The suitable soil temperature for the growth period of Lilium adenophorum was about 18-24 ℃. It should be noted that when the temperature is higher than 20 ℃, the rooting quality of lilies will decrease, so it is necessary to keep the soil temperature cool and do a good job of cooling, especially in summer. On the other hand, if the high temperature continues during the day, the height of the plant will be reduced, the number of flower buds will be reduced and the adverse effect of blind flowers will be produced. At night, the temperature should not be lower than 15 ℃, otherwise, it will lead to buds falling, leaves yellowing, and then reduce the ornamental value.
Insufficient light will affect the formation of flower bud, but too strong light will also affect the quality of cut flowers. Therefore, we should keep a reasonable amount of light
During the growth period of Lilium oxyphyllum, according to the specific needs of the corresponding shading work and light supplement measures to promote the healthy growth of plants. Generally, shade is needed in the early stage of growth, which can improve the height of plants to a certain extent, especially in summer.
Can be covered in the canopy around the shade net, block too strong light, so as to avoid high temperature in the canopy to cause damage to the plant.
In spring, summer and autumn, the noon temperature is higher, so the shed film and top window can be opened in the morning for ventilation, and the humidity can be adjusted in a slightly lower temperature environment, so as to avoid the drastic change of humidity in the high temperature stage. In winter, we should take some heat preservation measures, choose to change the air when the temperature is high at noon, and ventilate intermittently.
Gong Deng lily is easy to be affected by high salt, which will lead to water shortage. It's better to irrigate water for 20-30 minutes every day from the 17th week after planting. The first 8 weeks after planting should be irrigated from the top, and the ball seat belt should be changed in the next 9 weeks. The watering can be stopped 17 weeks after planting. When watering, pay attention to the control of water volume and prevent water accumulation.
Choose fertile, loose, well drained soil matrix, can regularly disinfect with fungicides, which is conducive to the prevention of diseases and insect pests.
At the time of land preparation, the fully decomposed organic fertilizer can be spread. After being applied as the base fertilizer, it can be evenly mixed on the soil surface, generally 30 cm thick. If the plant growth is not strong enough during the growth period, it may be caused by the lack of nitrogen fertilizer. In this case, quick acting nitrogen fertilizer can be applied. Soil topdressing is generally 2-3 times, and foliar topdressing can be done once a week. Remember to wash plants after topdressing to prevent burning leaves.
Generally, seed propagation and ball propagation are two ways
