在采用嫁接法繁殖的花木中,时有出现接穗粗、砧木细的“小脚”现象,既影响整体观赏价值,又易因头重脚轻被大风吹折。造成“小脚”现象的原因,有的是砧木选择不当,有的是接茬愈合不良,致砧穗生长不同步(如用同种树木实生苗作砧木,注意嫁接方法,可以避免)。对已发生小脚现象的花木,可根据栽培形式,采用下述方法进行技术改造。深埋法适于地植花木。将有小脚病的植株(图A-1),于晚秋或早春带土团起出(A-2),尽量不伤或少伤根系;如竖根过长,
Grafting in the use of flowers in the law, there are sometimes scion rough, thin rootstock “phenomenon”, not only affect the overall ornamental value, but also easy due to top-heavy wind blowing. Causes of “small feet” phenomenon, some rootstock improper choice, and some poor connection cupping, resulting in the rootstock growth is not synchronized (such as the same species of seedlings as rootstock, pay attention to the grafting method, can be avoided). On the phenomenon of small feet have occurred flowers, according to the cultivation form, the use of the following methods for technological transformation. Buried law suitable for planting flowers and trees. Plantlets with foot and foot disease (Figure A-1) will appear in the late autumn or early spring with soil (A-2), try not to hurt or damage the root system as much as possible; if the root is too long,
