Lettuce is very commonly grown in our rural areas. Because of its long leaves, it is called "phoenix tail" in our local area. Lettuce is a leafy vegetable with low calories and high nutrition. It can be served cold or stir-fried. It has a fresh and tender texture and a fragrant taste. Especially when paired with dace and black bean sauce, the taste is unique and will leave people with endless aftertaste. Lettuce is actually a type of lettuce. It is similar to lettuce, but more nutritious than lettuce. It contains a lot of protein, vitamins (A, B1, B2), carotene, a lot of calcium, iron and other nutrients. It also contains nutrients needed by the body. of trace element selenium. It has the functions of clearing away dryness, moistening the lungs and lowering cholesterol.
How do we grow such nutritious vegetables? How can we achieve good taste and high yield? Let’s learn together with any questions! 1. Growth characteristics of lettuce: lettuce is a relatively easy vegetable to grow and can be grown all year round. It is heat-tolerant, cold-resistant, moisture-loving, and grows vigorously at around 20-25°C. It has strong adaptability, few pests and diseases, and does not have high soil requirements, so it can be planted in most soils. 2. Sowing time
Roleola can be planted all year round, and its growth cycle is short. It can usually be harvested in about 45 days after planting. Spring: Generally, the cold weather in January should be avoided. Sowing can be done from late January to late March. Generally, mid-tent planting is used. At this time, germination must be carried out. If germination is not carried out, the germination time may be as long as about 15 days. Summer: that is, from April to June, open-air sowing can be used at this time without germination treatment, but attention should be paid to replenishing water to prevent seedlings from burning due to high temperature and water shortage. Autumn: Generally from July to September, small sheds are generally used. At this time, the temperature is higher and the temperature difference between day and night is large. It is best to soak the seeds for germination before sowing to increase the germination rate. Winter: October to December. Sowing at this time is easy to do in early November, so as to raise seedlings in advance to improve the quality of lettuce. 3. Seed selection treatment
1. Seed selection
Seeds are the foundation of the foundation. There are few varieties of lettuce. When selecting seeds, we mainly choose those with full grains and no pests and diseases. Seeds, and it is best to choose annual self-saved seeds or buy them from regular high-quality seed stores.
2. Germination
Germination can increase the germination rate of lettuce and shorten the germination time. It is usually carried out one week before sowing. Soak the seeds in water at 30°C for about 5 hours, then take them out and drain the excess water on the surface. Wrap them in moist gauze and place them in a cool place for germination. For germination, keep the gauze moist and the temperature is best controlled. Between 15 and 20°C, the temperature should not be higher than 25°C, nor lower than 8°C, so as not to affect budding. 4. Seedbed management
1. Plowing: Although lettuce has strong adaptability, high-quality soil is more conducive to growth. Before sowing, the seedbed must be deeply plowed. Generally, the plowing depth is about 45CM.
2. Leveling: After plowing, the soil should be sorted again to make the soil as finely broken as possible. At the same time, the garden should be cleaned in conjunction with land preparation to clean up grass roots, plant residues, etc.
3. Pre-sowing management: The last task before sowing is to fertilize the plot and make a border with a width of about 1.5 meters. Use about 1,000 kilograms of decomposed farmyard manure per acre (requirements Finely crushed), 300 kg of plant ash, randomly covered with soil and leveled. Make sure the ditches between the borders are clear to facilitate later irrigation and drainage. The last step is watering. This watering must be thorough before sowing to ensure good soil moisture after planting. In order to achieve the purpose of strong seedlings, you can add human manure water at this time, just an appropriate amount.
