How to manage cucumber seedlings? 40

Seedling management: after sowing to before the cotyledons are unearthed, 25-30 during the day, about 20 at night, about 25 during the day after the seedlings are unearthed, about 16 at night, about 4-5 days after sowing, when the cotyledons turn green, the temperature after transplanting seedlings is 25-30, 3-4 days after the seedlings, the bed temperature is 20-25 during the day, and 14-16 at night.

Cucumber (scientific name: cucumissativusl.).Cucurbitaceae is an annual creeping or climbing herb. The stems and branches are elongated, furrowed, and covered with white rough bristles.

1. After selecting the cucumber planting plot, the main fertilizers include well-rotted organic fertilizer, urea, calcium, and potassium fertilizer.

2. Before planting, use appropriate fungicides to sterilize the plot, ditch and water on the ridge, and then put the seedlings according to a reasonable spacing, seal the ditch after water infiltration, plant about 3,500 plants per mu, and buckle the small arch shed on the furrow after planting.

3. After planting, the temperature needs to be controlled at 21-28, and the minimum temperature at night is maintained at about 12. to promote the slow seedling as soon as possible.

4. After the cucumber is planted, it is necessary to water the seedlings once, when the cucumber begins to set melons, it is necessary to water the second time, after entering the melon setting period, the water demand increases, and the watering interval should be adjusted due to factors such as growth and weather, and the melon setting period, pay attention to increasing the application of urea and potassium sulfate, which can quickly improve the yield of cucumbers.

5. When the plant grows to 7-8 leaves, the plant height is about 25 cm, remove the small arch shed, start the rope, the side vines below the first melon should be removed as soon as possible, and leave 2 leaves before the melon topping. When the main vine grows to 25 leaves, the topping is carried out to promote the growth of back melon, and the root melon should be picked in time to avoid falling seedlings.

6. In the process of cucumber planting, aphids, downy mildew and other pests and diseases are prone to occur, and 10% imidacloprid can be used to spray to prevent and control aphids, and ethylphosphine aluminum wettable powder solution can be sprayed to prevent and control downy mildew.

<> management of cucumber seedlings, to do a good job of temperature control measures, let it grow in a warm environment, seedlings should be planted at low temperature before the seedlings are planted, during the day, the cucumber seedlings need to have sufficient light, in order to facilitate its photosynthesis, at this time, it is also necessary to let the cucumber seedlings have sufficient water and fertilizer, so that it can grow vigorously.

1. Suitable temperature.

The management of cucumber seedlings, need to let it have a suitable temperature, in order to prevent it from the phenomenon of tall seedlings, the seedling period during the day temperature control between 25-30 is the best, at night, the temperature of Lingli is controlled at about 15, before planting, it is also necessary to practice seedlings at low temperature, so that cucumber seedlings can grow healthily after that.

2. Sufficient light.

The growth of cucumber seedlings needs sufficient light, so the management of cucumber seedlings, during the day, to let them have the light that is full of celery, so that cucumber seedlings can grow more robust, rainy weather to be artificial for it in time, but in summer, pay attention to avoid it being exposed to strong light.

3. Moisture requirements.

Cucumber seedlings for the demand for water is relatively high, in the management process, we need to often observe the dryness and humidity of the seedbed soil, if there is a lack of water, it is necessary to replenish water in time, otherwise the water is insufficient, cucumber seedlings are easy to wither, but to avoid the soil has water accumulation, so as not to appear rooting phenomenon.

4. Sufficient nutrients.

Cucumber seedlings need sufficient nutrients to grow, so when we are in management, we can spray a foliar fertilizer for them to promote its vigorous growth, pay attention to the fertilization to master the principle of thin fertilizer diligently, not to apply thick fertilizer to cucumber seedlings, otherwise it is easy to cause cucumber seedlings to burn.

Management cucumber seedlings, to do a good job of temperature control measures, let it grow in a warm environment, seedlings before planting seedlings at low temperature training, during the day, need to let cucumber seedlings have enough light, in order to facilitate its photosynthesis, then also need to let cucumber seedlings have sufficient water and fertilizer, so that it can grow vigorously.

1. Suitable temperature.

The management of cucumber seedlings, need to let it have a suitable temperature, in order to prevent it from the phenomenon of tall seedlings, the seedling period during the day temperature control between 25-30 is the best, at night, the temperature is controlled at about 15, before planting, it is also necessary to train seedlings at low temperature, so that cucumber seedlings can grow healthily after that.

2. Sufficient light.

The growth of cucumber seedlings needs sufficient light, so the management of cucumber seedlings, in the daytime, to let them have sufficient light, so that cucumber seedlings can grow more robust, rainy weather to be artificial light for it in time, but in summer, pay attention to avoid it being exposed to strong light.

3. Moisture requirements.

Cucumber seedlings for the demand for water is relatively high, in the management process, we need to often observe the dryness and humidity of the seedbed soil, if there is a lack of water, it is necessary to replenish water in time, otherwise the water is insufficient, cucumber seedlings are easy to wither, but to avoid the soil has water accumulation, so as not to appear rooting phenomenon.

4. Sufficient nutrients.

Cucumber seedlings need sufficient nutrients to grow, so we dig in the management, you can spray a foliar fertilizer for it, in order to promote it to grow vigorously, pay attention to fertilization to master the principle of thin fertilizer diligently, can not apply thick fertilizer to cucumber seedlings, otherwise it is easy to cause cucumber seedlings to burn the phenomenon.

1. Fertilization and land preparation: select the field that has not been planted with crops in 2-3 years, apply well-rotted manure, and turn it over. 2. Heqing Bili planting:

Dig a furrow in the soil and plant the seedlings in a furrow. 3. Top dressing and watering: apply 5 kg of urea and compound fertilizer per mu, and water more on sunny days.

4. Build a bamboo shed: insert bamboo chips next to the seedlings to make the stems and vines climb and grow.

1. Fertilize and prepare the land

In order to make cucumber seedlings grow robustly, in the planting process, it is necessary to select fields that have not been planted with crops in the past 2-3 years, apply the rotted farmhouse fertilizer, turn it with a machine, and then dry the soil for 1-2 days to prevent cucumber seedlings from being infected with diseases.

2. Reasonable planting

When planting cucumber seedlings, you should first dig a ditch in the soil to keep the depth of the ditch at about 10 cm, and then plant the seedlings neatly in the ditch and cover with a thin layer of soil.

3. Top dressing and watering key tombs

Cucumber seedlings grow stable after a top dressing, apply 5 kg of urea and organic fertilizer per mu, it is best to apply Queliangqin fertilizer after rain, can achieve the effect of strong seedlings, and when the weather is fine, to water cucumber seedlings, so that the soil remains moist.

4. Build a bamboo shed

When the cucumber grows to about 50 centimeters, it is necessary to build a shed, and the melon shed is generally built with wood chips and bamboo poles, and a door-shaped arch shed is built, and the wooden chips are made into a bracket and inserted into the soil for 30 cm, plus the bamboo pole is solid, so that the cucumber climbs and grows.

Cucumbers are typical of temperature-loving plants, and the suitable temperature for seedlings is 10 to 32 degrees Celsius. Cucumbers have a higher temperature requirement of about 25 to 32 degrees Celsius during the day and a lower temperature requirement of about 15 to 18 degrees Celsius at night. The appropriate temperature for photosynthesis is 25 to 32 degrees Celsius.

The temperature of cucumbers is controlled at 30 to 32 degrees Celsius before emergence, and most of them drop to 20 to 25 degrees Celsius, and the temperature is controlled at about 28 degrees Celsius when the true leaves are exposed.

Spring cucumbers are grown after the late frost in the local area, with an average temperature of more than 18 degrees Celsius.

Autumn cucumber seedlings are only in frost areas refers to the cultivation of the harvest before the first frost, and in the perennial frost-free areas are the cucumbers that are marketed in the autumn when the summer cucumber seedlings are pulled, and the growth period of autumn cucumbers is only 80 to 90 days, which can be cultivated directly, or transplanted seedlings, and produced in open fields or greenhouses.

Before the seedlings are raised in winter, water the bottom of the foot first, and then plant with some water when the ground temperature rises and the weather is fine. Winter watering is based on the principle of frequent watering of small water under the film, and watering should be avoided during the severe cold period and continuous cooling and snowy weather, so as to be dry rather than wet. Direct irrigation of the river is strictly forbidden in winter.

The management method of growing cucumbers mainly needs to consider these aspects:

1. Sow and plant.

Cucumbers can be planted by sowing seeds. First of all, you need to select the seeds with full particles, then you can soak the seeds in warm water to disinfect, take them out and drain them after half an hour, and evenly sow them in fertile and loose soil with good drainage.

2. Provide moisture.

Cucumber in the process of growing the demand for water is larger, in the process of maintenance, it needs to be watered every five days to keep the soil in a moist state, in the summer when the temperature is higher, it needs to be watered once a day to maintain the normal growth of cucumber, in the watering, it is best to use non-polluted river water.

3. Supplement nutrients.

Cucumber is suitable for growing in a more fertile environment, in the process of maintenance, it can also provide nutrients for the plant to provide nutritionally balanced inorganic fertilizer, improve the growth rate of cucumber, can also provide it with well-rotted organic fertilizer, so that the plant grows more vigorously, in the fertilization, you need to pay attention to the amount of fertilizer, so as to avoid fertilizer damage to the plant.

1. Seed treatment Seed disinfection should be carried out before sowing to prevent seeds from carrying bacteria. The seeds can be soaked in 50 55 hot water for 15 minutes or 50% carbendazim 500 times solution for 20 minutes. When soaking seeds in hot water, keep stirring to prevent the seeds from being scalded by hot water, then rinse them with clean water, and then soak them in natural water temperature for 3 4 hours, take them out and dry them for sowing.

2. After sowing the seeds, the germination treatment is carried out under 25, and when 80% of the seeds are white, they can be sown. When sowing, the seedling tray can be loaded with nutrient soil, or the seedbed can be used for direct seeding. The seedbed should be disinfected with carbendazim 500 times.

3. Seedbed management After sowing, the daytime temperature is controlled at 25 28, and the night is not less than 20, and the seedlings can emerge in 3 4 days. From the seedling unearthing to the first true leaf before the first leaf is issued, the temperature should be appropriately reduced, to 23 25 during the day and 13 15 at night, to maintain a large temperature difference between day and night to prevent the seedling from growing. If it is a seedbed seedbed, it is necessary to divide the seedlings, water enough, and after the seedlings are slowed down, the bed temperature should be gradually reduced, and the temperature difference between day and night should be increased to facilitate the cultivation of strong seedlings.

7 to 10 days before planting, the seedlings should be exercised at low temperature to adapt to the environment of low temperature and large temperature difference in early spring of plastic greenhouse.

The management methods of cucumber seedlings after transplanting include root promotion, seedling control and top dressing management.

1. Promote root control and seedling control.

In order to promote the slow seedling within one week after planting, the day is 25 32 and the night is 15 17. After slowing the seedlings, the air volume should be increased, the maximum noon on a sunny day should not exceed 30, 15 12 at night, and 10 before the curtain was unveiled in the morning, so as to increase the temperature difference between day and night and control the growth of the aboveground. If the temperature management is too high, the plant will grow too vigorously and will not be able to land until the coldest months to resist the cold snap.

2. Top dressing management.

With the increase in the amount of melon picked, timely nutrition is supplemented. According to the harvest amount and plant performance, determine the type and quantity of top dressing, generally at the beginning of the fourth water with water top dressing, if the leaves, melon strips are darker in color, top dressing is mainly nitrogen fertilizer, phosphorus and potassium fertilizer is supplemented, and pay attention to the supplement of calcium, magnesium and other trace elements. When applying, the fertilizer is dissolved first and top dressing with water.

The amount of top dressing should follow the criterion of "thin fertilizer and diligent application" to prevent excessive amount of top dressing at one time. After March, watering can be separated and top-applied dilute manure and biogas slurry and digestate residue.

Daily cultivation and management techniques of cucumbers

1. Planting time.

Cucumbers can be planted in February and March in spring, August and September in autumn, and May and June in summer, cucumbers are suitable for growing in a warm environment, and can be sown in April and May every year, during which the temperature is stable at more than 15.

2. Seedling transplanting.

When the ground temperature is stable above 15, seedlings can be transplanted, seedlings are transplanted at low temperature for about 10 days before transplanting, and transplanting is carried out after 4 o'clock in the morning or afternoon on a sunny day.

3. Reasonable watering.

After transplanting, if the base fertilizer is sufficient, there is no need to supplement water and fertilizer, as long as the soil is kept dry and wet. When the root melon grows to more than 10 cm, it can be watered for the first time, generally speaking, the cucumber is watered once a week before harvesting, watered once every 4 days during the peak period of melon picking, and watered once a week in the later period.
