Lettuce is a popular vegetable, so how is it grown?

Step 1: Choose the lettuce seeds you want, choose flower leaf lettuce, glass lettuce or ball lettuce, as the taste of lettuce will vary slightly depending on the seed.

Step 2: Prepare the seedbed, a good seedbed can raise good seedlings, prepare the nutrient soil, if there is no nutrient soil, the soil in the ordinary vegetable garden can also be, the nutrient-rich soil can make the lettuce grow better, and the soil can wait for sowing after it is ready;

Step 3: Soak the seeds to accelerate germination, put the lettuce seeds in wet gauze, soak them for 3-4 hours and then dry them, and then bag them to germinate. When most of the seeds have germinated, you are ready to sow the seeds;

Step 4: Sow seeds, first loosen the seedbed, if the land is relatively wide, you can increase the planting gap between the seeds, leave enough space for lettuce to grow, mix the seeds in the soil, loosen, make the soil level and water, and then spread a layer of soil and then fertilize;

Step 5: planting, seedling age 1 month, can be transplanted and planted, transplantation is best to choose after the rainy day or cloudy day, so that the transplanted lettuce is easy to survive without sunlight, if it is transplanted on a sunny day, the next day to use plastic skin and other things to shade, shade for about three days, and so on lettuce to survive without shading, otherwise the lettuce is easy to die in the sun;

Step 6: field management, watering every day, watering once a day, in short, according to the degree of dryness of the lettuce to judge whether to water, sowing about two weeks or so, the later topdressing should use nitrogen, phosphorus and other compound fertilizers, no need to top dressing in the early stage, but the lettuce planted by themselves is not recommended to apply chemical fertilizer, lettuce planted with green manure is green and healthy. At the same time, to prevent pests and diseases, the main pests and diseases of lettuce are powdery mildew, downy mildew, etc., and the insect pests are mainly whiteflies.

Step 7: Harvesting, which can be harvested in more than two months at most, and harvested, do not cut or pull out the whole tree, but break off the leaves. Lettuce has to be grown very simple, have you learned? Try growing some lettuce!

Lettuce likes a cool climate, so the sowing time is generally carried out in spring and autumn, spring is generally carried out in February-April, and it can be harvested in May-June, and autumn sowing can choose to start sowing at the end of August, and it can be harvested in September-October. However, because different varieties of lettuce have different characteristics, when choosing the sowing time, it is necessary to first understand the description of lettuce seeds, and then combine the local climate for sowing.

The planting method of lettuce is very simple, after planting the lettuce, then spread a layer of plastic film, usually water more, keep the soil moist, or put it in a sunny place, so that it will grow faster.

Be sure to choose better seeds, when planting, you must choose to plant in the greenhouse, the planting temperature should be grasped at about 28 degrees to 30 degrees, and it is necessary to water and fertilize in time, supplement fertilizer, and prune branches and leaves in time to ensure ventilation.

Lettuce is divided into two kinds according to the color of the leaves: green lettuce and purple lettuce. According to the growth state of the leaves, there are two kinds of loose leaf lettuce and ball lettuce. The former leaves are scattered, and the latter leaves are combined.

It is grown through seeds, and this vegetable has seeds, so when planting, you just need to sow the seeds in the ground.

Cabbage is our common vegetable, do you know how it's grown? In general, there are many methods of drilling. However, there are differences between these two methods of large-scale cultivation.

Chinese cabbage is the most common vegetable in our lives, especially in the northern regions. Each Gosta family grows some vegetables that can be eaten fresh or made into pickled vegetables or pickled vegetables. Chinese cabbage has excellent flavor and rich nutrition, and is generally cultivated by sowing and transplanting, which not only has a high survival rate, slow sowing, but also a fast and high yield.

For soil preparation and fertilization, the soil for planting must first be chosen. It is recommended to use mainly loose, fertile sandy soils* or soils rich in organic matter*. Plants grown in the former crop should not have cruciferous vegetables.

Chinese cabbage is usually planted directly one week before sowing, watered after covering the soil, thinning when the leaves grow, and top dressing and irrigation are also carried out during the growth period.

Chinese cabbage should be planted on higher seed plots and close to water sources for easy irrigation and drainage. The mass must be integrated into small pellets, after which the flat plant is first surrounded and sown with water. Direct EM radio is primarily an experimental type of broadcasting, supplemented by on-demand broadcasting.

In the case that the previous crop is not currently empty, mudas can also be used for transplanting. Either way, kale is planted between July and August each year. The temperature in midsummer is suitable for growing Chinese cabbage.

Long-term sunlight allows Chinese cabbage to fully absorb light, accumulate nutrients, and grow healthy and delicious kale, and many people like to grow vegetables at home. In fact, Chinese cabbage is a kind of vegetable native to China, also known as "Chinese cabbage head", "Chinese cabbage head wrapping", "yellow bud white", "no matter what method is used, the amount of seeds directly sown is about 200 grams per mu. Education is not difficult.

1. Growth characteristics.

Lettuce does not like high temperatures, but it is also not cold tolerant, and the optimum growing temperature is 15 to 20 degrees, and the pH value of the soil is the most suitable.

2. Sowing time.

Lettuce is sown for a long time, from August to February of the following year, and the most suitable time is from mid-October to mid-December, and of course from early March to early July, but the yield may not be high.

3. Seed germination.

Lettuce planted in the high temperature season must also be planted for seeds at low temperature germination, first of all, you can soak it in well water for about six hours, scrub it clean, and then wrap it in wet gauze, put it in an environment of 15 to 18 degrees Celsius to germinate, or hang it in the well to promote germination.

4. Seedling transplanting.

Before sowing lettuce, the seedbed should be watered sufficiently, and then the seeds and the same amount of wet fine sand should be mixed evenly before spreading. In winter and spring, greenhouse planting or open field cultivation should pay attention to maintaining the temperature of the seedbed.

5. Scientific fertilization.

Lettuce planting soil requirements, rich in organic matter, and strong fertilizer and water retention ability of clayey loam, basically every 1,000 kilograms of lettuce, it needs to absorb nitrogen fertilizer kilograms, phosphate fertilizer, potassium fertilizer 9 kilograms.

6. Careful planting.

When planting, you must be careful, first of all, you should water the seedbed the day before, and bring a little more soil when the seedlings are raised the next day. When planting, first make a trench on the furrow surface, and the depth of the trench is 4 to 6 cm.

Variety selection of lettuce.

1. Lettuce balls.

The main characteristics of lettuce are that the apical leaves form leaf balls, the leaves are full-margined, serrated or deeply lobed, the leaf surface is smooth or shriveled, and the terminal leaves form leaf balls, round or rounded, and the main varieties are Dahu 659, avant-garde 75, Salinas, Beishan No. 3, Mamic, Turquoise, etc.

2. Wrinkled leaf lettuce.

The main characteristics of wrinkled leaf lettuce are non-balling, basal leaves, leaves long oval, long petioles, wavy leaf margins with notches or deep fissures, leaf surface wrinkles, clusters of leaf clusters like large flowers, the main varieties are "red sail" purple leaf lettuce, safflower leaf lettuce, green wave, Dongshan lettuce, etc.

3. Orthoplastus.

The main characteristics of erect lettuce are long and narrow leaves, growing upright, the leaves are full or serrate, the leaves are thick, the flesh is coarse, the flavor is poor, the varieties are few, the distribution area is not wide, and it is rarely planted in China.

Why do you want to grow lettuce and it's not valuable, why don't you plant orchids in Yunnan, why not plant orchids, such as large-flowered orchids, which are unique in your place.

1. Sowing seeds and raising seedlings.

In order to make the sowing even, a small amount of fine sandy soil can be mixed into the seeds during sowing, and the seeds can be mixed with a new high-fat film (can be mixed with seed coating) before sowing to repel underground pests and diseases, isolate virus infection, strengthen respiration intensity, and improve seed germination rate. After sowing, cover with damp soil and cover with plastic film to moisturize. When the seedlings begin to be unearthed, the furrow mulch should be uncovered in time to prevent growth.

Pay attention to ventilation and ventilation, and shade in case of strong light exposure. The seedling stage is generally not short of water and watering.

2. Scientific fertilization.

Lettuce requires clayey loam soil rich in organic matter and strong water and fertility, lettuce likes to be slightly acidic, and lettuce needs more potassium. During the growing season, nitrogen, phosphorus, and potassium fertilizers are required to be used together. The plot of planting lettuce should be cultivated carefully, and sufficient base fertilizer should be applied before planting, and deep turning should be turned after application, and the bottom water should be watered, and the furrow should be made after drying.

3. Careful management.

Lettuce likes moisture, and sufficient water is required throughout the growth period**. After planting, water the seedlings slowly. After watering the seedlings, the plots that are not covered with plastic film are cultivated and loosened for weeding.

Combined with watering, nitrogen and phosphorus fertilizers are applied in stages. And timely spraying of vegetable stems to make the plant stems thick and vigorous. At the same time, it can improve the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual toxicity.

At the same time, it is necessary to strengthen the comprehensive control of pests and diseases, and at the same time cooperate with the spraying of new high-lipid film to improve the utilization rate of active ingredients of pesticides and consolidate the control effect.

Cultivating strong seedlings:

Seedbed preparation: the seedbed soil strives to be finely broken and flat, apply bottom fertilizer per square meter, sprinkle evenly, plough, level the furrow surface, water the bottom water before sowing, and after the water infiltrates, sprinkle a thin layer of sieved fine soil on the furrow surface, and then sprinkle the seeds.

Seed treatment: Wet the seeds with water and put them in a petri dish or gauze bag lined with filter paper, place them in the refrigerator of 4-6 for 1 day and night, and spray 800 times of the new high-fat film before sowing for seed dressing (it can repel underground pests and diseases, isolate virus infection, do not affect the germination and swelling function, strengthen the respiration intensity, and improve the germination rate of seeds).

Seedling management: reasonable control of temperature at the seedling stage, seedlings are divided when 2-3 true leaves, when the seedlings have 5-6 true leaves, they can be planted, and the seedling root system should be protected as much as possible when planting.

Field management: watering: After slowing down the seedlings, it is necessary to look at the soil moisture and growth to grasp the number of watering. When the temperature is low in spring, the amount of water should be small, and the date of the watering interval should be long; The water demand is high during the peak growth period, so it is necessary to keep the soil moist; After the leaf ball is formed, it is necessary to control the watering to prevent uneven moisture from causing cracking balls and rotten hearts; Spray the new high-lipid membrane to regulate the amount of water absorbed.

Cultivating weeding and fertilization: After planting and slowing down the seedlings, weeding should be carried out to enhance soil permeability and promote root development. In the early stage of growth, top dressing can be done, and at the beginning of balling, fertilizer should be applied reasonably according to the needs of plants.

How to obtain high-yield and high-quality lettuce, spraying strong stems in the vigorous growth period can make the plant stem thick, leaf hypertrophy, leaf color fresh, lush plants, and strong natural taste. At the same time, it can improve the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual toxicity.

Pest control: the main diseases are downy mildew, soft rot, virus disease, dry rot, top burn, etc.; The main insect pests are leaf miners, whiteflies, aphids, thrips, etc. Leaf lettuce is mostly used for raw eating, and pests and diseases should be mainly prevented.

Spraying targeted drugs and new high-lipid films to reduce pesticide residues and prevent and control the infection of germs.

1. Prepare a piece of land, if there is no land, you can also use a foam box, vegetable planting pot or other vegetable planting containers to put some soil in it! The soil is humus as much as possible, and the nutrient-rich soil vegetables grow relatively fat. There is no fertile soil, ordinary soil can also be buried under the soil to bury the remaining vegetables and fruit peels in the kitchen, after decay, the soil will be more fertile, used to grow vegetables, nutrition is sufficient!

2. Loosen the soil with a small shovel and sprinkle lettuce seeds evenly, if there is more land, you can sow lettuce seeds more sparsely, leaving enough space for lettuce to grow, so you don't need to wait for vegetables to grow up before transplanting. If you don't have enough land, you can't just sow the lettuce seeds densely. After the lettuce seeds are sown, they are watered thoroughly and a layer of fine soil is attached.

3. Generally, it is best to plant lettuce in autumn, start sowing in September, water every two or three days after sowing, keep the soil moist, sow about two weeks or so, lettuce will sprout and be unearthed. Due to the different climates in various places, the time for lettuce to germinate and unearth is also different, and the germination and unearthing time is slightly shorter in areas with high temperature, and vice versa in areas with low temperature. See if the lettuce I grow is very tender?

4. After the lettuce is unearthed, watering once every few days, the climate is different, in short, according to the dryness of the lettuce to judge whether to water, it is best to keep the soil of the lettuce slightly moist, so that there is enough water, and the lettuce grows faster. Because I don't have a lot of land, lettuce is sown more densely, too dense will affect the growth of lettuce, so you can eat it with seedlings, and you can also transplant lettuce.

5. Pull out some lettuce seedlings from the dense lettuce and transplant them, it is best to choose after rainy days or cloudy days when transplanting, so that the transplanted lettuce is easy to survive without sunlight, and you can check the weather forecast in advance. If there is no rainy weather, transplant in the evening of 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, otherwise the lettuce that is not shady is easy to die of sunshine under the sun.

6. Because the melon peel leaves of the kitchen were buried under the soil before, these kitchen wastes are very good green manure after decaying in the soil, so the green manure can basically meet the nutritional needs of green vegetables, so the whole lettuce growing season does not need to be fertilized, just watering to meet the growth of lettuce. If your lettuce leaves are yellow, it means that you are malnourished, you can apply some nitrogen fertilizer, you can buy a little compound fertilizer to water it and water it. There is also a way to eat lettuce, that is, do not cut or pull out the whole lettuce by the roots, but break the leaves and eat it, so that the lettuce can continue to grow, and you can continue to eat lettuce until the lettuce blooms and bears seeds!
