Greenhouse agriculture creates a controlled production environment, but crop protection and liquid fertilizer application still require practical spraying equipment. Protected growing areas can impose tighter operating constraints than open fields, particularly where machinery must move through restricted working spaces, turn efficiently, and direct spray toward crops without requiring the operator to remain immediately beside the machine.
For greenhouse spraying operations, equipment selection therefore needs to consider the working environment, crop arrangement, required spray direction, machine dimensions, maneuverability, control method, and application requirements.
Remote-control self-propelled boom sprayers provide one approach for greenhouse agriculture. Instead of requiring the operator to stay on the machine during spraying, the supplied Duojia equipment uses remote control operation. The 3WYP-50B is specifically described for facility greenhouse spraying and fertilization, while the 3WYP-40 is described for spraying facility crops and can adjust its boom for horizontal or vertical spraying.
This application page focuses on how these remote-controlled self-propelled sprayers can be considered for greenhouse crop protection and liquid fertilizer application, and what professional buyers should evaluate before selecting equipment.
Application Scope
This solution is focused on spraying operations in protected agricultural environments, particularly:
Greenhouse crop spraying
Facility crop protection
Liquid fertilizer spraying in greenhouse operations
Insecticide application
Fungicide application
Herbicide application where appropriate to the production system
Remote-controlled plant protection operations
Spraying operations requiring horizontal or vertical spray orientation
The supplied product information specifically identifies the 3WYP-50B for facility greenhouse spraying and fertilization. The 3WYP-40 is described for facility crops as well as open-field crops and provides adjustable horizontal and vertical spraying.
The actual application configuration should be selected according to the greenhouse layout, crop arrangement, spraying objective, access conditions, and required boom configuration.
Crop and Working Environment
Greenhouse agriculture differs from conventional open-field production because crops are grown within a managed physical environment. Structures, crop rows, growing beds, access paths, and other greenhouse features can influence how spraying equipment moves and how spray is directed.
A suitable greenhouse sprayer therefore needs to match the physical working environment rather than simply provide spraying capability.
Important considerations include:
Available access space for the machine
Greenhouse passage dimensions
Crop arrangement and accessibility
Required spray direction
Need for horizontal or vertical application
Turning requirements at the end of an operating path
Operator position during spraying
Machine dimensions and ground clearance
Required travel speed for the specific operation
Compatibility with the intended spraying task
The supplied 3WYP-50B has a narrow, low-center-of-gravity machine configuration and can perform in-place turning. Its dimensions are 1050 × 580 × 1650 mm, with a vertical spray boom height of 2000 mm. An optional horizontal spray boom has a length of 3500 mm.
The 3WYP-40 measures 1020 × 3600 × 2020 mm and has a 110 mm ground clearance. Its 3.5 m spray boom can be adjusted for horizontal or vertical spraying.
These dimensions are product specifications rather than universal greenhouse requirements. Buyers should compare them against the actual greenhouse layout before procurement.
Agricultural Operation
The main agricultural operations supported by the supplied information are greenhouse crop spraying and liquid fertilizer application.
Crop Protection Spraying
The 3WYP-40 is described for facility crops and can be used for spraying herbicides, insecticides, fungicides, and water-soluble fertilizer. The 3WYP-50B is described for facility greenhouse spraying and fertilization.
The appropriate application program, chemical product, concentration, and application rate should be determined by the grower's agronomic requirements and applicable local regulations. The machinery itself should be selected based on whether its spraying configuration can deliver the required application pattern and access the target crop.
Horizontal and Vertical Spraying
Greenhouse crops can present different spray-direction requirements depending on crop structure and machine access.
The 3WYP-40 provides boom rotation adjustment for horizontal and vertical spraying. The 3WYP-50B provides a vertical spray boom and an optional horizontal spray boom.
This configuration flexibility can be relevant when a greenhouse operation needs to direct spray toward different crop zones rather than relying on one fixed spraying orientation.
Liquid Fertilizer Application
The supplied information identifies the 3WYP-50B for greenhouse spraying and fertilization and identifies the 3WYP-40 for spraying water-soluble fertilizer.
The equipment should be configured and operated according to the characteristics of the selected fertilizer product and the greenhouse production requirements.
Application Challenges
Greenhouse spraying can involve several practical equipment challenges.
Restricted Machine Access
Greenhouse structures and crop layouts can limit available machine paths. Equipment that is too large or difficult to maneuver may not fit the intended operating environment.
Maneuverability
Frequent changes in direction can make machine handling important. The 3WYP-50B uses four-wheel drive and in-place steering, while the 3WYP-40 uses two-wheel drive and front-wheel steering.
These different configurations provide buyers with distinct machine-selection considerations.
Operator Exposure
Spraying operations can place operators near the application area. Remote control allows the operator to control the supplied machines from a distance rather than remaining directly on the spraying machine.
This can support physical separation between the operator and the machine during spraying, although appropriate personal protective equipment, chemical-handling procedures, ventilation, and local safety requirements remain necessary.
Application Direction and Coverage
Greenhouse crops can require different spray orientations. A machine with adjustable or configurable spraying equipment may provide greater flexibility for the intended application.
The 3WYP-40 supports horizontal and vertical boom adjustment. The 3WYP-50B has a vertical spray boom and an optional horizontal spray boom.
Application Consistency
Uniform spraying depends on machine setup, nozzle condition, pressure, boom configuration, travel movement, crop structure, and operating conditions. The supplied products specify a working pressure range of 0.2–0.5 MPa, but actual operating parameters should be established according to the equipment configuration and application requirements.
Technical Requirements for the Application
Greenhouse spraying equipment should be evaluated against the physical and operational requirements of the protected growing environment.
Machine Dimensions and Access
The machine needs to physically access the intended greenhouse operating areas. Buyers should compare equipment dimensions with greenhouse entrances, paths, crop rows, and turning areas.
Maneuverability
A compact and maneuverable machine can be important where operating space is constrained.
The 3WYP-50B uses four-wheel drive and in-place steering and has a stated travel speed range of 0–3 km/h. These specifications should be considered alongside the actual greenhouse layout and operating procedure.
Spray Configuration
The spraying system should match the direction and coverage required by the crop arrangement.
For example, the 3WYP-40 has a 3.5 m boom with adjustable horizontal and vertical spraying. The 3WYP-50B has a 2000 mm vertical spray boom and an optional 3500 mm horizontal spray boom.
Remote Control
Remote operation can be relevant when the operator needs to control the machine from outside the immediate spraying position.
The 3WYP-40 has a stated effective remote-control distance of up to 500 m. The actual usable operating distance should be assessed according to the greenhouse environment and operating conditions.
Spray Pressure
Both supplied machines specify a working pressure range of 0.2–0.5 MPa. Pressure selection should be matched to the spraying system and application requirements rather than treated as a universal setting.
Machine Stability and Access
Machine dimensions, drive configuration, steering method, ground clearance, and greenhouse pathways should be considered together. The objective is to select a machine that can physically access the operating area while providing the required spraying configuration.
Recommended Agricultural Solution
For greenhouse agriculture, a remote-control self-propelled boom sprayer can be considered when the application requires a mobile spraying platform, remote operation, and a spraying configuration suitable for the protected crop environment.
The solution relationship can be summarized as:
Greenhouse spraying requirement
→ Need for practical machine access and controlled operation
→ Remote-control self-propelled sprayer
→ Configured horizontal or vertical spraying according to the application
→ Application of crop protection products or liquid fertilizer
The 3WYP-50B is the more directly aligned option for the supplied greenhouse application because its product information specifically identifies facility greenhouse spraying and fertilization.
The 3WYP-40 can also be considered where facility-crop spraying is required and where its machine dimensions, boom configuration, remote-control system, and two-wheel-drive/front-wheel-steering arrangement fit the operating environment.
The final choice should be based on the actual greenhouse layout and spraying requirements rather than on the product category alone.
How the Agricultural Solution Works
The supplied machines combine a self-propelled chassis with a spraying system and remote-control operation.
During an application, the operator controls the machine remotely while the self-propelled platform moves through the designated operating area. The spraying system delivers the application through the machine's spray equipment.
The main product-specific characteristics are:
Remote-control operation
Self-propelled machine configuration
Spray tank
Spray boom
Spray-pressure operating range
Machine drive and steering system
Configurable spray orientation on applicable models
The 3WYP-40 uses two-wheel drive and front-wheel steering. Its spray boom is 3.5 m long and can be rotated for horizontal or vertical spraying.
The 3WYP-50B uses four-wheel drive and in-place steering. It has a 50 L spray tank, a 2000 mm vertical spray boom, and an optional 3500 mm horizontal spray boom.
Both models specify a working pressure range of 0.2–0.5 MPa.
