How to grow the latest purple cabbage

Chinese cabbage is a common vegetable in our life, but compared to purple cabbage, purple cabbage has a very high name. It first became popular in South Korea, and it was only planted in China in the past two years. It is actually a hybrid of Chinese cabbage and cabbage. Because it is relatively fresh, many people have begun to plant it, so how should purple cabbage be planted? Come and have a look with the editor.

1. Sowing and raising seedlings

The planting method of purple cabbage is the same as that of general Chinese cabbage, which is generally planted by direct seeding and seedling transplanting, but its seeds are much more expensive than Chinese cabbage seeds, so in order to control the cost and improve the seedling emergence rate, generally choose the method of seedling transplanting. It is necessary to maintain sufficient light when raising seedlings, and when the seedlings grow 3-4 true leaves, 0.3% urea solution can be sprayed and irrigated, which is beneficial to the growth rate of seedlings and the cultivation of strong seedlings.

2. Transplanting

The day before transplanting, it is necessary to pour enough water on the seedlings to make the soil moist. The purpose of this is to hurt the roots when transplanting seedlings, usually transplanting at noon the next day. In addition to be careful of root damage when transplanting, each seedling should also carry a clot of 6-8 cm in diameter to avoid rhizome damage. After transplanting, watering again the next day is beneficial to slow down the seedlings so that the seedlings can grow rapidly, and then be irrigated every 5-7 days, but it is important to stop watering two weeks before transplanting.

3. Field management

After transplanting, when the soil surface is slightly dry, it is necessary to cultivate and turn the soil in time to avoid soil hardening and some root system development; when weeds appear in the plot, it is necessary to combine watering and fertilization to carry out soil cultivation and weeding work, and the whole growth period should be carried out 4-5 times. Generally speaking, it is necessary to apply fertilizer twice during the growth and development period of purple cabbage, the first time in 10-15 days of transplanting, 15-20 kg of potassium sulfate compound fertilizer per mu with irrigation, and 25-30 kg of potassium sulfate compound fertilizer per mu in the rosette stage.

4. Pest control

Purple cabbage should prevent virus disease and downy mildew in the process of planting, and the common pests are aphids, cabbage insects and Plutella xylostella. Farmers must pay attention to them when planting, and drug control should be carried out in time once found.
