Injection fertilization and pesticide application device for preventing and controlling diseases and pests of fruit tree root systems

Abstract

The invention discloses an injection fertilization and pesticide application device for preventing and controlling diseases and pests of fruit tree root systems. The injection fertilization and pesticide application device for preventing and controlling the diseases and pests of the fruit tree root systems comprises a liquid storage tank, an injection piece, a piston piece and a transfer piece, wherein an injection cavity is formed in the injection piece, the bottom of the injection cavity is sunken downwards to form a piston cavity, a first outlet penetrates through the piston cavity, and the first outlet is used for being inserted into a soil layer where a plant root system is located; the piston piece is of a hollow structure and comprises a piston body and a protruding part arranged on the side face of the piston body in a surrounding mode, the protruding part is arranged in the injection cavity in a sliding mode and divides the injection cavity into an air inlet cavity and a liquid inlet cavity, a piston liquid inlet and a piston liquid outlet are formed in the piston body, the piston liquid inlet communicates with the liquid inlet cavity, and the piston liquid outlet is used for communicating with the first outlet; the liquid storage tank sequentially communicates with the transfer piece and the liquid inlet cavity of the injection piece. According to the injection fertilization and pesticide application device for preventing and controlling the diseases and pests of the fruit tree root systems, pesticide liquid can be accurately sprayed into the soil layer where the plant root system is located, the application effect of the pesticide liquid is improved, and the cost is saved.

Description

technical field [0001] The invention relates to the field of plant root irrigation equipment, in particular to an injection fertilization and drug application device for preventing and controlling fruit tree root system diseases and insect pests. Background technique [0002] In the production of fruit trees, fruit growers often neglect the prevention and control of the root diseases and insect pests of fruit trees. After the root of the fruit tree becomes ill, the leaves and fruits of the light ones will fall off in the early stage, and the growth will be poor. Therefore, plants need to apply drugs in a timely and accurate manner during the planting process. The current method of controlling the roots of fruit trees can be spraying pesticides on the surface or using pesticides to irrigate the roots. However, the method of spraying pesticides on the surface will not really penetrate into the roots. To the leaves and fruits, it will also cause damage and pollution to healthy ...
