The cost of soilless cultivation is simply the cost of adding a full set of soilless cultivation facilities on the basis of traditional soil cultivation greenhouses or greenhouses. Before using soilless cultivation, all kinds of equipments need to be installed before they can be put into operation. Therefore, the one-time investment before the production is the main problem considered by the producers. Next, Xiaobian talks about the one-off investment in the main way of soilless cultivation. [ One-time investment in various soilless culture systems ] (1) trough training Grooved materials: made of brick, cement, concrete, bamboo raft or wooden slats, etc., nowadays more red bricks are used, the length depends on the terrain of the greenhouse; A 0.1mm thick plastic film is placed on the bottom of the cultivation tank to effectively prevent soil pests and diseases; The cost of trough culture: 30m3 of trough culture substrate per mu of land. After 3-4 years, the replacement of the substrate cost per mu is 2,500 yuan, and the irrigation equipment (nutrient solution tank, nutrient solution transport pipeline, etc.) needs 2000 yuan. It takes 2,000 yuan for bricks to cover 10,000 pieces of red bricks per acre, and 700 yuan for 60kg of polyethylene film per acre. Therefore, a one-time investment of about 7200 yuan per mu of tank cultivation facilities is required. (two) bag culture The bag is made of a milky white polyethylene film (0.1 mm thick) for growing bags of 70-100 cm and 35 cm wide. At least one dripper is required for each plant, and a one-time investment of 7500 yuan is required. (3) Rock wool cultivation The specification of rock wool block for seedling raising is 7.5cm×7.5cm×5cm; The rock wool planting mat for planting is 100cm×20cm×9cm; The irrigation system uses drip irrigation, and at least one dripper is set per plant, and a one-time investment of about 8,500 yuan per mu. (4) Substrate hydroponics The cultivation trough can be made of soil, cement or iron sheet, with a one-time investment of about 5,000 yuan per mu, a cement planting tank with a one-time investment of about 8,000 yuan per mu, and a tin-making cultivation tank with a one-time investment of about 10,000 yuan per mu. (5) Nutrient liquid membrane cultivation technology The nutrient liquid film cultivation technique is to use a metal or foam plastic plate or a hard plastic to make a cultivation tank having a depth of 10 cm and a width of 10 to 20 cm, and mainly planting leafy crops. The one-time investment per mu is about 35,000 yuan, not less than 15,000 yuan. (6) Deep liquid flow method and dynamic floating root method Both the deep liquid flow method and the dynamic floating root method belong to the deep-water cultivation method, and the one-time investment per mu is not less than 1.5 to 20,000 yuan. (7) Floating plate capillary hydroponics The floating tube capillary hydroponics method is made of polystyrene, and the investment for each acre is 15 to 200,000 yuan. (8) Organic ecological soilless culture As can be seen from Table 4-3, the one-time investment per mu of organic ecological soilless culture system is 6,300 yuan. Table 4-3 One-time investment per mu of organic ecotype soilless culture system (yuan).
