Description
Technical Field
The invention belongs to the technical field of vegetative propagation of plants, and particularly relates to a method for rapidly rooting sympodial bamboo branches and application thereof.
Background
The sympodial bamboos are not easy to seed after blooming and cannot be propagated sexually. Vegetative propagation is a common method, with shoot cutting being the most common method of propagation. Other methods of propagation are more difficult to apply. For example, a large amount of strong bamboo stalks are needed for stalk burying, joint burying, stump burying and the like, and the damage to bamboo forests caused by bamboo stalk collection, bamboo stump seedling raising or afforestation is large. Moreover, at present, no enough bamboo forest area is available for collecting bamboo stalks and bamboo stumps, so that the methods are not beneficial to large-scale seedling culture; the tissue culture method is still immature in technology, is limited by weak outdoor stress resistance of seedlings and the like, and cannot be popularized and applied in production, so that the method for cutting the main branches and the secondary branches is mostly adopted for raising the seedlings of the sympodial bamboos.
In the process of branch cuttage, the branches are in false survival, namely, most branches are subjected to branch drawing and leaf spreading at the early stage of the cuttage, and the twigs continuously wither and die after 15 days. The key influencing the survival rate of the cuttage of the branches is whether the branches can rapidly take root, and the roots of the bamboo branches are expected to survive before the nutrients carried by the bamboo branches are consumed, so that the roots are not gradually withered.

The invention is realized by the following steps:
a method for rapidly rooting sympodial bamboo branches comprises the procedures of branch selection, branch collection, water temperature control, air filling and oxygen charging, branch management and the like, and specifically comprises the following steps:

(4) filling air and oxygenating: inserting an inflation pipe into the cultivation barrel for soaking the branch and stump, and filling air into the clear water soaking solution after electrifying;
(5) and (3) cutting management: cutting indoors to avoid direct sunlight, maintaining the temperature of clear water soaking solution at 20-26 deg.C and water depth of 10-12cm, and maintaining aeration, and changing water 1 time every 3-4 days.
Preferably, the selection time of the branches is 1-2 months per year.
Preferably, more than 2-year-old sympodial bamboos without diseases and insect pests are selected, and then 1-year-old main branches or secondary branches are selected from the sympodial bamboos, the branches of the main branches or the secondary branches are bright green, slightly powdery, full in branch stumps, and the bamboo sheaths of the stump parts are not rotted.
Preferably, the branches and roots of the branches collected in the step (2) are not cracked, and the bud of the branch and root is not damaged.
Preferably, the placement mode of the branches in the step (3) is vertical placement or inclined placement.
Preferably, the pretreatment in the step (3) is to soak the stump part of the branch with a rooting powder aqueous solution with the concentration of 50-100 mg/L.
Preferably, the temperature of the constant temperature clear water in the step (3) is 22 ℃.

(2) branch collection: cutting off a joint of a mother bamboo stalk and a main branch stump to obtain a main branch, cutting off a joint of the main branch stump and a secondary branch stump to obtain a secondary branch, cutting off tips of the main branch and the secondary branch to leave 2-3 branches with stumps, the length of the branches is 50-55cm, leaves are not left, branch sheaths of the branch stump part are peeled off after collection, and shading and moisturizing are carried out;
(3) controlling water temperature: pretreating the stump part of the branch with the branch sheaths, and then placing the branch stump part in clean water at the constant temperature of 20-26 ℃, wherein the distance between the stump part of the branch and the water surface is 10-12 cm;
(4) filling air and oxygenating: filling air into the clean water in the step (3);
(5) and (3) cutting management: avoiding direct irradiation of sunlight, keeping the temperature of clear water at 20-26 ℃, keeping continuously filling air, and changing water 1 time every 3-4 days.
2. The method according to claim 1, wherein said shoots in step (1) are selected from 1-2 months.
3. The method according to claim 1, wherein the sympodial bamboos in step (1) are grown for more than 2 years and have no plant diseases and insect pests.
4. The method according to claim 1, wherein the shoot stump of the shoot harvested in step (2) is not cracked and the stump bud is not damaged.
5. The method according to claim 1, wherein the placement of the branches in step (3) is vertical or diagonal.
6. The method for rapid rooting of clump bamboo shoots according to claim 1, wherein the pretreatment in step (3) is to soak the root parts of the shoots with an aqueous solution of rooting powder with a concentration of 50-100mg/L for 2-3 h.
7. The method for rapid rooting of sympodial bamboo shoots according to claim 1, wherein the temperature of the constant temperature water in step (3) is 22 ℃.
