Simple soilless cultivation of gerbera

First, test varieties sangria (red), rosabella (pink). Second, the cultivation tank and the matrix are made of ordinary red brick bricks with a width of 1m, a length of 5m and a depth of 0.25m, and drainage pipes at the bottom. Pool with mixed matrix, peat: ceramic = 1:1 (volume ratio). Each cubic meter of the substrate was added with 0.4 kg of ammonium potassium nitrate, 1.5 kg of superphosphate, and 0.7 kg of potassium nitrate. Third, the density of planting 9 plants / square meter 3-4 leaf seedlings. The planted area and the soilless cultivation area were planted at the same time, using gravity drip irrigation. Hanging yellow plate with Lilium sinensis to control whitefly. Fourth, soilless cultivation of flowers and quality is better. Regardless of the total flower production or the number of flowers produced per plant, the average length of the flowering branches and the diameter of the flower head, the measurement results in the soilless cultivation area were significantly better than those in the soil cultivation area. Fifth, the incidence of soilless cultivation of pests and diseases is relatively low. Compared with soilless cultivation, gerbera had significantly reduced pests and diseases compared with soilless cultivation. Soilless cultivation did not cause stalk rot, but soil stalk rot occurred at a later stage at 4.5%. Soilless cultivation of gerbera was less whitefly and coal pollution was significantly lower. In soil cultivation, the occurrence of one hundred spiders was lower than that of soil cultivation.
