The lilies production refers to the production process by which the lilies are harvested once, without having to go beyond any treatment in the soil and to cut flowers again. That is to say, after the first harvest, the process by which, by natural freezing, the seedlings fall asleep and the flowers grow again. The production of lilies is now a major advantage in the production of flowers in the north, which significantly reduces the cost of inputs into the production of lilies。
The premise is that there are enough healthy seed balls. That is to say, after the first flower harvest, a careful examination of the health of the balls, if the ball is damaged and the disease rate is high, there is no value in the production of the bouquets, and there must be sufficient cold periods。
The production of the second flower must be planned from the very beginning, and it must be prepared from the very beginning. The concrete approach to recovery is that when a flower is purified, it takes at least one month to properly manage the root under the ground for a longer period. A permutation phase should be followed up one to two times with insecticides and microbicides。
When they are strengthened, they must be pre-cooled, starting with the opening of the shed, and during the day, with the curtains, i. E., with a piece of grass, or with a shade of sun. This will gradually reduce normal temperatures and will not affect the quality of the runners by sudden drops from high temperatures to ice points, a process that takes 5 to 10 days。
After the pre-cold end, we can do the cold treatment. The practice is to conduct counter-conventional management operations based on the pre-cold phase, whereby the curtains are dropped during the day and rolled up at night until the soil in the shed is frozen to 3 to 4 centimetres, at which point the temperature of the runner is best maintained at -1. 5°c。
Put the straw curtains down completely after pre-colding and try not to let the sun shine into the shed so as not to unfrozen and suffocate the shed, without drawing curtains during the day. The suffocation should correspond to a period of recovery of at least one month or more。
The thaw is followed by unfrozen treatment. When freezing time meets our requirements, we can gradually warm the soil and slowly unfreeze it so that it does not suddenly affect the quality of the tubers. This is done by opening the straw curtains in the form of flower curtains during the day, allowing the shed to gradually receive sunlight and the temperature in the shed to rise slowly, taking 7 to 10 days. When the preheating time is met, we can roll up the straw curtains completely every day until the soil in the shed is completely unfrozen。
The soil is completely unfrozen and is managed for hydrofertilizer. It should be noted that the soil in the shed is completely unfrozen before the water is targeted, and the timing of the water is determined by the dampness of the soil. Insecticides and microbicides should be applied when water is poured, along with plant growth regulators that break sleep. After cleaning up the groceries before watering, a layer of decayed organic fertilizer is laid on the surface to capture the fertility of the high soil and to facilitate the growth of the seedlings. Then you can run like a flower。
