摘要
针对樟子松的生理特性,采用正交设计的方法,共设计16种肥料配方对樟子松育苗施肥进行试验,结果表明,施肥处理对樟子松苗木的生长发育均有明显的作用,高生长提高6.5%～26.1%,径生长提高7.7%～30.8%,干质量提高19.2%～61.5%,N、K元素对高生长的作用达到极显著水平,N元素对径生长的作用达到极显著水平,N元素对提高干质量的作用达到极显著水平,K元素对提高干质量的作用达到显著水平。
According to the physiological characteristics of Pinus sylvestris var. mongolica, using orthogonal design method, a total of 16 kinds of fertilizer formulae were conducted experiments on Pinus sylvestris var. mongolica. Result shows that fertilization treatments all have significant role in the growth of seedlings. Height growth increase by 6.5%-26.1% ;diameter growth increase by 7.7% -30.8% ;dry quality improve 19.2% -61.5% ;N ＆ K elements reach the very significant level on the role of height growth ; N element reach very significant level on the role of diameter growth ; N elements reach a very significant level on the role of increasing dry mass;K elements reach a significant level on the role of increasing the dry mass.
