在株行距各为20英尺的李树园中,在每株树上或在四周的树上悬挂20克一小袋的人发,完全避免了鹿害。试验采用的是完全随机小区设计,四次重复。每一处理包括16株树,各处理之间有一行未处理的树相隔。在试验开始之前,整个12英亩的果园曾遭鹿严重啃害,果树在当时为二年生初的小苗。在其它一些林木果园的研究中也曾记载过类似 In tree-lined gardens of 20 feet each, hanging 20 grams of a pouch of hair on each tree or in the surrounding trees completely avoids deer damage. The experiment is completely random cell design, four repetitions. Each treatment included 16 trees separated by a row of untreated trees between treatments. Before the start of the experiment, the entire 12-acre orchard had been severely bored with deer, and the fruit trees were young seedlings at the time of the second year. Similar studies have been written in other tree orchards
