How do you grow lettuce? Lettuce planting How to grow lettuce

Lettuce is one of our common vegetables, and I believe everyone will be familiar with it. Although lettuce is bitter when eaten raw, its crispy, tender, and refreshing taste is still loved by many people, and lettuce is also used in many vegetable salads. In addition, in recent years, the cultivation area of lettuce has been expanding, so more and more people are growing it.

If you want to know how to grow lettuce, you need to strengthen your knowledge of the varieties of lettuce, as well as the conditions for lettuce planting, the growing environment and field management. <>

The first thing to say is the growth environment of lettuce, lettuce is more like a cold environment, generally 15-20 is suitable for its growth, and there are certain requirements for air and soil moisture. The choice of varieties is also more important, when choosing lettuce seeds, we should choose healthy and full seeds, eliminate wilted and moth-eaten seeds, and also choose seeds that are resistant to high temperature and cold, strong disease resistance, and the selection of varieties should be considered according to the local climate, and the bad seeds will be eliminated, which is also of great benefit to the growth of lettuce in the later stage. <>

Secondly, it is necessary to soak the seeds and promote germination, this step is quite important, and I believe that people who have experience in this area know this step. For example, planting coriander and spinach all need to be soaked and germinated. Soak the seeds in water for 3-4 hours, put the soaked gauze at 15-20 places to germinate, and sow when most of the seeds are white, if there are no germinated seeds can be eliminated by themselves.

For the management of water and fertilizer, it is necessary to know that the most important thing in the whole growth process of lettuce is not the lack of water, it is necessary to keep the soil moist, and it needs to be watered every 3-4 days to ensure that the soil is moist. After 7-10 days of slow seedling, top dressing once, the first time can be topdressed 10 kg mu, and the rest can be topdressed 15 kg mu. <>

The last thing to say is disease control, lettuce has almost no pests, but the disease is mainly downy mildew, it is necessary to plant seedlings appropriately, increase air permeability and light transmittance, in order to reduce the occurrence of downy mildew, which is also very important, otherwise lettuce is easy to die, even if the previous work is done well, it is useless to do a good job of disease prevention and control in time.

First of all, we should find a place where the land is relatively moist, then sprinkle lettuce seeds, then apply some fertilizer, and then water some water when the lettuce grows seedlings, and then water it every three to five days, so that the lettuce can grow strongly.

The first thing is to choose to plant in March or April, then to prepare the land in time, and then to add some farm fertilizer, and then to soak the seeds for 4 hours before planting, and then to cover the soil in time, and then to choose the right density.

1. Land preparation: Before planting lettuce, the land should be prepared to ensure that the plot is soft and fertile, and the potted plants are prepared with suitable potting soil. 2. Sowing seeds into the soil

After the soil is ready, sprinkle lettuce seeds directly on the surface of the soil, cover the thin soil, and spray with water to moisturize. 3. Later maintenance: lettuce seeds like light, to bask in the sun, find that the soil is dry and water in time, and the environment is suitable for germinating seedlings soon.

4. Seedling transplanting: lettuce seedlings can be transplanted when they grow 3 true leaves.

There are three ways to grow lettuce at home:

1. In fact, lettuce can be planted all year round, as long as the temperature is below 20 degrees, it can be sown at any time, and if the temperature is high, you want to plant lettuce, you can also choose some heat-resistant lettuce varieties to plant, the general lettuce is very suitable for sowing in autumn, so that it will continue to grow in winter.

There are many types of lettuce, some are smaller, some can form balls, some have larger leaves, some have a better taste, and some purple-leaved lettuce, and the planting methods are similar.

2. As for the choice of lettuce planting tools, as long as it is a container that can be loaded into the soil, it can be planted, pay attention to flower pots or other containers, foam boxes, empty oil drums, and there must be drainage holes, otherwise the growth is not good, and it is easy to yellow leaves, because the potting soil is easy to accumulate water.

It is recommended to use some plastic long pots, so that you can plant a lot of seedlings, and it is easy to place, plant a few pots on the balcony, more neat, clean and beautiful. You can use ordinary garden soil for potting soil, and if you don't want to buy soil back, you can also mix soil yourself.

It is to add some fertile humus to the soil, or add some well-rotted organic fertilizer, chicken manure, sheep manure, etc., to increase the fertility of the soil, and continue to provide nutrients for lettuce seedlings.

3. Before sowing, make the potting soil looser, softer, pinch the potting soil by hand, it will not form a clump, if the seeds are sprinkled unevenly, you can mix them with the sand, sprinkle them in the pot, sow them for the first time, try to sprinkle a little less seeds, and be even.

Then water thoroughly and put it on the balcony in a well-lit, ventilated place with a temperature of about 20 degrees, and the germination rate will be very fast. After germination, when three leaves generally grow, if the seedlings are too many and too dense, you can pull out some, or wait until the seedlings grow up again, you can transplant some seedlings.

The transplanted lettuce seedlings will grow better, and the transplanted and untransplanted seedlings are completely different, and the transplanted lettuce will grow particularly lush and the leaves will be larger. In short, the spacing between seedlings should not be too small, otherwise they will not get enough nutrients and sunlight, and the growth will be poor.

After germination and seedling, it is necessary to increase the light, after growing up, it is necessary to supplement some fertilizer, which must be fertilized, you can pour some cake fertilizer water, or sheep manure soaked in water, watered in the pot soil, there is really no organic fertilizer, you can give some compound fertilizer or chemical fertilizer, no fertilizer must not grow lush, and at the same time watering should be timely, the potting soil is too dry, and the lettuce leaves are not watery enough.

Only sufficient fertilizer and water and light can make the leaves more delicious and taste better. Lettuce is very easy to grow, you will know if you have planted it once, and the balcony has become a world of lettuce, and it has become a beautiful and vibrant little vegetable garden, and you can eat the freshest lettuce.

1. Lettuce is generally cultivated by planting seedlings. Choose well-growing, shiny lettuce seedlings and put them in well-drained soil, press the soil lightly and water them. Keep the seedlings spacing at about 20 cm.

2. After about two weeks, top dressing is carried out, sprinkled on the roots of lettuce seedlings, and mixed with soil.

3. Lettuce should not receive too much light, and direct sunlight or lights should be kept away as much as possible, otherwise the stems and leaves will grow and the leaves will become hard, which will affect the eating. Lettuce should be done on a sunny day when removing the side sprouts, and if rain falls into the sprouts, the lettuce leaves will turn yellow.

4. When the lettuce plant grows to 25 cm, the lettuce can be harvested. You can break the edible parts and cut the whole lettuce.

5. In order to maintain the taste of lettuce, it is best to eat and pick it now. Usually, it is best to handle lettuce by hand, because the part of lettuce that has been processed with a knife is easy to change color.

1. Soil: To plant lettuce, you need to choose loose, fertile and breathable soil, and the soil needs to be disinfected and deepened before planting, and an appropriate amount of base fertilizer needs to be applied to the soil. 2. Seed selection:

Growing lettuce requires selecting healthy, plump seeds, soaking them in soil water for a while, and then removing them and placing them on a damp cloth to germinate. 3. Planting: Evenly spread the processed lettuce seeds in the soil, and then cover with a thin layer of soil.

The growth habit of lettuce

Lettuce is a one-year high-branched or two-year-old herbaceous crop, the leaves are long obovate, densely packed into cabbage-like leaf balls, can be eaten raw, like a cold and cool environment, neither cold-tolerant, but also heat-resistant, the suitable temperature for growth is 15 20, the appropriate temperature for germination is 18 22, and almost no germination when it is higher than 30.

Lettuce has a well-developed root system, wax on the foliage, and strong drought tolerance, but it is cultivated on fertile and moist soil, with high yield, good quality, and suitable soil pH value, and is widely cultivated in various parts of China.

Lettuce is a light-loving plant, it needs to be maintained in a sunny environment, the light is not enough to grow poorly, when the light is strong in summer, it needs to be shaded appropriately to avoid sunburn.

Lettuce is grown as follows:

1. Sowing: Shoot next to usually raise seedlings first, lettuce seeds are too small and too light, need to be accompanied by fine sand, stir evenly in a container, and then sprinkle on the soil, cover the soil centimeters, a thin layer, 15 20 degrees about 3 5 days germination temperature is higher than 25 degrees when it is difficult to germinate, summer planting needs to be germinated, the seeds are soaked for 1 night, and then wrapped in wet gauze, put in the refrigerator (about 5 degrees), about half of the seeds are exposed and then sown.

2. Seedling stage: change the belt to keep the soil moist, not dry, and keep the soil permeable. 2 3 true leaf time seedlings, 5 8 cm from the kernel reed.

3. Transplanting: When the seedlings grow to 5 or 6 true leaves, they should be watered thoroughly before moving, and the soil on the roots should be moved to a large pot together. Loose leaf lettuce plant spacing 15 cm, fruiting 30 cm. Water thoroughly, put it in a cool place in the summer to slow down the seedlings, and the roots will stand firm in about 1 week, and the sun will shine normally.

4. Fertilization: apply fertilizer once a week after transplantation, and then apply organic fertilizer or compound fertilizer of whole nitrogen, phosphorus and potassium once after transplantation 2 weeks and 4 weeks after transplantation. Stop fertilizing 2 weeks before harvest.

5. Watering: Watering in the morning and evening at high temperatures, it is better to water a small amount frequently, but avoid waterlogging, suitable for water control in the early stage of growth, and keep it moist.

Lettuce is grown as follows:

1.Prepare the planting site: Choose a well-drained, fertile soil environment and make sure the drainage system is good.

3.Watering: Keep the soil moist and water every 2-3 days.

4.Fertilization: Apply well-rotted organic fertilizer at 500-800 pounds per acre with fertilizer.

5.Light: Stay in the sun, every 4-5 hours.

6.Harvesting: When the lettuce grows to 15-20 cm tall, it is ready to be harvested

The lettuce planting steps are as follows:

Material preparation: land, lettuce seeds, shovel, water, etc.

1. Land preparation.

Prepare a piece of land, and if you don't have it, you can also use a foam box, planting pot or other planting container to put some soil in it! The soil is humus as much as possible, and the nutrient-rich soil vegetables grow relatively fat. If there is no fertile soil, the soil in the ordinary vegetable garden can also be used, and the remaining vegetable peels in the kitchen can be buried under the soil, and the soil will be more fertile after decaying, and it will be used to grow vegetables with sufficient nutrition.

2. Sow seeds. If there is more land, you can spread lettuce seeds more thinly, leaving enough space for lettuce to grow, so you don't need to wait for the vegetables to grow before transplanting. If there is not enough land, the seeds can only be sown densely.

After the seeds are planted, they are watered thoroughly and a layer of fine soil is attached.

3. Growth. Generally, lettuce is best planted in autumn, and sowing begins in September, and after sowing, Keichi waters every two or three days to keep the soil moist, and it takes about two weeks to sow the lettuce and sprout out of the earth. Due to the different climates in different places, the time for lettuce to sprout and emerge is also different.

4. Transplantation. Pull some lettuce seedlings out of the dense lettuce and transplant them, preferably after a rainy day or on a cloudy day. If there is no rainy weather, transplant in the evening on a sunny day, keep the transplanted lettuce at a distance of more than 10 cm, water enough, and use plastic skin and other things to shade the next day, shade for about three days, and wait for the lettuce to survive without shading.

So that we can wait for the lettuce to ripen.

Origin of Species:

Lettuce belongs to the genus Lettuce of the Asteraceae family. It is an annual or biennial herbaceous crop. Green leafy lettuce has more cellulose, white leaf lettuce has thin leaves and fine quality, purple leaves and red leaf lettuce have bright color and tender texture.

Lettuce is native to the Mediterranean coast of Europe, and lettuce was not cultivated much in China in the past, and was mostly grown in the south. With the reform and opening up, after frequent foreign exchanges, in the past 10 years, in some large cities and some open coastal cities, the planting area of lettuce has gradually increased, and then many cities in the interior have also introduced trial planting, which is welcomed by consumers. Lettuce has become a fast-growing green leafy green chain spike in China.
