2. Waste plastic cups with holes in the bottom are used for seedling raising. Plastic flowerpots or foam plastic boxes (with holes at the bottom) have trays at the bottom. Don't use clay pots. 0.5 kg of clay gravel, 0.5 kg of perlite, vermiculite, peat and rock wool 1-2 kg can be used. Concentrated nutrient solution is divided into 1 and No.2, which must be used by comprehensive dilution. 2 bottles don't need empty plastic bottles (for diluting nutrient solution).
3. invasion. Seeds must be soaked in warm water at 32 degrees Celsius for 6 hours. Soak the substrate. Soak ceramsite and perlite in water for later use. Sow seeds. Plastic cups for seedling raising are filled with soaked substrates, holes are dug with fingers, two seeds are planted in each hole of fruits and vegetables, ditches are used for leafy vegetables, and seeds are planted along small ditches. Cover with substrate, lightly press, cover with plastic bag or film, and wait for emergence.
4. pour the liquid. After emergence, the diluted nutrient solution should be watered 1-2 times a day, and the exudate in the dish is appropriate. Vegetable seedlings. When the seedlings grow two leaves, they begin to be sparse, leaving only one seedling in each hole and pulling out the extra seedlings. Change the basin. When the seedlings grow to have 3-5 real leaves, they need to change the big pots.
5. First lay a layer of soaked ceramsite on the bottom of the basin to facilitate drainage, then lay perlite, transplant the seedlings together with the substrate into the big basin, and finally cover the perlite with a layer of ceramsite. After changing the pot, pour the liquid thoroughly for the first time, and it is advisable to ooze from the tray. Pour the liquid. Watering leafy vegetables once every two days and twice a day, and watering fruits and vegetables only twice a day, without watering.
