Different types of flowers, due to their different seed coat structure and physiological mechanisms, the seed germination period is also different, such as a string of red, aster, Impatiens, etc. as long as timely sowing, you can quickly emerge. Some flowers need germination for months or even years, so artificial germination must be performed to shorten the dormancy period of the seeds. 1, flooding treatment. For seeds with short dormancy and easy to germinate, such as redbud, pearl plum, and garland, etc., soaking in 40 to 40 degrees of warm water for 1-2 days can be directly sowed. Torch trees and other seeds were first soaked in 90% water and allowed to cool naturally for 24 hours to soften, absorb, and germinate the colloid and waxy seed coat. However, it should be noted that when the seeds are treated with water immersion, the water must be changed frequently. The water temperature higher than 60-90 degrees should not exceed 0.5-1 hour, and then the water temperature should be reduced to below 40 degrees. Otherwise, the embryos can easily die. 2, low temperature processing. Some flower seeds, such as thorn pear, waxberry, forsythia, cloves, and some autumn sowing herbal flowers, need to be treated at a low temperature (0-10 degrees) for a certain period of time in order to promote after-ripening and break the dormancy of the embryo and germinate. The method is: mix the seeds with the sand with a temperature of 60% (that is, make a group by hand, then spread it by loosening it), then put it into a plastic bag, fasten the mouth, put it in a flower pot, and then bury the pot. In the open field of 40-60 centimeters deep, the seeds can also be placed in a refrigerator at 3 to 5 degrees for 60 to 90 days, and they can be planted in the spring. It can also be sown in the autumn to allow the seeds to pass through the natural freezing in the winter and sprout in the late spring. 3, variable temperature treatment. Some flower seeds such as tassels, pummelo, peony, peony, etc. have the habit of double dormancy of the radicle and hypocotyl, that is, the radicle (the part of the embryo that develops into the root) needs to pass for 1 to 2 months or longer The high temperature stage of 25-32 degrees can break the dormancy, and the hypocotyl needs to be released within 1-3 months under the condition of 3-5 degrees. For this type of seed, it must be mixed with wet sand before sowing. After a certain period of high temperature and then into a low temperature, after the temperature treatment, the spring sowing can germinate quickly, but care must be taken to ensure that the high temperature period and The time of the freezing period, otherwise it is still difficult for seed to emerge after sowing.
