Problems solved by technology

[0004] However, after searching, it is found that there is currently no method for rapid propagation of tamarix in summer
The main reasons are as follows: 1. Most of the branches in summer are not fully lignified branches; 2. The temperature is very high, and it is very easy to appear wilted seedlings; 3. The ground temperature is high, and the roots are prone to rot

Embodiment 1

[0028] A kind of tamarisk seedling summer rapid propagation method, comprises the steps:

[0029] Step 1. Select the incompletely lignified Tamarix branches of the year and cut them into cuttings. In this step, the length of the cutting strips is trimmed to 5 cm, and one leaf is reserved; the roots of the cutting strips are soaked in a solution of rooting powder with a concentration of 200 ppm for 2 minutes.

[0030] Step 2. Insert the cuttings into a nutrient bowl filled with sand and place them in a greenhouse nursery equipped with a sunshade net. In this step, the sandy soil is a mixture of fine sand and ordinary soil, wherein the weight ratio of fine sand and ordinary soil is 2.5:1, and the ordinary soil is the soil in the greenhouse nursery; the cutting depth of the cutting strips is 3 / 4 of the length of the cutting strips ; The placement density of the cuttings is 80 trees / square meter.

[0031] Step 3. Water the cuttings to keep the leaves moist. In this step, spray ...

Embodiment 2

[0034] A kind of tamarisk seedling summer rapid propagation method, comprises the steps:

[0035] Step 1. Select the incompletely lignified Tamarix branches of the year, keep 2 leaves, and trim them into cuttings with a length of 7cm. Before the cuttings are cut, the roots are first soaked in a rooting powder solution for 3 minutes. Commercially available No. ABT6 rooting powder, solution concentration is 254ppm.

[0036] Step 2. Prepare sandy soil. The weight ratio of fine sand and ordinary soil in the sandy soil is selected as 2:1. The ordinary soil is saline-alkali soil in the greenhouse nursery; put the sandy soil into the nutrient bowl, and then insert the cuttings into the sandy soil In the nutrient bowl, the depth of cuttings is 2 / 3 of the length of the cuttings; finally, the cuttings are placed in the greenhouse nursery at a density of 90 trees / square meter. The greenhouse nursery is equipped with sunshade nets, ventilation systems and spraying devices.

Embodiment 3

[0040] A kind of tamarisk seedling summer rapid propagation method, comprises the steps:

[0041] Step 1. Select the incompletely lignified Tamarix branches of the year and cut them into cuttings. In this step, the length of the cutting strips is trimmed to 8 cm, and 2 leaves are reserved; the roots of the cutting strips are soaked in BT6 rooting powder solution with a concentration of 300 ppm for 2 minutes.

[0042] Step 2. Insert the cuttings into a nutrient bowl filled with sand and place them in a greenhouse nursery equipped with a sunshade net. In this step, the sandy soil is a mixture of fine sand and ordinary soil, wherein the weight ratio of fine sand and ordinary soil is 1.5:1, and the ordinary soil is the soil in the greenhouse nursery; the cutting depth of the cutting strips is 2 / 3 of the length of the cutting strips ; The placement density of the cuttings is 100 trees / square meter.

Abstract

The invention relates to a rapid propagating method of Chinese tamarisk seedlings in summer, which comprises the following steps: (1) selecting Chinese tamarisk branches which are not completely lignified in the year, and scissoring into cuttage branches; (2) cutting the cuttage branches into a nutrition pot holding sand soil, and placing in a greenhouse nursery, wherein the temperature inside the greenhouse nursery is 20-30 DEG C; (3) carrying out water spraying treatment on the cuttage branches to keep the leaf surface wet; and (4) domesticating the seedlings 10-20 d before the seedlings leave the nursery to obtain the Chinese tamarisk seedlings. By adopting the method provided by the invention, rapid propagation of Chinese tamarisk seedlings from June to September can be realized, and the Chinese tamarisk branches which are not completely lignified are used as cuttage branches, so that the survival rate is high and the propagation rate is high.

Description

technical field [0001] The invention relates to the technical field of tamarisk cultivation, in particular to a rapid propagation method for tamarisk seedlings used in summer. Background technique [0002] Tamarix is ​​a shrub or small tree, 3-6m high. Young branches are weak, spreading and drooping, reddish purple or dark purple. Leaves scale-like, subulate or ovate-lanceolate, 1-3mm long, semi-adnate, with keel-like columns on the back. Flowering 2-3 times a day; In spring, lateral racemes are formed on the nodes of last year's young branches, and the flowers are slightly larger and sparse; In summer and autumn, racemes are formed on the tops of current year's young branches to form terminal large panicles, often curved downward, Flowers are slightly small and dense, each flower has 1 linear subulate green bracteole; 5 flowers, pink; sepals ovate; petals elliptic obovate, about 2mm long; stamens are inserted between the disc lobes, Longer than petals; ovary conical urce...
