Therefore, how to strengthen management so that the early results of these saplings, early high-yielding fruit trees in our province is an urgent solution to the problem. From 1976 to 1977, on the basis of a comprehensive understanding of the management of young saplings in the key fruit producing areas in our province, we conducted a survey and research on sapling and trimming techniques of saplings.
