为了培育嫁接苗、建立种子园,生产大量优质种子供造林用,嫩江县高峰林场根据国外落叶松嫁接成功的经验,在1964年作了云杉、樟子松嫁接的试验。现简单介绍如下。嫁接方法一、组合:①云杉×云杉,②云杉×樟子松。二、材料:都是用的幼林砧木和50—60年生成熟林1—2年生嫩枝接穗。各组合砧木和接穗的情况如 In order to cultivate grafted seedlings, establish seed orchards and produce a large number of high-quality seeds for afforestation, according to the successful experience of grafting of larch in North China, the experiment of grafting of spruce and Pinus sylvestris var. Mongolica was carried out in 1964. Now brief introduction is as follows. Grafting methods First, the combination: ① spruce × spruce, ② spruce × Pinus sylvestris. Second, materials: are used young forest rootstocks and 50 - 60-year-old mature 1-2 year-old branches scion scion. Examples of combinations of rootstock and scion
