How to plant snow? The name of Xue Lihong may be strange to some friends. In fact, the snow is red in the snow. It is a seasonal vegetable in the southern part of China. It is very common in the north. Let's take a look at the key points of snow cultivation techniques. 1. Land preparation Red planting soil in the snow requires high fertility. Level the land, make it into strips, and make sure the drainage is good. The drain should be wide enough for one foot. The weeds that have been cleaned up should be taken away in time. Second, nursery Snow seedlings require fertile soil properties. Generally, one month before seedling cultivation, compost can be used first. The soil should be fine, and the seeds should not be buried very deep, two to three centimeters. Third, colonization The red planting time in the snow is early, and the time is controlled at 8~10 in the morning. There must be some soil in the planting seed. When the snow seedlings grow to about 12 to 15 cm and then transplant, the transplanted seedling spacing should be controlled at 20~30cm, and the water must be poured after transplanting. Fourth, fertilizer water Fertilizer water is the decisive factor in the growth of snow. Fertilization is generally based on mixed phosphorus and potassium fertilizers and nitrogen fertilizers. Of course, nitrogen fertilizer is the main component. A certain amount of urea can be applied in the early stage, but a small amount of fertilizer is applied in one week after planting. You can apply more in the medium term. Do not fertilize for half a month before picking. V. Pests and diseases The prevention and control of red pests and diseases in snow must be done well, otherwise it is easy to cause production cuts. The hazards of snow red are mainly insects, especially aphids. If you find that the red leaves in the snow are not the right color, remember to check the plants in time. The above is the key point of cultivation in the snow, the Xiaobian family's eating method is snow red fried meat or soup, fried, etc. What do you do?
