  First, the variable temperature method

  Some flower seeds such as tassels, pods, peony, etc., with the radicle and hypocotyl double sleeping habits, that is, its radicle (seed embryo develops into the root part) need 1-2 months or longer 25 ℃ -30 ℃ of high temperature phase in order to break dormancy, and under the conditions needed hypocotyl 3 ℃ -5 ℃ for 1-3 months to dormancy. For these seeds must be made before sowing, mixed with wet sand, high temperature for some time, and then transferred to a low temperature, variable temperature after treatment, spring planting can quickly germinate. However, care must be taken when handling, to ensure high-temperature and low-temperature phase of time, otherwise the seed sowing is still hard after emergence.

  Second, the flooding method

  For a short period of dormancy, the seeds germinate easily, such as Bauhinia, pearl plum, Weigela flowers, with 40 ℃ -60 ℃ warm water soaking 1-2 days can be sown directly. Torch trees and other seeds, with 90 ℃ warm water, let it cool for 24 hours, so gum, wax soften the seed coat, water, and then germinate. But note that the seed treatment to flooding when Qinhuan new water, the water temperature higher than 60 ℃ time not more than half an hour, and then the water temperature drops below 40 ℃, otherwise, embryo and easy death.

  Third, the low-temperature method

  Some flower seeds such as prickly pear, chinensis, forsythia, lilac and some autumn flowers, herbs, need to go through a certain time low temperature (0 ℃ -10 ℃) treatment, in order to break embryo dormancy and germination. Method is to seed with humidity of 60% sand (hand shape into groups, let go that is scattered) and then install a plastic bag, the mouth fastened into the pot, and then double-pots buried 40-60 cm deep open field. Seeds can also be placed within 3 ℃ -5 ℃ refrigerator 60 days -90 days, spring planting can be removed. Or open field in the autumn sowing, the seeds outdoors after natural cold of winter, germinate the following year unearthed.

  The above methods can take root and flower seedlings, flowers add some high-end spirits Four nursery to better improve the germination rate, the better.
