planting season and time of purple cabbage
Generally speaking, purple cabbage can be cultivated all year round. Spring cabbage is sown from late October to December, summer cabbage sold from March to May in the following year is sown 3~4, and autumn cabbage cultivated in cold regions is sown 6~7, and winter cabbage sold from September to November is sown from December to February in the following year.
Common varieties of purple cabbage are Hongzi Gan No.1, Zaohong, Jushihong and so on. Most varieties are also planted in spring and autumn.
purple cabbage is usually sown in January, in the middle and late March, and harvested from June to early July. You can also sow from the end of June to the beginning of July, sow from the end of July to the beginning of August, and harvest from the end of October to the beginning of November. Usually, after normal management, the yield of laver per mu is between 25 and 4 kilograms. Calculated by the price per kilogram, the yield per mu of purple cabbage can reach 28 yuan, which is better than other crops.
Steps and methods of planting purple cabbage
1. Soil preparation and fertilization for ridging
The growth cycle of purple cabbage is about 8 days. In order to ensure adequate nutrition during the whole growth period, plantar fertilizer should be applied before sowing. Generally speaking, fermented organic fertilizer is suitable. After fertilization, deep ploughing and ridging are carried out, with the ridge height of about 2 cm and the ridge width of about 3 cm.
2. Seeding and emergence
The cultivation method of purple cabbage is somewhat similar to that of Chinese cabbage. Sowing steps: firstly, draw a ditch with a depth of about 1 cm on the ridge where you get up, then water the ditch. After soaking, you can sow seeds. At this stage, locusts like to eat seedlings, and the seeds are properly dense. After sowing, cover the seeds with fine soil with a thickness of about 1 cm. After the seedlings emerge, they should be thinned slowly to ensure the seedling rate. Seeding time will be 5 days before emergence.
3. Seedling management
At the seedling stage, attention should be paid to timely thinning and weeding of purple cabbage. When the seedlings are crowded, they should be watered in time and the weather is dry. The final width of thinning seedlings is preferably 25~3 cm.
4. management of heading stage
when the purple cabbage grows to 1 leaves, it enters the heading stage, and the management of fertilizer and water must be strengthened at this stage. When watering, add a certain amount of nitrogen fertilizer, but don't apply too much at a time to avoid burning.
5. Harvest
Purple cabbage can be harvested when the stem begins to change firmly. Don't harvest too early. Otherwise, the taste is not good when it is not fully developed.
