Embodiment 1

[0024] The rapid propagation process of Zhejiang Runnan includes the following steps:

[0025] Choose the nursery garden in Hangzhou area, the soil is deep and fertile, and the drainage is good. In the nursery garden, choose the robust 1-year-old Phoebe bournei seedlings as the grafting rootstock; the grafting time is March 5;

[0026] Choose the five-year-old Zhejiang Runnan with robust growth and no disease and insect pests, and cut out 100 branches with strong growth and full axillary buds on the outer periphery of the canopy. The upper ends of the branches are cut flat, the branches are removed, and the lower ends of the branches are cut into a 3cm-long wedge on both sides Bevel, keep a pair of axillary buds, control the length of the scion to 10cm, and then soak the lower end of the scion in the plant compound regulator, the soaking depth is 3cm, and the soaking time is 30min;

[0027] The formula of the plant compound regulator is: diethyl aminoethyl hexanoate 2 mg / L and α-naph...

Embodiment 2

[0031] The influence of different rootstock choices on graft survival rate.

[0032] Check the graft survival rate at two time points 30d and 90d after grafting, and judge whether the survival rate is based on green leaves and new shoots. See Table 1 for details.

[0033] Table 1

[0034] Rootstock 30d survival rate% 90d survival rate% Phoebe lanceolata6557 Yellow Heart Tree7164 Phoebe5450 Red Phoebe9594 Short-sequence Phoebe8174

[0035] From Table 1 above, it can be seen that choosing red phoebe as the rootstock has the highest survival rate, reaching more than 90%, and transplanting one-year-old grafted seedlings to northern Jiangsu can adapt to a colder climate with a survival rate of 100%. The planting range of forest trees is expanded, and it is more difficult to survive in northern Jiangsu by using other rootstocks.

Embodiment 3

[0037] The effect of antioxidant nutrients on graft survival rate and growth.

[0038] Group:

[0039] Group 1: Do not spray anti-oxidant nutrients;

[0040] Group 2: Sucrose is not added to antioxidant nutrients;

[0041] Group 3: Polyvinylpyrrolidone is not added to antioxidant nutrients;

[0042] Group 4: The antioxidant nutrient solution of the present invention.

[0043] See Table 2 for details.

[0044] Table 2

[0045] Group 90d survival rate% The average growth of surviving seedlings cm Group 17718.3 Group 28522.6 Group 38921.9 Group 4 9423.7

[0046] It can be seen from Table 2 above that compared with groups 1-3, group 4 uses polyvinylpyrrolidone and sucrose to combine to prepare an antioxidant nutrient, which can not only increase the graft survival rate, but also increase the growth of seedlings; among them, polyvinylpyrrolidone It can form a protective film on the surface of the callus, reduce the oxidation of the grafted part, and reduce the formation of harmful subs...

Abstract

The invention belongs to the technical field of forest propagation, and discloses a rapid expanding propagation technology for Machilus chekiangensis. The technology comprises the following steps of cutting off Machilus thunbergii stock trunks, truncating the trunks, adopting cleft grafting cutter for vertical cutting from the center of the cross section of the stock, taking out Machilus chekiangensis scions from a plant composite regulating agent and inserted into stock chopped opening to be aligned to a stock cut forming layer, then, an anti-oxidant nutrient agent is sprayed to the chopped opening, the opening is bound with a plastic rope, then, the opening is sleeved with a plastic preservative bag for sealing and moisture preserving to reduce water evaporation. The seedling growing speed can be increased, the new-variety high-quality seedlings can be rapidly obtained, the seedlings can adapt to the cold weather in the northern Suzhou, the forest planting range is enlarged, and the requirement of the market is met.

Description

Technical field [0001] The invention belongs to the technical field of forest tree breeding, and specifically relates to the rapid propagation process of Zhejiang Runnan. Background technique [0002] Zhejiang Runnan is a plant of the genus Lauraceae Runnan, a tree distributed in Guangdong, Guangxi, Hainan, Jiangxi, Hunan, Fujian and Zhejiang in China. It likes to grow in a warm and humid environment. It is more common in valleys or riversides. In particular, valleys, depressions, shady slopes and riverside terraces require a deep soil layer, high humus content, good drainage, loose and moist soil, and neutral or slightly acid loam or sandy loam rich in organic matter. Zhejiang Runnan has a good water conservation function; its branches and leaves contain aromatic oils and are used as medicine. It has the effects of reducing phlegm, relieving cough, reducing swelling, relieving pain, and stopping bleeding. It has the effects of treating bronchitis, burns and trauma and hemostatic...
