Planting and management techniques of lilies

The planting land of lilies should generally choose loose, fertile sandy loam with low groundwater table. After appropriate deep turning, rake and level the border, requiring a width of about 1.5 meters, a height of about 20 centimeters, and a width of about 30 centimeters between the borders. At the same time, open a good width of about 50 centimeters of the field ditch and field edge ditch to facilitate drainage and irrigation. The basic fertilizer should be applied before ploughing. Generally, 2500-3000 kg of rotten farm manure, 100-150 kg of bran fertilizer and 15-25 kg of superphosphate should be applied per mu, and ploughed into the soil and raked flat.

Before "the Beginning of Winter", the bulbs harvested that year were selected as seeds. Before planting, carefully cut the multi-core seed ball with a small bamboo knife (do not use iron cutting or hand breaking). When planting, the seed groove was made into a width of 7 cm × 10 cm on the border surface, and the seed core was placed upward in the seed ditch according to the row spacing of 30 cm × 15 cm, and then covered with loose soil about 3 cm thick. After planting for about 15 days, it is appropriate to apply a "overwintering fertilizer", about 2500 kg of rotten cow pen manure per mu, it is appropriate to cover the border, and the surface layer should be irrigated with appropriate amount of rotten dilute manure water. When the seedlings were unearthed at a height of 12cm to 15cm in the following year, one-time ploughing and weeding was carried out, and about 1500 kg of rotten manure water was applied per mu. When the underground bulb begins to form and expand, nitrogen fertilizer should be applied again (it is not suitable to apply nitrogen fertilizer in the field). Since then, when the local upper flower buds turn red, they will be removed to promote the concentrated supply of nutrients to the underground bulbs and increase yield. The removed buds should be treated centrally and should not be allowed to rot in the field so as not to cause rotten stems and dead seedlings.
