剌槐生长迅速,用途广泛,适应性强,是我省重要的造林树种。原产地在美国东部的阿拉契亚山脉和奥萨克山脉一带,是典型的温带树种,所以喜光性很强,不耐庇阴,特别是杂草的危害,严重地影响着树木的生长.如果造林后的几年内,不进行幼林的抚育管理,剌槐很难迅速成材或长成“小老树”,因此进行剌槐的幼林抚育是非常必要的。1987年我们在元氏县良桑场进行了剌槐幼林的松土除草,修枝抚育试验,现将试验结果整理如下.
Slash Huai rapid growth, wide range of uses, adaptability, is an important afforestation species in our province. Origin of the United States in the eastern part of the Aramaya Mountains and the Osama Mountains, is a typical temperate tree species, so happy like a strong light, insensitive to shade, especially weeds hazards, seriously affecting the growth of trees. Within a few years after afforestation, it is very difficult for acacia to grow up or grow into “little old trees” without tending and management of young forests. Therefore, it is necessary to nurture young plants in acacia. In 1987, we conducted a weeding and trimming test of young acacia grass in young mulberry field of Yuanshi County. The test results are summarized as follows.
