The dry nursery seedbed should be selected from vegetable gardens, high-lying land, fertile soil, well-drained dry land or paddy fields, and the use of low-lying old paddy fields should be eliminated, and soil should be selected for plastic disc throwing, seedling transplanting, and conventional wet nursery ponds. Fertile, well-drained rice fields near Daejeon and water sources, and Dianchi pools are as concentrated as possible to achieve large-scale, seamless breeding. According to the different ways of raising children, we should determine the proportion of farmland in the area and reserve enough seedbed area. The proportion of seedlings transplanted in dry seedlings is generally 1:30-40, and that of medium and large seedlings is generally 1:15-20. The machine plugs in Putian at a ratio of 1:80 to 100. The proportion of plastic discs thrown into the field is generally 1:35-40. Routine moist weaning is suitable for 1:7-8. At present, it is recommended to fertilize the seedling bed special fertilizers such as Zhuangqi nutrient, Dongyulu 3, and other nutrient soils that have not been fertilized in winter or spring or have insufficient fertilization amount, and have been transplanted with rice seedlings and cast in plastic trays. 1-2 days before sowing, apply the seedbed according to the standard usage of the product. The seedlings can be sowed after mixing with shallow mash, which simplifies the fertilization procedure and improves the quality of the seedbed. Conventional wet nursery ponds should be used to turn over the fields early, dry up, open the ditch, apply enough base fertilizer, and apply organic fertilizers. Apply 1250-1500 kg of organic fertilizer per mu of farmland.
