The invention mainly relates to the technical field of planting, and discloses a cultivation method of
selenium-enriched
toona sinensis. The method includes the steps of seed soaking, low-temperature
refrigeration,
selenium-enriched treatment and seed
germination; the method is simple, the obtained
toona sinensis is blackish green in color and luster, thick in
flavor, fresh, crisp and palatable, the
selenium content reaches 23.78 micrograms per 100 grams, the quality of the
toona sinensis is improved, and compared with traditional
toona sinensis, the
economic income of the obtained
toona sinensis is increased by 21.4%; the
toona sinensis is soaked in a dietary-alkali solution, the
softening of seed wing membranes is accelerated, the
seed dormancy is broken, the
sprouting is accelerated, and the work efficiency is improved; the low-temperature
refrigeration is conducted on seeds, the
stress resistance of the seeds is stimulated, the activities of
dormancy substances in the seeds are reduced, the
sprouting of the seeds is accelerated, and the absorption on
nutrient components is promoted; selenium-enriched
nutrient liquid is continuously sprayed on the refrigerated seeds many times, and the selenium-enriched
nutrient liquid is obtained through
fermentation and extraction, wherein the
fermentation is conducted under the effect of beer
yeast; the selenium-enriched nutrient liquid provides abundant nutrients and has anti-
bacteria and pest killing effects, the
stress resistance of the toona sinensis seeds is improved, so that the toona sinensis grows strongly, and the production efficiency is improved.
