To understand how edible fungi are cultivated and when flower seeds emerge, these three points are most likely to be ignored.

After ignoring the influence of light on flower seeds, proper light can increase the temperature of the soil and induce seed germination, especially for seeds breaking through the seed coat and rooting, which not only affects the emergence rate of seeds. it is also directly related to whether it can grow into good seedlings and strong seedlings. Therefore, from sowing to transplanting stage, we should try our best to meet the needs of light for flower growth, and the light intensity is a gradual transition from dark to weak light and then to natural light.

Neglect of seed germination suitable temperature dry seed germination not only has a certain water condition, but also must have a certain suitable temperature. For example, the suitable germination temperature of Cruciferae Snowball must be 5 ℃ ~ 20 ℃, and that of Gerbera must be? 20 ℃ ~ 25 ℃, the suitable temperature for primrose germination must be in the range of 15 ℃ ~ 18 ℃. Too high or too low temperature will affect the emergence rate of flowers, and even cause the occurrence of mildew and rot of seeds, which will greatly reduce the germination rate and seedling rate.

Ignore the seeds with large grains, solid skin or oily seeds during sowing, such as rose, rose, pomegranate, kumquat, magnolia and other flower seeds, which are suitable for sowing in autumn. Seeds with small grains and thin skin, such as chrysanthemum, asparagus, impatiens, hundred-day red, Lingxiao and other flowers, are suitable for sowing in late spring. Seeds that need high temperature to germinate should be sown in time after maturity, such as cyclamen, chrysanthemum, Zhu Dinghong and other flowers should be sown in early summer.
