Conservation and Management of Lily Planting

one。 Temperature management

During the first two weeks of lily planting, the temperature should be controlled at about 4mi 13 degrees Celsius, and then the temperature can be gradually increased to promote stem and root growth. If the temperature is too low, it will prolong the growth period of lilies, and the temperature higher than 25 degrees Celsius will cause the imbalance of root-shoot ratio of potted lilies, which will lead to the decrease of product quality.

two。 Water management

As water will affect the total salt content of the cultivation substrate, the salt content of irrigation water should be 0.5mS/ cm or less. Watering is best in the morning or when the temperature is lower in the morning. Lily bud when properly reduce the number of watering, can not pour water to the leaf surface, to avoid "leaf burning". After the end of the "leaf burning" period, you can spray and water, especially at high temperature, foliar spraying can not only keep the leaves bright green, but also avoid burning leaves at high temperature. Keep sufficient water in the later stage of bud growth to avoid drying and shrinking due to falling buds or buds.

three。 Fertilizer

Lily is a bulbous flower, which can be fertilized three times during the growth period. Do not apply fertilizer during the period of stem and root formation. After the end of "leaf burning", nitrogen fertilizer is the main fertilizer, supplemented by calcium fertilizer, phosphate fertilizer and potassium fertilizer. Calcium nitrate is mostly applied in the first fertilization, about 5 grams per pot. In the second fertilization, potassium nitrate can be applied during the bud growth period.

four。 Light

Potted lilies have different requirements for light intensity in different growth periods, shading treatment should be carried out in the bud stage, if the leaf temperature is too high, it should also be shaded properly; in other growth periods, light should be strengthened, especially in the flower development period.

five。 Relative humidity and ventilation

Potted lilies require air relative humidity of 80% Mur85%. Too high relative humidity will lead to a variety of diseases, and too low will affect the normal growth rate of the plant. During ventilation, drastic changes in air relative humidity should be avoided, otherwise the product quality will be reduced. During the "leaf burning" period, ventilation can be appropriately increased to reduce "leaf burning".
