2, rock wool cultivation: rock wool cultivation is planted in pre-made rock wool, rock wool is melted by 60% diabase, 20% limestone and 20% coke at 1600 ° C high temperature 0.005 mm of fiber and pressed into pieces.
3. Substrate cultivation: The substrate cultivation is to fix the root system of the crop in an organic or inorganic matrix, and supply the nutrient solution of the crop by drip irrigation or trickle irrigation.
    Third, the advantages of soilless vegetables
1. It can increase the yield: the various nutrients required for crops in soilless culture are artificially formulated into nutrient solution. The nutrients can be scientifically supplied according to the crop species and the different growth stages of the same crop, so the crop grows robustly and grows. Strong.
2, the environment is clean and hygienic: the application of soil-free cultivation is inorganic fertilizer, and soil cultivation application of organic fertilizer, fertilizer decomposition and fermentation, producing odor and polluting the environment, will cause the eggs of pests to breed, harm crops, soilless cultivation does not have these problems .
3, water-saving, fertilizer and labor: no soil cultivation does not require cultivating, tumbling, weeding and other operations, saving labor and labor.
4, to avoid continuous cropping obstacles: soilless culture can avoid continuous cropping obstacles, reasonable rotation of land in vegetable cultivation, avoiding repeated years of heavy mites is one of the important measures to prevent serious occurrence and spread of disease, and soilless cultivation has fundamentally solved this problem.
5, not subject to soil restrictions: soilless cultivation makes the crop completely out of the soil environment, not restricted by soil quality and water conservancy conditions. Many deserts, wilderness or difficult-to-cultivate areas on the earth can be used without soil culture methods.
6. Make full use of space: Soilless cultivation can get rid of the constraints of the land, so it can be free from space constraints. It can be used to plant flowers on the flat roof of urban buildings, which can expand the cultivation area invisibly, and can also be produced according to people's will.
Soilless culture is a water-saving and fertilizer-saving planting mode. Its cultivation method is simple, the cost is low and it is also high-yield. It is worthy of all the growers to try.
