Detailed Explanation of Lily Seed Cultivation Methods and Techniques

Nursery Stock 0 views
Lilies are grown for their bulbs, which are used as food or medicine and have the effects of moistening the lungs, relieving coughs, clearing the heart, and calming the spirit; in recent years, they have become a widely planted cash crop among farmers. The cultivation methods and key technical points for superior lily varieties are introduced below: Scale propagation method. After harvesting lilies, select large bulbs that are robust, undamaged, and free from pests and diseases, cut off the base, keep the scales, and dry them in the air for several days. On a prepared seedbed, open horizontal furrows at a row spacing of 15 cm, with a furrow depth of about 7 cm, then place 1 scale into the furrow every 3-4 cm (with the tip of the scale facing upward when placing), cover with 3 cm of soil after planting, and then cover the soil surface with a layer of rice straw. After the scales are planted, they take root and sprout in the same year, and seedlings can emerge in the spring of the second year. After another two years of cultivation, when the underground bulbs reach an individual weight of about 50 g, they can become superior lily varieties. Using the scale propagation method requires about 150 kg of lily seed scales per mu. Small bulb propagation method. When cultivating superior varieties with small bulbs, the seedbed row spacing should preferably be 24-26 cm, and the furrow depth should preferably be 5-7 cm. Place one bulb every 5-7 cm in the furrow of the seedbed. After emergence in the spring of the second year, strengthen field management, and they can be harvested in autumn. At harvest, decide whether to keep or remove them according to the weight of the cultivated superior lily varieties, that is, those with an individual weight of 50 g or more can be selected for planting as superior varieties, and those with an individual weight of less than 50 g should continue to be cultivated. Seed propagation method. From September to October each year, collect nearly mature lily capsules (the nearly mature fruits of lilies), place them in a ventilated and dry room to dry and after-ripen. Then use the sand storage method (build a burial pit with bricks in a cool house or basement, spread 5-7 cm thick fine sand at the bottom of the pit, then arrange lily bulbs or fruits on the sand, cover with 3-4 cm of sand, and repeat in this way, with a stacking height of preferably 100 cm) to treat the seeds. In the spring of the second year, sieve out the seeds and sow them in spring. The seedbed row spacing should be 10-15 cm, and the bed surface and compartment furrow should preferably be 3-4 cm. Sow the seeds into the compartment furrow, cover with 2-3 cm of soil, and then add a layer of rice straw on the bed surface (to enhance the heat preservation and moisture preservation effect of the bed surface). After the seedlings emerge, strengthen field management, and after three years of cultivation, superior lily varieties can be obtained. Bulbil propagation method. Lily plants grow bulbils in the leaf axils. After the flowers fade in summer, the bulbils fall off by themselves. Place the fallen bulbils into the seedbed and then, according to the conventional method for cultivating superior lily varieties, strengthen field management and rationally manage fertilizer and water, and superior lily varieties can also be cultivated.
