随着果树生产的发展,果树栽培制度也在迅速改革,由原来的乔砧稀植转向矮化密植。为了使果树矮化,可采用矮化砧嫁接。但是有些矮化砧根系生长过弱,冬季容易抽条,采用中间砧(即中间夹一段矮化砧)的办法,可能弥补以上的缺点。二重接是一种快速繁殖中间砧的方法。其具体操作技术如下: 以苹果嫁接为例,先培养山丁
With the development of the production of fruit trees, the fruit tree cultivation system is also rapidly reforming, from the original planting ancestral rare plants to dwarf and close planting. In order to dwarf the fruit trees, dwarf anvil grafting can be used. However, some dwarfing anvil root growth is too weak, easy to draw in winter, the use of the middle anvil (that is, a dwarfing folder in the middle of the way), may make up for the above shortcomings. Double docking is a rapid propagation of the anvil method. The specific operating techniques are as follows: Apple grafting, for example, the first cultivation of small mountain
