For example: Germany primula can not soak seeds, easy to lose vitality after soaking seeds(wholesale nursery pots); the seeds of ranunculus are low temperature, the seedling temperature should be around 8 °C, it is difficult to emerge above 12 °C. Some seeds are hi-light(12cm plant pots), some are light, and only good seedlings can be bred under appropriate environmental conditions.

(cheap plastic 3 gallon trade pot wholesale price)The selection of the seedling container should be carried out by using a hard plastic seedling box with a length of 50 to 60 cm(plastic nursery pots), a width of 30 to 40 cm, a height of 8 to 10 cm, and a large number of small holes at the bottom. The size depends on the amount of seeding, and the height is not too high. The number of germination days is about 14~21 days.
If there are many soils, it will not be easy to dry for a long time; if there is less soil, the higher walls will affect the light. Drain holes should be made at the bottom of the well-prepared nursery box(12cm nursery pot), and must be soaked in water for 2 to 3 days before use. Soak the bubble, otherwise the box will be separated from the soil. If it is lower than 15 °C, it will take 1~3 months to germinate(cheap plastic 3 gallon trade pot wholesale price).
When it is too high, the matrix ratio will be fully decomposed and sieved by manure(3 gallon trade pot), humus, fine sand and garden soil, mixed in a ratio of 2:1:1:1, sieved with a sieve that can sieve the sorghum, and Sunlight is disinfected for one day; seeds such as petunia should be around 25 °C Germination under temperature, if soaked in the low temperature for 1 to 2 days, the seeds may rot, no seedlings.
Temperature control: The optimum temperature for seed germination is 18-24 °C, and it needs light.Seeding method Put the seeds and fine sand in a pot at a ratio of 1:1500 and mix well, then spread evenly on the fine soil, then gently press on the fine soil with a smooth wooden board(5 gal pot), do not compact, so that the seeds and fine The soil can be integrated.(cheap plastic 3 gallon trade pot wholesale price)
The water level should not exceed the surface of the soi(plastic nursery pots wholesale)l, and the water should be added with the immersion until it is saturated(cheap plastic 3 gallon trade pot wholesale price). Take the soaked seedling box out of the water, cover it with a glass plate to moisturize (do not use plastic film, because it is easy to drip water to hurt the seedlings), control the water slightly, and immediately move to an environment suitable for seed budding.
Depending on the variety, it will germinate in 4 to 5 days, and it will germinate in 7 to 10 days in slow. After the seeds are germinated, the glass plates are taken out(13cm plant pots), and after most of the emergence, they are moved to a place suitable for growth. Soaking seeds: and at the same time hinders gas exchange, soaking seeds with warm water at 35~40 °C for 12 hours can significantly increase the germination rate.
It is worth noting that when there are no more than 2 pieces of real leaves, never spray water from above(seedling trays). Lavender seeds have a long sleep period, the shell is hard and dense, the surface is waxy, it is not easy to absorb water and expand and crack, which makes the seed germination difficult(cheap plastic 3 gallon trade pot wholesale price). Seed treatment strategy: species: first rub with fine sand to make it slightly damaged(14cm plant pots).
Growth stimulating hormone treatment: gibberellin is a commonly used growth stimulating hormone(one gallon plant pots). It is treated with gibberellin 20~50mg/L for 2-3 hours, and the emergence rate is low, which can make seeds germination early and increase germination rate, and promote seedling growth. Promote flowering. If it is not treated with gibberellin, it will take one month to germinate(15cm plant pots).
