摘要
通过选择立地条件基本一致的林地,采用不同坡位和施肥量进行马尾松幼林生长量对比试验。结果表明:坡位对马尾松幼林生长产生极显著影响,生长量大小依次为:下坡>中坡>上坡,其中下坡8年生马尾松的平均胸径、平均高分别为8.7cm、7.03m;施肥量多少对马尾松的生长量有影响,生长量大小依次为:施肥2次>施肥1次>无施肥,但由于在造林初期施肥,对其生长影响未达到显著差异。
Based on the selection of the basically the same forest land occupation conditions, the contrast experiment of the growth of Pinusmassoniana young forest was conductedby different slope positions and different amount of fertilization. The results showed that the slope position had a very significant effect on the growth of Pinusmassonianayoung forest, the order of growth amount of Pinusmassoniana was ： downhill 〉 midhill 〉 uphill. Of which, average DBH and average height of the eight - year - old Pinusmassonianaon the below slope were up to 8.7cm and 7.03 m. The amount of fertilization also had an effect on the growth amount of Pinusmassoniana, the order of growth amount of Pinusmassoniana was ： fertilization twice 〉 fertilization once 〉 no fertilization, but there were no obvious differences of the impact to the growth of the forest because of fertilization at the beginning of forestation.
