What are the planting methods of lettuce, lettuce planting methods

Lettuce cultivation methods

Planting time. Lettuce likes a cold climate, so the sowing time is generally carried out in spring and autumn, spring is generally sown in 2-4 months, 5-6 months can be harvested, and autumn sowing can be sown at the end of August, 9-10 months can be harvested, because different varieties of lettuce characteristics are different, so when choosing the sowing time, you can first understand the description of the lettuce seeds bought, and then combine the above sowing time for sowing.

Prepare the seedbed. It is best to choose sandy soil, loosen the seedbed and apply farmhouse fertilizer to ensure that the soil of the seedbed is finely crushed and flat, and rich in nutrients.

Soak seeds to promote germination. First of all, the healthy lettuce seeds are soaked in clean water, the soaking time is generally about 3-4 hours, the water temperature can be kept at room temperature, after soaking, gently scrub and dry the water, and then sow when the seeds germinate.

Sowing seeds and raising seedlings. Before sowing, the seedbed should be watered once and some dimethoate solution can also be sprayed, which can effectively prevent the occurrence of insect pests. When sowing, you can use 1 gram of seeds per square meter, and then cover with a layer of fine soil after sowing to create a good growth environment for lettuce.

When the seedlings are unearthed, remove the mulch in time, and at the same time strictly control the temperature, the suitable growth temperature is generally 15 20. In addition, water is also indispensable, generally watering once a week, after the temperature drops, reduce the number of watering.

Soil preparation and tillage: Before planting lettuce, the soil is deeply cultivated to a depth of 20 cm and organic fertilizer is applied. Sowing seeds and raising seedlings.

After soaking, the seeds are mixed with fine sandy soil and sown for sowing. Seedling transplanting: After the true leaves grow, the seedlings are divided according to the plant spacing of 8 cm.

Field management: watering the seedlings once 7 days after planting, cultivating and weeding and loosening the soil twice.

1. Land preparation and ploughing

Lettuce is suitable for planting in the deep soil layer, fertile, convenient drainage and irrigation of sandy loam soil, deep ploughing depth of about 20 cm, break the soil clods, apply organic fertilizer after exposure to the sun and ripening, mix evenly and rake finely leveling, water enough water, so that the soil remains moist.

2. Sow seeds and raise seedlings

Lettuce seeds are soaked before sowing to promote seedlings, drained and mixed with fine sandy soil, sown by sprinkling, cover a layer of 3-5 cm of moist soil on the surface, cover the soil surface with transparent mulch, play the role of heat preservation and moisturizing, and wait until about 3-5 days to grow seedlings.

3. Transplanting seedlings

When lettuce seedlings grow 3 true leaves, divide the seedlings according to the plant spacing of about 8 cm, grow 5 true leaves when the seedlings are transplanted, and water enough water the day before the seedlings to keep the soil moist, and the soil is attached to the seedlings to protect the root system, and the depth of transplanting is about 4-6 cm.

4. Field management

Lettuce planting about 7 days after watering a slow seedling water, watering combined with weeding and loosening soil 2 times, weeding to reduce nutrient loss, loosen the soil to increase the air permeability of the soil, conducive to crop root growth, watering the use of diluted nitrogen and phosphorus fertilizer to provide nutrients, 7-10 days before harvest stop watering.

Planting lettuce requires the use of soil with rich trace element content and loose soil, and before planting, lettuce seeds need to be seedled, and lettuce can be transplanted to suitable soil after waiting for the seeds to grow into seedlings smoothly, and at the same time water the appropriate amount of water in the soil to make lettuce grow better.

1. Planting soil

Growing lettuce requires choosing the right soil. Lettuce is suitable for growing in soil with rich organic matter content and good drainage, so it is best to use sandy loam or humus soil with rich nutrient content and good air permeability when planting lettuce, and after planting, it is necessary to loosen the soil regularly for lettuce.

2. Seedling treatment

Plants need to be seeded before lettuce is planted. First of all, you need to select the seeds that are full of grains and have not suffered from pests and diseases, and then you can sow the seeds directly in the soil, bury them with the right amount of fine soil, and water the soil with the right amount of water, and wait for the seeds to germinate and grow into seedlings before transplanting.

3. Carry out transplanting

When transplanting, the lettuce seedlings need to be dug out directly from the soil, and then the roots that grow too fine are cut off with scissors, and the lettuce seedlings can be planted in the soil prepared in advance, and after planting, the lettuce needs to be replenished with water in time to keep the soil moist, so that the lettuce can better adapt to the transplanting environment.

4. Later maintenance

In the later maintenance of lettuce, it is necessary to provide reasonable nutrients for the plants, improve the growth rate of lettuce, and also need to provide suitable light for lettuce, so that lettuce can carry out photosynthesis normally, and it is also necessary to bury insecticidal pills in the soil where lettuce is planted to eliminate pests in the soil and prevent and control insect pests in lettuce.

Soak the seeds in clean water, remove them to dry, and put them in a bag for germination. Sowing seedlings: Water the soil once before sowing and then sprinkle lettuce seeds into it.

Field management: Water every 5-7 days during the growing period.

1. Planting time

Lettuce prefers cooler climates and is usually sown in spring and autumn, with spring being done in February-April and harvesting in May-June, and autumn at the end of August and September-October, but the exact timing depends on the local climate.

2. Treat the seeds

Lettuce before sowing, the seeds should be treated, which can not only shorten the germination time, but also improve the germination rate, first soak the seeds in clean water for 3-4 hours, dry the water and put it in a bag to promote germination, and wait until most of the seeds germinate when you can sow it.

3. Sowing seedlings

Before sowing, water the soil once, then sprinkle the lettuce seeds into the soil, and cover with a layer of fine soil to create a good environment for its growth, wait until 1 month after the seedlings are unearthed, transplant and plant, pay attention to stabilize the seedlings during the planting period, and water in the ditch at the same time to provide nutrients.

4. Field management

Lettuce in the growth period, generally every 5-7 days watering 1 water, if in case of rainy weather, in time to discharge the excess water in the field, the soil is in a moist state for a long time, is not conducive to the growth of plants, with spraying dimethoate solution to prevent the invasion of insect pests.

Soil preparation: Dig deep into the soil and apply well-rotted farm manure. Sowing seeds and raising seedlings.

Due to the small size of lettuce seeds, most of them are sown by scattering. Field management: Thinning seedlings after emergence, and watering the seedlings once five to seven days after planting.

Disease control: reduce the probability of disease by adopting crop rotation and reducing planting density.

1. Land preparation treatment

Before planting, lettuce should be treated with soil, first turn the ground once, and then apply well-rotted farmhouse fertilizer to ensure sufficient nutrients, and water thoroughly.

2. Sow seeds and raise seedlings

Choose lettuce varieties with strong disease resistance for planting, because the seeds are small, most of them are sown by sowing, directly sprinkle the seeds evenly on the soil, and cover a thin layer of soil, and then water thoroughly to keep the soil moist, and germinate in a week.

3. Field management

When the lettuce germinates, it is necessary to do a good job of watering to ensure that the soil is in a moist state, start to intersect the seedlings after emergence, and water the seedlings once five to seven days after planting, and then combine the watering to apply nitrogen and phosphorus fertilizers, and stop watering before harvesting, which is conducive to storage and transportation.

4. Disease prevention and control

The main diseases of lettuce are downy mildew, soft rot, virus disease and sclerotinia sclerotinia and so on, among which sclerotinia and soft rot are more harmful, and the probability of disease can be reduced by crop rotation, reducing planting density, scientific watering, etc.

The method and time of cultivation of lettuce are as follows:

1. Planting method:

1. Choose potting soil. Lettuce is suitable for growing in fertile and loose soil, well-drained soil, when planting, choose loose soil, nutrient-rich sandy soil, and well-drained pots, and use sunlight to sterilize the potting soil to avoid bacteria causing damage to lettuce.

2. Sowing and planting. How to grow lettuce. When sowing lettuce, the potting soil should be loosened, and then the seeds with full grains and no mold and deterioration should be sprinkled into it, and watered once, soak the whole soil, and the lettuce seeds will germinate after a week, and after the seedlings have grown three or four leaves, the thinly growing lettuce should be removed.

3. Post-management. How to grow lettuce. In the later management, organic fertilizer should be buried in the soil to provide nutrients for lettuce, and water should be replenished in time after fertilization, and fertilizer should be diluted to avoid fertilizer damage to lettuce.

Lettuce loves light and should be placed on a balcony or by a window to allow the plants to receive plenty of light.

Lettuce planting time is divided into spring and autumn, spring is generally between March and April, autumn is generally between July and August, the lettuce seeds mixed with sandy soil are slowly sprinkled on the seedbed soil, covered with a thin layer of soil, planting to maintain row spacing, after planting to fertilize once, watering once permeable.

The sowing time is generally carried out in spring and autumn, and the spring is generally sown in February and April, and can be harvested in May and June; Autumn is generally sown in late August and harvested in September-October.
