1. Planting time: March-April in spring or August-September in autumn.

2. Variety selection: The varieties suitable for potted plants are California 157, Apollo, Green Weiqi, etc.

3. Selection of basin soil: prepare a deep basin, and choose sandy soil as the soil.

4. Sowing: Put the seeds in water at 3°C, then mix them with sand or vermiculite, and then use a wet towel to accelerate germination.

5. Planting: furrow strips are cut for sowing, and then covered with soil and placed on the balcony.

6. management: do a good job in water, fertilizer, conservation and harvesting.

First, variety selection

Varieties suitable for pot planting have shorter plants, more tender stems, more regular size and strong disease resistance, such as California 157, Apollo and Green Weiqi.

Second, the choice of pot soil

1. Potted asparagus needs to be prepared in a deep pot (at least 25cm), and the general shallow pot is not suitable for planting.

2. It doesn't require much soil, but it is recommended to use sandy soil, mixed with river sand or humus soil.

3. Sowing

1. First, plant asparagus seeds at 3? C is soaked in water for 4 days, and water is needed twice a day during soaking.

2. When the seeds are full of water, you can mix in sand or vermiculite, and use a wet towel to accelerate germination. When the seeds are exposed, they can be transplanted into pots.

Fourth, planting

1. Before sowing, the pot surface must be watered with water from the soles of the feet, and furrows should be cut at a distance of 1cm for sowing, and the soil should be covered 2-3cm deep and put in the balcony.

2. The daytime temperature must be controlled at 25-28? C, the night is controlled at 15-18? C. Replenish the seedlings in time after the seedlings are all in place.

3. After seedling emergence, it is dry and wet, and .1% potassium dihydrogen phosphate and .5% urea solution are sprayed. When the seedlings grow more than three aboveground stems, they can be planted.

V. Water and fertilizer management

1. Asparagus has a large amount of roots and relatively developed root groups. During the growth period, it is drought-resistant, waterlogging-resistant, acid-resistant and alkali-resistant. Fertile neutral sandy loam can be used as the pot soil, and 3 kg of decomposed manure and 5 g of compound fertilizer can be applied to each pot, and 1 kg can be added if there is plant ash.

2. The bulb disc of bamboo shoots must be 1-12cm lower than the surface of the planting hole, so that the fleshy roots stretch to both sides, and the soil is covered and watered.

VI. Daily maintenance

1. Place asparagus potted plants in a ventilated place for maintenance, and keep the soil slightly wet every day.

2. Be careful not to let water accumulate in the basin soil, so as not to cause root rot.

3. When the branches and leaves of asparagus grow to 7cm, the asparagus can be topped, so that it will grow strong and the height of asparagus can be well controlled.

VII. Harvesting in time

1. Harvesting of potted asparagus usually begins around mid-May, and can be carried out between 9-11 am.

2. Use a stainless steel knife to cut off the tender stems neatly. Don't leave stubble on the stems. Be careful not to harvest all of them. Each plant can leave 1-2 strong stems for photosynthesis.

VIII. Planting time

The best planting time of asparagus is from March to April in spring or from August to April in autumn. In September, because the temperature can be stabilized at 15? C above, and the light and humidity are suitable, which can improve the germination rate of plants.
