以海岸松1年生苗为材料,研究了不同水分、氮肥供应水平对苗高、地径、茎干重和根干重的影响。结果表明,不同氮肥供应水平对4个指标的影响均达到显著性差异水平,不同水分处理对苗高、地径和茎干重的影响达到显著性差异水平,水肥互作对苗高、茎干重的影响达到显著性差异水平。 The annual growth of Pinus bungeana was used as material to study the effects of different water and nitrogen supply on seedling height, diameter, stem weight and root dry weight. The results showed that the effects of different nitrogen supply levels on the four indicators reached significant differences. The effects of different water treatments on seedling height, diameter and stem weight reached significant differences. The interaction of water and fertilizer on seedling height, stem weight The impact reached a significant level of difference.
