Planting and fresh cut flower technology of blue lily

Technical operation rules for planting and fresh cut flowers of blue lily

1. Raising seedlings:

Blue lily is mainly propagated by ramets, and seeds can also be used to sow and raise seedlings.

The main results are as follows: (1) ramet propagation: when the blue lily grows to a certain period, the tiller seedling germinates from the terminal bud of the branch on the horizontal underground stem, and the leaf cluster of the tiller seedling and the mother plant grow separately, so it is easy to split. As long as the underground connected rhizome of each tiller seedling is cut open, it can be transplanted and planted. Ramet can be carried out all the year round, but generally the ramet is selected from March to April each year, and the combination of potted plants is changed to split. The method is to separate the over-dense old plants, and it is suitable to plant 3 trees in each pot, cultivated in the open field, or split after flowering (autumn). Each mother plant can be divided into 5 seedlings per year for propagation.

(2) seed sowing: take the new seeds collected in the same year, disinfect them with 500 times carbendazim for 30 minutes, wash them with clean water, soak the seeds with water for 24 hours, dry them in a 25 ℃ 30 min thermostat to accelerate germination, sow the seeds in a strip or on demand in the seedbed in time after the seeds are exposed to white. The seedbed matrix can be used to mix stone or Styrofoam particles with fertile topsoil. After sowing, it is covered with 60% sunshade net, drenched and moisturized, and germinated in about 30 days.

two。 Soil preparation and seedling transplanting:

(1) soil preparation: blue lilies like fertile soil with thiol pine, so before planting, the soil must be fully ploughed by machinery or manual work, and the drainage ditch must be divided by carefully ploughing and raking and leveling. The width of the border is 80m ~ 90cm, and more than 1000 kg of mature organic fertilizer per mu can be applied before planting.

(2) transplanting seedlings: the first seedling transplanting should be carried out in the period of two leaves in one heart and a height of about 5 cm. At this time, 3 seedlings can be planted in each hole with a row distance of 8 mi 10 cm. The second seedling transfer should be carried out when the seedling height is more than 10 cm. At this time, the seedlings should be planted separately, and the distance between plants and rows should be 1015 cm. The row distance of big seedlings is 20ml / 30cm.

3. Management after colonization:

Blue lily is native to southern Africa, like warm and humid climate and semi-shady environment, not resistant to frost, avoid the hot summer sun. It needs to grow in the environment with temperature above 5 ℃ in winter and cool and humid environment in sulfhydryl shade in summer. The requirement of soil is not strict, but there are many tillers and seedlings and grow vigorously in the soil which is rich in humus, fertile sulfhydrine and strong permeability. Varieties like fertilizer and water, but they are afraid of stagnant water, so they should water less when the temperature is low in autumn and winter to prevent rotting roots.

(1) fertilization: generally, water fertilizer is applied every 50 days or so, and each mu is sprinkled with high-quality compound fertilizer 10mur20kg with water, pay attention to prevent fertilizer and water from pouring on the leaves, and properly sprinkle water after fertilization; at the same time, urea or potash fertilizer is added appropriately according to the growth of seedlings, and 0.2% potassium dihydrogen phosphate is sprayed regularly as extra-root topdressing.

(2) watering: water is watered every 2 days in summer and autumn and twice a week in winter and spring to ensure that the soil is moist.

(3) ploughing and weeding combined with proper soil cultivation to prevent soil and water loss from rooting.

4. Pick, cut, cut flowers and package:

Cut flowers to avoid Rain Water foggy weather, local @ # @ 136 flowers @ cut all flowers in bloom, long-distance sales to pick and cut flowers with 4 small flowers, pick and cut together with flower stalks, individual plants are packed into boxes and stratified to prevent squeezing and damaging flowers during transportation.

For fresh cut flowers that need to be exported, insecticide or fumigation treatment may be required before shipment. The standard of commercial fresh cut flowers is: good color and texture, consistent opening, vase storage life of 7-10 days. The stems of fresh cut flowers are straight or nearly straight, and the stems of the same bunch of flowers are similar in length and thickness.
