In the planting and management of dwarf orchards such as jujube orchards, kiwifruit orchards, and grape orchards, pesticide spraying is a core link in pest and disease control, which directly affects orchard yield and fruit quality. Dwarf orchards generally have the characteristics of narrow plant spacing and high fruit tree density, which puts forward higher targeted requirements for the size, power, and functions of self-propelled pesticide sprayers. Choosing a suitable self-propelled pesticide sprayer can not only greatly improve the efficiency of field pesticide application, ensure uniform coverage of pesticide liquid, but also effectively save pesticide and labor costs, escorting the high yield of dwarf orchards. Combining the actual planting scenarios and pesticide application needs of dwarf orchards, this article details the core selection points of self-propelled pesticide sprayers to help fruit farmers quickly select suitable equipment.
Combined with the spatial characteristics of dwarf orchards such as jujube orchards, kiwifruit orchards, and grape orchards, as well as the actual needs of orchard pest and disease control, the selection of self-propelled pesticide sprayers should focus on six core dimensions: body size, power type, pesticide barrel capacity, spraying height, atomization effect, and pesticide dosage adjustment. The specific selection points are as follows:
1.Small-sized body, suitable for narrow plant spacing: The gaps between fruit trees in dwarf orchards are limited. An excessively large body is easy to scratch fruit tree branches and leaves, hinder field movement, and affect pesticide application progress and fruit tree growth. The small self-propelled pesticide sprayer has a compact body and flexible steering, which can easily shuttle between fruit tree rows without repeatedly adjusting the operation route, greatly improving field operation efficiency. It is especially suitable for dense-planted dwarf orchards such as jujube orchards and kiwifruit orchards, which is the preferred choice for dense-planted orchard pesticide spraying equipment, and also fully meets the use needs of narrow-row self-propelled sprayers.
2.Gasoline-powered, dual advantages of portability and energy supplement: Most dwarf orchards are planted outdoors, and some orchards are remote and inconvenient to connect to electricity, so gasoline-powered self-propelled pesticide sprayers have become the preferred choice. Compared with electric and diesel models, gasoline pesticide sprayers are lighter in body, easier to flexibly transfer operation areas in the orchard, and gasoline energy supplement does not rely on fixed power sources, which can be supplemented anywhere in the field, completely solving the energy supplement problem of remote orchards. It is suitable for pesticide application operations in various outdoor dwarf orchards, perfectly fits the use scenario of gasoline self-propelled sprayers, and is also an ideal choice for outdoor orchard pesticide spraying equipment.
3.Large-capacity pesticide barrel, reducing repeated pesticide addition: The area of orchard pesticide spraying operations is usually large, and repeated pesticide addition will seriously consume operation time and affect the continuity of pesticide application. The self-propelled pesticide sprayer with a large-capacity pesticide barrel can load more pesticide liquid at one time, reduce the frequency of repeated pesticide addition in the field, and make the pesticide spraying operation more coherent and efficient. It is especially suitable for the centralized pesticide application needs of large-area dwarf orchards such as jujube orchards and grape orchards, which can not only improve operation efficiency, but also meet the use standards of large-capacity self-propelled pesticide sprayers, and adapt to the operation requirements of orchard centralized pesticide application equipment.
4.Spraying height of about 4 meters, covering the entire fruit tree: The plant height of dwarf fruit trees such as jujube, kiwifruit, and grape is generally suitable for a spraying height of about 4 meters. The self-propelled pesticide sprayer with height adjustment function can flexibly adjust the spraying height to the suitable range, realizing uniform spraying from the bottom to the top of the fruit tree, without manual adjustment of the spraying angle, ensuring that the branches, leaves and fruits of the fruit tree can be evenly coated with pesticide, greatly improving the effect of pest and disease control. It is a high-quality model of height-adjustable sprayers, and also fully adapts to the use needs of full-area pesticide application equipment for fruit trees.
5.High atomization effect, improving pesticide liquid adhesion rate: The atomization effect directly determines the pesticide application effect and pesticide utilization rate. The high-atomization self-propelled pesticide sprayer can decompose the pesticide liquid into fine droplets with uniform particle size, which can better adhere to the surface of crop branches, leaves and fruits, avoiding waste caused by the accumulation and sliding of pesticide droplets. It not only ensures the accuracy of pest and disease control, but also can effectively save pesticides, adapting to the needs of refined pesticide application in dwarf orchards. It is a preferred model of high-atomization sprayers and meets the industry standards of refined orchard pesticide application equipment.
6.Adjustable pesticide dosage, saving cost by applying pesticide on demand: In dwarf orchards, the demand for pesticide dosage varies with the growth stage of fruit trees and the severity of pests and diseases. The self-propelled pesticide sprayer equipped with the pesticide dosage adjustment function can flexibly adjust the pesticide output according to the growth stage of fruit trees (young tree stage, mature tree stage) and the severity of pest and disease outbreaks, realizing precise pesticide application and on-demand pesticide application, saving pesticide costs from the source, reducing the agricultural input of dwarf orchard planting. It is a high-quality model of adjustable pesticide dosage sprayers and adapts to the use needs of energy-saving orchard pesticide application equipment.
