Seed treatment method of Schisandra chinensis

After the fruit of Schisandra chinensis was ripe and harvested, the full, large and disease-free Schisandra chinensis fruit was soaked in warm water (40 ℃ 45 min) for 3 days, the pulp was rubbed, the seeds were selected, and then the blighted seeds were removed by water selection and stored in a ventilated and dry place. The method of stratification treatment is to fully mix the prepared seeds with 3 times the mass of wet sand, the humidity of the sand can not be pinched by hand, dig the potholes of 60cm × 60cm × 60cm, the thickness of the mixture of seeds and sand is 40cm, bury the soil 15cm, cover a layer of grass, press it with the soil, dig drainage ditches around to prevent Rain Water from pouring into. In this process, regular inspection to prevent seed mildew, if found that there are mold colonies can be treated with 1000 times of chlorothalonil or 1000 times of methyl topiramate spray. General stratification treatment 90Mel 120 days, see the radicle slightly exposed can be sown. If the geosyncline temperature is high during stratification, it can reach 8 ℃ 12 min and 70 mi 90 d. The seeds and sand can also be mixed and put into wooden boxes and other windows for stratification. Schisandra chinensis seed stratification should determine the temperature and time according to the sowing date, so as to avoid the phenomenon that the ground temperature of the sowing field is low and can not be sown when the radicle breaks through the seed coat after stratification, resulting in losses. The seeds of Schisandra chinensis in low-temperature wet sand accumulation can complete morphological post-ripening in a short time. In the middle and later stage of stratification, the endogenous substance inhibitory activity of Schisandra chinensis seeds was reduced and seed germination was promoted through low temperature stratification.
