Rooting tree cuttings... [gardening]

[Externet]

Hi.

Seen publications and also videos on rooting cuttings using 'natural' and chemical compounds; but it is always done to few inches of cuttings.

Anyone knows methods to promote rooting to a 5, 6, + feet long branch cutoff from a mature tree ?  Or a link to such ?  Ideally, for fruit trees, but, thinking also on timber harvest; respectable branches from downed trees are just left to rot.  It would be interesting to gain years of growth by planting large branches...

Adding to above, has something like this ever been attempted?  :

Unearthing a root portion from a stump of a recently downed tree and match it as well as possible to a same diametre branch of 3, 4, + inches with any sterile method, including double ended thread lag screws ? 😳

Or, drilling vertical holes at a stump by the cambium perimeter and insert 'discarded' branches tight into the holes.  As to use an extensive, live root system already in place that would otherwise be left to rot.

Like grafting but to the root?

[Externet]

Yes, grafting to a root,  but for large limbs and roots; or promoting rooting to large mature branches that could bear fruit in much less time. 

After a trunk is harvested as timber, the point is to put back to use/growth all that is left unwanted.  Is there any technologies achieving such ?
