FIELD: agriculture.
SUBSTANCE: group of inventions relates to versions of devices for application of introduced material in form of fluid medium on plants in agricultural fields. In all versions, the device comprises a frame arranged during operation between the first and second rows of plants. In the first version, the device also contains a first element in contact with the plant, which is hingedly connected to the frame during operation so that the first element in contact with the plant deviates back relative to the direction of movement of the frame at contact of the first element in contact with the plant with at least one of plants from the first row plants, that causes first change of orientation of first element in contact with plant relative to frame; as well as a first outlet for application of liquid introduced material on the first row of plants. First outlet is mechanically connected to the first element contacting with the plant. First change of orientation causes the corresponding second change of orientation of the first outlet relative to the frame. In another version, the device comprises a base element connected to the frame. Base element should be located near ground surface during operation; device also comprises first and second planting elements connected to the base element during operation such that the first and second plant directing elements direct the base base lateral position, that it is approximately equidistant from two rows of plants on the basis of whether at least one of the first and second direction elements is contacting plants with one or more plants from two rows of plants. In the next embodiment, the device also comprises a base member connected to the frame; and at least one fluid delivery lever element connected to the base member during operation by means of the biasing member such that the biasing member displaces the angular position of the at least one lever member. In the next version, the device also comprises a first plurality of flexible elements connected to the frame during operation, such that the first plurality of flexible members directs the frame side position, that it is approximately equidistant from two rows of plants on the basis of whether at least one of the first plurality of flexible elements is in contact with one or more plants from two rows of plants.
EFFECT: ensuring accuracy of application on required area.
