The used organic fertilizer should be thoroughly cooked and broken and sifted. The volume ratio of soil and organic fertilizer is 6:4 to 7:3, which is determined according to the fertility of organic fertilizer. Where peat is available, peat and high-quality manure can be used as organic fertilizer. The proportion of soil, peat, and high quality manure is 5:4:1. When the seedlings are cultivated by using the seedlings, the amount of nutritious soil is less, and the fertilizer is required to retain fertilizer and water, and vermiculite can be used instead of garden soil. The proportion of vermiculite and organic fertilizer is 50% each. For each cubic meter of nutrient soil, 1.5 kg of 15-15-15 compound fertilizer or 500 g of ammonium phosphate and 500 g of ammonium sulfate were added. In order to prevent soil-borne diseases, 70% thiophanate-methyl or 50% carbendazim 100g is added per cubic meter of nutrient soil. In some places, 20% decomposed horse manure, 20% kiln dust, 10% decomposed manure, and 50% onion-garlic soil are used. The other kind can also be used 50% decomposed horse dung, 10% stove ash, 20% decomposed large surface, 20% onion garlic soil. If there is peat soil it is best to use it instead of onion and garlic. In the above mixed nutrient soil, 4 kg of superphosphate, 1 kg of plant ash, and 1 kg of ammonium nitrate were added per cubic meter. Experts suggest that the preparation of cucumber seedling beds varies from place to place, but all require that the nursery nutritive soils have loose texture, good fertility, and no pests and diseases. There are many farmland topsoil that haven't been used to produce melons and cotton in recent years.
