The three most easily overlooked points in edible mushroom cultivation methods and flower seed germination
Overlooking the effect of light. After flower seeds are sown, appropriate light can increase the soil temperature and induce seed germination, and it is especially important for seeds to break through the seed coat and send out roots and sprouts. This not only affects the seed germination rate, but is also directly related to whether good, strong seedlings can be grown. Therefore, from sowing to transplanting, the light needs of flower growth should be met as much as possible, and light intensity should be a gradual transition from shade to weak light and then to natural light.
Overlooking the suitable temperature for seed germination. In addition to certain moisture conditions, the germination of dry seeds must also have a certain suitable temperature. For example, the suitable germination temperature for sweet alyssum (Lobularia maritima) in the Brassicaceae must be 5°C to 20°C, the suitable germination temperature for Gerbera (Gerbera jamesonii) must be 20°C to 25°C, and the suitable germination temperature for Primula (Primula malacoides) must be within the range of 15°C to 18°C. Too high or too low a temperature will affect the flower germination rate, and may even cause seeds to rot, greatly reducing the germination rate and seedling survival rate.
Overlooking the sowing time. Seeds that are large, have a hard outer coat, or contain oil, such as the seeds of Chinese rose (Rosa chinensis), rose (Rosa rugosa), pomegranate (Punica granatum), kumquat (Fortunella margarita), and southern magnolia (Magnolia grandiflora), are suitable for sowing in autumn. Seeds that are smaller and have a thin, loose outer coat, such as chrysanthemum (Chrysanthemum morifolium), asparagus fern (Asparagus setaceus), garden balsam (Impatiens balsamina), crape myrtle (Lagerstroemia indica), and Chinese trumpet creeper (Campsis grandiflora), are suitable for sowing in late spring. Seeds that need high temperatures to germinate should be sown promptly after maturity; for example, cyclamen (Cyclamen persicum), cineraria (Pericallis hybrida), and amaryllis (Hippeastrum rutilum) should be sown in early summer.
