1. Preparation before sowing Generally speaking, Chinese flowering cabbage has the best production effect in hot and rainy summer. However, it is often accompanied by heavy rain at this production stage, so it is more difficult to topdressing. Therefore, before planting, we should apply sufficient base fertilizer, so that when it is inconvenient to topdressing in rainy season, the soil can still supply nutrients. Generally, we use decomposed pig manure and its special fertilizer for leafy vegetables per mu, and then mix them according to a certain proportion, and then fully mix them with soil.

Second, after the seedlings are planted in the short flat shed, the seedlings should be shaded and cooled in time to prevent the seedlings from dying from the sun. The concrete way is to support a fixed shape with that short thick bamboo pole frame, and then build another frame every three to five meters, with the height of the shade shed about 8cm, and then cover it with gauze. If there is a storm, then we need to reduce the height by about 2cm to enhance the wind resistance. However, it should be noted that generally we only need to cover it for about 2 days. Ten days before harvesting, we need to remove the shade shed to improve the quality of Chinese cabbage. Planting methods and management points of Chinese flowering cabbage < P > III. Fertilizer and water management

1. Fertilized Chinese flowering cabbage has shallow roots and poor absorption capacity. Chinese flowering cabbage grows rapidly in summer and autumn, so it needs a lot of nutrients. Generally, we plant Chinese flowering cabbage, and the planting density may be relatively high, so we should increase the amount of fertilization to meet its nutritional needs. Thin fertilizer should be applied frequently when topdressing Chinese cabbage to minimize the loss of fertilizer. When the seedlings of Chinese flowering cabbage spread their first leaves, we irrigate them with low-concentration human urine manure, and then chase the decomposed manure every five days, and the concentration can be gradually increased. After that, topdressing for three or four times. If the temperature is the highest in summer, we choose to fertilize in the evening when the temperature is slightly lower, and never fertilize in the hot afternoon. 2. Watering can not only replenish soil moisture, but also reduce the surface temperature of Chinese cabbage and soil temperature. In summer, cabbage is usually watered two or three times a day, once in the morning and once in the evening. If the temperature is too high, water should be drenched again at noon, but the amount of water drenched should not be too much, as long as the water is drenched on the surface of leaves and soil.

Appropriate harvesting of early-maturing Chinese flowering cabbage varieties, from sowing to harvesting, usually takes 3 to 4 days. Don't pick it too early, otherwise the cabbage will be bitter at this time, and don't pick it too late, otherwise the leaves will be thicker and the taste will be poor.
