建立杉木嫁接种子园是实现杉木良种化的重要途径。但是,在建园过程中,常常遇到嫁接好的植株长到2-5米高时,因大风、雪压或牲畜的危害,在接位处被折断。为了使种子园尽早建成,1983年3-4月上旬,我们探索出了大砧(基部)劈接法,扭转了过去重新补砧或培育萌芽条再嫁接的繁琐做法,解决了生产中的实际问题。现将方法介绍如下:
The establishment of fir grafting seed orchard is an important way to achieve the seed of Chinese fir. However, during the construction of the park, it is often encountered that grafted plants grow to 2-5 meters in height and are severed at the junction due to the gale, the snow pressure or the livestock. In order to make the Seed Garden completed as early as possible, in early March-April 1983, we explored the method of cleaving the large anvil (base), reversing the cumbersome practices of re-grafting or sprouting in the past and then grafting to solve the problem of actual production problem. The method is introduced as follows:
