A Complete Guide to Growing Seedlings in Nutritional Cups
Abstract Preparing nutritional soil: For nutritional cup seedlings, you can use 2 parts of topsoil from soil free of pathogens and weed seeds, mixed with 1 part of decomposed organic fertilizer to prepare the nutritional soil. After the nutritional soil is disinfected and sterilized, it can be filled into the cups, and then the soaked seeds are sown into the cups. Removing and covering the film: In hot weather, the film needs to be removed for ventilation to prevent seedling burn, and when the temperature is relatively low, the film should be covered in time to prevent cold damage. Generally, the film can be removed at 9 a.m. and covered again at 5 p.m. After the seedlings emerge, thinning should be done in time, and pest and disease control work should be done well.
