Propagation of blueberries in compost amended media.

摘要

The objective of this study was to determine the effects of propagation media containing composted material on the rooting of hardwood and softwood blueberry cuttings. The physical properties were measured at the end of the experiment. The media used were pine bark fines, composted pine bark with ammoniated nitrogen added, hardwood bark and composted chicken manure, pine bark and cotton gin waste, and control (peat moss and perlite, 1:1). All treatments resulted in a low number of rooted hardwood cuttings compared to the control. The total number of roots per cutting and alive cuttings hardwood cuttings was increased by pine bark and ammoniated nitrogen compared to the remaining treatments. The control treatment resulted in the highest number of roots per softwood cutting. None of the treatments increased the number of roots of softwood cuttings and the number of alive cuttings was increased by all treatments compared to the control.
