Seed planting methods and matters needing attention of Pteris angustifolia

The seeds can be sown in spring and autumn, and the potted soil needs to be disinfected before planting, and then one seed can be put into the pot. The suitable temperature for growth is 15-20 ℃. In the bud stage, it can be cultured in a cool and ventilated place, bathed in appropriate light, and sufficient sunlight should be given during the growth period. Water can be watered once a day in the seedling stage, and the amount of water can be reduced according to the temperature in the growth and flowering stage. when the branches and leaves grow too dense, they should be pruned in time to actively do a good job in the prevention and control of diseases and insect pests.

I. soil sterilization

One seed can burst into the basin. Before planting, the planting soil needs to be disinfected, then the soft soil is put into the fresh-keeping bag, and after a small amount of water is added, it is put into the microwave oven for sterilization, or the soil is fried in a pot to be sterilized at high temperature.

Second, seed sowing

Before sowing, you need to wet the treated soil with water, wait until the soil is drenched, and the soil at the bottom of the basin will not drip, then put the seed on white paper, sow it evenly with a toothpick, and then cover the top of the seed with the prepared soft soil.

Third, seed germination

Then accelerate the germination of the seeds, in order to promote the rapid growth of the stars, you can cover the flowerpot with a layer of plastic film to keep the seeds moisturizing and insulating, and at the same time, you need to put a few small holes in the film, which is beneficial to the breathability of the seeds and prevent the seeds from being suffocated.

IV. Post-budding management

Generally wait for 5-7 days, the seeds will germinate, after germination, put the bud flowerpot in a cool and ventilated place for breeding, and then bathe in appropriate light, which is conducive to promoting its growth and development.

5. Suitable temperature

Artemisia mandshurica is a plant that is very afraid of heat, and the suitable temperature during growth is 15-20 ℃, so you can choose to sow in spring, and the south can choose to sow in spring and autumn. When the temperature exceeds 30 ℃, it will cause deformed flowers to grow, and when the temperature is lower than 10 ℃, it will cause plant clustering or dormancy.

VI. Moisture control

The water demand of Mantianxing is mainly divided into two stages, and the demand for water is higher in the seedling stage, so it needs to be watered once a day, but in the growth and flowering stage, the amount of water needs to be reduced, usually once every 7 days in spring and autumn, once every 2 days when the temperature is high in summer and once every 10 days when the temperature is low in winter.

7. Adequate light

The full sky star is a positive plant, which needs to be given sufficient light during breeding to promote its growth and development. In summer, it can be illuminated all day, generally bathing in the sun for more than 8 hours, but we should pay attention to avoid exposure. Half-day sunshine can be carried out in winter, and if the light of the day is relatively weak, it can be maintained to make up the light and make the stars have sufficient light and beautiful flowers.

8. Pruning in time

The full star grows more vigorously, so it needs to be pruned in time, which is conducive to its branches and leaves growing more beautiful. when the branches and leaves grow too dense, you can choose to cut off the faster-growing branches and longer-growing branches. make the potted plant full of stars more ornamental.

9. Disease prevention and control of Mantianxing

Leaf spot disease: you can choose to spray 65tic100 Dyson zinc wettable powder 600 times, spray 2-3 times.

Root rot: you can choose to irrigate the root with 800 times of the root rot liquid, and pay attention to avoid stagnant water in the basin at the same time.

Ten. Pest control all over the sky

Aphids: you can choose to spray with neutral washing powder with water, or spray diluted essential oils.

Snail: you can choose to spray Miaoling granule for control.
