Planting management of Fritillaria thunbergii

1. Seed cultivation and treatment of Fritillaria thunbergii is mainly seed propagation. ⑴ seed cultivation: when picking Fritillaria from June to July, the bulbs with a diameter of more than 1 cm, disease-free and damage-free were selected as seeds. Bulbs are planted according to large, medium and small respectively, so that they can be planted while digging. Use 100kg bulbs per mu. It can also be planted in holes, starting from the second year after planting, spraying Zhencaoning before emergence in March every year, and pulling out weeds in time after emergence in early April. And apply rare human and animal dung water. From late April to early May, topdressing was applied again. From July to August, the fruit is full and swollen, and the shell is yellowish brown or brown. Cut the fruit when the seeds have been dried, and ripen the fruit while it is fresh or with a shell. ⑵ seed ripening treatment: shelled seeds, sifted fine humus soil, water content less than 10%, a layer of fruit soil, packed in a breathable wooden box, put in a cool, damp place. The threshed seeds should be mixed with 1 ∶ 4 (seed: humus soil) in the storage room or in a breathable wooden box. During storage, the soil was kept moist, the pericarp (seed coat) expanded for about 40 days, the embryo length exceeded the seed longitudinal axis by 2pm and 3, and the embryo apex was curved. Complete the morphological ripening of the embryo. It can be sown. 2. Sow seeds from September to October before snowing (Fritillaria thunbergii, the same below). Strip sowing, sowing or split-on-demand sowing with capsules can be done. Strip sowing: open a horizontal trench on the border surface, 1.5-2 cm deep; spread seeds mixed with fine soil or plant ash evenly in the ditch. Cover 3 cm of fine humus soil and cover the border with mountain grass or leafless branches. Use 2-2.5 kg of seeds per mu. Sowing: spread seeds evenly on the border surface, with 3 000-5 000 seeds per square meter. Overwrite the same broadcast. On demand: when the fruit is not dry. The undried fruit was divided into 3 lobes, and the holes were opened according to 5-6 cm plant spacing on the border surface, 1 flap per hole and 3 cm covered with soil. This method is more labor-intensive, but the emergence rate is high.
