Embodiment 1

[0038] Embodiment 1 A kind of peony bud grafting propagation method

[0039] The method comprises the steps of:

[0040] (1) choose the rhizome that germinates a plurality of buds on the same rhizome, cut off the buds together with the roots of 3cm below it with a grafting knife, trim them to be inclined planes, cut longitudinally into tongues, and make scions;

[0041] (2) select the Radix Paeoniae Alba root that does not contain buds as the rootstock, cut out the corresponding inclined plane with the grafting knife on the upper end of the stock, and longitudinally cut it into a tongue shape on the inclined plane;

[0042] (3) Tightly insert the tongue-shaped scion in step (1) into the tongue-shaped incision of the rootstock in step (2) to ensure that the cambium on one side is aligned, use hemp rope to tighten the joint from bottom to top, and apply paraffin wax protection agent , Protect the interface from infection and dehydration.

Embodiment 2

[0045] Embodiment 2 A kind of peony bud grafting propagation method

[0046] The method comprises the steps of:

[0047] (1) choose the rhizome that sprouts a plurality of buds on the same rhizome, cut off the bud together with the root of 3.5cm below it with a grafting knife, trim it into a wedge-shaped inclined plane, and make a scion;

[0048] (2) select the peony root that does not contain buds as the rootstock, and the grafting knife cuts the upper end of the rootstock flatly, and then longitudinally cuts the middle part;

[0049] (3) Tightly insert the wedge-shaped scion in step (1) on the cut of the rootstock in step (2) to ensure that the cambium on one side is aligned, use hemp rope to tighten the joint from bottom to top, and apply paraffin protective agent to protect it. The interface is free from infection and dehydration.

[0050] The paraffin protective agent is prepared by adding naphthaleneacetic acid and carbendazim after melting paraffin; the addition amoun...

Embodiment 3

[0052] Embodiment 3 A kind of method for grafting and propagating Paeoniae officinalis buds

[0053] The method comprises the steps of:

[0054] (1) choose the rhizome that germinates a plurality of buds on the same rhizome, cut off the buds together with the root of 4cm below it with a grafting knife, trim it into a wedge-shaped inclined plane, and make a scion;

[0055](2) select the peony root that does not contain buds as the rootstock, and the grafting knife cuts the upper end of the rootstock flatly, and then longitudinally cuts the middle part;

[0056] (3) Tightly insert the wedge-shaped scion in step (1) on the cut of the rootstock in step (2) to ensure that the cambium on one side is aligned, use hemp rope to tighten the joint from bottom to top, and paste paraffin protective agent to protect it. The interface is free from infection and dehydration.

[0057] The paraffin protective agent is prepared by adding indole acetic acid and carbendazim after melting paraffi...

Abstract

The invention belongs to the technical field of plant cultivation, and in particular relates to a method for grafting and propagating peony buds. The method comprises the following steps: (1) selecting a rhizome with a plurality of buds on the same root, cutting off the buds together with the lower part of the root with a grafting knife, and pruning them as scions; The rootstock is cut with a grafting knife; (3) step (1) scion is combined with the step (2) rootstock, the joint is tightly wound from bottom to top with hemp rope, and the mud or paraffin protective agent prepared by sterilizing liquid is pasted , Protect the interface from infection and dehydration. The present invention proposes a grafting propagation technique in which the plump single buds of Paeoniae Alba are cut with part of the roots, and then grafted on the root tubers without buds after pruning. The present invention adopts the bud grafting propagation method to form one plant, which is different from the traditional method of ramets of Paeoniae Alba ( 2-4 buds are divided into one plant), compared with improving the reproductive efficiency of peony.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for grafting and propagating peony buds. Background technique [0002] Peony is a perennial herbaceous flower of the Paeoniaceae Paeoniae genus. It is a traditional garden ornamental plant and a new cut flower plant. Ornamental peony varieties are generally propagated by division due to the high rate of female and stamen petalization, loss or partial loss of fruitiness, and seed propagation cannot maintain ornamental properties. [0003] Peony, also belonging to the genus Paeoniaceae, is propagated by both ramets and grafting due to the lignification of the aboveground part. Peony grafting uses peony or peony roots as rootstocks, and peony branches as scions. Since peony is a herb, it is suitable for grafting when the current year's branches have withered during the breeding season, so no grafting is needed in production. Buds and fleshy roots ar...
