How to raise cucumber seedlings, how to raise cucumber seedlings

Seed disinfection is carried out first, and the method is simple and easy to use hot water to blanch seeds, and the bactericidal power is strong.

Put the seeds into a container of 1 part of cold water, and then slowly add 2 parts of boiling water and stir constantly, the temperature can reach 52-55, and keep for 15 minutes. After dropping to 30, rub off the mucilage on the seeds, rinse and soak for 6 hours to induce germination.

Sprouts overnight. Half of the fully developed horse manure, pigsty manure, and chicken manure are mixed, half of the fertile field soil is added, and the seedbed nutrient bowl fertilizer (1 kg 3000 bowls) is added, and the nutrient soil is sieved after mixing.

Fill 8 10 cm bowls and do not overfill.

Put a white seed flat in the nutrient bowl, do not insert it in the soil, cover it with a centimeter thick nutrient soil, cover it with plastic film to keep it moist after sowing, and insert a thermometer in the middle of the seedbed to observe the soil temperature.

When the day is more than 30, be sure to uncover the mulch film to prevent the high temperature from burning the seed buds, and cover the mulch film in the evening. In this way, the seedlings will be ready in a few days. Beans live broadcast is fine. The seedlings are 30 days old in the spring shed, and the water must be controlled to prevent growth.

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.

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%.
