1. Test materials and methods
1.1, test Material and seedling method
The method comprises the steps of taking a 'Zhongjiao No. 105' as a test object, selecting full, uniform-sized and glossy sweet pepper seeds (the actual seed quantity is about 3 times of the seedling quantity), and soaking in warm water at 55 ℃ for 25min for sterilization. And (5) after soaking, the seeds are fished out and cleaned, and soaked in clear water for 8 hours. Spreading 4 layers of gauze on the grids, uniformly spreading the soaked seeds on the gauze, covering 2 layers of gauze on the gauze, and thoroughly watering the gauze with pure water. 50ml of clean water is added into the tray to ensure a moist environment. The trays were placed in a constant temperature incubator at 28℃and sprouted in the dark. The germination was observed daily and water was properly supplied.
The seedling substrate proportion is V (turf) :V (vermiculite) :V (perlite) =3:1:1。
The nutrient solution adopts a Hoagland nutrient solution formula, the pH value of the nutrient solution is adjusted to 5.5-6.5, and the EC value is adjusted to 1.5-1.8 mS/cm.
The specification of the plug is 72 holes, the appearance size of the holes is 540mm multiplied by 280mm multiplied by 40mm, and the density is 476 plants/m 2 The plant spacing is 4.5cm, and the plants are cleaned and dried for standby.
After the seeds are 'white', selecting uniform healthy seeds to be sowed into the plug by forceps after the seeds are germinated for about 4 days: (1) the mixed matrix is evenly spread in holes before sowing, redundant matrix on the holes is scraped off by a scraper to make the holes clearly visible, and then the matrix is thoroughly poured by a tidal method (all water is distilled water). (2) The center of each hole is punched with a puncher to obtain a sowing hole, and the depth and the diameter are all preferably about 1 cm. (3) And (5) selecting uniform seeds by using tweezers, and sowing the seeds into the sowing holes with the seeds buds facing downwards. (4) Covering the sown cave tray with vermiculite, scraping redundant vermiculite on the cave lattice with a scraper to make the cave lattice clearly visible. And then thoroughly poured using a "tidal" method. (because the weather is cold, the process is preferably carried out indoors to avoid that the temperature of the matrix is too low to facilitate seedling emergence), and the plug tray is dried for about 10 minutes after watering, so that the water in the matrix is completely discharged. (5) The plug holes are sealed by the preservative film, so that the matrix is prevented from evaporating too fast (the preservative film is removed when the first seedling is observed to be unearthed). And then the sown cave trays are moved to a roof plant factory, and the cave trays are placed in a tray for cultivation.
Plant factoryEnvironmental control: (1) the irradiation treatment for each group was performed from the completion of seeding as shown in table 1. (2) The temperature is set as follows: the temperature was adjusted to about 25℃in the early stage and 22℃in the dark stage. (3) The relative humidity is kept between 50 and 60 percent. (air humidifier set to 45%, appropriate) (4) 2 The concentration was kept consistent outdoors by ventilation equipment at about 400ppm. (specifically, the method can be detected) the water and nutrient solution are irrigated by a tidal method, and the irrigation is carried out once every 2 days, 1.5L of the nutrient solution is irrigated every time (the irrigation can be omitted before emergence of seedlings because of a preservative film). Each time at the end of the dark period and at the beginning of the bright period. (uniformity of irrigation was noted during irrigation) distilled water was irrigated before all cotyledons were unearthed. The first three times (the first 6 days) after the cotyledons are unearthed are irrigated with 1/2 times of nutrient solution, and then 1 time of nutrient solution is irrigated.
