Mechanical systems for harvesting Orchideola bulbs in greenhouses.

Tissue-cultured Orchideola bulbs were grown in virus-free, net-protected greenhouses, in a substrate consisting of sand, peat, and foamed polystyrene particles. Two stages in the evolution of the bulbs production line, from manual operation towards full mechanization, are presented. A mobile structure with clod crushers, a vibrating screen, and a pneumatic separator for in-greenhouse harvesting was used in the first stage. The result was a substantial reduction of 65% in the labor associated directly with the harvesting operation. The whole production concept was changed in the second stage. Stationary growth tables were replaced with mobile plastic bins, which were transported at the end of the season to a stationary, large-scale harvesting system. This system separated the bulbs from the substrate, and sized them. The result was an additional reduction of 45% in work load related to harvest and postharvest operations, and improvement of the substrate mixing and sterilization operations.
