Embodiment 1

[0020] A kind of stone fruit class economic forest rootstock hard branch cutting propagation method is: the first step, on December 10, pick the hard branch of the stone fruit class economic forest stock 'VIKEN' annual branches, put indoor shade and cool place, indoor temperature 5 ℃~10 ℃, air The relative humidity is 95%; the second step is to use pruning shears to cut the branches into cuttings, the thickness of the base of the cuttings is 0.5-1.0cm, and the length is 5-10cm. 40° oblique opening; soak the cut cuttings in 50 mg / kg potassium naphthalene acetate salt solution for 3000 seconds, the soaking depth is 1 / 3 of the length of the cuttings; the third step is to soak the cuttings in the In the coarse river sand slotting bed, the coarse river sand particle size is 0.2-0.5mm, the rough river sand thickness of the slotting bed is 15cm, and the moisture content of the coarse river sand is 20%. The cutting groove depth is 5cm, and the cuttings are 30° oblique to the horizontal...

Embodiment 2

[0022] A kind of stone fruit class economic forest rootstock hard branch cutting propagation method is: the first step, adopt the hard branch of stone fruit class economic forest stock 'NAPLEB' annual branch on February 1, put indoor shady and cool place to preserve, indoor temperature 10 ℃~15 ℃, The relative humidity of the air is 90%; the second step is to cut the branches into cuttings with pruning shears, the thickness of the base of the cuttings is 1.0-2.0cm, and the length is 10-15cm. ~70° oblique opening; quickly soak the cut cuttings with 1000mg / kg potassium naphthalene acetate aqueous solution for 10 seconds, and the soaking depth is 1 / 4 of the length of the cuttings; the third step is to soak the cuttings soaked in potassium naphthalene acetate The cuttings are placed in the coarse river sand bed, the particle size of the coarse river sand is 1.0-2.0mm, the thickness of the rough river sand in the bed is 30cm, and the moisture content of the coarse river sand is 10%. ...

Embodiment 3

[0024] A kind of stone fruit class economic forest rootstock hard branch cutting propagation method is: the first step, pick the hard branch of stone fruit class economic forest stock 'CRUT' annual branch on November 15th, put indoor shady and cool place to preserve, indoor temperature 10 ℃~15 ℃, The relative humidity of the air is 90%; the second step is to use pruning shears to cut the branches into cuttings, the thickness of the base of the cuttings is 1.0-2.0cm, and the length is 10-15cm. Among them, the upper notch is cut into a flat cut, and the lower notch is cut into a 40° ~70° oblique opening; quickly soak the cut cuttings with 500mg / kg potassium naphthalene acetate aqueous solution for 20 seconds, and the soaking depth is 1 / 3 of the length of the cuttings; the third step is to soak the cuttings soaked in potassium naphthalene acetate The cuttings are placed in the coarse river sand bed, the particle size of the coarse river sand is 1.0-2.0mm, the thickness of the roug...

Abstract

The invention provides a drupaceous economic forest rootstock hardwood cutting propagation method which comprises the steps as follows: a first step, annual winter hardwood tress of drupaceous rootstock introduced from America is stored in cool places in rooms from December 1 to March 1, the room temperature is 5 DEG C to 15 DEG C, and the relative air humidity is 90% to 100%; a second step, the tress is cut into cutting slips by a pruning shears, and the cut slips are soaked in naphthylacetate salt aqueous solution; a third step, the cutting slips which are soaked in the naphthylacetate salt aqueous solution are cut in a rough river sand cutting bed, and the cutting slips are heated and humidified after being cut; and a fourth step, when roots of the cutting slips grow to 1.5-5cm, the rooted cutting slips are excavated from the rough river sand and are moved into a nutrition pot filled with mixed substrate of turfy soil and field soil to be well watered and shaded by a shading net for 5 to 15 days. The implementation of the invention can keep the genotype and all good characteristics of original variety by 100 percent and ensure the consistency of the growth of grafted variety and the cutting survival rate more than 98 percent.

Description

Technical field: [0001] The invention relates to an asexual propagation technology of rootstocks of stone fruit economic forests, in particular to a hard branch cutting propagation method of rootstocks of stone fruit economic forests, which is suitable for rapid propagation of rootstocks of stone fruit economic forests. Background technique: [0002] Stone fruit economic forests mainly belong to Rosaceae and Rhamnaceae, etc., and asexual reproduction methods are often used to propagate seedlings in production. The main propagation methods of stone fruit economic forests include grafting propagation, cutting propagation, root tiller propagation and tissue culture. Among them, the grafting propagation technology has rapid reproduction, high survival rate, easy mastery and popularization of the technology, and early results. It is most widely used in the breeding of improved seedlings of stone fruit economic forests. When propagating grafted seedlings, different rootstocks hav...
