用嫁接的方法建立湿地松种子园,具有许多优点。但是,湿地松是从国外引进的,在种子园营造的嫁接过程中,如何解决当前接穗不足,仍是一个较大的问题。我们观察到湿地松萌发新梢的部位是多方面的,不但在主梢和侧枝的顶端能抽出新梢,而且在轮枝的腋间也可以抽出新梢。我们曾在1974年和1975年连续两年,将湿地松新抽的带皮侧梢,嫁接在马尾松砧木上,成活率高达83.3～88.9%,为增加接穗开辟了一条途径。 1974年嫁接成活的植株,其生长情况如表。 The establishment of wetland pine seed orchard with grafting has many advantages. However, Slash pine is introduced from abroad. In the process of grafting in the seed orchard, how to solve the shortage of current scion is still a big problem. We have observed that there are many aspects to the germination of the Pinus elliottii shoots, not only in the tips of the shoots and branches but also in the armpits of the shoots. We have been in 1974 and 1975 for two consecutive years, the loose-skinned mulberry pine shoots grafted on the masson pine rootstock survival rate as high as 83.3 ~ 88.9%, to open up a way to increase scion. Grafted alive plants in 1974, the growth of the table.
