Star flower seedling management method
Star flower seedling management method: Germination: Maintain high humidity at a moderate temperature of 23 ° C, and germinate 6-9 days after sowing. Light: During the germination, the light intensity is 1000 lux, which is conducive to the germination of the seeds. After the seeds are germinated, let them gradually see the light, and finally to the full sun. At the same time, reduce the moisture of the medium to avoid the lengthening. After germination, the light intensity needs 10,000-30000 lux. As the seedlings grow, the leaves need to be enhanced to 54,000 lux and the temperature is controlled. Temperature: After germination, the temperature can be lowered to 20-22 °C until the true leaves begin to grow. After the true leaves begin to grow, the temperature can be lowered to 18-20 °C, and the middle and late stages can be reduced to 15-18 °C until colonization, which will be beneficial to the seedlings. Strong. pH value: The suitable pH value is 6.5-6.8, and the pH value of the medium should not be lower than 6.0. Otherwise, the seedlings are easy to be burnt due to iron poisoning, and the plant grows slowly. Calcium nitrate Ca(NO3)2 can be applied in an appropriate amount to reduce the undesirable phenomenon caused by too low pH. Fertilizer: After the cotyledons of the seedlings are unfolded, the application of "Cymidine" 2000 times solution, once a week, about 5 weeks after sowing, and the "leaf green essence" can be applied at a concentration of 1000-1500 times when the seedlings are 2-3 pieces. And keep the EC value between 1.0-1.5ms/cm. Moisture: The flowering seedlings grow well under humid conditions, so try to keep the medium moist during the seedling stage. The whole plant is covered with hair. In order to avoid the spray, the plants are in a high-humidity state, and the water supply during the seedling period is carried out in a dip basin manner. The relative humidity of the air is preferably 50%. Water management depends on the principle of wetness, but it must not be done. After the radicle is grown, a 15-10-15 (N:P:K) formulation of chlorophyll 3000 times aqueous solution is applied as soon as possible, once a week. After the cotyledons are expanded, the concentration can be increased by 2000 times. The suitable temperature for the seedling stage (4-5 weeks after sowing) is 17-20 °C. The fertilization concentration is 1000-1500 times, once a week, so that the seedlings grow rapidly. Note that the EC value is kept between 1.0 and 1.5 ms/cm. If the pH of the culture soil is lower than 6.0, the plant will have severe iron poisoning and the growth will be slow or stop. Regular application of calcium nitrate avoids a drop in pH.
