摘要
本文对红松幼苗进行不同施肥处理试验,调查苗高、地径,并测定根系生长指标,以作为筛选红松苗期最佳施肥量的依据。试验结果表明:以腐熟牛粪30 g+过磷酸钙1.5 g+尿素10g+硫酸钾22 g为基肥,并在次年追施过磷酸钙4 g+尿素22 g或过磷酸钙5.5 g+尿素17 g是最佳施肥方案。
In order to explore the effect of different fertilization treatments on the growth of 2-year-old Korean pine seedlings,the orthogonal experiment was used to carry out fertilization test on Korean pine seedlings,investigate the height and ground diameter of seedlings,and determine the root growth index,as the basis for selecting the best fertilization amount at seedling stage.The results showed that 30 g of rotten cattle manure+1.5 g of superphosphate+10 g of urea+22 g of potassium sulfate were the base fertilizer,and the best fertilization scheme was to apply 4 g of superphosphate+22 g of urea or 5.5 g of superphosphate+17 g of urea in the next year.
