Problems solved by technology

However, the existing natural resources of Cyclocarya paliurus are few, and the seedling breeding technology has not yet made a fundamental breakthrough, which seriously restricts the development and utilization of Cyclocarya paliurus
The seeds of Cyclocarya paliurus have deep dormancy characteristics. After conventional sowing, it takes every other year or even two years to germinate, and the seedling rate is extremely low; it is a tree species that is extremely difficult to root, and the survival rate of cutting propagation is low; grafting and group breeding have not yet been successful

Embodiment 1

[0014] (1) In the first ten days of May 2013, select branches that have not yet fully lignified from a strong mother tree that is one to two years old, and cut the segments with two leaf buds as cuttings. The biological lower end of the cuttings is flat, and 2 to 3 leaves.

[0015] (2) Soak the lower end of the cuttings in the rooting agent solution for 30 minutes. rooting agent by - Naphthalene acetic acid, indole butyric acid and GGR rooting powder mixed configuration, wherein - The concentration of naphthalene acetic acid is 100 mg / L, the concentration of indolebutyric acid is 100 mg / L, and the concentration of GGR rooting powder is 300 mg / L;

[0016] (3) Insert the cuttings treated with the rooting agent into the soil matrix, and the cutting depth is 3-3.5cm. After cuttings, use 80%wt carbendazim at a dilution ratio of 1:1000, and spray until the upper leaves are completely wetted. The soil matrix is ​​a mixture of red loam and vermiculite, and its weight ratio is 6...

The soil matrix is ​​a mixture of red loam and vermiculite, and its weight ratio i...

Embodiment 3

[0026] (1) In mid-May 2014, select branches that have not yet fully lignified from a strong mother tree that is one to two years old, and cut the segment with two leaf buds as cuttings. The biological lower end of the cuttings is flat, and 2 to 3 leaves.

[0027] (2) Soak the lower end of the cuttings in the rooting agent solution for 25 minutes. rooting agent by - Naphthalene acetic acid, indole butyric acid and GGR rooting powder mixed configuration, wherein - The concentration of naphthalene acetic acid is 250 mg / L, the concentration of indolebutyric acid is 200 mg / L, and the concentration of GGR rooting powder is 350 mg / L;

[0028] (3) Insert the cuttings treated with the rooting agent into the soil matrix, and the cutting depth is 3-3.5cm. After cutting, dilute with 20%wt organocopper fungicide at a ratio of 1:1200, and spray until the upper leaves are completely wetted. The soil matrix is ​​a mixture of red loam and vermiculite, and its weight ratio is 6.5:1; the r...

Abstract

The invention relates to an asexual reproduction method of cutting-seeding raising cyclocarya paliurus branches to solve the seedling technical problem of cyclocarya paliurus and to efficiently cultivate clone feedings. The method includes the following steps, firstly choosing un-entirely lignification branches from robust cyclocarya paliurus plants and cutting sections with two leaf buds as cuttings, wherein the biology bottom of a cutting is flat and 2 to 3 leaves are left on the upper portion, secondly immersing the lower end of the cuttings in rooting solution for 20 to 100 minutes, thirdly inserting cuttings treated by rooting agent into soil matrix with a depth of 3 to 3.5 cm and spraying with 80% by wt carbendazim until the upper leaves completely wetted after cutting, and fourthly shedding the cut branches with black sunshade nets, sterilizing and moistening the cuttings by spraying carbendazim every two days at the first week and later moistening by spraying water every two days. The cutting-seedling raising method of cyclocarya paliurus branches is simple and practical in operation, short in seedling period and high in cutting rooting rate, and is suitable for large scale cutting seedling.

Description

technical field [0001] The invention relates to a method for growing seedlings by cuttings of Cyclocarya paliurus, belonging to the technical field of plant vegetative propagation. Background technique [0002] Cyclocarya papaya ( Cyclocarya paliurus (Batal) Iljinskaja) is a rare and protected plant unique to my country, mostly scattered in the southern mountainous areas at an altitude of 500-2500 meters, and has high protection and application value. Studies have shown that its leaves and bark have multiple functions such as lowering blood sugar and blood fat, anti-tumor and anti-aging, and are good natural health food and medicinal resources. At the same time, Cyclocarya paliurus is a good timber and ornamental greening tree species. However, the existing natural resources of Cyclocarya paliurus are few, and the seedling breeding technology has not yet made a fundamental breakthrough, which seriously restricts the development and utilization of Cyclocarya paliurus. The...
