Maize seedlings are generally transferred from the end of April to the beginning of May, and the best transplanting leaf age is controlled at 2.5Mel 3.0 leaf stage, and water is poured in time after transplanting, mainly to control temperature and humidity. The key point is heat preservation before emergence to the second leaf stage. The temperature in the film is usually controlled at 20 ℃ 25 ℃. If the temperature is more than 30 min, the two ends of the film should be ventilated and cooled, and the humidity in the film should control the soil without whitening. If the topsoil of the seedling bed turns white, the film should be opened and watered. And timely strict cover, often keep the soil moist, timely transplanting, reasonable and close planting, the transplanting seedling age is generally from 2-leaf to 3-leaf stage, no later than 4-leaf stage, the key to transplanting is to protect the root system, improve the survival rate, graded according to seedling size, strength, sectional transplanting, and carry out directional transplanting, north-south ditching, east-west orientation, leaves and vertical direction. The best transplanting depth is at the boundary of green and white on the stem. The main transplanting time of maize seedlings is from the end of April to the beginning of May, and the best transplanting effect is controlled at the seedling stage of 2.5 to 3.0 leaves.

Second, how to raise seedlings of corn?

1. Nursery bed selection

Choose sunny (increase light time), leeward (increase temperature and preserve soil moisture), close to the transplanting plot as seedbed (transplanting convenience).

2. Prepare nutritious soil

Choose soft and fertile soil with good water absorption as nutritious soil, according to the situation, we can add organic fertilizer and compound fertilizer properly, and mix it with water-soluble and nutritious soil.

3. Seed treatment

Before sowing, the selected high-quality corn seeds will be soaked and germinated, and when the seeds are white, they can be sowed (pay attention to disinfecting and watering the seedbed the day before sowing). When sowing, only one seed can be placed in each block area of the seedbed, and the radicle of the seed is down, then covered with soil, then watered to ensure that the soil is wet, and finally covered with arch shed and plastic film on the seedbed.

4. Seedbed management

Nursery bed to maintain enough humidity, timely watering, the temperature is generally controlled between 20-25 ℃. Control the amount of water after emergence to prevent overgrowth. When the corn grows to two leaves, it begins to dry and refine the seedlings, making the seedlings adapt to the external environment. After that, transplanting can be carried out, and the best transplanting time is from two leaves to three leaves, and no more than four leaves at the latest.

From the above, we can know that corn seedlings are generally transplanted at the end of April to early May, so corn seeds are needed to raise seedlings before that. The editor also introduced some seedling raising methods to you in detail, hoping to help you.
