When will buttercup be sown?

Buttercup can be obtained by sowing, bulb ramet and tissue culture to obtain young plants for pot planting, and sowing is often easily affected by air temperature due to different selection time, and different regional environment, sowing time will also be different. So, when will buttercups be sown? Next, please follow the editor to discuss it!

1. Sowing time of Ranunculus

The sowing of buttercup is generally carried out in autumn, between August and October every year, but mostly in September and October, because the survival rate is relatively higher when sowing during this period. Because the seeds of Ranunculus ranunculus are more favorable for germination when the temperature is between 5-15 ℃, but when the temperature is lower than 5 ℃, the embryos of the seeds are stagnant, which is not conducive to germination, while when the temperature is higher than 0 ℃, the seeds are easy to mildew and even rot in the hot and humid environment, and the survival rate is relatively low.

Thus it can be seen that the sowing of buttercup is not suitable in summer and winter, because the summer temperature is generally higher than 20 ℃, while the winter temperature is generally lower than 5 ℃. So, the temperature in spring is more suitable, is it suitable for sowing? In fact, buttercup is different from many other potted flowers and plants. It is not suitable for sowing in the warm spring season.

Second, sowing in different regional environments

In the above statement, the editor has already mentioned that the sowing of buttercups is usually carried out in September-October in autumn, but the timing is different in different regional environments. Because the regional environment is different, the temperature environment is also different, and the sowing time of buttercup is mainly determined by temperature. For example, in the northeast, because the temperature tends to fall better and colder than other areas, the sowing time of buttercups should also be advanced, usually in August. Compared with Guangdong, for example, the cooling time is often delayed, so the sowing time should also be postponed appropriately, and it is appropriate to sow around October.

For most parts of the south, if we want to sow seeds ahead of time, we need to accelerate the germination of the seeds at low temperature so that they can sprout as soon as possible. The two most important links in the process of accelerating germination of buttercup seeds are soaking and cold storage, which need to be soaked and put in the freezer after soaking. During this period, it should be noted that there is not too much water, otherwise it is easy to rot; when there is insufficient water, it should also be replenished in time, so as not to affect the germination of seeds.
