The invention relates to the technical field of
fruit tree propagation, in particular to a
pear, plum or apricot
germplasm resource nursery scion strip soil cuttage nursery building method in a cold and
arid region, which comprises the following steps: firstly, selecting an annual
branch, disinfecting, soaking in rooting
slurry containing
humic acid and a
growth regulator, digging a cubic soil lump at the root of a stock
plant, wrapping with non-
woven fabric, and covering the soil lump with soil; the method comprises the following steps:
cutting the scions with soil, injecting a water-retaining agent, spraying a
mixed solution of
potassium humate and
chitin, inoculating
mycorrhizal fungi at the same time, and finally digging planting holes according to a set planting spacing, arranging a
straw root protection cover, planting the scions with soil, thoroughly watering and burying a slow-release
fertilizer. According to the technology, through comprehensive treatment,
root system protection and rooting promotion, rapid and high-quality building of a resource garden under the severe condition of the cold and
arid region is ensured, and through the triple root protection and soil cuttage technology, the scion cuttage
survival rate of
germplasm resources of deciduous fruit trees such as pears, plums and apricots in the cold and
arid region is increased to 85% or above from traditional 60% or below.
