The new iron cannon lily is a cross-breed lily lily that can be cut directly from the lily and Taiwan lily. It usually takes about 7-8 months from sowing to flowering. The lily of the new artillery is white and beautiful, with a beautiful flower pattern, a large flower pattern, and a strong aroma. It is deeply loved by consumers. Since Lilium cannonii can be used to produce cut flowers directly from seeds, the production cost is greatly reduced compared to the conventional use of bulbs to produce lily cut flowers. Compared with other musk lily, this flower has less pests and diseases, is resistant to high-temperature summer weather, and is easy to cultivate and manage. Therefore, it is also favored by many flower growers. The new iron cannon lily market has a great potential for development. It is a rookie in the Lily family of cut flowers. In recent years, its output of cut peanuts at home and abroad has continuously increased.
First, biological characteristics
The plant height of the new iron cannon lily is about 1.2-1.5 meters, and the stem is erect and hard. The leaves are dark green with 1 to 4 flowers per stem. The flower color is white, the petal is thick, and the vase has a long shelf life; the flower expands upwards, and some people call it "Lily Sky Lily." This characteristic is beneficial to use and packaging. Usually sowed from November to February, planted from April to May, and flowered from July to September. Most species of new iron cannon lily can cut 2-3 times a year.
Second, breeding methods
1. Seeding and sowing can be planted between November each year and February of the second year. New iron cannon Lily Sandy soil, sowing matrix to use a loose, water-permeable fine acidic substrate (charcoal is very good). Because it is very fertile, it is best to use a sufficiently mature organic fertilizer in the lower part of the seedbed to ensure nutrient supply during seedlings. The planting density of the new lily can vary depending on the method of sowing. If sowing in the seedling tray, when the seedlings grow to 1-2 true leaves when transplanting, can appropriately increase the planting rate per unit area, sowing 8000 seeds per square meter is appropriate; if you take the nursery bed live, the seedlings are not transplanted For direct colonization, a row spacing of 2 cm x 6 cm is appropriate. The optimum thickness of the cover soil is 0.5 cm. The optimum temperature for the early sprouting of Lilium candidum was: night temperature 5°C, alfalfa temperature 15°C; the optimum temperature for late germination and seedling stage was: night temperature 15°C, temperature 20°C. After sowing, it is best to use a film to keep the humidity. The seedlings can be planted about 20 days after sowing under the above temperature conditions, and the peak of emergence can be reached within 30 days.
In addition, due to the fact that most of the new lily Lily hybrids are F1 hybrids, the length of seed dormancy differs greatly, resulting in irregular emergence, and some seeds are in the sowing matrix for a long time since they have not passed dormancy. Do not germinate and rot. The method of breaking dormancy is to use gibberellin, a hormone that can break the dormancy of seeds. Seed soaking with low concentrations of glucoraban, the effect is good. It is advisable to treat the seeds with a suitable concentration of fungicides before sowing. This will not only increase the emergence rate, but also reduce the disease at the seedling stage.
2. Scale the cuttings with mature and robust bulbs, select the second and third layers of healthy and hypertrophic scales, peel them off and rinse them with water. The cutting substrate is preferably peat with a diameter of 0.2 to 0.5 centimeters of water. The specific approach is: insert 1/3 of the scale into the medium, to prevent damage to the scale; the scale spacing is about 3 cm. After inserting, keep the substrate moist, avoid moisture and prevent scales from rot. The relative humidity of air is maintained at about 90%, and the temperature is maintained at 21°C-25°C. There is no special requirement for light, but long days are more conducive to the formation, growth and development of bulbs. After 2 weeks, small scaly protrusions can form at the base of the scale.
Third, cultivation and management
1. The best temperature condition for early germination of Lilium sinensis seedlings during seedling management is temperature 15 °C night temperature 5 °C. The suitable temperature in the late stage of germination and seedling stage is temperature 20 °C, night temperature 15 °C. If the temperature is high at the time of germination and germination, it will cause seedlings to grow weak, and it will cause an increase in the proportion of single flowers at the time of flowering.
2. When the planting seedlings of the new lily planting lily grow to 4-5 true leaves, they can be planted. It is best to use a half-high bed for planting. The bed width is 0.8-1 meter, and the spacing is 10 cm x 15 cm. The depth of colonization should be moderate, "deep not buried in the deep, shallow rootless." Immerse water immediately after colonization.
3. Water and Fertilizer Management New iron cannon Lily humid soil, but not too wet; not resistant to drought. After planting, it is best to cover the bed with straw to keep the soil moisture. Pay attention to drainage during the rainy season.
The new iron cannon lily is very hilar, if the fertilizer supply is insufficient, it will cause early seedling jointing, short flowering branches, increased pests and diseases, and the proportion of single flowers will increase. Therefore, fertilizer management must be strengthened. The seedling stage will begin to supplement the fertilizer. Generally, before and after the first true leaf grows, the seedlings begin to use potassium dihydrogen phosphate, acidic amino acid compound fertilizer and other foliar fertilizers. Before planting, the seedbed should be applied with basal fertilizer, and the base fertilizer should preferably be fully decomposed organic fertilizer. The content of effective elements is approximately to meet the following criteria: nitrogen 3.5 kg/100 m2; phosphorus 3.0 kg/100 m2; potassium 1.5 kg/100 m2. Fertility is also very important during the growth period, and the first time after planting, the first fertilizer application can be started. When the seedlings begin to be jointed, the amount of fertilizer should be increased in time. In general, the weight of a growth cycle must basically meet the following criteria: nitrogen 2.3 kg/100 m2; phosphorus 2.0 kg/100 m2; potassium 1.0 kg/100 m2.
4. The temperature and light of the new iron cannon Lily Hi light filling environment, can tolerate a certain degree of high temperature. However, sustained high temperatures above 30°C will be detrimental to their growth and development. In areas such as north China and northeast where summer heat and light are strong, shading nets should be constructed in a timely manner.
5. Other management measures Because the root system of the new iron cannon lily is shallow, it is prone to lodging. Therefore, it is necessary to build a support net in due course. When the seedlings grow to 10-15 cm in height, the first layer of support nets is to be erected; when it is about 50 cm long, a second layer of support nets will be constructed. At least two layers of support nets must be guaranteed.
6. Diseases and Insects and Diseases Prevention and control of new iron pests Lily seedlings of food-grade pests, can be combined with water octogenin or trichlorfon prevention and control; flowering locusts can use dichlorvos, fasting and other control. The main diseases during the seedling stage are blight and root rot, and they are controlled by the seedlings, chlorothalonil, fluocin, and so on. The leaf blight in the growing season can be controlled by mancozeb, acetaminophen, chloroquine and so on.
