When is lettuce grown? When is lettuce planted, can it be planted at any time?

Lettuce is usually a common vegetable, deeply loved by people, lettuce is usually best planted in autumn, generally lettuce can be planted in spring 3 and 4 months, 5 June can be picked, autumn 8 and 9 months planting, to 10 November when the harvest begins, but the autumn planting is higher than the spring planting, and the nutritional value is particularly rich.

Lettuce is best planted in autumn August to September.

Lettuce can generally be sown in spring and autumn, it has a high nutritional value, deeply loved by people, so when is the most suitable time to plant lettuce, lettuce is best planted in autumn 8 and 9 months, this time period can make lettuce grow better.

Lettuce can be planted in March and April in the spring, and can be picked in May and June, or it can be planted in August and September in the fall, and it can be picked in October and November. <>

Planting method: First of all, you need to prepare some excellent lettuce seeds, but also prepare the soil suitable for lettuce growth for planting, sprinkle the seeds on the soil to keep the soil moist, and cover a layer of plastic film, waiting for the seeds to take root and germinate before normal maintenance.

Management work: When we plant lettuce into the soil, we can water it every 5 days, do not fertilize it when it does not germinate, wait for it to take root and germinate, and apply rotten organic fertilizer every 10 days, so as to promote the lettuce to grow better.

No matter where you are, you can't plant if the temperature is above 27 degrees Celsius during the day, but you can plant if it's below 27 degrees.

Lettuce is one of the vegetables that is often eaten, whether it is grown in a small area in production or at home, potted or soilless. Relatively speaking, it is a good variety, there are few pests and diseases, and there is almost no need for spraying for cultivation management, however, it is not easy to grow lettuce beautifully. The lettuce we grow tends to be small, thin and tall, unlike the lettuce grown by others, which looks as round as a flower.

1. Sow in March in spring, or raise seedlings in the shed from the end of January to the beginning of February, and transplant in March. Lettuce seeds are small, only 25g seeds are needed for one acre of land. The suitable germination temperature of seeds is 15-20, and the emergence of seedlings is slower in early spring under low temperatures.

In order to harvest early, we can raise seedlings in small arch sheds and cultivate them in the open field, or we can sow them when the temperature reaches about 5 and plant them a month later. Sandy loam soil is the best way to raise seedlings, which can improve the emergence rate, and farmhouse fertilizer is the main base fertilizer.

2. In early August, in autumn, shady seedlings or sow seeds directly in the field after germination. The germination temperature of lettuce seeds is higher than 25, and it is difficult for the seeds to absorb water, so the seeds need to be treated at low temperatures. First, the seeds are soaked for 3-4 hours, then placed in an environment of 5-10 to accelerate germination, and 70-80% of the seeds are exposed to white before being sown.

The germination process is usually done in the refrigerator or refrigeration. Sow after watering. After sowing, the ground is covered with straw and other mulch and shade nets.

When 60%-70% of the seedlings are unearthed, remove the straw to keep the soil moist.

3. Shading cultivation and greenhouse warming cultivation can advance and extend the growth period. Lettuce can be cultivated in the shade at high temperatures, ensuring that the temperature is in the range of 15-25, growing well, and the maximum temperature is not higher than 30. In the low temperature season, protected land cultivation can achieve the corresponding temperature and humidity conditions, and can also obtain high yields.

Autumn sowing lettuce is in the high temperature period, and the seedbed is prone to water loss, which has a great impact on the emergence and growth of seeds, and often keeps the soil moist. The shade net is only uncovered in the morning and evening after the seedlings are unearthed, and the shade can maintain normal growth at noon.

If this is not the case, you can choose to plant in spring or autumn, and the temperature must be controlled between 18 degrees and 23 degrees when planting, and then you should choose high-quality seeds, do a good job of seed seedling, and pay attention to the density and depth of planting.

It is not always possible to plant lettuce, but it is generally better to plant it in March in the spring or in early August in the autumn.

No, it is generally chosen to plant in spring or autumn, so that the outside temperature will not be too low, and it will not affect the growth of lettuce.

No, it is best to plant lettuce in the spring, because it has a relatively fast growth cycle and can generally be eaten in the summer.

1. Lettuce is a common vegetable, which is deeply loved by people, and it is best to plant lettuce in autumn.

2. General lettuce can be planted in March and April in the first season of spring, and can be picked in May and June, and planted in September in August and October, but the yield of autumn planting is higher than that of spring planting, and the nutritional value is particularly rich.

1.Selection and sowing of improved varieties: suitable varieties should be selected according to needs, such as glass lettuce, Caesar, ball lettuce, mosaic lettuce, Dahu 659, etc.

2.Prepare the seedbed: lettuce seedlings should choose water-retaining, fertilizer-retaining sail wheels, fertile sandy loam soil.

Bed soil preparation: 10 square meters of seedbed with 10 kg of rotted organic fertilizer, 10 kg of ammonium sulfate, kg of superphosphate, kg of potassium sulfate, mix evenly and spread the rake finely, water the bottom of the water, and sow after water infiltration.

3.Sowing and raising seedlings: In order to make the sowing even, a small amount of fine sand can be mixed into the seeds during sowing, covered with centimeter-thick tidal soil after sowing, and covered with plastic film to moisturize.

The sowing rate per mu is 30-50 grams. When the seedlings begin to be unearthed, the furrow mulch should be uncovered in time to prevent growth. The temperature of the seedbed should be controlled at 18 20 during the day and 12 14 at night.

Pay attention to ventilation and ventilation, and shade in case of strong light exposure. When the seedlings grow to 2 3 true leaves, the seedlings are divided according to the plant row spacing of 6 8 cm, and they can be planted when they grow to 4 or 5 true leaves, and the seedling stage is generally not short of water and watering.

4.Scientific fertilization: lettuce requires clayey loam soil rich in organic matter, strong water retention and fertility, lettuce likes slightly acidity, and soil pH value of 5 7 is appropriate.

For every 1,000 kg of lettuce produced, it needs to absorb kg of nitrogen, phosphorus and potassium, of which bulb lettuce needs more potassium. During the growing season, nitrogen, phosphorus, and potassium fertilizers are required to be used together. The plots of planted lettuce should be deeply cultivated, and sufficient basal fertilizer should be applied before planting, 3000 3500 kg of rotting farmhouse fertilizer per mu should be applied, and deep turning should be turned after application, and the bottom water should be watered, and the furrow should be made after drying.

5.Careful planting: the seedbed is irrigated the day before planting to make the seedlings moist, and the seedlings are raised the next day with as much soil as possible to reduce root damage.

When planting, first ditch on the furrow surface, the ditch depth is 4 6 cm, 70 centimeters disturb the rice furrow surface planting 3 rows, after the ditch is applied to 25 kg per mu after the ternary compound fertilizer is irrigated, after water infiltration, the seedlings are placed according to the plant spacing of 24 cm to seal the ditch, the furrow surface is raked flat, covered with mulch, and the seedlings are introduced out of the film.

6.Post-planting management: lettuce likes moisture, and sufficient water is required throughout the growth period**.

After planting 5 7 days, water 1 time to slow seedlings. After watering the seedlings, the plots that were not covered with plastic film were cultivated twice and loosened for weeding. After watering 3 4 times, combined with watering, nitrogen and phosphorus fertilizer are applied in stages, and 15 20 kg per mu is applied.

Stop watering before harvest to facilitate storage and transportation.

7.Pest control: the main diseases of lettuce are downy mildew, soft rot, virus disease and sclerotinia sclerotinia and so on, among which the harm of sclerotinia and soft rot is greater, crop rotation can be taken, appropriately reduce planting density, watering should not be too much, often shallow hoeing, keep the soil surface dry, find that the diseased plants are pulled out in time, the dead leaves are burned intensively, agricultural streptomycin and dysenium can be sprayed after the onset of the disease, and chlorothalonil can be sprayed every 5 7 days in the high temperature and high humidity season for the purpose of prevention.

The main insect pests are aphids, thrips, ground tigers, etc., which are controlled by oxidizing dimethoate and killing Ding.

8.Scientific harvesting: non-bulbling lettuce can be harvested in a timely manner according to the market, and the bulbous lettuce is harvested after the leaf bulb is tight, which will affect the yield too early, and the stem in the leaf bulb will be elongated too late, and the quality of the leaf bulb will become loose and decrease.

Lettuce is best sown in July and August. Lettuce has a relatively short growth cycle and can be planted all year round as soon as it touches the skin.

How to grow a bad vegetable for a laugher:Sowing is generally carried out in spring and autumn, spring is generally sown in February and April, harvested in May and June, and autumn sowing can be started at the end of August and harvested in September and October.

Lettuce is a warm, moist vegetable that should be kept well hydrated during its growing season. Every 5 to 7 days, you can water the seedlings. After watering the seedlings, loosen the soil twice to maintain the air permeability of the soil, and clean up the excess impurities and weeds.
