Cutting method of Carnation

The reproduction of carnations can be divided into asexual reproduction and sexual reproduction. Sexual reproduction often has low seed setting rate, great variation of seed progeny characters and slow seedling growth, so it is rarely used in production. Asexual propagation is widely used in production, mainly cutting propagation, which has the advantages of rich cuttings, stable characters and quick effect.

Carnation is the most suitable for cutting propagation. The cutting time is unlimited, except in the hot season, it can be propagated in other seasons. Among them, the survival rate of cuttage in early February was the highest. Cuttings should choose mother plants with good varieties, strong growth, neat flowering, few nodes, good quality and no diseases and insect pests, and peel (preferably not with scissors) their well-developed side branches 6 to 10 cm long as cuttings. When stripping, you should peel off the leaves together, but be careful not to damage the parent plant.

If cutting in winter, the cuttings should take heat preservation measures, which can be carried out in the greenhouse or plastic film shed. The seedling bed soil should be ploughed with loose sandy soil rich in humus. Before cutting, the land should be ploughed once, and it is best to remove part of the soil out of the shed for two days, and then mixed with 1x3 rice chaff ash and coarse sand to make the soil loose. If the weather is sunny, the plastic film can be removed and the soil can be exposed for 3-4 days for disinfection, which is more reliable. The soil was sprayed with water one day before cutting, and the soil was moderately dry and moist the next day.

When cutting buds are drenched with water, the insertion depth is about 2 to 3 cm, and the plant spacing and row spacing are 5-6 cm. Water immediately after insertion and cover with shade (no more watering within 10 days, until the topsoil turns white, to avoid getting wet and rotting the roots). When the temperature is kept at 10 ℃-20 ℃, it can take root in about 20-25 days and transplant in about 45 days.

When transplanting, gently raise the seedling from the root soil, plant it into the seedling bed, damage the root system as little as possible, and water it after planting. The fertilizer was applied once after 10 days and again every 10 days. When the seedling grows to 12 cm, it can be planted. After 20 days of planting, the heart was picked for the first time. When the plant height was 30 cm, the net support was set up to keep the flower stem straight and straight. Generally, only one flower was left at the top, fertilized once a week during the growing period, cut when the bud was dewy, and the cut flowers should be put on the market in time and stored in a low temperature environment of about 4 ℃.

Carnation is the most suitable for cutting propagation. The time of cutting is unlimited, except for the too hot climate, it can reproduce in other seasons. Among them, the survival rate of cuttage in early February was the highest. The following editor would like to introduce the cutting methods of carnations.

1. The establishment of the mother garden of ear picking. The practice shows that the necessary conditions for the mother plant of panicle harvesting are: the relative age of the plant is young, the flowering character is good, the disease index is zero, and the panicle position should be strictly controlled above the 6th node. Therefore, the establishment of a dedicated spike-picking mother garden is very necessary and critical, and it is also an indispensable link in the process of modern carnation seedling production. It is not only the premise of forming high-quality seedlings, but also the basis of large-scale seedling raising throughout the year.

The mother plant of panicle picking mother garden must be tissue culture seedlings. The key to the cultivation and management of the mother garden is to strengthen soil disinfection, advocate crop rotation, ensure the application of adequate base fertilizer, shelter rain and shade measures, advocate drip irrigation, and do a good job in the prevention and control of diseases and insect pests.

2. Cutting technology.

Selection of ⑴ cuttings. Select pest-free, robust growth, close internodes of the plant, and have 3murmur4 pairs of unfolded leaves, 1 pair of unexpanded leaves, population cuttings with flower bud rate less than 10%.

⑵ cutting time. Generally, we should avoid the hot summer from July to August, require good cutting quality, use perlite with larger particles as the cutting parent material, good water quality, and the cutting bed is a table.

Adoption and cuttage of ⑶ cuttings. The adoption of cuttings is generally carried out at the same time as the sprouting of carnations. Cuttings should be picked according to the standard, and sprouts should be broken by hand instead of scissors to avoid virus cross-infection. There should be a slight trunk cortex at the base, but the mother branch should not be damaged, and the top leaves of cuttings should be retained for 5 pieces, and the rest of them should be removed. After finishing into bundles, soak in water for 30 minutes to make the cuttings absorb enough water. The section should be close to the internodes and treated with growth regulators in order to improve the survival rate and emergence rate. When cutting, it is appropriate to insert 1 cm of medium. Insert deeply in summer, usually 1.5-2 cm. After cutting to spray enough water, later control should not be too wet, so as not to rot the root.

Storage of ⑷ cuttings. Storing cuttings can not only provide great convenience for raising seedlings and balanced flower supply throughout the year, but also can carry out batch operation at one time and save manpower and material resources. Storage requirements: temperature 1 ℃ 2 min, and the smaller the range, the better, preferably within ±1 ℃; slightly dehydrated before storage; cuttings packed with ultra-thin plastic film.

⑸ cuttage management. The slotting machine should have intermittent spraying facilities, and the amount of spray should be controlled to make the blade just wet. If there is no spray, cover the plastic film and use the Reed curtain after 1 week, but do not block too much light to prevent overgrowth. Transplant when the root of the cuttage is 1 cm long, pay attention to less root damage.
