Flower culture and hydroponics are both forms of soilless culture, that is, liquid conservation, but they are obviously different. Flowers used for water culture generally have large bulbs and are rich in nutrients. The growth and flowering mainly rely on their own storage of nutrients, cultivation can be simply immersed in water in the root can be fixed, without feeding. The flowers suitable for raising water mainly include daffodils, hyacinths, and tulips. The key to making water-rich flowers grow and flourish is to select a fully-developed bulb to obtain more nutrients; secondly, change the water frequently and insist on changing it one or two days to maintain sufficient oxygen in the water. Improve root activity; third is to ensure adequate sunlight. In hydroponic culture, roots of plants are fixed on the cover or floating plate of a flower pot, and the root system is soaked in water. The water should be equipped with inorganic nutrients, so it is also called nutrient solution culture. Hydroponic flowers are characterized by their strong resistance to waterlogging. The main varieties are Chlorophytum cyanata, Clivia cactus, Crab caviar, Evergreen, Brazilian wood, spring clumps, and Monstera. The key to hydroponic flowers is to prepare nutrient solutions. According to 10 times the number of macronutrients required for plants, and 1,000 times the microelements, the mother liquor is prepared. Its mother liquor formula: a large number of elements, 6 grams of potassium nitrate, 10 grams of calcium nitrate, 4 grams of magnesium sulfate, 4 grams of ammonium phosphate, 2 grams of ammonium sulfate, Potassium dihydrogen phosphate 0.2g, after the dissolution of water is quantified as 1 liter, reserve use. Trace elements, disodium ethylenediaminetetraacetate 20 mg, ferrous sulfate 15 mg, boric acid 6 mg, manganese sulfate 4 mg, zinc sulfate 1 mg, copper sulfate 0.2 mg, ammonium molybdate 0.4 mg, and the amount of dissolved mixed water is 1 l, bottling for use. The nutrient solution can not be stored with metal or grease, acid and alkali containers. When used in accordance with a large number of elements of mother liquor 100 ml, 1 ml of trace element mother liquor, the mixture of the two added water quantification of 1 liter, with the use. Hydroponic flowers are generally added or replaced with nutrient solution once a week, while paying attention to the pH value of 5.5 to 6.5. The nutrient solution that is swapped out can be used to fertilize earth-planted flowers or other crops.
