Innovative method of strip-till 3-D spraying in chemical treatment of crops to implement resource-saving approaches in strip-till technology

Abstract

A new approach to the technology of chemical treatment of crops based on the technological process of volumetric 3-D spraying, which differs favorably from the classical technology of continuous spraying, is developed. The development makes it possible to competently and efficiently apply working chemical solutions depending on the phase of growth and development of the cultivated plant on the object of treatment. When designing the technological process of volumetric 3-D spraying, the architectural features of the cultural plant were taken into account. The applied approach to the application of the working solution to the plant allows combining the methods of solid and strip spraying. For this purpose, a technical solution is offered to retrofit a serial boom sprayer with special bodies for separation of liquid flows and directing the liquid to the object of treatment. In this case a new, more stable flow in width and height is formed. The paper considers the results of studies of the technological process of chemical treatment with the use of strip technology in terms of quality indicators. The technical solution makes it possible to perform fast equipment adjustment in the field without using special tools. At the same time, it is possible to switch from solid spraying to strip spraying and vice versa. When switching to strip spraying, the spray solution is sprayed strictly along the strips of the crop and covers the entire surface of the stem and leaves. This allows you to reduce the cost of applying liquid chemicals and accurately redistribute the spray solution. As a result of the technology the goals of reducing costs, improving the quality of chemical treatment and increasing the environmental friendliness of the chemicalization process are achieved.

Robot for strip spraying of vegetable crops

“…When carrying out the technological process of spraying agricultural crops, one of the main requirements is the uniformity and accuracy of the distribution of pesticides, the introduction of liquid forms of pesticides and fertilizers using robotic tools contribute to a more uniform distribution over the treated area and achieve the required accuracy of getting to the processing object [10].…”
