Cultivation techniques of pot cut flowers in open greenhouse of lily

The lily is a cold-resistant bulb flower of the lily family, which is light-loving and fertile sandy soil. It has peculiar flowers, many colors and beautiful colors, and potted flowers are used for both purposes, giving people a sense of wealth and elegance, which is very lovable. It can be planted all the year round, with large flower yield and high economic benefits, and it has developed rapidly this year. But the first growers often have poor growth, few flowers and diseases. For this reason, combined with the planting practice, the author briefly describes the following pot cut flower cultivation techniques of lilies in open greenhouse.

I. planting method and time

Whether open field or greenhouse planting lilies, should choose fertile and breathable sandy soil, will be fully applied high-quality farm fertilizer 3000 kg / 667m2 and phosphorus, potash fertilizer each 25 kg / 667m2, turn 30 cm deep, Tuba fine loose, hit into a 20 cm high, 80 cm wide planting belt, belt distance of 20 cm; before planting with ditch irrigation or spraying method to irrigate once.

1. Open field planting

Lilies should be planted in early spring from March to April, when the ground temperature of 15 cm is 5-8 degrees Celsius. The depth of the planting ball is 1215cm, but the diameter of the ball with a circumference of S8cm 10cm 12cm can be 10 cm deep, the row spacing is 10cm 15cm X 20cm, and the new buds can break the soil in 3 weeks. If planted earlier to prevent frost damage of new branches and leaves, straw can be used to cover it. It takes about 15 weeks from planting to flowering, but the time of flowering is related to the variety. The above-ground leaves 10-15 cm when cutting flowers, and the corm can also develop and blossom in the next season. The lily bulb has a large flowering, but the bulb used for reproduction has a good effect on the bulb with a circumference of 8cm and 10cm.

2. Planting in greenhouse

Because the lily blossoms need sufficient light and air, the light transmittance of the plastic greenhouse is reduced by 20% to 30%, which can only plant bulbs with a circumference of more than 12 cm and 16 cm. Before planting, spray 1000 times of chlorpromazine or 1000 times of methyl topiramate to disinfect the soil. The planting ball must be a frozen ball, the planting method should be the same as the open field, the greenhouse temperature should be controlled at about 15 degrees Celsius, such as January 15 species blooming on April 20, according to the time needed, you can plant by yourself. however, it is difficult for greenhouse planting to blossom in December, January, February and month, so time is not enough, dark or lack of light will make flower buds wither and dry; it is best not to plant them from October to December 15. If there is a low temperature, the seed ball can be planted on a plate to take root and then moved into the greenhouse, so that it can bloom in about 5 weeks. Potted plants can also be planted in the greenhouse, and the potted soil can be made of 2 parts of fertile soil, 1 part of coarse sand and 1 part of peat, with a pot diameter of 18 cm and 24 cm. Each pot has 1-2 balls, 5-6 cm deep, and can be poured with 1 ‰ phosphate liquid fertilizer, and can germinate and break the soil in 3-4 weeks.

II. Harvest and preservation of lily bulbs

Lily bulbs should be harvested later in autumn and should not be frozen before harvest. Be careful when pilling, you must dig up to 30cm, because the seed ball is buried in 12cm to 15cm, and the root should be pulled out together with the ball, otherwise the corm is easy to be damaged and infected with disease, but also easy to dry up. After getting up, the ball is dried; when digging, the root brings a lot of soil, it should be washed with water of 5-10 degrees Celsius, and the root and bulb should be protected when washing. After washing, store the balls separately, put them in the box and add some peat soil, put them in a well-ventilated room at 5 degrees Celsius. After 4 weeks, the temperature drops to 0 degrees Celsius and to-2 degrees Celsius after January 15. If the bulbs sprout, there is no power to grow. Transport to use a small box, keep 2 degrees Celsius; low temperature for a long time, dormancy for 6-7 months, such as March 15, the temperature dropped to-3 degrees Celsius 5 degrees Celsius, bulbs can be maintained for a year.
