Accurately targeted drug applying device and method for fruit tree rootstock

Abstract

The invention relates to an agricultural drug applying device, in particular to an accurately targeted drug applying device for fruit tree rootstock. The device comprises a system carrying platform, a locating and identifying subsystem, a targeted drug applying subsystem and a distribution map generating subsystem. According to growing characteristics of the fruit tree rootstock, a portal frame type moving platform is adopted; a scanning type laser range finder, machine vision and GPS (global positioning system) are combined together to quickly and effectively locate and identify the fruit tree rootstock, therefore a multi-nozzle drug applying system is controlled to finish the targeted drug applying operation, and meanwhile the distribution map of the fruit, the rootstock and the drug applying amount is generated. The accurately targeted drug application to the fruit tree rootstock can be implemented; the pesticide usage amount is effectively reduced; the drug liquid utilization ratio is improved; the environment pollution is reduced; and scientific skills can be provided for the orchard digital management in the future.

Description

technical field [0001] The invention relates to an agricultural pesticide application device, in particular to a device for accurately targeting fruit tree roots and tillers. Background technique [0002] Fruit tree root tillers are non-fruiting twigs, vines or branches that grow from the roots of fruit trees. Generally, they come out from latent buds at the roots of fruit tree trunks, which convert a part of the important nutrients of the plant into useless growth. In order to ensure the effective growth of fruit trees and obtain sufficient nutrition, and to avoid affecting other orchard operations, it is very necessary to remove the root tillers. Throughout the growing season of fruit trees, root tillers will continue to grow, so it is also required to remove root tillers many times. [0003] The traditional root tiller removal method is manual removal, and the root tiller is removed from the trunk by pruning with sharp tools such as a knife. Although this method can com...

Problems solved by technology

In the past, fruit farmers used manual methods to obtain such information. This method was labor-intensive, extremely inefficient, and the accuracy of the information was not high. Some fruit farmers even gave up obtaining this information because of this, which led to the slow development of large-scale economic forests in my country.

At present, many scholars and researchers at home and abroad use airborne surveying and mapping systems to draw agricultural and forestry information maps. growth size and location of tree root tillers, etc.)
