Detailed Explanation of Lily Planting Methods and Management Techniques

For lily planting, the site should generally be a loose, fertile sandy loam with a low groundwater table. After proper deep plowing, harrow level and form beds about 1.5 m wide and about 20 cm high, with furrows about 30 cm wide between the beds. At the same time, cut field ditches and field-edge ditches about 50 cm wide to facilitate drainage and irrigation. Before plowing and leveling the soil, apply base fertilizer first. Generally, per mu, apply 2500-3000 kg of decomposed farmyard manure, 100-150 kg of bran fertilizer, and 15-25 kg of superphosphate. After application, plow into the soil and then harrow level.

Before "Start of Winter," select bulbs harvested in the current year for planting. Before planting, carefully cut open multi-core seed bulbs with a small bamboo knife (do not use iron tools to cut or tear by hand). When planting, open seed furrows 7-10 cm wide on the bed surface, and according to a row-to-plant spacing of 30 cm × 15 cm, place the seed cores facing upward in the furrows, then cover with about 3 cm of loose soil. About 15 days after planting, apply a "wintering fertilizer" once, applying about 2500 kg of decomposed cow pen manure per mu, preferably enough to cover the bed surface, and sprinkle an appropriate amount of decomposed dilute manure water on the surface. When the seedlings emerge the following year and reach 12-15 cm in height, carry out one plowing and weeding, and combine it with applying about 1500 kg of decomposed manure water per mu. When the underground bulbs begin to form and swell, apply an appropriate amount of nitrogen fertilizer once more (seed-production fields should not be given nitrogen chemical fertilizer). After that, when the flower buds opening on the aboveground part turn red, remove them to promote concentrated nutrient supply to the underground bulbs and increase yield. The removed flower buds should be disposed of in a centralized way and should not be left to rot in the field, so as to prevent stem rot and seedling death.
