What are the cultivation methods of cruciferous collard greens? What about planting prospects? Can it be eaten raw?

Kale, a biennial herb, is a horticultural variety of kale (cabbage). The structure and shape are very similar to cabbage and have been widely planted in China. Do you know the planting methods of collard greens? What are the planting prospects? Can I eat it raw?

I. what are the planting methods of kale?

1. Sowing time

The sowing time of kale is usually from mid-July to early August. if sowing prematurely, the old leaves will be yellowed in the later stage of growth, which will not only increase the difficulty of management, but also prolong the management period. If the sowing time is too late, it is easy to cause the crown diameter of the leaves to fall short of the required specifications when coming out of the nursery.

2. Seedling raising method

Sowing can be carried out in the open field. Generally used as a hole or border plate seedling raising these two methods. In order to drain water in July and August with heavy rainfall, the seedbed needs to be built with a high bed about 20 centimeters above the ground.

3. Sowing method

Before sowing, we need to set up the arch shed and prepare the plastic film, which can be covered in time once the heavy rain, so as to avoid reducing the emergence rate due to Rain Water scouring. The seedling substrate can be selected with 40% peat soil and 60% perlite, and carbofuran is used to disinfect the soil and reduce the occurrence of diseases and insect pests. Before sowing, it is necessary to spray the soil with water, and then sow the seeds directly on it, the covering depth is just right to cover the seeds, and there is no need to water again after sowing. At a temperature of about 15-20 ℃, seedlings can emerge in about a week.

Breeding precautions:

Transplantation is usually carried out when the seedlings grow 4-5 true leaves, colonization is carried out in mid-late November, and generally requires 3-5 transplants. Kale can be transplanted with bare roots. Peeling off the outer old leaves during planting not only highlights the color of the heart leaves, but also reduces water consumption and promotes the plant to resume growth as soon as possible.

Kale likes fertilizer, and there is a great demand for nitrogen fertilizer in the early growth stage, so it is necessary to topdressing more fertilizer to ensure adequate nutrient supply. When planting, prepare sufficient base fertilizer. Topdressing can be started about a week after seedling transplantation. When the climate turns cool in autumn, the growth rate speeds up and the amount of nutrients absorbed increases. At this time, we should also pay attention to providing sufficient water and fertilizer. Stop applying nitrogen fertilizer when the plant begins to change color. When the amount of fertilizer is insufficient, the outer leaves turn yellow and fall off.
