MECHANIZATION IN THE ROOTING OF CUTTINGS: 1906 to 1966
William E. Snyder
The plant propagator is apt to take for granted many techniques of mechanization which were unknown to his predecessor sixty years ago. Continued mechanization in the propagation of plants is a necessity in today's competitive production of plants. Reduced labor costs, elimination of "human error" in judgment and accurate control of the environment of the cutting will more than pay for the costs of mechanization. Therefore, for a few moments, let us take a brief look at past and present methods of regulating the environment. I have chosen to compare today's equipment with those described in the 10th edition of L. H. Bailey's "THE NURSERY BOOK—A Complete Guide to the Multiplication of Plants", published in 1906 (1).
First, we shall compare the aspects of the environment—atmospheric and soil—considered of importance sixty years ago and today. Second, we shall take a brief look at some of the structures used to regulate these environmental factors, then and now. Finally, we shall examine
