Directional spraying method for fruit tree

Abstract

The invention discloses a directional spraying method for fruit tree and is characterized in that the directional spraying method for the fruit tree comprises the following steps: a, adopting a directional spraying device, the directional spraying device comprises a box body, a medicine pool, a fan and a spraying nozzle; b, filling the medicine liquid into the medicine pool through the medicine inlet and pushing the directional spraying device in the orchard; c, starting the fan and an ultrasonic atomization assembly, the medicine liquid is atomized into the medicine fog by the ultrasonic atomization assembly, spraying the medicine fog via a spraying soft pipe; the operator can adjust the angle of the spraying soft pipe for aiming the spraying nozzle at the fruits or leaves on the each fruit tree for spraying the pesticide. The directional spraying method for the fruit tree can exactly spray the leaves or fruits with good directing property for guaranteeing the normal growth for the crops, the spraying area is small, thereby the medicine fog will not be blew away by the against wind, the operator can be effectively avoided for poisoning for intake of the medicine fog, and the defect of prior art can be overcome commendably.

Description

technical field [0001] The invention belongs to the field of agriculture and forestry, in particular to a method for directional spraying of fruit trees. Background technique [0002] In order to kill pests, fruit trees need to be sprayed. At present, a knapsack sprayer is generally used to spray pesticides. When spraying pesticides, the spray rod is used to point the leaves or fruits to spray pesticides. The defects of the existing methods are as follows: [0003] 1. In some cases, only the fruit needs to be sprayed, and in some cases, only the leaves need to be sprayed. However, the spraying range of the current sprayer is too large and the directionality is poor. This will affect the growth of fruit trees or the quality of fruits, etc., which is not conducive to agricultural production; [0004] 2. Due to the poor orientation and the large spraying area, if there is a headwind, the spray may blow to the operator, which may cause the operator to be poisoned. Contents o...
