但是网上看嫁接树容易出现砧木与接穗生长不一致,造成大小脚.会流传病毒,极易根癌
病.
愈合不牢固易风折等问题。
又看到一些视频说几棵树一个坑里和嫁接树是一个意思。
不然咱就买它几棵放一个坑里边？ 新手觉得嫁接树属于高难度，表示鸭梨很大 | i*******e

you kidding ? | y**l
发帖数: 1876 | 3 视频我找不到了，但是网上讨论这个的也很多啊。
比如这里： http://www.davewilson.com/homegrown/gardencompass/gc02_may_june_01.html
Plant three or four trees in the same hole or a multi-budded tree. Get the
most out of the space and materials. | u***l

很麻烦，也会出现一棵独大的情况。

If you have the space for one tree, you have the space for four trees. This
sounds like a lot, but when you prune for size control, you have so many
more options.
How many times during the year do you want to go to the store to buy fruit?
If the answer is "only when I have to!", planting in high density will help
you reach that goal.
Start by placing two, three or four trees into the same hole.
Plant the trees about 18 inches to 2 feet apart in the hole.
Plant three in a triangle pattern, four in a square.
When choosing the trees that will go into the hole, choose trees with like
spray requirements. This means trees for which standard sprays are done at
the same time.
For example, all apples need to be sprayed in the summer to protect from
codling moth.
You would not want to plant them with peaches that ripen at the same time
you need to spray.
The next rule has to do with summer pruning; to prevent the most vigorous
tree from dominating and shading out the others, cut it back in spring and
late summer so it cannot take over. Otherwise, summer pruning to shape and
control the size of four trees in one hole is the same as for single trees
covered above. Using this technique you can solve many problems of growing
fruit in the backyard, such as the space required for pollinator trees.
Plant the trees requiring a pollinator in the same hole, then add additional
varieties that seem interesting. If you want a peach, nectarine and apricot
but don’t have the room, add a plum and plant them in the same hole. | y**l
