Technical field
The present invention relates to seed processing technology field, in particular it relates to a kind of cotton seed germination accelerator.
Background technology
Cotton in China produces at the forefront in the world, is weaving big country and maximum Cotton Gossypii country of consumption, the whole nation have 23 provinces, city,
Autonomous region produces Cotton Gossypii, and Cotton Industry occupies critical role in national economy.The major-minor product of Cotton Gossypii has higher utilization
Being worth, as described in forefathers " Cotton Gossypii whole body is all precious ", it is most important fibre crops, is again important oil crop,
Also it is the cereal crops containing high protein, or weaving, fine chemical material and important strategic materials.Therefore, it is necessary to make great efforts to make
Yield Increase In Cotton, does comprehensive utilization well, increases both production and value, to increase cotton grower's income and to meet the many needs of the national economic development.
In recent years, while global climate slowly gradual warms up, extreme climate change frequency increases, uneven in temperature, causes
The chilling injury such as freeze injury, frost damage takes place frequently, and causes the emergence rate of Cotton Gossypii and planting percent to reduce；On the other hand, in order to maximize profit
With sunlight-heat reaources and expansion cotton growing stage, people have employed the technical measures such as Plastic Film Mulch cotton, make gradually carry the sowing time of Cotton Gossypii
Early, but spring temperature change instability, Cotton Production is brought serious harm by " cold spell in later spring ", and low temperature cold wet environment causes Cotton Gossypii
Emergence difficult, rotten kind, rotten, be short of seedling disconnected ridge, and serious even ruins kind of a replay, and this not only affects output of cotton and improves further,
And causing cotton quality degradation, low temperature is to affect one of key factor that Cotton Gossypii emerges.
Seed priming is at a kind of seed controlling seed germination that a biological mechanism based on seed germination proposes
Reason technology, is mainly achieved the goal by aspects such as Osmoregulation, temperature regulation, gas regulation and hormonal regulation.Numerous studies
Showing, seed priming can improve seed vitality, can accelerate to send out under the adverse environmental factors such as low temperature, high temperature, arid, salting or hypoxia
Bud, improves germination concordance and emergence rate and planting percent.
