Breeding method of snapdragon

The propagation methods of goldfish grass include sowing and cutting. To sow the seedling bed, the sandy loam with loose soil structure, low groundwater level, good drainage and rich organic matter should be selected, the seedling bed should be watered thoroughly, and the seeds should be mixed with fine sand at 1:4. Cuttings are carried out in the spring and autumn, punching holes while inserting cuttings, and spraying water sooner or later after compaction.

Seeding in seedbed

It is better to choose sandy loam soil with loose soil structure, low groundwater level, good drainage and rich organic matter in seedling bed. The seedbed requires fine and smooth soil. In order to prevent the occurrence of diseases and insect pests, the sown land was sunburned 2-3 times about 25 days before sowing, and carbofuran was used to disinfect the soil before sowing.

When sowing, pour the seedbed thoroughly, mix the seeds with fine sand at 1:4, spread them evenly on the seedbed, and cover with a thin layer of plant ash after sowing. Cover it with 50% shading net after watering, avoid sun exposure, and transplant 5-6 weeks after emergence.

Burrowing dish sowing

Disinfection of seeds and media is very important. The seeds were soaked in potassium permanganate solution with a concentration of about 0.5% for 1-2 hours before sowing. Add 150-200g methyl topiramate powder to each cubic meter of medium (about 20 bags), stir 2-3 times to make the drug fully mix with the medium, then spray water while stirring, adjust to the medium "hold into a ball, loose but not loose". Cover it with film for 8-10 hours and then pack it in the acupoint plate.

Each hole plate can sow 200 seeds and put one seed in each hole. After sowing, gently squeeze the seeds with the hand to make the seeds stick with the medium, and then spray water with a sprayer and cover with newspaper or plastic film. If the nursery can be dry, wet and temperature controlled, it does not need to be covered. Keep the newspaper moist for a long time and open it after the seeds germinate.

Cutting season

Cutting propagation can be carried out in both spring and autumn. Conditional greenhouse sunshine rooms can also be carried out in winter.

Cutting method

When cutting, a thin bamboo stick with a diameter of about 3 mm is used to punch holes in the substrate in advance, insert the cuttings while drilling, and gently compact the culture soil at the base of the cuttings with two fingers. After cutting, spray water on the basin soil and cuttings twice every morning and evening.
