These tips can help you improve the germination rate of flower seeds.

In the process of flower cultivation, we often encounter such a problem: when sowing some flower seeds, little or no seedlings emerge. If you want to improve the emergence rate of flowers, Huahua provides you with a few tips, let's take a look!

1 understand the characteristics of seeds

Including the temperature, humidity, light, soil and so on needed for its germination, which is very critical. For example: Germany primrose can not soak seeds, after soaking seeds easy to lose vigor; buttercup seeds like low temperature, seedling temperature should be about 8 ℃, more than 12 ℃ is very difficult to emerge; petunia and other seeds should be at a temperature of about 25 ℃, if soaked in the low temperature for 1-2 days, the seeds may rot, do not emerge. Some seeds are light-loving, some are light-disgusted, and good seedlings can be produced only under suitable environmental conditions.

2 selection of seedling container

The seedling container should be a hard plastic nursery box with a length of 50 cm 60 cm, a width of 30 cm, a height of 8 cm and a lot of small holes at the bottom. Can be made with wood, the size depends on the amount of sowing, the height is not too high. When it is too high, if there is too much soil, it will not be easy to dry for a long time; if there is little soil, the high walls will affect the light. Make the bottom of the nursery box to hit the drainage hole, and be sure to soak in water for 2-3 days before use, until thoroughly, otherwise the box is easy to separate from the soil.

3 selection of matrix

In the matrix ratio, the fully mature barnyard manure, humus soil, fine sand and garden soil were mixed according to the ratio of 2 to 1, sifted with a sieve that could sieve sorghum, and sterilized by sun exposure for a day.

4 points for attention in sowing

The sowing method is to mix the seeds and fine sand in a basin in a ratio of 1RV 1500, then spread them evenly on the fine soil, and then gently press the seeds on the fine soil with a smooth plank, not compacting, so that the seeds can merge with the fine soil. Finally, soak the nursery box in water, the water level can not exceed the soil surface, soak with water until soaked. Take the soaked nursery box out of the water, cover it with a glass plate to moisturize (do not use plastic film, because it is easy to hurt seedlings by dripping), control the water slightly, and immediately move to an environment suitable for seed budding.

Depending on the variety, it will sprout in 4-5 days as soon as possible and 7-10 days in slow ones. After the seeds germinate, take away the glass plate and wait for most of the seedlings to be moved to a place suitable for growth and maintenance. It is worth noting that when the true leaves of flowers are no more than 2, never spray water from above them.
