Purple cabbage harvest season

Generally, it is sown in January, planted in mid-to-late March, and harvested in June to early July. It can also be sown in late June to early July, planted in late July to early August, and harvested in late October to early November. Usually, with normal management, the yield of purple cabbage per mu is between 2,500 and 4,000 kilograms. Calculated at a price per kilogram, the yield of purple cabbage per mu can reach 2,800 yuan, which is better than other crops.

Purple cabbage planting steps and methods

1. Land preparation, fertilization and ridge making

The growth cycle of purple cabbage is about 80 days. In order to ensure sufficient nutrition throughout the growth period, sufficient fertilizer should be applied before sowing. Generally speaking, fermented organic fertilizer is suitable. After fertilization, deep plowing and ridge formation are carried out, with a ridge height of about 20 cm and a ridge width of about 30 cm.

2. Seeding and germination

The cultivation method of purple cabbage is somewhat similar to that of Chinese cabbage. The sowing steps are to first draw a 1 cm deep furrow on the ridge where the plants are raised, then water the furrow. After soaking, you can sow the seeds. During this period, locusts like to eat seedlings. The seeds should be appropriately dense. After sowing the seeds, cover the seeds with a thickness of about 1 cm of fine soil. After the seedlings emerge, they should be thinned out slowly to ensure the seedling rate. The seedlings will emerge 5 days after the sowing period.

3. Seedling management

In the seedling stage, purple cabbage should pay attention to timely thinning and weeding. When the seedlings are crowded, they should be watered in time and the weather should be dry. The final width of the thinning should preferably be 25~30 cm.

4. Management during the heading period

When purple cabbage grows to 10 leaves, it enters the head-forming stage. During this period, fertilizer and water management must be strengthened. A certain amount of nitrogen fertilizer should be added when watering, but do not apply too much at one time to avoid burning.

5. Harvest

Purple cabbage can be harvested when the stems begin to become firm and change shape. Don't harvest too early. Otherwise, the taste will not be good when it is not fully developed.
