Ice cabbage planting time

Ice cabbage is planted when the temperature is 20-30 degrees Celsius, and is usually planted in August-September in autumn.

Planting time of southern iceberg: iceberg is not suitable for the growing environment in the south and is not suitable for planting.

Northern iceberg planting time: Iceberg is sown in the north and cultivated in autumn.

Origin of ice vegetables

Ice vegetables are mainly distributed in Heilongjiang, Jilin, Liaoning, Hebei, Shanxi, Shaanxi, Gansu, Qinghai, Xinjiang and Inner Mongolia and other regions in my country. They are also distributed abroad in Europe, Siberia and Central Asia of Russia, and Mongolia.

How to grow iceberg plants

1. Choose soil

Iceberg seeds are small and need to be loose, breathable and well-drained soil. You can also directly Plant the seedlings in nutritious soil and transplant them after germination.

2. Seed soaking and sowing on demand

Soak the iceberg seeds in warm water for 3 hours, then plant, cover with a layer of 3-5 mm fine soil on top, and maintain the ambient temperature At around 20 degrees, when the seedlings grow 5 leaves generally after 30 days, they can be transplanted.

3. Transplanting seedlings

When transplanting seedlings, protect the root system. It is best not to transplant in rainy days or hot weather. Water once, but not too much. There should be no accumulation of water.

4. Field management

The suitable temperature for the growth of iceberg is between 20-30 degrees. It is drought tolerant and does not require too much water. It keeps the soil dry and prevents its diseases. Mainly caused by damping-off disease in the seedling stage, the main pests are grubs, snails, etc. Timely spraying is required to prevent and control pests and diseases.

Ice cabbage field management technology

1. Soil management

Ice cabbage has strong absorption of heavy metals. In order to avoid soil contamination, it needs regular disinfection and It is necessary to replace the soil, renovate the soil in time, and improve the permeability of the soil.

2. Water and fertilizer management

Iceberg seedlings can reduce watering and are relatively drought-tolerant. They do not need to be watered within 10 days after planting until the soil dries out or the leaves become wilted. Watering can be done only when the situation occurs. Watering should be done thoroughly at once, but no water accumulation should occur. Sufficient base fertilizer should be applied before planting, and top dressing should be done during the growth period.

3. Light control

Icy vegetables like a sunny environment and need more sun during the growth period, which can improve its quality. In addition to light, the temperature must also be controlled. , preferably between 5 degrees and 30 degrees. The temperature is high in summer, so be prepared for ventilation.

4. Disease and pest control

Icy vegetables have strong disease resistance, so the occurrence of diseases is relatively rare. They are mainly threatened by pests, such as aphids, chafers, etc. Prevent in advance, build insect-proof nets, insect traps, etc. around the area for prevention and control, and reduce the application of pesticides.
