Is there a process for raising cucumber seedlings, and how to raise cucumber seedlings?

1) Soaking and disinfection: In order to promote germination and kill the germs or viruses carried by the seeds, seed disinfection and soaking are often carried out. The more commonly used is the warm soup soaking method, that is, the first 50 55 hot water soaking seeds for 15 minutes, the amount of hot water is about 5 times the amount of seeds, and the seeds should be constantly stirred during hot water treatment to make them evenly heated.

Then soak the seeds at room temperature for about 4 hours. A certain high temperature is conducive to killing the germs carried by the seeds, and at the same time, it can promote the seeds to absorb water and swell and germinate early. Soak the seeds with clean water and containers, and at the same time, knead the seeds in combination with the soaking, wash the mucilage on the seed coat, rinse off the seeds, and remove impurities.

Seeds can also be sterilized in combination with other treatments after or during soaking. For example, cucumber seeds soaked with potassium permanganate can be treated, and the seeds are soaked with potassium permanganate for 30 to 60 minutes to kill the germs on the surface of the seeds, and washed after soaking for germination. It can also be disinfected with pesticides, such as soaking seeds at room temperature for 4 hours with 600 times of 50% carbendazim wettable powder.

2) Germination: The seeds that have been sterilized and soaked are placed under suitable temperature and humidity conditions to promote the rapid germination of cucumber seeds, and then sow with germinated seeds. The suitable temperature for cucumber seed germination is 28 29, and at this temperature a certain humidity is maintained, and germination can be achieved in about 1 2 days.

Various methods can be used to achieve the optimal germination temperature of the above-mentioned cucumber during specific germination. Conditionally, you can use a constant temperature incubator for constant temperature germination, wrap the soaked seeds with a damp cloth, and put them into the 28 29 constant temperature box, this method is fast and neat, but you need to buy a constant temperature box.

3) Low temperature treatment and cold resistance exercise: the seeds that start to germinate after soaking and swelling, and the radicle has not yet emerged are placed under 0 for 1 2 days, or at a low temperature of -1 2 for 2 4 hours, and then placed in cold water to slowly heat up and then germinate. After this treatment, the low temperature tolerance of cucumber seedlings can be improved2.

4) Seed dosage: cucumber 50 grams of seeds about 2000 seeds, in addition to the seeds and considering the seedling preservation rate in the seedlings, generally 50 grams of seeds can get about 1500 seedlings, planting 1 acre of cucumber about 200 grams of high-quality cucumber seeds.

The method of cucumber seedling raising is as follows:

Greenhouse seedlings are mainly cultivated in cold winter or early spring for solar greenhouse winter and spring stubble, early spring stubble cucumber cultivation, and spring protection of rehmannia socks curcumber cultivation seedlings.

Greenhouse and cold bed supporting seedling cultivation This method is to sow and raise seedlings in the greenhouse, and then plant them in the cold bed or plastic small arch shed to cultivate seedlings.

The seedling standard of cucumber is as follows: the seedling internode is short, the stem is thick, the bristles are hard, the stem transverse diameter is between o 6 0 8 centimeters, and the plant height is less than 10 cm; The leaves are flattened, thick, dark green in color, up to 3 leaves with 1 heart or 4 leaves with 1 heart; cotyledons intact, fat, shiny; The root system is well-developed and white; No pests and diseases, strong vitality; The general calendar is 30 to 40 days old; After planting, it has the characteristics of slow seedling and fast rooting, strong cold resistance, many female flowers and low nodes, early maturity and high yield.

Cucumber Cucurbitaceae is an annual creeping or climbing herb. The stems and branches are elongated, furrowed, and covered with white rough bristles. The tendrils are thin.

petioles slightly rough, with rough bristles; Leaves broadly ovate-heart-shaped, membranous, lobes triangular, toothed. Monoecious. Male flowers:

constant flowers are clustered in leaf axils; peduncles slender, slightly pubescent; The corolla is yellowish-white, and the corolla lobes are oblong-lanceolate. Female flowers: solitary or sparsely clustered; peduncle stout, pubescent; The ovary is rough.

The fruit is oblong or cylindrical, yellow-green when ripe, and has a rough surface. Seeds are small, narrowly ovate, white, without edges, and nearly acute at both ends. Flowering and fruiting period in summer.

The whole process of cucumber seedling: seed selection, seedling raising, and temperature management.

1. Select seeds: Select seeds to ensure high quality, classify seeds, and pick out shriveled and damaged seeds. Soak the seeds in boiling water, maintain a temperature of more than 55 degrees, pick them up after about half an hour, wash them with warm water, soak them in cold water for 6-8 hours, and then wrap them in wet gauze and put them in a natural environment of 25-30 degrees to germinate, and there will be white leakage after 2-3 days, and then you can sow seeds.

<>3, temperature management: after sowing the temperature of the seedling room should be controlled around 32, generally 3 days after sowing there are 1 3 seedlings, when the seedlings reach 70% when the temperature drops to 18-22, to avoid high temperature weather caused by seedlings. More than 10 days of seedlings must be divided in time, which is beneficial to the growth and development of cucumber seedlings.

The environment in which cucumbers are grown

1. Temperature: Cucumbers like warmth and are not tolerant to cold. The fertility temperature is 10 32.

Generally, 25 32 during the day and 15 18 at night grow best; The most suitable ground temperature is 20 25, and the lowest is about 15. The optimal temperature difference between day and night is 10 15.

2. Light: North China varieties are not strict on the length of sunshine, and have become sunshine neutral plants, with a light saturation point of 10,000 lux and a light compensation point of 1500 lux, and most varieties grow well under the condition of 8 11 hours of short sunshine.

3. Moisture: cucumber has a high yield and a large water requirement. The suitable soil moisture is 60% 90%, the water at the seedling stage should not be too much, the soil moisture is 60% 70%, and sufficient water must be supplied in the fruiting period, and the soil moisture is 80% 90%.

The suitable air relative humidity for cucumbers is 60% to 90%.

The whole process of cucumber seedling raising: soaking, teething, field selection, transplanting, etc.

Soaking: Put the dried cucumber seeds in hot water of 55-60 degrees, and soak the seeds in water. Stir constantly to heat the seeds evenly so that the viability of the seeds is not reduced due to the high temperature of the water.

After soaking for 10 minutes, stop stirring when the water temperature drops to 25, and soak for another 4-6 hours.

Teething: Finally, wash the gel on the surface of the seeds, wrap them in a clean towel and place them at room temperature of 25 °C to germinate. Generally, it takes 1-2 days to bud.

Field selection: The seedling substrate needs to choose the large garden soil without heavy stubble, and it is the most seedling soil after mixing with organic fertilizer, plant ash, etc. After sowing the seeds, cover with a thin layer of soil. The room temperature is kept at around 25 degrees Celsius.

Transplanting: Seedlings need to be divided in time for about ten days, which is conducive to the growth of cucumber seedlings. Generally, cucumber seedlings can be transplanted when they have grown to four to six true leaves.

Precautions after transplanting cucumbers

After transplanting, the growth rate of cucumber seedlings is relatively fast, cucumber seedlings begin to shake the vine after planting slow seedlings, and begin to enter the early flowering stage, the management of cucumber seedlings at this time needs to pay attention to the growth of the root system, this stage is mainly based on vegetative growth, and the later stage begins to change to reproductive growth. It is best to keep the humidity in the greenhouse at about 90% during the seedling stage after planting, and the temperature is controlled at about 28 degrees to 30 degrees during the day and 15 to 18 degrees at night.

When raising cucumber seedlings, you need to soak the seeds in warm water at 30 degrees for 4-5 hours, then sow the cucumber seeds into loose and fertile soil, and then build a cold shed on the soil to keep the environment at about 25 degrees, and after the cucumber grows 2-3 true leaves, it can be transplanted into the soil.

1. Seed treatment

When planting cucumbers, you need to choose seeds with full particles and no pests, and then soak them in warm water for a period of time, so that the seeds can absorb enough water to break the dormant period of the plant, and the cucumber seeds should be placed in an environment with a temperature of about 25 degrees for germination, and wait for them to be white before sowing.

2. Seedling raising method

When raising cucumber seedlings, it is necessary to apply well-rotted horse manure to the soil to improve the fertility of the soil, and then sow the cucumber seeds into the soil, and then water it once to keep the soil moist, and build a cold shed on the soil to make the ambient temperature constant and promote the rapid emergence of cucumber seedlings.

3. Planting method

When planting cucumbers, you need to choose loose, fertile and well-drained soil for them, then apply superphosphate and organic fertilizer to the soil, and then transplant cucumber seedlings into the soil, and build cuttings about 8-10 cm at the root of cucumbers, which is conducive to the growth of cucumber branches.

4. Maintenance management

When maintaining cucumbers, it is necessary to prune the branches of the plant regularly, and the side branches that grow too much in the cucumber can be cut off, so that the nutrients are concentrated in the main branch, and the main branch is promoted to bear fruit quickly, and during the cucumber bud pregnancy period, it is necessary to spray foliar fertilizers such as potassium dihydrogen phosphate on its flowers and leaves, so that the number of fruits of the plant increases.

<> cultivating yellow flower seedlings, you need to soak the seeds in warm water first, and then carry out germination, the seedling soil requires loose ventilation and good drainage, after filling the soil into the seedling hole, you can sow the seeds after germination, do a good job of heat preservation and moisturizing, and soon the seeds can emerge, and you can transplant and plant when there are 3-4 true leaves.

1. Seed treatment

To cultivate cucumber seedlings, it is best to soak the seeds in warm water for half an hour, and then soak them in water for 6-8 hours to make the seeds absorb enough water, and then put them in a wet cloth to promote germination in the environment of 26-30 after the reincarnation, and wait until the seeds are white and can be sown.

2. Soil requirements.

When cultivating cucumber seedlings, the pre-Yukon seedling soil requirements are loose, breathable and well-drained type, we can use peat, perlite and vermiculite according to the ratio of 2:1:1 mixed preparation, after the soil is prepared, you can fill it into the seedling hole, and then water thoroughly to make the soil in a slightly moist state.

3. Sowing and planting.

Sow the germinated seeds into the seedling hole, and cover with a thin layer of soil, and then you can cover it with a layer of plastic film, which can play the role of heat preservation and moisturizing, the temperature is controlled at about 25 is more suitable, and soon the cucumber seeds can emerge and grow.

4. Cultivation and maintenance.

After the cucumber seeds emerge, the plastic film should be removed in time, during which the ventilation management should be strengthened, and the soil should be kept slightly moist, when the seedlings grow, they can be sprayed with diwax phosphate potassium hydrogen potassium solution for top dressing, and the seedlings can be transplanted and planted after 3-4 true leaves.
