Edible Mushroom Cultivation Techniques and Precautions for Soilless Cultivation of Flowers

For the soilless cultivation of flowers, the main focus should be on the following two points:

1. Substrate preparation. The main function of the soilless cultivation substrate is to fix the flower plants within the container. Currently, the commonly used soilless cultivation substrates in China are: (1) Sand particles with a diameter of less than 3 mm. (2) Natural gravel, pumice, volcanic rock, etc. with a diameter greater than 3 mm. (3) Vermiculite, a mica-type mineral with good buffering capacity that does not sink in water. (4) Perlite. Mixing it with mudstone and sand gives better results. (5) Peat with good air permeability and strong water-holding capacity. It can be used alone as a substrate or mixed with furnace slag, etc. In addition, furnace slag, brick pieces, charcoal, asbestos, sawdust, fern roots, tree bark, etc. can all be used as substrates. The substrate should be washed and disinfected before use.

2. Nutrient solution preparation. The various elements and their amounts used in preparing the nutrient solution for soilless flower cultivation should be determined according to the flower variety being cultivated, its different growth stages, and different regions. Here is one example formula: add 0.22 g of ammonium phosphate, 1.05 g of potassium nitrate, 0.16 g each of ammonium sulfate and ammonium nitrate, and 0.01 g of ferrous sulfate to 1 liter of water, and mix well to obtain the nutrient solution. The containers used for preparing and storing the nutrient solution should be ceramic, enamel, plastic, or glass vessels; never use metal containers. Usage: for potted flowers, apply the nutrient solution once a week during the growing season, and the amount can be flexibly adjusted according to the size of the plant.
