Abstract
The invention discloses a method for improving the germination rate of atriplex canescens seeds. The method comprises the following specific operation steps: performing seed soaking treatment on atriplex canescens seeds by utilizing a treatment agent, and performing germination treatment on the seeds on a vermiculite substrate after the seed soaking treatment is ended, wherein the treatment agent is a sodium hypochlorite solution and/or a gibberellin solution. According to the scheme for improving the germination rate of atriplex canescens seeds provided by the invention, the germination rate of atriplex seeds can be effectively improved, and large-scale propagation of the atriplex canescens is guaranteed.
Description
Technical field
The present invention relates to woods grass cultivation field, be specifically related to a kind of method that improves Atyiplex canescen percentage of seedgermination.
Background technology
Atyiplex canescen is the units such as the vertical university in Colorado through effort for many years, and a saltbush of cultivating is improved the breed.Atyiplex canescen is the raw or mesophytes of drought, happiness light, not resistance to shade, moisture-proof not, well developed root system, annual open country shoot root can reach 3.4 meters deeply, and dark 4.6 meters of biennial root is 5 times of left and right of plant height, can not only water and soil condition preferably on the spot on growth, and can on the severe arid desert of ecotope, loess plateau and sand ground, grow, be good water and soil conservation, the seeds of pasture, improving desert, its early growth is fast, can grow into forest ahead of time; And Atyiplex canescen is also the very capable seeds of a kind of Salt And Alkali Tolerance, can in the soil of salt content 1.3%, grow, and is widely used in range improvement, water and soil conservation and alkaline land improvement etc.In addition, Atyiplex canescen nutrient component is abundant, is good feeding shrubbery, and its branches and leaves more than 12%, reach respectively 24% and 38% without N extract branch, leaf containing thick protein, have higher nutritive value.The anti-snow ability of Atyiplex canescen is strong, and after the snow of Winter-Spring, Atyiplex canescen is difficult for being buried by snow, can improve the anti-white calamity ability in pastoral area.Atyiplex canescen is bred the sub-seeding and seedling raising of can collecting seed, but Atyiplex canescen seed shell is harder, and general clear water immersion treatment germination rate is very low, germinates hardly, is therefore necessary to provide a kind of method that improves Atyiplex canescen percentage of seedgermination.
Summary of the invention
The object of this invention is to provide a kind of method that improves Atyiplex canescen percentage of seedgermination, it can effectively improve the germination rate of Atyiplex canescen seed.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of method that improves Atyiplex canescen percentage of seedgermination, concrete is operating as: utilize inorganic agent to carry out seed soaking to Atyiplex canescen seed, seed soaking finishes to be placed on vermiculite matrix and carries out germination treatment, and described inorganic agent is liquor natrii hypochloritis and/or Gibberellins solution.
When concrete operations, can adopt following two kinds of technical schemes:
One is: seed soaking, for adopting 68～72% liquor natrii hypochloritises to soak seed 9～11 minutes, is then used distilled water flushing 4～5 times.Preferably adopt 70% liquor natrii hypochloritis to soak seed 10 minutes.
It two is: seed soaking is for adopting 50～200mg/L Gibberellins solution seed soaking 23.5～24.5 hours.Preferably adopt 100mg/L Gibberellins solution seed soaking 24 hours.
Better scheme is:
Seed soaking is for first adopting liquor natrii hypochloritis once to soak seed, and rear employing Gibberellins solution or warm water carry out secondary seed soaking.Preferred: once seed soaking is for adopting 68～72% liquor natrii hypochloritises to soak seed 9～11 minutes, and secondary seed soaking is for adopting 50～200mg/L Gibberellins solution seed soaking 23.5～24.5 hours.More preferred: once seed soaking is for adopting 70% liquor natrii hypochloritis to soak seed 10 minutes, and secondary is for adopting 100mg/L Gibberellins solution seed soaking 24 hours.
In the scheme of the above-mentioned raising Atyiplex canescen percentage of seedgermination providing, first adopt inorganic agent to carry out seed soaking to Atyiplex canescen seed, then on vermiculite matrix, germinate, it can effectively improve the germination rate of saltbush seed, ensures the large batch of breeding of Atyiplex canescen.
