Is it better to sow lettuce directly or to plant seedlings? How do I raise seedlings?

Lettuce sowing and seedling transplanting can be done, but the seedling transplanting effect is better. The seeds are soaked in water overnight before planting, then filtered out and wrapped in sterile gauze. Place it at 18-20 degrees to carry out tooth promotion, and see the buds gradually budding, and then you can plant.

Sprinkle the seed buds evenly on the surface of the soil layer, and sprinkle a thin layer of soil on the top, which can cover the seeds, and the soil should not be too thick, which will harm the germination rate. When transplanting lettuce seedlings, it is more convenient in supervision, as long as the time constant is good, the seedlings will grow and develop neatly, which is conducive to fertilizer and water management in the middle and late stages.

Lettuce prefers shade and natural environment, is neither tolerant to low temperatures nor heat, and rises well in conditions of 15 to 20 degrees. The ambient temperature of seed germination is good at 18 to 22 degrees, and germination is almost non-germinating at temperatures above 30 degrees. Lettuce can be grown in greenhouses all year round, and open field cultivation is good in spring and autumn, but when planting in summer, you need to pay attention to shading and temperature reduction to ensure that lettuce sprouts.

We select the local suitable species in the variety, and then apply organic fertilizer and compound fertilizer to the side of the seedbed, and evenly apply it to the side of the seedbed. Water the soles of your feet and wait for the water to seep into the plant.

When planting lettuce immediately, the consumption of seeds is large, and lettuce seeds** are more expensive, and the cost of seeds will increase. On the other hand, when sowing seeds and planting immediately, the seedling replenishment work also needs a relatively large amount of manpower expenditure, and can not ensure the consistency of lettuce growth and development, the vegetables and fruits cultivated are some large, some are small, and the management method and picking inconsistency of lettuce in the middle and late stages are not easy to manipulate. The method of immediately sowing seeds and planting lettuce is suitable for the characteristics of reduced planting amount, small scale, and eating and picking in small rural vegetable gardens.

Lettuce seeds are more subtle, and seedling transplanting is beneficial to improve germination rate, cultivate vigorous seedlings, and maximize profits to save seeds. In addition, the general seedling transplanting method to carry out planting, lettuce seedling period and late management methods, lettuce growth and development convergence is very high, is conducive to the unified control and management methods of lettuce planting, lettuce quality and production is also higher, is conducive to large-scale industrial manufacturing. The planting method of transplanting after seedlings, lettuce growth and development are relatively high, which is suitable for lettuce planting with a relatively large total area and industrialization.

Under normal circumstances, they are planted directly from seeds, and it is necessary to pay attention to the temperature and the surrounding environment when raising seedlings.

It must be the best thing to plant seedlings to promote growth. It needs to be planted in a warm environment first, and it is necessary to fertilize and water it in time to ensure growth.

Of course, it is better to plant seedlings directly, because such lettuce is relatively green, you can choose to plant the seeds in the right soil, and when the seedlings grow, water them frequently.

Both have their own advantages and disadvantages, and the best way to grow them is the one that suits you.

It's better to sow seeds directly. The direct sowing and planting method saves a lot of labor and time. However, lettuce seeds themselves are expensive, and the method of sowing seeds over a large area will inevitably increase the cost of planting.

In addition, sowing seeds does not guarantee uniform seed germination and growth. In the later stage, lettuce is large and small, and the growth is not easy to control. Therefore, seedling transplanting can provide a better growth environment for seeds.

It is best to choose sowing seeds, which can reduce costs and will be very trouble-free. The survival rate of lettuce is still relatively high.

The method of growing lettuce is relatively simple, and the requirements for the soil environment are not so strict. When planting lettuce, I don't know whether to use direct sowing or seedling planting, but in fact, both have their own advantages. If you plant a small area, you can use both methods, and the difference is not that big.

When planting large areas, it is important to use labor to maintain yield and quality. You can choose to fix the value first and then spread it. Choose different sowing methods according to different conditions, so as to ensure that lettuce can grow well.

The sown seeds are relatively small, and when the seeds are sown, they tend to form clumps, that is, the seeds will be uneven. When there is a fine unevenness, there will be a phenomenon of uneven length. If it is directly sown, there will be many seedlings in the process of emergence, and the seedlings should be removed.

Either way, you'll have to make sure that the lettuce grows well. Don't waste seeds and labor, which will also make lettuce more and more expensive. <>

If you grow lettuce in the open field, all the seeds will be washed away after heavy rain. In addition, it is necessary to replant, which is very troublesome in the planting process. You can choose to sprinkle the seeds after the rain has passed, so that the lettuce does not have to be managed.

Lettuce is easy to manage centrally if it is sown, and it is enough to cover it with a film before heavy rain. If the seedling is planted in the event of heavy snowfall, it may be washed away, and there is no way to remedy it at this time. <>

In general, lettuce is very suitable for sowing seedlings first and then transplanting, so that its growth and management are easy to handle. During the planting process, the seeds must be sprinkled thinly, because only in this way can the seeds be sown well. In the process of planting, you can also choose to separate some good distances, so that its yield can be improved to a certain extent.

The seeds of lettuce are very small, and the germination time is generally 5-10 days, and the seeds of lettuce are more expensive, and the most commonly used planting method is seedling transplanting, which is convenient for cultivating strong seedlings. In the process of direct sowing planting, the amount of seeds used is large, especially when planting in a large area, it is difficult to ensure the consistency of seedling growth in the field, and it is impossible to cultivate strong seedlings, and it is difficult to control the consistency of lettuce growth in the later stage.

I think it's better to plant by sowing seeds. The model is different, the planting process is different, the planting time is different, the rotation method is different, the benefits are different, and the cost is different.

I think it's best to choose seedlings because if you sow them directly, it takes a long time to germinate and sprout, and if you raise seedlings, you can reduce the growth time.

The lettuce itself is very good to grow, so the sowing of lettuce will grow more tenacious, and the temperature should be kept at about 20 degrees when planting lettuce.

Sowing seeds is good, which can save manpower and material resources, and the survival rate of lettuce is very high, basically no seedlings are needed.

Seedlings are planted well, which can improve the emergence rate, reduce seed waste, and reduce costs.

Lettuce, also known as goose cabbage, lettuce, is the common name of lettuce, belonging to the family Asteraceae lettuce annual or biennial herbaceous plants. Lettuce originated from the Mediterranean coast of Europe, it has a long history of planting in China, the southeast coast, especially the cultivation area of the two regions has expanded rapidly in recent years, so lettuce planting is better to sow seeds or seedlings?

The growth habit of lettuce. Lettuce prefers a warm environment and is neither cold nor heat tolerant. The suitable growth temperature is 15 to 20 degrees Celsius, the seeds are resistant to low temperatures, and germination can be achieved at 4 degrees Celsius, and the growth period is 90 to 100 days.

Lettuce has a well-developed root system, strong drought tolerance, and is planted in fertile soil with deep soil layer with high yield and good quality.

The benefits of sowing seeds directly. The premise of direct sowing is that the seeds are treated in advance, and the seeds must be disinfected, and then the land is leveled, and some land needs to be fertilized and watered. Then sow the seeds evenly, covering three to four centimeters of thin soil.

The advantage of sowing seeds is that the amount of seeds is sufficient, the seedlings emerge neatly, and the weeds can be controlled.

Benefits of Nursery Breeding: Early seedling raising can shorten the growth period of crops, save seed costs, high germination rate, neat and uniform germination, is conducive to cultivating healthy and strong seedlings, and can also save land and seedling management costs. If transplanting and seedling determination are carried out in advance, the time to market of crops can be advanced and the market can be seized.

Lettuce planting is best to choose seedlings. When raising seedlings, you can choose high-yielding varieties with good cold resistance, disease resistance and strong adaptability, soak the seeds in warm water of about 20 degrees for three or four hours, scrub and dry, and put them in a wet cloth bag to promote germination at a temperature of about 20. Maintain a suitable growth temperature, and the seedlings can be planted in three to five days, and can be planted when four to five true leaves have grown.

Lettuce has always been a common green vegetable on people's tables, with its unique taste and rich nutritional value by the people's love, lettuce planting has been very popular, the following to share with you lettuce planting methods.

First, the selection of lettuce varieties.

In order to guarantee the yield of lettuce, first of all, it is necessary to pay attention to the selection. When choosing varieties, you can consider the habits of different varieties, the climate of the growing area, and their own planting needs. Different varieties of lettuce differ in weight, shape, and taste.

When selecting lettuce varieties, it is also necessary to consider the disease resistance of lettuce seeds, choose varieties with strong resistance to diseases and pests, and reduce the workload of later planting management. Once seeds are found, they should be treated accordingly to remove moldy, rotten or mutilated seeds to ensure seed quality and survival.

Second, the planting season.

In order to ensure a good growing environment for lettuce, the sowing time should be reasonably chosen, as this will directly affect the subsequent growing season. Planting seeds in soil with the right temperature and season is conducive to better germination and survival of seeds.

3. Seedling cultivation.

First of all, to cultivate strong seedlings, it is necessary to have a good seedbed and control the temperature of the seedbed. If the temperature is not suitable, appropriate maintenance measures need to be taken to ensure the temperature of the hotbed. At the same time, if you want to improve the seedling rate and seedling emergence speed, you can also apply a certain amount of farm fertilizer, and plough after fertilization to ensure that the fertility in the soil is uniform.

In order to ensure the germination of seeds, sufficient water should be poured into the soil in advance to ensure that there is enough water to enter the bottom after sowing and the soil moisture is up to standard. Different varieties of lettuce have different requirements for planting density. Therefore, it is important to know the appropriate planting density for lettuce varieties.

In order to improve the adaptability of lettuce seedlings, the temperature can be appropriately lowered at the seedling stage, and more ventilation work can be done to exercise the growth ability of seedlings.

Fourth, rational planting.

After seedlings are raised, in order to improve their yield, attention should be paid to selecting weak seedlings of poor quality to ensure the quality of seedlings. After planting, it is necessary to pay attention to watering the seedlings to ensure the water required for growth. After transplanting, ventilation should be delayed to slow down the seedling stage, so as not to be unstable at the seedling stage and affect the survival rate.

When the temperature is above 20, it should be ventilated in time to prevent overheating in the shed. If the outside temperature is stable at a temperature suitable for the growth of seedlings, the greenhouse film can be removed for management. In order to promote the growth of seedlings and ensure the growth and health of seedlings, watering can be carried out one week after transplanting.

At the same time, the seedlings can be fattened by adding a certain dose of urea to ensure that the water and fertilizer required for their growth can be satisfied. In order to promote the growth of lettuce roots and rosette bushes, the amount of water can be appropriately controlled and urea can be added.

Sowing seeds can be done in spring, summer and autumn, first the land needs to be renovated, then lettuce seeds are put in, and the soil is covered. Then water regularly to make sure the soil is moist, and if it's hot weather, you need to water more. Then you have to fertilize, such as potash and so on.

First of all, the land is leveled, then the seeds of lettuce are sprinkled on the ground, and finally the soil is covered and watered.

First of all, the land is leveled, then evenly sprinkled with lettuce seeds, finally covered with half a centimeter of fine soil, and finally watered.

<>1. Middle and lower reaches of the Yangtze River: spring sowing time is from late January to mid-to-late February, sowing in March and harvesting in May; Autumn sowing is generally concentrated in August to September, and harvest is from November to December.

2. Pizhou Bird South China: Lettuce usually has two sowing periods, one is summer, the other is from September to February of the following year, and the harvest time is from November to April of the following year.

3. Northwest and Northeast Alpine Regions: Sowing in spring and harvesting in summer. However, in recent years, lettuce cultivation techniques have improved, such as growing lettuce in greenhouses.

Generally speaking, choose the right variety and do a good job of maintenance measures, the general situation can be sown all year round, can be the best market throughout the year. This is a vegetable with high economic value in the early days.

Lettuce is grown as follows:1Loosen the soil and sprinkle with lettuce seeds, if you have a lot of land, you can sprinkle the lettuce seeds sparsely and blindly, so that the lettuce has enough room to grow, so that you don't need to wait until the vegetables are ripe before transplanting.

If there is not enough land, the seeds must be sown more intensively. After sowing, water is thoroughly watered and then covered with fine sand. 2.

Lettuce needs a lot of water, so keep the soil moist. When sowing, it is necessary to add more water, generally one week after sowing, so as to better survive the seedling period. After that, it depends on the dryness of the soil, how much more water is on the line, and try to water as little as possible at the time of harvest, otherwise it will affect future storage and transportation.

3.Lettuce has a well-developed root system, leaves have strong drought tolerance, is planted in fertile and moist land, has a high yield and quality, and is suitable for cultivation in all parts of China.
