Problems solved by technology

Among them, some scholars have studied the development of Selaginella gametophytes, but because Selaginella plants are male gametophytes that grow in spores, the method of using gametophyte development to cultivate and reproduce has a long germination time, and the germination rate and seedling rate are very low.
However, Selaginella has higher requirements on the growth environment. If the cultivation method is not appropriate, the survival rate of Selaginella introduced and cultivated will be greatly reduced.
There are no relevant reports on the introduction and cultivation of Selaginella

specific Embodiment approach 1

[0032] Specific implementation mode one: the introduction and cultivation method of Selaginella chinensis in the northern region is completed by the following steps in the present implementation mode:

[0033] Step 1. Collection of transplanted plants: At the beginning of September every year in the northern region, select large and medium-sized Selaginella plants with individual large and medium-sized, bright green color, plant extension, and no incompleteness in the forest or rock crevices on the hillside for collection. Keep the underground parts of the plants and avoid damage, and at the same time collect the understory humus at the original collection site, and collect the Selaginella plants and place them in a cool and ventilated place;

[0034] Step 2, transplanting: within 3-5 days after collection, transplant the Selaginella plants with permanent soil into the potted culture medium, place them in the greenhouse, control the planting depth at 10-15cm, and water once on ...

specific Embodiment approach 2

[0038] Specific embodiment two: this embodiment is different from specific embodiment one: adopt humus, peat moss and fine sand combination to replace the culture medium described in step two, the volume ratio of humus, peat moss and fine sand is 10:2:1. Other steps and parameters are the same as in the first embodiment.

[0039] In step 3, the sunshine time in winter is less than 8 hours, and the 60w diffused light supplementary light is used to supplement the light so that the light time is 10 hours, and the light intensity is 170μmol·m -2 ·s -1 , The diffused fill light is set at a height of 2 meters above the plants, the shade net is removed when the light is filled, and the shade net is covered when the sun shines.

specific Embodiment approach 3

[0040] Specific embodiment three: the introduction and cultivation method of Selaginella chinensis is completed by following steps in the present embodiment:

[0041] Step 1. Collection of transplanted plants: it can be collected all year round in the southern region. Select large and medium-sized Selaginella plants with bright green color, stretched plants, and no incomplete individuals in the forest or rock crevices on the hillside for collection. Soil, keep the underground parts of the plants and avoid damage, and at the same time collect the leaf humus from the original collection place;

[0042] Step 2. Transplanting: within 7 days after collection, transplant the Selaginella plants with permanent soil into the culture medium, control the planting depth at 10-15cm, and the shading rate is 65%-75%. Water once on the day of planting ;

[0043] Step 3, management and cultivation after transplanting: the shading rate is controlled at 65%-75%, the cultivation temperature is c...

Abstract

The invention discloses an introduction and cultivation method of selaginella tamariscina, and belongs to the technical field of plant cultivation. The problems that existing wild selaginella tamariscina is low in introduction survival rate and improper in cultivation management are solved. The method comprises the steps that 1, large and middle stretching selaginella tamariscina plants with the bright green color and no residues are selected for collection from beginning of June to beginning of October each year in the northern area, and original soil and the underground portions of the plants are reserved and damage is avoided during collection; 2, the selaginella tamariscina plants with the original soil are transplanted into a potted culture medium within 3-5 d after collection is performed, the plants are placed at a greenhouse, the planting depth is controlled to be 10-15 cm, and thorough watering is performed one time on the planting day; 3, management and culture are performed after transplanting, wherein the shading rate is controlled to be 65-75%, the culture temperature is controlled to be 22-28 DEG C, the soil is kept wet slightly, and the moisture is controlled to be 70-80%. Collection can be performed all the year round in the southern area, and transplanting is performed within 7 days after collection is performed. The transplanting rate can reach 95% or above.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a method for introducing and cultivating plants, in particular to a method for introducing and cultivating Selaginella. Background technique [0002] Selaginella is a plant of the genus Selaginella in the family Selaginellaceae (Selaginellaceae), which is a group of small lycophyllous plants distributed worldwide, and is a perennial herbaceous fern. There are more than 700 species of Selaginella in the world, and 60-70 species in my country, including more than 20 medicinal plants. Selaginella tamariscana in this genus is named for its short plants and its branches and leaves are very similar to cypress trees. It is mainly born in dry rock crevices or hillsides, and the habitat at an altitude of 200-1000m, because it can still be used in extremely water-deficient environments. It survives for a long time, and once it meets water, it can quickly absorb water, and the plan...
