The Latest Cultivation Techniques and Methods Tutorial for Purple Flowering Stalk

Purple flowering stalk, also called red flowering stalk, is a variety of Brassica rapa (Chinese cabbage) in the cruciferous family. It is a perennial vegetable, grown mainly for its flowering stalks, and is primarily cultivated in the Yangtze River basin. As soon as this new type of vegetable hit the market, it was loved by many people, and then, so large-scale promotion and planting began. The details of the process of planting red flowering stalk will be introduced in detail in the article below.

1. Seed selection

There are many varieties to cultivate. Choose varieties that suit the local environment, have strong adaptability, and show excellent genetic traits. For open-field cultivation in early spring, choose mid-to-late maturing varieties, such as Rouge Red red flowering stalk; for planting in early to mid-April to May, choose early maturing varieties, such as No. 2 red flowering stalk; for sowing in early May, choose Erzaozi rapeseed.

2. Land selection

Choose deep, fertile, well-drained sandy loam that is well aerated, retains fertilizer, and holds water well for raising seedlings and planting. First turn the soil; turning to 20 cm is enough, as the roots will not go too deep. Then fine-till the soil so there are no large clods and no compaction. It is best to spray a fungicide such as carbendazim on the seedbed. The seedbed is best about 1.2 m wide and about 5 m long.

3. Sowing

For sowing, you can directly broadcast the seeds evenly on the seedbed, then cover with clean soil cm. Spray water to soak the seedbed thoroughly, then cover with a shade net or dry rice straw to provide shade and keep warm. After that, water once a day; after sprouting, water once every two days to avoid damping-off or seedling blight during the seedling stage. After the seedlings emerge evenly, thin them once, removing weak and diseased seedlings, then harden the seedlings without applying fertilizer or water. After one week of hardening, apply more fertilizer and water, and transplant when two true leaves have grown.

4. Transplanting

Water thoroughly the day before transplanting to make it easier to lift the seedlings without damaging the roots. In addition, apply fertilizer mixed with water once a week earlier to ensure the survival rate after transplanting. Transplant on a cloudy day, or a light rainy day is also fine, to avoid excessive transpiration. Also, the soil in the transplanting field should not be too dry; irrigate appropriately three days before. There will be about a one-week recovery period, during which no watering or fertilizing is needed; wait until growth has recovered for a period before topdressing.

The cultivation of red flowering stalk shares similarities with the cultivation of other vegetables, but there are also differences, and its characteristics must be followed in the cultivation process. For example, red flowering stalk seeds are small and thin-skinned, so they can be sown directly without soaking or pregermination, and they can also sprout quickly in the field.
