Trellis system

Moisture trapped in a dense canopy will create an ideal environment for mildew and rot. The trellis system used by Fetzer aims to keep the fruit and canopy away from each other. They use a vertical trellis, bilateral cordon trained, with spur pruning, the canes being grown vertically (Fig. 11.3). They then have what they call a fruit zone with a canopy of leaves overhead. This canopy is thinned by hand at various times during the growing season to provide aeration and allow sunlight onto the grapes. 

Unlike summer raspberries, autumn raspberries fruit on current-year canes. The trellis system is the simplest training system.

In order to maximize service area, the terrestrial broadcast mode incorporates trellis coding, with added precoding that allows the data to be decoded after passing through a receiver comb filter, used selectively to suppress analog co-channel interference. The high-data-rate mode is designed to work in a cable environment, which is less severe than that of the terrestrial system. It is transmitted in the form...
