Embodiment 1

[0018] 1. Collection of cuttings

[0019] (1) In mid-March, cut off the annual branches of the 1-3 year old, robust growth, and no pests and diseases.

[0020] (2) Select a branch with a diameter of about 1cm, cut it to a length of 12-15cm, and leave 2-3 buds, trim the lower end to an oblique cut surface, and trim the upper end to a flat cut surface, with the upper and lower incisions 1.0cm away from the buds.

[0021] (3) Bind every 30 pruned cuttings into a bundle to form a cutting bundle, wherein the biological lower end of the cuttings in the cutting bundle is strictly separated from the upper end, that is, the lower end of all cuttings is located at one end of the cutting bundle, and the upper end of all cuttings is located at one end of the cutting bundle. The other end of the bundle of cuttings.

[0022] 2. Treatment of cuttings with plant growth regulators

[0023] Soak the biological lower end of the cuttings in the growth regulator α-NAA solution, soak for 1 min, ...

Embodiment 2

[0032] Except that IBA is used as the growth regulator in the plant growth regulator treatment process, and the concentration of IBA is 1.0 g / L, the others are the same as in Example 1.

[0033] Root primordia appeared after 15 days of cutting, a large number of roots took place after 25 days, and the root system developed after 45 days. The number of rooted cuttings / total number of cuttings) was 88%, and the transplanting survival rate (number of surviving seedlings / total number of seedlings) was 93%.

Embodiment 3

[0035] Except that the combination of α-NAA and IBA is used as the growth regulator during the plant growth regulator treatment, and the solution concentration is α-NAA 0.5g / L+IBA 0.5g / L, the rest are the same as in Example 1.

[0036] Root primordia appeared after 15 days of cutting, a large number of roots took place after 25 days, and the root system developed after 45 days. The number of rooted cuttings / the total number of cuttings) was 92%, and the transplanting survival rate (number of surviving seedlings / total number of seedlings) was 96%.

[0037] In the present invention, cuttings are carried out in mid-March (10-20 days) and transplanted in mid-May. The seedlings have a long growth cycle and can be cultivated into larger seedlings in the same year, with high market value.

[0038] The cuttage management method of the present invention is simple, the production cost is low, and the requirements for cutting facilities are low. The cuttages in the small arched shed in t...

Abstract

The invention provides a hard wood cutting propagation method for paper mulberries, and aims to solve the technical problems that the conventional hard wood cutting is low in rooting percentage and the twig cutting is high in cost. The method comprises the steps as follows: selecting and clipping hard wood cuttings of a paper mulberry; soaking the cuttings in a plant growth regulator for treatment; and hardening seedlings and transplanting the seedlings. According to the method, cuttings take many roots quickly, leaves expand much at the overground part and grow consistently, the cutting rooting percentage is higher than 88%, the cutting sprouting percentage is higher than 90%, and the survival rate of seedling transplanting is higher than 93%; and with the method, the reproduction speed can be increased, and seedling culture management is simple, convenient and low in cost.

Description

technical field [0001] The invention relates to the technical field of plant vegetative propagation, in particular to a cutting propagation method of hard branches of mulberry trees. Background technique [0002] Broussonetia papyrifera (L.) Vent is a deciduous tree belonging to the genus Broussonetia L'Her. ex Vent. of the family Moraceae. The mulberry tree is widely cultivated in my country, and it is also distributed in Japan, India, and the Pacific Islands abroad. [0003] Paper mulberry is not only resistant to drought, barrenness, saline-alkali, but also to dry, cold and humid climates. It can grow vigorously in acidic, neutral or calcareous soil, land with a salt content of less than 0.4%, and remote mountain wasteland. The mulberry tree has a better function of maintaining water and soil and preventing land desertification, and can be used as the main cultivated tree species for ecological protection projects. The mulberry tree also has a strong function of purifyi...
