Purple Cabbage has good cold resistance, compact ball, bright color, strong adaptability, high yield, good quality, and high planting efficiency. It is suitable for cultivation in open field and protected land. Yield per mu is generally 2500-3000 kg. Its spring dew-ground cultivation techniques are described as follows: First, nurture strong seedlings 1. Variety selection. The early-maturing variety "Ye Hong", which is suitable for cultivation in the spring from the Netherlands, can be selected. Its leaf color is purple, the leaf ball is oval, and the single ball mass is 0.75 to 1 kg. About 65 to 70 days from planting to harvest. 2. Suitable sowing. Spring cultivation can be nursed in protected land from mid-January to mid-February, seeded with dry seeds, and cultivated with seedlings for nutrition. Before the planting, the nutrient soil was fully watered, and the soil after the sowing was 1.5 cm thick. Then cover the film to make the seedlings grow early. 3. Seedling management. The general seedling age is 70 to 90 days, sowing to 2 true leaves occurs 20 to 30 days. The daytime temperature at the seedling stage is maintained at about 25°C, and the temperature at night is 15°C. After the seedlings were released, the temperature was lowered to 20°C during the day and 10°C during the night. Seedlings grow from 3 true leaves to 6-8 true leaves for 45-60 days. Before the planting, exercise at a low temperature, keep it at about 15°C during the day and 7°C～8°C at night, gradually approaching the open temperature. The criteria for strong seedlings are: 6 to 8 true leaves, short internodes, thick leaves, deep color, thick stems, and well-developed root groups. Second, the soil fertigation Purple cabbage, fertilizer, fertilizer in the base general Mushi high-quality ring fertilizer 5000 kilograms, 15 kilograms of ammonium phosphate, potash 15 kilograms, and the soil tills the earth to do the trick. Generally made of 1 to 1.2 meters flat. Third, colonization It is not advisable to plant early in the open field so as to avoid premature planting and convulsions. Generally after the Ching Ming Festival in spring, when the temperature stabilizes above 6°C, it is planted. Take "water stable seedlings", the amount of water is not too large, in order to promote the slow seedlings. The planting density was 50 cm and 50 cm, and 2500-2600 plants were planted per acre. The planting depth was left above the leaves, and the heart was not embedded in soil as the standard. If improved mulching cultivation is adopted, it can promote early maturing and high yield. Fourth, field management Purple cabbage requires a large amount of fertilizer, and a total of 4 to 5 dressings are conducted during the seedling stage, rosette stage, and balsamic stage. The lotus root period and the filling period require the largest amount of fertilizer and should be reused. After easing the seedlings, the seedlings should be poured with 1 time of sapling seedlings. After 10 to 15 days after easing seedlings, 15 to 20 kg of urea should be applied to the water per acre. In the middle of the rosette, a second dressing is performed. Mushi urea is 15-20 kg, DAP 20 kg and Potash 10 kg. From the time of colonization to the late 30 to 40 days of the rosette, the beginning of the inner leaf of the rosette indicates that it has reached the ball stage. This period is the period when the purple cabbage grows fastest and has the largest amount of growth. It is also the period when the maximum amount of fertilizer and water is needed. Therefore, the ball stage should be combined with water dressing 2 to 3 times, each time Mushi DAP 10 to 15 kilograms, a small amount of fertilizer in the later period, in particular, before the harvest do not fertilizer too large to avoid the ball.
