One Way Of Preventing Herbicide Spraying On Scallion : Assemble A Protective Box With Acrylic Panels
Clarification For The Method Shown In The Video :
It can weld a frame with steel bars.
The size of the frame should match the size of the furrow in the green onion field.
Then, cover the frame with a waste fertilizer bag to create an open structure.
When spraying pesticides, place the nozzle of the sprayer tube inside this open frame.
A person needs to pull the frame at the front, and the person spraying pesticides follows and moves together. This can effectively prevent herbicides from spraying on the green onions !
This method has certain feasibility.Through the shielding of the frame and fertilizer bag, the spraying direction and range can be controlled to a certain extent, reducing the possibility of herbicides spraying on the green onions.
However, in the operation process, some issues also need to be noted :
1. Ensure the stability of the frame to avoid shaking or deformation during the pulling process, which may affect the spraying effect !
2. Fix the fertilizer bag well to prevent it from falling off or shifting during the movement process, resulting in reduced protection effect !
3. The person pulling the frame and the person spraying pesticides need to cooperate tacitly and maintain an appropriate speed and distance to ensure the uniformity and effectiveness of Spraying !
4. When choosing a fertilizer bag, it is best to select a relatively thick and not easily damaged bag to improve the reliability of Protection !
5. After spraying is completed, clean up the residual pesticides on the frame and fertilizer bag in time to avoid polluting the environment !
Besides The Above Method, Hereby We Introduce Other Simple Tool Which Could Prevent Herbicide Spraying On Onions, As Below :
The following are some materials that can be used to make anti-splash devices :
I. Plastic Film
Advantages :
1. Relatively lightweight, easy to operate and install !
2. High transparency, allowing the spraying situation to be observed to a certain extent !
3. Relatively low cost and easy to Obtain !
Usage Method
The plastic film can be cut into an appropriate size and fixed on a frame to form a tent-like structure. Place the nozzle inside for spraying operations !
II. Cardboard
Advantages :
1. Has a certain degree of hardness and can maintain its shape well !
2. Can be cut and folded according to needs to make protective devices of different shapes !
Usage Method :
Use cardboard to make a cuboid or semi-enclosed cover. Leave a hole for the nozzle at an appropriate position. Insert the nozzle for spraying. At the same time, a layer of waterproof coating can be applied on the cardboard to enhance its d ur ability !
III. Acrylic Panel
Advantages :
1. Sturdy and durable with good transparency !
2. Easy to clean and reusable !
Usage Method:
Cut the acrylic panel into an appropriate size and assemble it into a protective box. Open small holes on one or more sides for the nozzle to extend out. This can prevent splashing and also allow observation of the operation situation !
