Planting method and time of ice vegetables

Planting method: ice cabbage should choose soft soil, breathable and moisturizing soil, soak seeds with warm water, 2-3 seeds in each hole, then cover soil and water for about 20-40 days, planting holes according to plant spacing 20cm or so, row spacing 30cm or so. In the hot weather, it can be properly shaded and sheltered from the sun, cool down, water again when the soil is white, and can be harvested about 60 days after sowing. Planting time: spring or early autumn, when the temperature is 20 ℃, planting is better.

First, select soil for planting

The main results are as follows: 1. Ice cabbage is a kind of salty plant with high salt tolerance and dry tolerance, its seeds are relatively small, and the ability of arching soil is relatively poor, so the soil with good air permeability, moisture retention and soft soil should be selected before planting.

2. The seedling can be raised indoors, the seedling tray can be prepared, and then the nutrient soil dominated by coconut brick can be put into the substrate to raise seedlings.

Second, planting time

The suitable planting time for ice cabbage is spring or early autumn, and it is more favorable for its germination to keep the temperature around 20 ℃ after sowing.

3. Sowing and raising seedlings

1. Soak the seeds in warm water of about 30 ℃ for about 2-4 hours before sowing, and then sow about 2-3 seeds in each hole. If you sow seeds on a seedling tray, you can sow about 2-3 seeds according to 9cm.

2, after sowing can be covered with a layer of fine soil, about 3-5 mm, should not be covered too deep, otherwise it will affect the germination rate of cabbage, after sowing the temperature should not be too high or too low, should be controlled at about 20 ℃, if the temperature drops, should be appropriate heat preservation, high temperature should strengthen air circulation, so that the temperature can be reduced.

3. Under normal circumstances, about 20-40 days after sowing or when the seedlings grow 4-5 leaves, they can be transplanted and planted.

Ice vegetables are best sown in the season with the most suitable temperature in spring or early autumn. The goal of temperature management after sowing is about 20 degrees.

IV. Transplanting and planting

1. Generally, transplanting ice cabbage should not choose the period of overcast and rainy days or high temperature, and in addition, the roots of seedlings must not be damaged during seedling initiation, otherwise it will affect the survival rate of seedlings.

2. First of all, dig planting holes, each hole plant spacing is about 20cm, row spacing is about 30cm, after planting, cover soil, and then watering, should not be excessive, the temperature can be controlled at about 25 ℃.

V. late-stage management

The main results are as follows: 1. Ice cabbage is sensitive to high temperature in summer, and it is suitable to grow at the temperature of about 20-30 ℃, so it is necessary to shade and avoid the sun in summer. In order to reduce the temperature of the planting area, ventilation should be strengthened.

2, ice vegetables are more resistant to drying, high temperature weather should be watered appropriately, not too much, generally when the soil surface is white before watering.

VI. Harvest

Ice vegetables grow rapidly in the middle and later stage, and a large area will grow in a period of time, which can be harvested about 60 days after sowing. Pre-cooling treatment should be done after harvest, which is more conducive to long-distance transportation.

7. Nutritional value of ice cabbage

Ice cabbage is a kind of vegetable with high nutritional value, which is rich in amino acids, anti-acidification substances, sodium, potassium, carotene and so on. The sour taste of ice cabbage is a natural sour taste, which embodies one of the characteristics of cabbage, cabbage, lettuce and so on.
