I like to eat lettuce, how to grow lettuce at home?

Lettuce is a popular green vegetable, rich in vitamin E and carotene, and can also enhance the digestion and absorption of rich fats and proteins. So, how to grow lettuce well? Let's talk about the cultivation method of lettuce.

1. Soil preparation.

Slightly acidic soil with fertile, rich organic matter, strong water and fertility retention, good air permeability, and convenient drainage and irrigation should be selected for planting.

2. Sowing and planting.

When we grow lettuce, we need water to soak the planting. The soaking time should not be too long, about four hours. We need to put the soaked seeds in a humid environment, so that the lettuce seeds are in full contact with the air, which can effectively speed up the germination rate.

At this time, it is necessary to control the soil layer of the nursery. The soil layer should be basically controlled at about seven centimeters. Add some fine sand to the soil.

The addition of fine sand can increase the breathability of the land. When finished, the surface can be covered with some soil that is no more than a centimeter. After waiting for the seeds to emerge, the lettuce can be planted after it has grown to three or four true leaves.

When transplanting seedlings, ensure that the young roots of lettuce can have soil. It is necessary to sprinkle some fertilizer at the planting site. Secondly, the surrounding soil can be used to cover the roots.

3. Fertilizer and water management.

After planting and watering for a week, water the seedlings 1 or 2 times more according to the soil moisture. Lettuce is both drought and moisture, so moisture management is key. Watering 3 5 times during the whole growth period, and the water should be properly controlled in the later stage of heading.

After planting, 10 20 kg of urea was applied on a surface of 667 square meters of water. In the middle and late stages of growth, it is necessary to fertilize outside the roots 3 4 times in time, and supplement calcium, boron, magnesium, copper and other trace elements, which is very important to improve the yield.

4. Pest control.

The main diseases of lettuce are downy mildew, soft rot and sclerotinia sclerotinia disease. These three diseases are prone to occur in high soil moisture, high temperature, or rainy weather;

Precautions: 1) 2 3-year rotation is best with gramineous or sweet potato rotation.

2) Timely clearing of the park; Diseased leaves and plants are removed to reduce morbidity.

3) Strengthening the management of fertilizer cultivation can improve the disease resistance of plants.

Be sure to choose good lettuce seeds, and be sure to plant them in fertile soil, and finally properly watered and fertilized.

You need to choose a place with better light for planting, according to the local soil conditions, choose the right seeds for planting, pay attention to growth, be sure to prepare in advance, you can lay a layer of film, so that you can germinate better, grow faster, pay attention to watering, pay attention to fertilization, pay attention to spraying pesticides.

The first thing is to cultivate the seeds, and then put the seeds in some fine sandy soil, of course, the seed cover area should not be too high, and then the leaves that grow should be fixed, and then the lettuce will grow better and better, and also teach some fertilizer and water.

1. Flower pots, generally speaking, the roots of lettuce are shallow, as long as the flower pots with good drainage can be used. It is necessary to choose a wide and shallow one, and the bottom of the basin has a drainage hole first. Basically, a 15 cm deep pot will do. The material is not limited, it can be used.

2. The selection of cultivation soil, can not choose hard soil, to leave space for the lettuce growth process, it is best to choose decomposed manure plus garden soil and peat, general fertile soil can also be. Make sure that there are enough nutrients in the soil and that there are good drainage conditions.

3. Planting, lettuce is to grow vegetables, as long as seedlings are raised. Spread the seeds evenly under the soil in the pot 3 cm and keep the soil slightly moist. Then put the pot in a ventilated and cool place, and it will germinate in about 2 weeks.

4. Light, plants are generally sun-loving, except lettuce. Be sure to keep it in a cool place, and it is a ventilated place, and it must not be exposed to the sun, just give a little sunlight in the morning or evening. It can also be placed in a place with a bit of light.

5. Sprinkling, in the summer when the weather is hot, you need to sprinkle water every day, always ensure the wetness of the pot soil, and do not let the pot soil be completely dry. Therefore, when the surface of the soil appears slightly whitish, it is necessary to water, and at the same time, it is necessary to prevent water accumulation in the potting soil, which will form root rot.

6. Thin fertilizer is applied frequently, lettuce grows particularly fast, in the daily care must ensure that the fertilizer is sufficient, it is best to apply fertilizer once in 2-3 weeks, with a small amount but the principle of uniformity is generally used to accelerate the growth of liquid fertilizer, can not apply thick fertilizer.

7. Picking, home planting does not need to pick the whole lettuce, you can wait for the leaves on the outer layer of the lettuce to be almost edible, pick it off, the rest of the part is retained, and the lettuce can continue to grow. In this way, you don't need to plant many seeds, you can plant them as needed.
