Many vegetable bases have one or two greenhouses planting purple cabbage every year. They feel that the market is listed before and after the spring, and the income is still very good. Color vegetables such as purple cabbage are very popular in the market, and purple cabbage is not difficult to plant in general, with less pests and diseases, high yield, and planting benefits are still very good. So how do you plant it? Let's take a look at it. Main points of winter spring 茬 purple cabbage planting management 1, variety selection Winter and spring purple cabbage generally choose resistant early maturing varieties, the ball weight is about 1 kg, such as early red, we grow more, the growth is quite good. In the winter, in order to get to the Spring Festival, it is necessary to strictly arrange the time of cabbage planting. First of all, we must know that in the winter and spring, it takes about 70-90 days for the cabbage to be planted and planted. It takes about 45 days from the planting to the harvest. Our entire planting is arranged in this way. 2. Greenhouse seedlings In mid-October, seedlings were planted in the greenhouse. Now the seedlings are well-fed with nutritious soil. Seedling trays are used to raise seedlings. The cabbage seedlings are not large. It is possible to use a 72-hole seedling tray. One seed is placed in one hole when planting. After sowing, the temperature should reach 25 °C during the day, 15 °C at night, and 2-3 days to emerge. If the temperature is not enough, add some heating facilities, such as geothermal line. 3, watering management About 5-7 days, the cabbage seedlings are all out, and the temperature is lowered by 5 °C to prevent the cabbage sprouts from growing. Before the cabbage seedlings grow to 3 true leaves, if the seedling tray is not particularly dry, do not water, so that it can grow. Strong seedlings. After the management of the cabbage seedlings, the water should be seen dry and wet, not dry or not poured. If the seedlings are weaker, they can spray some foliar fertilizers, stop watering for about seven days before planting, and carry out drought-resistant exercise. 4, fixed points When the cabbage seedling grows to 6-8 pieces of true leaves, it can be planted. It is necessary to carry out cold-resistant exercise 7 days before planting. The daytime temperature is around 15 °C, and the night temperature is about 8 °C. This temperature is the temperature in the greenhouse. close to. At the beginning of the second year of January, it was planted in the greenhouse. Before the planting, the plant will apply 5000kg of organic fertilizer per acre, 30kg of superphosphate, 50kg of compound fertilizer, 40cm*60cm when planting, and 2,500 plants per mu. At this time, the temperature of the greenhouse is basically the lowest in a year. When planting, do not pour large water. This will lower the ground temperature. Just pour water, and pour a water to a seedling (about 1L). About 5- After 7 days of slow seedling, you can pour a little more water. 5, water and fertilizer management 30 days after planting, that is, in the middle of February, the cabbage enters the ball-forming period. During this period, the amount of water and fertilizer needed is large. Always keep the soil moist, and avoid dry and wet. Topdressing 2-3 times during the whole balling period, and urea can be applied. The initial topdressing is 15kg per mu, and the mid-term is 10kg. In the later stage, it can be topdressed or not. When the purple cabbage leaves are tight, they can be harvested. The whole planting process of the greenhouse purple cabbage is like this, perhaps not very careful, but the general planting ideas are like this, and the key parts are also introduced, you can plant and ponder.
