Abstract

The invention relates to a method for germinating Araliaceae seed and keeping Araliaceae seed fresh. Wherein, it comprises (a), collecting seed at September while berry is black; (b), adjusting seed that first stacking collected seeds for 3-5 days then braking seeds via rolling method when stacking 3-5 days, poaching, taking out, drying, removing bore hole, and weighting; (c), treating seeds that adding activol to prepare the seed emerge solution whose density is 50-100mg/kg, and emerging the adjusted fresh seed in emerge solution for 1-2 hours, taking out and washing with water, and drying to make the humidity at 50-55%; mixing seed and sand uniformly, and using carbendazol and atomizing to disinfect, and making the humidity at 45-55%; putting it at 10-17Deg. C, after 20-60days, putting it at -1-5Deg. C for 40days, until seeding. The invention has short time and low cost.

Description

Fresh-keeping germination hastening method for araliaceae seed

Technical field

The present invention relates to method for treating seeds, be specifically related to the germination hastening method of araliaceae seed.

Background technology

Araliaceae is the rare economic plants in forest zone, northeast as wilsonii, Aralia mandshurica, thorn genseng, and diversified economy is worth to have very high edible, medicinal, industrial processes, view and admire etc.Because people freely excavate utilization since the history, the fast development of processing industry in recent years becomes multiple to increase progressively to wilsonii, Aralia mandshurica, the raw-material demand of thorn genseng year by year, to wild resource is fallen sharply year by year, and edge so far in imminent danger.For realizing the sustainable use of such species, make the artificial breeding cultivation extremely urgent.The Araliaceae seed has idiosome dormancy biological nature, and embryo does not break up fully during its seed maturity, is in the proembryo shape, and the nutrition continued growth that also need absorb in the endosperm is grown and could be sprouted.Even the Araliaceae seed is in sufficient nutrient under the natural conditions, suitable humidity, temperature, also 2 years ability of needs is germinateed under enough oxygen conditions, therefore under the natural ecological condition, rarely found Araliaceae seedling, saying of " 10 years difficulties of wilsonii being seen seedling " arranged as before, so, the relatively difficulty of presprouting of seeds processing of growing seedlings of growing directly from seeds.At present, the method that araliaceae seed vernalization handle is adopted is that the seed after drying in the shade adopts alternating temperature stratification to handle, and promptly high temperature～low temperature changes, and high-temperature control is at 17～19 ℃, and about about 90～110 days, low temperature was controlled at-1～-5 ℃, about 70 days.This method for treating seeds is relatively stricter to temperature requirement, and accumulated temperature is higher; Seed collection, modulation seed to seed are dried in the shade, arrive the seed alternating temperature again and handle, the processing time is long, and the easy infection mould when seed treatment quantity is big, is difficult in the production satisfy above-mentioned condition, even reach requirement, production cost is also higher.As adopt alternating temperature stratification to handle after stinging ginseng seeds and drying in the shade again, and almost all dead, seldom emerge.

Summary of the invention

The purpose of this invention is to provide the fresh-keeping germination hastening method for araliaceae seed that a kind of processing time is short, expense is low.

Technique effect of the present invention is: the present invention helps embryo differentiation according to fresh-keeping seed high temperature, low temperature helps the seed physiology after-ripening principle of embryo elongation, reaches embryo completion morphology and physiology after-ripening.This method is handled the direct lamination of the fresh-keeping seed in modulation back, has saved seed and has dried in the shade the time, saves disposal cost; And soak seed with gibberellin, and break seed dormancy, help the embryo differentiation, can stimulate fat, polysaccharide and the protein transduction preserved in the seed to turn to sugar, movably amino acid and acid amides.Than conventional treatment method processing time shortening about 60 days, save disposal cost 1/3, the seed treatment effect reaches the conventional treatment peer-level, produces to be easy to hold.

Purpose of the present invention is achieved through the following technical solutions:

(a), seed collection

Select robust growth, completely filled fruit, the suitable local harmful provenance collection of no parasitosis.The seed collecting time gathered when September, berry was pitchy.

(b), seed modulation

At first stack retting after 3～5 days with rub the stone roller method with the berry breakage after, rinsing in clear water is pulled the seed that sinks under water out control and is done, treat that kind of skin is air-dry after, adopt methods such as picking, selection by winnowing again, remove empty flat small holes caused by worms kind grain, weigh.

(c), seed treatment

At first add the warm water of gibberellin about 40 ℃, compound concentration is the seed-soaking liquid of 50～100 mg/kg, the fresh seeds that modulates is immersed in the seed-soaking liquid, seed and seed-soaking liquid mass ratio 1: (1～2), promptly 100 jin of seeds are immersed in 100～200 jin of seed-soaking liquids, soaked 1～2 hour, and pulled out with after the flushing with clean water one time and control water, make seed humidity 50%～55%.Again by seed and sand volume ratio 1: puddle evenly (3～5), sand is the pure river of middle grain sand, by carbendazim and water quality than 1: (600～1000) are diluted to 600～1000 times of liquid of carbendazim, with carbendazol spray disinfection sterilization while puddling, make kind of sand humidity 45%～55%.Sprayed kind of sand once with 600～1000 times of liquid of carbendazim in per 7 days later on, keep kind of sand humidity 45%～55%, place under 10 ℃～17 ℃ conditions, air circulation is good, in the few environment of assorted bacterium, control taking-up before sowing more than 40 days in the few environment of good, the assorted bacterium of low temperature, the air circulation that after 20～60 days, promptly changes-1～-5 ℃ over to.During sowing with broadcasting with getting.

Specific embodiment

The fresh-keeping germination accelerating method of wilsonii seed early and middle ten days in September wilsonii berry becomes black by green, can gather this moment, stack retting is rubbed with hand after 3～5 days or is smashed to pieces gently with wooden stick, berry is separated with seed, and rinsing in clear water is pulled the seed that sinks under water out control and is done, after treating that kind of skin is air-dry, carry out methods such as picking, selection by winnowing again, remove empty flat small holes caused by worms kind grain, weigh.At first adding the warm water compound concentration of gibberellin about 40 ℃ is the seed-soaking liquid of 50～100 mg/kg, seed and seed-soaking liquid mass ratio 1: 1, promptly 100 jin of seeds are immersed in 100 jin of seed-soaking liquids, soak 1.5 hours, pull out with after the flushing with clean water one time and control water, make seed humidity 50%～55%.Puddle at 1: 3 evenly by seed and medium sand volume ratio again,, plant sand humidity 45%～55% with the spray disinfection sterilization of 800 times of liquid of carbendazim while puddling.Sprayed kind of sand once with 800 times of liquid of carbendazim in per 7 days later on, keep kind of sand humidity 45%～55%, place under 10 ℃～17 ℃ conditions, air circulation is good, in the few environment of assorted bacterium, control taking-up before sowing more than 40 days in the few environment of good, the assorted bacterium of low temperature, the air circulation that after 60 days, promptly changes-1～-5 ℃ over to.
