LIGHT IS ESSENTIAL FORSOLID ALMOND YIELDS

摘要

Heavily shaded canopies can cause spur mortality and take a bite out of your orchard's productivity.FINDINGS FROM A six-year study conducted by University of California, Davis researchers reveal that light interception is the deciding factor in how many almonds a given tree will produce."The complete study (conducted between 1995 and 1998, and again between 2001 and 2006) documents the life cycle of spurs in almond trees," Theodore Dejong, one of the research team members, says. "Individual spurs rarely produce fruit in two subsequent years, and their productivity decides the actual crop. We found that spurs have to be in the light to bear fruit. Heavy shading in a canopy can lead to a greater proportion of the spurs dying."
