嫁接种子园是通过选择优良母树的枝条采用嫁接的方法建立起来的林木良种繁殖场。如何充分利用砧木和接穗的愈合力,则是提高嫁接苗成活生长,并关系到种子园早期结实的关键性问题。为此,我们在建园的过程中,对砧木的规格和培育方法,不同嫁接时期,不同嫁接部位和接穗的处理等进行了试验,有如下体会: 一、砧木的培育我们在春季采用三种方法培育砧木进行嫁接试验: 1、在苗圃地培育砧木:将圃地翻耕耙细施基肥后,做成底宽60厘米的大垅,栽1年生樟子松壮苗,株距30厘米;栽2年生壮苗。株距50厘米。在圃地培育1—2年后做
Grafted seed garden is through the selection of branches of fine trees using grafting methods established forest seed breeding. How to make full use of the healing power of rootstocks and scions, is to improve the survival of grafted seedlings, seed banks and the early maturity of the key issues. To this end, we in the process of building a garden, the rootstock specifications and cultivation methods, different grafting period, different grafting sites and scions of the treatment were tested, as follows: First, the stock of rootstock we use in the spring three Methods Rootstock grafting experiment: 1, nurture in the nursery to cultivate rootstocks: nursery land nursery fine base fertilizer, made at the end of 60 cm wide stamen, planted 1 year old Pinus sylvestris seedlings, plant spacing 30 cm; planted 2 years old and strong seedlings. Plant spacing 50 cm. Do nurture 1-2 years after nursery
