Carnation planting

Carnation planting

The reproduction of carnations can be divided into asexual reproduction and sexual reproduction. To propagate with seeds or strips.

Sexual reproduction: sexual reproduction tends to have low seed setting rate, large variation of seed progeny characters and slow seedling growth, so it is less used in production. Asexual reproduction is widely used in production, which is mainly cuttage propagation, which has the advantages of rich cuttings, stable characters and quick effect.

The establishment of the mother garden of picking ears. 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.

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

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

Take cuttings with 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. 4-5 top leaves of the cuttings should be retained and the rest 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 inserting, it is appropriate to insert the media 1 inch meter. It should be cut deep in summer, usually 1.5 to 2 centimeters. Spray enough water after insertion, and control should not be too wet in the future, so as to avoid rotting roots.

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: the temperature is 1: 2 ℃, and the smaller the range, the better, preferably less than ±1 ℃; slightly dehydrated before storage; cuttings are packed with ultra-thin plastic film.

⑸ plug-in 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 cuttings is 1 meter long, and pay attention to less root damage.

Potted plant

Carnations are mainly propagated by seeds and cuttings. The suitable temperature for seed sowing and germination is 20 ℃, and the time for seed germination is longer, which takes 10 to 15 days. It could not blossom until 140 ~ 160 days after sowing, and the optimum temperature for plant growth was 5 ~ 20 ℃. When the temperature was higher than 30 ℃, the plant stopped growing and even died. Therefore, it should be cultivated in winter and spring in South China. During the Spring Festival flowering production, sowing and cultivation should be carried out in cool areas (high mountains) from August to early September.

Carnation pot substrate requires good drainage and rich in organic matter, and the cultivation environment requires plenty of sunshine. If the temperature is too high or the light is not enough, the plant is easy to grow, the branch is slender, the plant type is poor, and it is not easy to bloom.
