Introduction and breeding of Japanese new iron cannon lily

I. characteristic characteristics

In 2004, the new iron cannon seed was introduced from Japan for planting, with a plant height of 40 meters, a white color, a trumpet-shaped flower and a terminal flower. After flowering and raising balls, it only takes about 8 months from sowing to flowering, with a large reproduction coefficient, sterile and some excellent characters of Lilium. After more than two years of trial planting and promotion in Daheng Science and Technology Park and Ta Qian Lily Base in Nanping City, the suitable sowing time of New Iron cannon Lily is from late September to mid-October, and flowers can be picked 9 months after sowing. New iron cannon lily is a hybrid of Japanese high sand lily and Taiwan iron cannon lily. It has large flower shape, pure white color and rich aroma. It belongs to high temperature lily. It likes warm and humid environment and avoids dry, cold and strong sunlight. The suitable temperature for growth is 25: 28 ℃ in daytime and 18: 20 ℃ at night. The natural flowering period of the cultivation is 4mi-May, and the cultivation can blossom year after year. It is one of the excellent varieties of cut flowers.

Second, the main points of cultivation

1. Sowing: new iron cannon lily likes sandy slightly acidic soil, other lilies like fertilizer, and more rotten organic fertilizer can be applied when raising seedlings. When sowing, the seedbed can be sowed with row spacing lO cm and plant spacing 3cm, and sand 0.5cm after sowing. The optimum temperature for germination of new iron cannon lily is 15Mel 20 ℃. The most important thing is to keep moisture after sowing. If the condition is suitable, it can emerge in 15 days, and it can be planted in 30 days or so.

2. Planting and management: after the first true leaf was unfolded, acidic amino acid compound fertilizer was sprayed. When the seedling grows to 5 true leaves, it is planted. When planting, we must use high border cultivation, apply sufficient amount of organic fertilizer, the distance is 12 cm × 12 cm, and fully water after planting. If the leaves turn yellow after the slow seedling, the leaves can be sprayed with ferrous sulfate of LBE500. When the plant height is about 20 cm, pay attention to screening to prevent lodging. New iron cannon lily likes plenty of sunshine but can not bear high temperature. the long duration of high temperature above 30 ℃ will affect its production and development. It is necessary to build a sunshade net at the right time in summer. The leaves should be cooled by spraying water at noon when it is too hot, and the soil should be ploughed and loosened in summer combined with weeding.

3. Harvest: generally, the seedlings sown from January to February begin to blossom one after another in September. Because of the seedling cultivation, the flowering period is not regular, and the flowering period lasts about 2 months. When the buds are slightly white, the cut flowers can be listed on the market.

III. Regulation of florescence

The reasonable arrangement in the production of fresh cut lily flowers to ensure the use of flowers during the festival and the balanced supply of flowers at ordinary times can improve the economic benefits of planting flowers. The measures to adjust the production period are generally taken:

1. Variety collocation: there are many varieties of cut lilies, which can be divided into early, middle and late flowers according to the production period of Dutch lilies.

2. Batch sowing: as the flowering period is comprehensively affected by many climatic factors such as temperature, sunshine, light intensity and so on, the climatic conditions of different seasons should be taken into account when arranging the planting date, and the seeds should be sowed in stages, usually every 15 days or so. The sowing amount is predicted according to the change of climatic conditions, which can ensure the balanced flower yield.

3. Raising temperature and replenishing light to promote flowers: in case of continuous low temperature, overcast and rainy weather in winter and spring, artificial lighting and electric heating can be used to increase the temperature of soil and air in order to promote early flowering. In the greenhouse, a 400 watt incandescent lamp can be hung on every 8mil 10 square meter nursery bed. Replenishing light for 6 Mel for 8 hours a day can prevent blind flowers and blossom early.

4. The utilization of silver thiosulfate (sTS), once treated with STS or sprayed with 0.5mm / Y+STS once every two weeks, can solve the phenomenon of bud drop and dry up of lilies, promote bud development and maintain florescence.

5. Cold storage of cut flowers: if due to abnormal climate, a large number of lilies bloom earlier and the market demand is not strong, then the method of cold storage is adopted. The storage period of cut lilies is 2-3 weeks under the temperature of 0 ℃.

IV. Reproduction

The first year of seed cultivation. From the seedling to the heading, almost all the nutrients absorbed by the root were supplied to the aboveground part, and the underground bulb basically stopped growing. It is only after cutting the flower that the bulb begins to produce and expand, and the aboveground part should be managed well after cutting the flower in order to raise the ball well. Only when the upper part of the local area dies naturally can it be covered with 0 seed balls. When digging bulbs, you should choose fine weather, be careful not to damage the external scales, and remove the rotten and damaged scales in time. Store in a cool, ventilated place after being dug up. The dormancy degree of the new iron cannon lily is very shallow, and the greenhouse and greenhouse can be planted at any time according to the need, even if planted immediately. In cold storage, the seed balls are graded, sterilized, then packed in plastic boxes, filled with sawdust or sand, and stored in 0 Murray 2 ℃ cold storage.
