The method of sowing and raising seedlings of Cymbidium

It takes 8 to 10 months from flowering and fruiting to seed maturity. Its sign is that the skin of the fruit has gradually changed from green to red or brownish red, when the seeds in the fruit have also matured and should be harvested in time. Seed selection is carried out at the same time of peeling seeds, and it is found that stunted or shriveled seeds should be eliminated. Put the selected mature and well-developed varieties into a gauze bag, hang a label, register the variety name or code name, and wait for sowing.

The sowing time is mostly between November and February of the following year. Seeds are usually sown in shallow pots or wooden boxes, and the substrate can be evenly mixed with clean river sand or 2 parts of river sand and 1 part of horse dung soil, and conditionally disinfected with formalin (40% formaldehyde solution). Put the treated substrate into a seedling basin or box, scrape it flat with a board, and then sow seeds. When sowing, arrange the seed holes down on the sand in the seedling basin or box, about 2 cm apart.

After sowing, cover the seeds with a layer of river sand, which is thick enough to cover the seeds. Then pour through the water, put the seedling urn or box on the radiator or Kang, but the bottom of the basin or box should be covered with a thick plank to avoid excessive temperature scalding the seeds. The seed germination temperature should be controlled at 20-25 ℃, and the substrate should be kept moist. In order to reduce the evaporation of water in the seedling basin or box, cover the seeding container with a piece of glass so that it can be watered every 3 to 5 days, and be sure to water thoroughly each time.

Generally speaking, radicles can grow in 10-15 days from the date of sowing. The coleoptile grew after 40 days. Coleoptile is the first cone-shaped sleeve, which can protect the young and young leaves of the germ from damage when they are unearthed. According to research, coleoptile contains plant growth hormone, which plays an important role in the growth of seedlings and seedlings.

About 50 days after sowing, the seed grows the first leaf, when the plant begins to grow and develop itself, and when the first leaf grows out of coleoptile, it can carry out photosynthesis. With the gradual growth of seedlings, the seedlings should be divided in time according to the growth of their leaves. When dividing the seedlings, the seedlings should be selected, the seedlings with poor growth potential should be cultivated separately, the seedlings with no cultivation value should be eliminated, and the seedlings with exuberant growth should be cultivated together.

The nutrient soil for seedling separation is made up of 70% rotten horse dung soil or forest humus soil mixed with 30% river sand. The young plants are very small and can be planted in a flowerpot every 5-6 or every 10. When transplanting, the front of the seedling leaves should be facing in one direction, and do not plant randomly. After transplanting, it should be watered thoroughly, then moved to the appropriate position, and the leaves should be placed facing the sun.

After the seedlings were transplanted, they entered the seedling stage management. The quality of management at seedling stage directly affects the vegetative growth and reproductive growth of plants. The growth temperature of the seedling stage should be controlled at 10: 20 ℃, the maximum should not exceed 25 ℃, and pay attention to ventilation, and the water content should be controlled at 20% 30%. In summer, due to the hot weather, large water evaporation, nutritious soil is easy to drought. Generally, it needs to be watered once a day; in cloudy and rainy days, the amount of water evaporation is small, so it can be watered once every 3 days. When watering, be sure to water thoroughly.

Fertilization at seedling stage should be properly applied with thin cake fertilizer and water according to the growth and development of the plant. Under normal circumstances, it is applied every 10 to 15 days. When applying liquid fertilizer, be careful not to drop on the leaves or pseudo-bulbs, otherwise dripping on the leaves will burn the leaves, dripping into the false bulbs will burn the whole plant. If you drop it inadvertently, you must rinse it with clean water immediately.

Sowing and Seedling raising of Cymbidium

It takes 8 to 10 months from flowering and fruiting to seed maturity. Its sign is that the skin of the fruit has gradually changed from green to red or brownish red, when the seeds in the fruit have also matured and should be harvested in time. Seed selection is carried out at the same time of peeling seeds, and it is found that stunted or shriveled seeds should be eliminated. Put the selected mature and normal varieties into a gauze bag, hang a label, and log in the variety name or code name. To be sown.

The sowing time is mostly between November and February of the following year. Usually sow seeds in shallow pots or wooden boxes, and the substrate can be evenly mixed with clean river sand or 2 parts of river sand and 1 part of horse dung soil, and conditionally disinfected with formalin (40% formic acid solution). Put the treated substrate into a seedling basin or box, scrape it flat with a board, and then sow seeds. When sowing, arrange the seed holes down on the sand in the seedling basin or box, about 2 cm apart.

After sowing, cover the seeds with a layer of river sand, which is thick enough to cover the seeds, then pour water thoroughly, move the seedling basin or box to the radiator or fire pit, but cover the bottom of the basin or box with a thick plank to avoid excessive temperature scalding the seeds. The seed germination temperature should be controlled at 20-25 degrees, and the substrate should be kept moist. In order to reduce the evaporation of water in the seedling basin or box, the seeding container can be covered with glass, so that it can be watered once every 3-5 days and must be watered thoroughly each time.

Generally speaking, radicles can grow after 10 to 15 days from the date of sowing. The coleoptile grows after about 30-40 days. Coleoptile is the first cone-shaped sleeve, which can protect the young and young leaves of the germ from damage when unearthed. According to the study, coleoptile contains plant growth hormone, which plays an important role in the growth of seedlings and seedlings.

How to sow and raise seedlings of Cymbidium? Sowing and raising seedlings is the main method of breeding Cymbidium, which has a large reproduction quantity and is generally not different from the mother plant. Magnolia usually blossoms in February-May and ripens in 7-10 months. When the fruit changes from green to purplish red, the fruit ripens. At this time, the fruit can be cut off, cut open to take out the seed and sow immediately. Sowing too late will affect seedling emergence. The sowing soil can be made with fertile garden soil, 5 parts of rotten leaf soil and 5 parts of sand. Pure sand is lack of nourishment, so pure sand is generally not used to raise seedlings. When sowing, first spread a layer of broken rubble at the bottom of the basin to facilitate ventilation and water penetration. Fill it with basin soil. The basin soil is slightly compacted and can be sown after leveling. The seeds of Cymbidium are large and should be sowed on demand, with a distance of about 5 cm. The soil on the seed is 1-1.5 cm. Water thoroughly after sowing, put it indoors and keep it moist. When the room temperature is about 20 ℃, the seedlings can emerge in 40-50 days. When the room temperature is above 15 ℃, it will take 60-90 days to emerge. After emergence, the seedlings were cultured in a soft place in the sun, dry watering, keeping the soil slightly moist and keeping the room temperature between 18-22 ℃. When there are 2 leaves, they can be cultured in pots.
