Remove fruit shells and blighted grains, mix well with wet sand and seeds in the ratio of 3 ∶ 1 (volume ratio), and layer into pits or wooden boxes under the forest or indoor. Turn the stratified seeds every 10 days or so to keep the pit (box) moist moderately and evenly.

2. Sowing seeds

As the bulb of the 2012 Fritillaria seedlings is small, it is suitable for dense sowing, in order to evenly sow on the border surface, the seeds do not overlap for the degree, about 25 kg per mu. After sowing the seeds, immediately cover with sifted humus or rotten, sifted compost, about 2 cm thick, and then cover with a layer of straw or wheat straw to preserve moisture.

3. Seedbed management

After thawing in early spring, before the seedlings are unearthed, remove the covered grass, gently rake the topsoil of the seedling bed, and then cover the grass. When about 20% of the seedlings emerge, remove the cover grass. After emergence, the seedlings were raised once by applying rotten thin human feces and urine or 0.5% urea solution, and once again in late April to promote bulb growth. In addition, the seedlings of 2012 are afraid of sun exposure, so it is necessary to build a low shed for shade, with a shade degree of about 50%, and open the shed to refine the seedlings on overcast and rainy days.

4. Transplanting

The field used for transplanting should also be fertilized by soil preparation, ditch and strip sowing. After fertilization, you can first sprinkle a thin layer of humus or fine soil in the ditch, and then discharge the bulb in the shallow ditch, the plant distance is about 3 cm. The border is covered with straw, crop straw or twigs. Generally, it can be excavated and processed within 1-2 years after transplanting, and most of the commodity specifications reach the first-class standard.
