摘 要:本文以一年生马尾松幼苗为研究对象,分析了不同配比施肥对马尾松幼苗生长的影响。结果表明:不同配比施肥对马尾松幼苗苗高、地径、生物量以及叶绿素含量具有不同的影响。处理12无论是苗高、地径、生物量、叶绿素含量均最高,所以处理12的N_(3)P_(4)K_(2)为最佳的施肥配比。建议马尾松幼苗N、P、K施肥浓度分别为8.25mmol/L、1.0 mmol/L、1.50mmol/L较为适宜。This article took annual Pinus massoniana seedlings as the research object and analyzes the effect of different fertilization ratios on the growth of Pinus massoniana seedlings.The results showed that different fertilization ratios had different effects on the seedling height,ground diameter,biomass,and chlorophyll content of Pinus massoniana seedlings.Treatment 12 has the highest seedling height,ground diameter,biomass,and chlorophyll content,so the optimal fertilization ratio is N_(3)P_(4)K_(2) for treatment 12.It is recommended that the fertilization concentrations of N,P,and K for Pinus massoniana seedlings be 8.25mmol/L,1.0mmol/L,and 1.50mmol/L,respectively.
