of epidemics, and targeted prevention and control measures are important technical means to improve crop yield. Therefore, it is an important technical means to determine whether the plant root system is healthy or not to carry out sampling investigation on the development, disease and insect damage of the plant root system. In the process of investigation and sampling, the standardization and completeness of samples can objectively reflect the actual situation. Therefore, a sampling device that is easy to operate and can ensure the standardization and completeness of samples is needed in the process of root pest sampling investigation.

In the prior art, the sampler for the investigation and sampling of plant root soil, such as the patent document of "the announcement number is CN205175729U, the name is: field rice root system sampling device", "the announcement number is CN204350914U, the name is: a soil insect sampler "The cylindrical shape with upper and lower openings is often used as the main body of the sampler. As a relatively closed space, the cylindrical body does prevent root pests from escaping to a certain extent, but it is extremely inconvenient to operate during sampling. Most plants are cut off and then sampled. , some samplers need to put the plant into the sampling tube, and then insert the sampling tube into the soil for sampling; whether it is cutting off the ground part of the plant or putting the plant into the sampling tube, it will exert force on the plant body, and The force is quickly transmitted to the pests by the root system of the plant, and the sensitive pests will escape quickly, resulting in inaccurate sampling, and thus the inability to accurately determine plant problems.

Take rice water weevil as an example: rice water weevil belongs to Coleoptera Weevilidae and is a destructive rice quarantine pest. It is listed as the world's 100 most threatening alien invasions one of the creatures. Host: rice, English white, corn, sugarcane, wheat, barley, forage, grass weeds, etc. Adults eat the leaves and eat the mesophyll along the veins of the host plant. When the damage is serious, the mesophyll will be eaten up, leaving only a layer of skin; the larvae will eat the rice roots and destroy the root system of the rice. Reducing the number of panicles per unit area and delaying the growth period of rice will seriously affect the growth and development of rice.

Both rice water weevil larvae and adults can cause great damage to the parasitic plants, and if it is a little serious, it can cause plant production reduction or even extinction. And to the monitoring of rice water weevil pupae and larvae, in the prior art, adopt directly to pull out rice root system when survey sampling, cause root system to break off, larvae and pupae are intercepted field soil, and sampling can not objectively reflect the generation situation of pest damage, adopts The sampler can effectively solve the interception of larvae and pupae and ensure the reliability of sampling.

Contents of the invention

In order to solve the sampling method for investigating and sampling plant root pests in the prior art, which may cause technical problems such as incomplete sampling of root pests and escape of pests during the sampling process, the present invention provides a method that can effectively ensure the sampling of root pests.

Detailed ways

Below in conjunction with accompanying drawing, the present invention will be further described:

A sampler for plant root investigation, comprising a sampling cylinder and a handle 1, characterized in that the sampling cylinder is a cylindrical structure with 6 incisions, and the transition from the bottom part of the cylinder and the 6 incisions to the cylinder wall is from thin to thick. The cutting edge structure, the upper bottom surface of the sampling cylinder is designed with at least a semi-circular plug 9, the outer arc of the plug 9 matches the inner wall of the sampling cylinder; the mounting rod 3 is vertically fixed on the cylinder wall, and the horizontal The handle 1 is fixedly installed above the sampling cylinder through the installation rod 3, and the handle 1 and the installation rod 3 are in a T-shape.

During use, because the lower end of the sampling cylinder is the lower cutting edge 7, the sampling cylinder at the incision is in the structure of the side cutting edge 5, and the plant body is brought into the sampling cylinder from the incision 6 of the sampling cylinder. Then hold the handle 1 and quickly cut the sampling tube vertically into the soil. After the soil surface reaches the uppermost end of the sampling tube, press the handle 1 down a few times. Under the action, at least the half-circle of the plug 9 along the side wall is in a compacted state; the handle 1 is slightly lifted to make the wall of the sampling cylinder higher than the soil surface, and then the handle 1 is rotated to drive the sampling cylinder to rotate in situ, that is, Under the action of the cutting edge at the incision 6, the rotating sampling cylinder makes the soil be cut into a complete cylindrical soil block. At this time, the sampling cylinder is taken out, and the soil in the sampling cylinder can be taken out, realizing the function of the sampler to take out the plant root system soil. The design of the plug 9 is extremely necessary. Only the existence of the plug 9 can make the soil near the inner side wall of the sampling cylinder in the sampling cylinder be compacted more tightly than the soil at the center of the sampling cylinder under the action of force. When the sampling cylinder is raised, the dirt is brought out.

Through the existence of the sampling cylinder cutout 6, the plants can be quickly included in the sampling cylinder during the sampling process. During the sampling process, the plant body will not be touched, thereby avoiding the transmission of force to the plant root system due to the plant being touched, and make pests escape. In the process of inserting the sampling cylinder into the soil, although the sampling cylinder also has a strong effect on the soil, because the resistance of the soil to the pests is far greater than the resistance of the plants to the pests through the root system, the pests are more likely to feel the plant The force transmitted to the roots by being touched causes the escape of pests.

Further, a desilting sheet is also designed in the sampling cylinder, and the desilting sheet can slide up and down along the inner wall of the sampling cylinder. It is necessary to fully collect the plant root system and the soil around it, and then manually sort or clean and filter, so that all the pest eggs and larvae in the soil can be separated, and the statistical data is used to calculate. When the sampled soil has a certain When there is too much viscosity or moisture, it is easy to stick to the inner side of the cylinder wall. The design of the desilting sheet can easily remove the soil in the sampling cylinder.

Further, the outer curved surface formed by the desilting sheet matches the inner surface of the sampling cylinder. The outer curved surface of the desilting sheet is designed to match the inner surface of the sampling cylinder. Under the action of the desilting sheet, all the soil adhered to the side wall of the sampling cylinder can be removed. The desilting sheet can be ring-shaped or can be It is formed after two moon-shaped plates are overlapped. As long as the outer surface can match the inner surface of the sampling cylinder, the purpose of taking out the soil in the sampling cylinder can be achieved more thoroughly.

Further, the thickness of the outer surface of the arc corresponding to at least 1/4 of the arc length of the desilting sheet is greater than 1/6 of the diameter of the sampling cylinder. The thickness is designed to ensure that the desilting sheet will not be distorted inside the sampling cylinder due to uneven force, so that the outer surface does not fit the inner surface of the sampling cylinder, so that the soil cannot be taken out quickly.

Further, the desilting sheet can be designed as multiple sets of anti-deflection claws on the upper surface of the plate body, near the outer surface, and perpendicular to the plate body, and the outer surfaces of the anti-deflection claws are attached to the inner wall of the sampling cylinder.

Further, in order to make the effect of the mud removal sheet better, the mud pusher rod 8 is also included, and the mud pusher rod 8 assists in applying force when pushing out the mud removal sheet, so that the mud removal sheet can be more smoothly released from the soil in the sampling cylinder.

Further, in order to cooperate with the force of the mud pusher 8, a force hole for the mud pusher 8 is designed on the upper surface. After placing one end of the mud pusher 8 in the force hole, and apply force to the mud pusher 8, it can be quickly and cleanly Remove the soil from the sampling cylinder.

Further, in order to cooperate with the mud push rod 8, it also includes the mud push rod 8, the sampling cylinder and the desilting track, the wall of the sampling cylinder is designed with two axial desilting plate 4 tracks, and the sampling cylinder After the inner body of the desilting plate 4 passes through the track of the desilting plate 4, it is connected with the mud pushing rod 8 on the outside of the sampling cylinder.

Further, the installation position of the installation rod 3 is at the intersection of the sampling cylinder and the straight line formed by connecting the center point of the arc length at the notch 6 of the sampling cylinder and the center of the circle. The position of the mounting rod 3 ensures that the sampling cylinder on the side of the mounting rod 3 becomes symmetrical, and the structure is easier to force.

Further, it also includes an even number of force component rods, the rod body of the installation rod 3 is fixedly connected to the installation end of the force force rod, and the other ends of the force force rod are respectively symmetrically fixed on the cylinder wall of the sampling cylinder. When the sampler is working, it needs to be rotated because of the existence of the notch 6. At this time, the force component rod can transmit the torque of the handle 1 to the cutting edge at the notch 6 more conveniently, so as to realize the rotation. If there is only one mounting rod 3, the connection between the mounting rod 3 and the handle 1 or the sampling cylinder will be disengaged due to excessive force during the rotation process, which will affect the overall life of the sampler.

Further, a C-shaped bend 2 with an arc transition is designed in the middle of the installation rod 3, and the notch faces the outside of the sampling cylinder. The design of the C-shaped bend 2 enables the force of the handle 1 to be more evenly transmitted to the bottom and side of the sampling cylinder, saving more effort during sampling.

Further, on the inner side wall of the sampling cylinder, a concave slot is designed in the axial direction, the width of the slot is smaller than the width of the bottom of the slot, and an inflatable sealing strip is laid in the slot. When the soil temperature is high, especially when sampling paddy fields, the soil around the roots of the plants sampled will form a mud shape, and the mud-like soil will form a mud-like sticky effect in the sampling cylinder after being taken out. , it needs a great force to realize it, but in this patent application, the inflatable sealing strip is inflated before taking the paddy field soil sample. A certain air gap is formed between the side walls of the cylinder, which destroys the viscous effect of the impermeable sludge, and the sludge in the sampling cylinder can be taken out more quickly.

The scope of protection of the present invention is not limited to the technical solutions disclosed in the specific embodiments. The above descriptions are only preferred embodiments of the present invention and cannot be interpreted as limiting the scope of protection of the present invention. Minor modifications, equivalent replacements and improvements shall all be included within the protection scope of the technical solution of the present invention.
