一、砧木培育:砧木的好坏直接影响着嫁接苗木的生长发育,从而影响苗木的正常出圃、出圃率的高低和嫁接成活率。生长健壮的砧木嫁接后易形成愈合组织,成活率高。板栗砧木应尽量选农家土板栗种培养砧木。据试验,农家土板栗种培育的砧木,嫁接成活率可达90%以上,锥票砧木成活率仅为10%左右。同时,健壮板栗砧木比生长不良的板栗砧木成活率高20%左右。二、嫁接季节:就理论而言,从树体开始萌动时起,至树体停止活动时止,皆可嫁接。但各种树木的生长特性不同,不同时期的嫁接效果参差不齐。板栗苗嫁接一般以秋季为宜,约9月下旬至10中… 相似文献

正进行苗木嫁接,既可保持母本的优良特性,又可弥补苗木某些部位的缺陷、满足造型需要,还可大大缩短盆景的制作时间,因此被广泛采用。本文浅谈如何提高苗木嫁接成活率。选准嫁接季节嫁接季节因嫁接所用的接穗不同而异。枝接多在春季进行,一般以砧木树液开始流动时为最佳;芽接在整个苗木生长季节均可进行,以砧木皮层易剥离为最好。砧木和穗条的选择与处理选亲和力强的树种作砧木。砧木穗条的亲和力要强,这是嫁接成活的前提和基础。亲和力不 相似文献

Planting stock type and quality can have an important impact on early growth rates of plantations. The goal of this study was to evaluate early growth and root/shoot development of different planting materials in typical heavy clay soils of northwestern Quebec. Using one-year-old bareroot hybrid poplar dormant stock, four planting materials were compared: (1) regular bareroot stock, (2) rootstock (stem pruned before planting), (3) whips (roots pruned before planting), and (4) cuttings (30 cm stem sections taken from the basal portion of bareroot trees, i.e. roots and shoot pruned). Rooted stock types (bareroot and rootstock) produced, on average, 1.2 times larger trees than unrooted stock types (cuttings and whips). However, shoot-pruned stock types (rootstocks and cuttings) reached similar heights and basal diameters as unpruned stock types (bareroots and whips), during the first growing season. Shoot pruning reduced leaf carbon isotopic ratios, suggesting that unpruned stock types were water-stressed during the first growing season. The stress was most likely caused by early leaf development while root growth occurred later in the summer. We conclude that shoot pruning bareroot stock is a useful management option to reduce planting stress without compromising early growth rates of hybrid poplars. 相似文献

通过研究野皂荚嫁接皂荚的不同嫁接方法、不同砧木粗度对嫁接苗成活率和生长量的影响。结果表明,插皮接和劈接的成活率均达到82%以上,嫁接当年新梢停止生长后高长量达到2 m以上。但劈接法比较费时、费工,最佳的嫁接方法为插皮接。不同砧木粗度对嫁接成活率的影响不大,但砧木越粗接穗的生长量越大。因此,在野皂荚改嫁皂荚定株时,要尽可能保留地径较粗的野皂荚进行嫁接。 相似文献

With the increased availability of cell grown broadleaved plantingstock on the UK market there has been a need to evaluate itsplace in amenity and forestry planting. The results of threeexperiments using oak and beech seedlings grown in three typesof modular cell or as undercut bare-rooted stock are described.Plants were subjected to poor plant handling, planting outsidethe normal season, cold storage and different planting methods. The results demonstrate that, one season after outplanting,cell grown stock was more resistant to poor standards of planthandling, and being planted outside the normal planting season,compared with bare-rooted stock. On the other hand, there wereno significant differences between the stock types due to coldstorage or planting method. The difficulties of conducting trials between stock types arediscussed. The development of a Plant Quality Index which describesthe morphological and physiological features of good plantingstock, and the assessment of complete establishment systemsis advocated as a better approach. 相似文献
