Description

Handheld spartina alterniflora pulling-out auxiliary tool

Technical Field

The utility model belongs to the technical field of environmental protection, and particularly relates to a handheld spartina alterniflora pulling auxiliary tool.

Background

Spartina alterniflora (Spartina alternifloraLoisel) belongs to gramineae, spartina, is a perennial herbaceous plant, originates in the atlantic coast of america and in the gulf of mexico, and is suitable for living in intertidal zones. The spartina alterniflora straws are dense and strong, underground roots and stems are developed, and rapid sedimentation and siltation of silt can be promoted, so that the spartina alterniflora straws are introduced in sequence in many countries for protecting banks in beaches and promoting silt to build land. China starts introduction in 1979, and is widely popularized to coastal mudflats such as Guangdong, Fujian, Zhejiang, Jiangsu, Shandong and the like after successful test in 1980. Because the propagation expansion capacity is strong, natural enemies and other restriction factors do not exist in China, the growth and the diffusion of the ecological system can be controlled, the ecological system is flooded to coastal wetlands in China to cause disasters at present, and the ecological system is expanded crazy continuously, so that the ecological system has great influence on the structure and the function of the coastal wetland. In 2003, Spartina alterniflora was listed by the State environmental protection Bureau as the first 16 foreign species invading China. In 2021 month, the department of agricultural rural areas, the department of natural resources, the department of ecological environment, and the like, jointly issue a "further enhancement of foreign species invasion prevention and control working scheme", and propose "catching major forest grass foreign invasive species management such as pine wood nematodes, fall webworms, spartina alterniflora, mikania micrantha, and the like, in combination with construction of relevant ecological protection and restoration projects".

At present, the method for treating spartina alterniflora mainly comprises a harvest covering method, a harvest flooding method, a herbicide spraying method, a physical digging method and the like. The first two methods have small risk of secondary pollution, but the working period is long, and the application of the herbicide is difficult to popularize and use in a large range due to the worry of adverse effects on other organisms. The excavation method is to excavate the root and the soil together with a tool such as a machine, and the work load and the influence on the local soil structure are large, so that the excavation method is not favorable for large-area use. From the aspects of economic cost and ecology, no practical technology for large-scale treatment of the spartina alterniflora in a piece-by-piece distribution is available at present, so that from the perspective of spartina alterniflora prevention and control, newly germinated plants or newly grown plants in uninvaded areas can be found as early as possible and immediately removed, and the method is one of effective methods for preventing further spreading and expanding of the plants. As the roots of the spartina alterniflora are extremely developed, the fibrous roots are often densely distributed in a soil layer with the depth of 30 cm underground, and the main roots can sometimes be as deep as 50-100 cm. Therefore, it cannot be removed directly by hand.

The handheld spartina alterniflora pulling auxiliary tool designed by the utility model can manually pull out spartina alterniflora plants of less than 2 years old, especially newly germinated short-lived spartina alterniflora plants, and is particularly suitable for prevention and control of newly invading spartina alterniflora in coastal wetlands (such as intertidal zones).

Disclosure of Invention

The utility model aims to design a handheld auxiliary tool capable of conveniently and effectively pulling out spartina alterniflora to realize prevention and control of invasive spartina alterniflora.

The structure of the handheld spartina alterniflora pulling auxiliary tool designed by the utility model is shown in figure 1, and comprises: the device comprises a middle vertical rod 1, a root breaking device 2, a mud poking device 3, a pedal 4 and an upper cross rod 5; wherein, the root cutter 2 is positioned at the lower end part of the middle vertical rod 1 and is fixed; the upper cross rod 5 is fixed at the upper end of the middle vertical rod 1 and is used for holding the tool by hand and controlling the rotation operation of the root cutter 2; the two pedals 4 are arranged on two sides of the connecting part of the middle vertical rod 1 and the root cutter 2 and used for providing supporting points for pedal force, and the root cutter 2 is inserted into soil around the spartina alterniflora plant; the root cutter 2 is cylindrical, an opening 6 is arranged beside the cylindrical root cutter and used for placing the spartina alterniflora plant into the cylinder, and the lower end of the root cutter 2 is zigzag and can be used for cutting off the spartina alterniflora root hair; the mud poking device 3 is positioned inside the root cutting device 2 and can move up and down in the root cutting device 2, and two sides of the upper end of the mud poking device 3 are respectively provided with an outward protruding structure 7; when the external root cutter 2 is inserted into soil, the mud poking device 3 automatically rises, and when the root cutter 2 is pulled out, the protruding structure on the upper part of the mud poking device 3 is lightly stepped by one foot, so that the soil can be left in the original position while the external root cutter 2 is pulled out.

The operation of the utility model is as follows:

holding the upper cross rod of the tool by two hands, placing the tool at the ground-near base of the plant of the spartina alterniflora to be pulled out, placing (plugging) the plant into the lower port of the root cutter, then forcibly treading the pedals at the two sides of the root cutter by feet until the root cutter is completely inserted into the soil, rotating the upper cross rod for 2-3 times at 360 degrees left and right to drive the soil-entering root cutter to rotate, and cutting off the connection between the fibrous roots of the plant and the soil outside the root cutter; then holding the upper cross bar by hand and shaking left and right (inclining to an angle larger than 60 degrees with the ground) for 2-4 times to loosen the soil in the root cutter; then holding the near-ground base of the plant by hand, forcibly pulling out the whole plant, shaking off the soil carried by the root and then collecting the plant; and finally, lightly treading the upper protruding structure of the internal mud poking device by feet, simultaneously pulling out the root breaking device, treading the ground with the feet after pulling out the plants, and compacting the soil to finish one-time operation.

The utility model has simple structure and convenient use, can quickly and efficiently pull out the spartina alterniflora, and is particularly suitable for preventing and controlling new invasion of the spartina alterniflora in coastal wetlands (such as intertidal zones).
