Selection of Clivia soilless culture substrate: The family cultivated soilless cultivation substrate of Clivia requires health, beauty, no peculiar smell, easy to crush, no rot, loose air, good water retention, light weight, easy to move. Suitable for the soilless cultivation of Clivia, mainly perlite, perlite plus peat, perlite plus vermiculite, vermiculite plus peat and other mixed matrix. Perlite is a mineral formed of siliceous volcanic rock, with a closed brittle structure, good air permeability, moderate water content, chemical stability, small particles, light and clean white, beautiful, hygienic, and strong water retention, because it has passed 1000°C. High temperature, no pathogens, no disinfection, continuous use. Clivia soilless cultivation of nutrient solution preparation: Flower soilless cultivation, that is, substrate cultivation and water culture, water conservation. Substrate cultivation and hydroponics, to add nutrient solution to provide nutrients. The sources of nutrient solution are two channels. One is to purchase special commodity fertilizer granules or nutrient formula mother liquor from the market, and dilute them according to the prescribed concentration. The second is to formulate the formula according to the elemental formula. The main components of the nutrient solution include nitrogen, phosphorus and potassium. Calcium, Magnesium, Iron, Manganese, Zinc, Boron, Copper, Molybdenum, Sulfur and other inorganic substances are prepared at a concentration of 2 to 3%. The formula is: a large number of elements: 6 grams of potassium nitrate, 10 grams of calcium nitrate, 6 grams of magnesium sulfate, 4 grams of ammonium phosphate, 2 grams of potassium sulfate, 2 grams of potassium dihydrogen phosphate; trace elements: disodium EDTA 200 Mg, 150 g of ferrous sulfate, 60 mg of boric acid, 40 mg of manganese sulfate, 10 mg of zinc sulfate, 2 mg of copper sulfate, and 4 mg of ammonium molybdate. Dissolve a large number of elements and trace elements with a small amount of water, and then add two liquids and add water to 10 kg. The pU value of the nutrient solution is about 6.5. For example, if the pU value is high, sulfuric acid should be added. If the pU value is too low, sodium hydroxide should be added for correction. The nutrient solution should not be formulated with sewage. It should be non-toxic, odorless, clean and sanitary. It can be used for long-term preservation.
