Cultivation Techniques of Cut Lily Flowers
(1) Choose loose fertile and well-drained loam land for soil preparation. When soil preparation, fully decomposed organic fertilizer is applied 5 square meters per mu, and deep tillage is 30~35cm. Then, make a bed according to the specification of width 110~120cm and width 50cm, then spread calcium phosphate 10~15kg, potassium sulfate 4~6kg and pentachloronitrobenzene 0.8~ 1.0 kg every 100m2, and then dig 20~30cm to make the soil loose, broken, flat, soft and fertile. 3 days before sowing, irrigate once. ... fields planted with other bulbous flowers.

Lily cut flower management must plant
① time: according to the required flowering time, in principle, it can be planted at any time of the year. But it's best to avoid the hot summer season. When the air temperature is high, planting should be carried out in the evening, and artificial ventilation, shading and cooling should be carried out to ensure that the soil temperature should not be too high, and the soil temperature should be lower than 20 ℃ at the depth of 5 cm. ② planting method: ditch-on-demand, summer: first ditch and sow ball, then watering and covering soil; winter: first trench, watering and then sowing, covering soil. ③ density: generally 40 units per square meter, depending on variety

Storage and fresh-keeping of cut lily flowers
After the cut flowers leave the mother, the life activities such as transpiration and respiration of branches and leaves are still going on, so the water in the body is constantly lost and the organic matter is constantly decomposed and reduced. If you can not replenish water and nutrition in time, slow down the rate of water loss, flowers will wither in a short time, reduce or lose the commercial value of cut flowers. Therefore, the storage and preservation of fresh cut flowers is very important, which generally includes three contents, namely, pretreatment, storage and after-sale bottle insertion, promotion and preservation. ① pretreatment: cut flowers after harvest need to be pretreated immediately, main

Cultivation of Cut Lily Flowers
First, soil preparation selection loose fertile, good drainage loam land. When soil preparation, fully decomposed organic fertilizer shall be applied, 5 square meters per mu, and deep ploughing shall be 30~35 cm. Then make a ridge according to the specification of width 110~120 cm and walkway 50 cm, spread calcium phosphate 10~15 kg, potassium sulfate 4~6 kg and pentachloronitrobenzene 0.8~1.0 kg on every 100 square meters of ridge surface, and dig 20~30 cm again to make the soil loose, broken, flat, soft and fertile. 3 days before sowing, irrigate once. 2.

Harvesting, grading and packaging of cut lily flowers
The main results are as follows: (1) the harvest time ~ when the first flower seedling at the base is fully expanded and colored (the petals are natural), the flower can be cut. If a flower branch has more than 10 buds, 3 buds must be colored before harvest. (2) the harvesting method should be cut off with a sharp knife at 15 cm above the ground (about 5 mi 6 leaves). If it cannot be graded and bundled immediately after harvest, it must be refrigerated in clean water within 30 minutes (cooling and replenishing water). (3) grading, according to the length of flower diameter, the number of bud and stem.

Common Physiological Obstacles of Cut Lily Flowers
1. Yellow leaves and deciduous leaves caused by poor soil permeability, followed by salt accumulation, root damage caused by excessive watering, nutrient deficiency, excessive fertilization, water stress, low temperature and other reasons; therefore, improve the soil before planting, and avoid excessive watering. 2, leaf burning phenomenon occurs in addition to varieties, mainly due to excessive fluctuations in temperature, light, moisture, humidity and other factors; calcium deficiency and excessive fluorine content will also cause leaf burning. Therefore, in the daily management, especially in the facility cultivation tube
