Problems solved by technology

[0003] At present, the seedling raising techniques about phlox are mainly sexual reproduction and asexual reproduction, wherein asexual reproduction mainly includes techniques such as branching and layering, and for sexual reproduction, that is, the technology of seed seedling breeding and reproduction, there are also reports in the prior art, but now There is a low survival rate for phlox seedlings with a single technology

Embodiment 1

[0014] A method for improving the survival rate of phlox seed seedlings, the method comprises the following steps:

[0015] (1) Seed collection: After the fruit is harvested, wash it several times with water and filter it to remove the sundries and obtain pure seeds. Spread the seeds and dry them in the shade at room temperature;

[0016] (2) Preparation of plant extract: select a well-developed Senecio plant, collect its roots, stems, and leaves, dry them in the shade, cut them into pieces with scissors, weigh 5, 2.5, and 10 g of the roots, stems, and leaves, and add 100 times distilled water , soaked at 25°C for 48 hours, filtered through 4 layers of gauze to obtain the original solution of the extract, and then evaporated under reduced pressure with a rotary evaporator to obtain a concentrated solution, and set the volume to 100ml; add 20ppm gibberellin and 15ppm salicylic acid to the above to obtain the extract liquid;

[0017] Pretreatment before sowing: before sowing, s...

Abstract

The invention discloses a method for increasing the seedling culture survival rate of phlox drummondii seeds. The method mainly comprises the following steps: acquiring the seeds and pre-treating the seeds. According to the method, a growth regulator and the technology of breaking through seed dormancy by reasonably utilizing light and the like are comprehensively utilized; especially after the phlox drummondii seeds are soaked with groundsel extract liquid, the growth regulator and salicylic acid, the germination survival rate of the phlox drummondii seeds is greatly increased; the phlox drummondii seeds obtained through the method are strong in seedling root system, good in growth state and high in speed and survival rate.

Description

technical field [0001] The invention relates to a method for improving the survival rate of phlox seedlings. Background technique [0002] Phlox, an annual herb, is not cold-resistant, likes warmth and avoids extreme heat. The flowering period is long, and the seeds reproduce. The soil should not be too thick when sowing, and it is better to be slightly transparent. The optimum temperature for germination is 15-20°C. Phlox has bright colors, dense flowers, long flowering period, and extensive management. Therefore, it is the main variety of basic flower beds, and the effect of potted plants is also very good. The height of the plant is 15-30cm, the color is mixed, the growth period is 4-6 months, the flower color is various, suitable for potted plants and flower beds. [0003] At present, the seedling raising techniques about phlox are mainly sexual reproduction and asexual reproduction, wherein asexual reproduction mainly includes techniques such as branching and layering...
