Problems solved by technology

[0003] The breeding methods of mulberry tree mainly include sowing, cutting and tissue culture. Seeding belongs to sexual reproduction, the genetic stability is not high, and it is prone to variation, so the utilization rate is not high. Cutting and tissue culture belong to asexual reproduction, and the genetic stability is higher. At present, there is no set of reasonable and effective procedures for the treatment of cutting seedlings and later management of mulberry trees. Most of the straw is crushed to make a substrate, and then the seedlings are inserted. The survival rate of cutting seedlings is only in the range of 50-80%, so how to improve the survival rate of cutting seedlings is the direction of future development of mulberry planting

Embodiment 1

[0020] A seedling raising method for saplings, comprising the following steps:

[0021] Step 1, selection of cutting branches: select lignified branches on the 1-year-old, robust growth and no pests and diseases mother tree as cutting seedlings, the stem nodes of the cutting seedlings are 5 and keep 2 and a half leaves;

[0022] Step 2, configuring the seedling raising substrate: prepare the following raw materials in parts by weight: 10 parts of river sand, 5 parts of straw, 3 parts of plant ash, 3 parts of chicken manure and 5 parts of willow bark juice, and mix the above raw materials evenly to obtain the seedling raising substrate;

[0023] Step 3. Cutting: Trim the bottom of the selected cutting seedlings on an inclined plane, and bury the two stem nodes of the cutting seedlings in the seedling-raising matrix, and then pour water for setting roots. The water for setting roots is: indole Prepared by mixing 3 parts of acetic acid, 1 part of sodium nitrophenolate, 1 part of ...

Embodiment 2

[0027] A seedling raising method for saplings, comprising the following steps:

[0028] Step 1, selection of cutting branches: select the lignified branches on the mother tree of 2-year-old, robust growth and no damage by diseases and insect pests as cutting seedlings, the stem nodes of cutting seedlings are 5 and keep 2.5 half leaves;

[0029] Step 2, configuring the seedling raising substrate: prepare the following raw materials in parts by weight: 12 parts of river sand, 6.5 parts of straw, 5 parts of plant ash, 3.5 parts of chicken manure and 6.5 parts of willow bark juice, and mix the above raw materials evenly to obtain the seedling raising substrate;

[0030] Step 3. Cutting: Trim the bottom of the selected cutting seedlings on an inclined plane, and bury the three stem nodes of the cutting seedlings in the seedling-raising substrate, and then pour water for fixed roots. The water for fixed roots is: indole Prepared by uniformly mixing 3.5 parts of acetic acid, 1.5 part...

Embodiment 3

[0034] A seedling raising method for saplings, comprising the following steps:

[0035] Step 1. Selection of cutting branches: select 3-year-old, vigorously growing lignified branches on the mother tree of the sycamore tree without diseases and insect pests as cutting seedlings, the stem nodes of the cutting seedlings are 5 and retain 2 to 3 half leaves;

[0036] Step 2. Configure the seedling-raising substrate: prepare the following raw materials in parts by weight: 13 parts of river sand, 8 parts of straw, 3-6 parts of plant ash, 4 parts of chicken manure and 8 parts of willow bark juice. Mix the above materials evenly to obtain the seedling-raising substrate ;

[0037] Step 3. Cutting: Trim the bottom of the selected cutting seedlings on an inclined plane, and embed the four stem nodes of the cutting seedlings in the seedling-raising matrix, and then pour water for setting roots. The water for setting roots is: indole Prepared by uniformly mixing 4 parts of acetic acid, 2 ...

Abstract

The invention discloses a paper mulberry sapling raising method in the technical field of agricultural planting. The paper mulberry sapling raising method comprises the steps that 1, cottage branchesare selected, wherein lignified branches of healthily growing and disease and pest free seed paper mulberries of 1-3 years old are selected as cutting seedlings, the stem nodes of each cutting seedling is 5, and 2-3 half leaves are retained; 2, a seedling raising medium is prepared from, by weight, the following raw materials: 10-13 parts of river sand, 5-8 parts of straw, 3-6 parts of plant ash,3-4 parts of chicken manure and 5-8 parts of willow bark liquid, and the raw materials are evenly mixed, and after the seedling raising medium is obtained; 3, cuttage is performed, wherein slope pruning is conducted on the bottom ends of the selected cutting seedlings, 2-4 stem nodes are of each cutting seedling are embedded into the seedling raising medium, then normal roots are watered; 4, management is performed until new buds grow from the cutting seedlings; 5, seedling hardening and cultivation are performed, wherein the cutting seedlings are transplanted to the seedling raising medium after new buds grow from the cutting seedlings for 5-10 days, the humidity of the seedling raising medium is kept to 40-50%, and the temperature is kept to 25-27 DEG C. By adopting the scheme, the rooting rate and survival rate of cutting seedlings can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a seedling raising method for saplings. Background technique [0002] The mulberry tree (scientific name Broussonetia papyrifera), also known as Chu Tao, is a deciduous tree with a height of 10-20m; the bark is dark gray; the branchlets are densely pubescent. The crown is open, ovate to broadly ovate; the bark is smooth, light gray or taupe, not easy to crack, and the whole plant contains milk. It is a strong positive tree species with strong adaptability and strong stress resistance. The mulberry tree has the characteristics of fast growth, strong adaptability, wide distribution, easy reproduction, high heat, and short rotation period. Its root system is shallow, lateral roots are widely distributed, it grows fast, has strong germination and tillering ability, and is resistant to pruning. Strong anti-pollution. It is distributed in temperate and tro...
