![]() Tipping a plug flat toward the transplanter can reduce the distance by as much as 10”. ![]() The farther you have to reach for something, the more time it takes. Materials should be located as close to the work area as possible. A level of 40 to 60 foot-candles is necessary. It should be located above the workstation so as not to create shadows. Space to the rear should be left for movement of workers and materials.Īdequate lighting over the work area will increase efficiency and reduce eye strain. Assembly area is best within 16” to 18” of the resting elbow position.Ī space of 3’ x 3’ is normal for the worker unless a wider work area for supplies is needed. The reach from the normal arm rest position should be limited to 24” radius to the side and front for women and 27” for men. Start and stop motions require more energy and time. If reaching for plants or other things, the distance should be the same for both hands.Ĭontinuous or curved motions are the most natural and productive. Holding something in one had while the other hand is performing a task is not very productive. Where possible, both hands should operate as mirror images and both be working at all times. Comfortable chairs with back and foot rests will create less fatigue. Height adjustment in the chair or stool can bring the worker up to the standing height level. It is best to provide for both standing and sitting positions as greater efficiency is achieved when workers change positions.Įlbow height should be measured in the standing position. Adjustment should be provided for different size workers. The following basic principles should be followed if possible: It should include the location of the worker, materials and tools. Finished product ( transplanted container)Ī drawing should be made on graph paper to scale to develop the best layout. Incoming materials (example, prefilled container, transplants, tags, product to be graded, etc.)ģ. The following should be included in any workstation design:Ģ. A reduction of 20 to 30 percent in time is often the result. These same principles can be used to improve many of the tasks associated with growing plants. The layout of this area can have a large influence on the efficiency of the work that is accomplished.īasic principles of workstation design and layout have been developed based on time and motion studies and these have been applied to many industrial operations and tasks. Movement of the transplanted plants can be with carts or a conveyor system.Ī workstation is an area where an employee does a series of repetitive tasks for example, transplanting, potting or preparing cuttings. A permanent set-up may include the media preparation, container filling equipment and workstations or a transplanting conveyor. Having all materials and workers in one area reduces materials movement and makes supervision easier. Generally a central transplanting area is more efficient if the greenhouses are connected to a central headhouse. Experimentation will indicate that level. ![]() This requires proper moisture content that varies with the type of growing mix used. Transplanting is easier if good dibble holes have been formed in the growing medium surface of the flat.Doing this many times a day adds to the cost of the plants and tires workers. A 10 foot round trip to pick up a flat costs about 2 cents. Reduce the amount of walking that the transplanters must do.Locate flats as close as possible to employees’ work stations.Time spent walking, reaching or looking for materials adds costs. One key to efficient transplanting is to have materials and seedlings handy. The potting bench is moved from one end of the greenhouse to the other as the space is filled. Seedlings are transplanted into the flats which are then placed directly onto the growing space on the floor. To save labor and time, prefilled flats or pots can be brought in stacked on pallets.įor greenhouses where the flats are grown on the floor, movable potting benches on wheels work best. Seedlings and flats are supplied to each greenhouse as needed. Transplanting can be done either in the greenhouse where the plants are to be grown or in a separate area usually a headhouse.įor the small grower with separate freestanding greenhouses, it is usually most convenient to work right in the greenhouse. Every effort should be made to make it as efficient as possible. Transplanting is a large labor user in greenhouses and nurseries.
