本文以配方施肥理论为指导,首次提出了以当地Ⅰ立地类型阔叶林砍伐后的第一代杉木人工林作目标产量的参比标准,结合杉木生态特性来计算杉木的需肥量。经进行试验表明,此种方法目标明确,定量准确,效果显著,是促进杉木速生丰产的有效途径。具有广阔的应用前景。 Guided by the theory of formula fertilization, this paper first proposed the reference standard of the first generation of Chinese fir plantation after cutting in the local I-site broad-leaved forest, and calculated the required fertilizer amount of Chinese fir with the ecological characteristics of Chinese fir. Experiments show that this method has clear objectives, accurate quantification, significant effect, is an effective way to promote fast Chinese fir yield. have a broad vision of application.
