Abstract
The invention discloses a method for improving the germination rate of aralia elata seed, which relates to a method for improving the germination rate of seed, and resolve the existing problem of the low germination rate or germination potential of aralia elata seed which is processed with accelerating ermination. The method includes the steps as follows: 1. the aralia elata seed is first soaked in water, and then in coppersulfate solution and then is washed; 2. the watered seed is mixed with wet sand and processed through low temperature cryoprecipitation, and then dried, sealed and preserved; 3. the sealed and preserved seed is taken out and then soaked in water before seeding; 4. the watered seed is mixed with wet sand and cultivated under the condition of bigger daily temperature difference to germinate, and the watered seed can be sowed. With the method, the germination rate of newly collected aralia elata seed is above 80 percent, and the germination potential is above 58 percent (7 days). The germination rate and the germination potential of the dried aralia elata seed which is processed with the method is respectively are above 75 percent and 55 percent (7 days).
Description
Technical field
The present invention relates to a kind of method that improves percentage of seedgermination.
Background technology
Aralia mandshurica another name japanese aralia bark is the perennial defoliation small arbor of Araliaceae.Be used as medicine with root, Gen Pi and leaf, edible its tender shoots, seed can extract oil.The Aralia mandshurica seed is the seed of deep dormancy type.At present,
To handle reasonable method be that earlier day alternating temperature is handled and changed 0～5 ℃ of following 4 months lamination of temperature over to when indivedual seed sprouting is arranged and handle in the vernalization of artificial treatment Aralia mandshurica seed in the production practices.Seed is that day alternating temperature stratification is handled earlier, changing the lamination of carrying out 4 months under 0～5 ℃ of temperature when treating indivedual seed sprouting over to handles, the time that seed afterripening needs was generally 5～6 months, but Aralia mandshurica is newly gathered percentage of seedgermination less than 50%, germination vigor has only about 30% (7 days time), percentage of seedgermination after do hiding then less than 40%, germination vigor is less than 15%, far do not reach the requirement of production, so people can only obtain more nursery stock with the multicast seed in producing, and have caused the serious waste of human and material resources and financial resources.
Summary of the invention
The present invention seeks to have germination rate and the low problem of germination vigor, and a kind of method that improves germination rate of aralia mandshrica seed is provided in order to solve existing vernalization processing back Aralia mandshurica seed.
The method that improves germination rate of aralia mandshrica seed realizes according to the following steps: one, the Aralia mandshurica seed was soaked 1～3 day with clear water, soaked 2～4 hours with copper sulfate solution then, the water flushing is to going out clarification of water again; Two, 1: 2 by volume～4 will wash the back seed mix with damp sand, pack into the ventilation container in, placed under 3～5 ℃ the condition cold lamination 12～16 months, the seed behind the sand of then sieve being dried placed under 15～25 ℃ the ventilation condition dry 3～5 days, placed 3～5 ℃ condition lower seal to preserve again; Three, prior to seeding 10～20 days, take out the seed that sealing is preserved, be soaked in the water 1～3 day; Four, 1: 2 by volume～4 will soak the back seed and mix with damp sand, and to place temperature difference per day be that 20～26 ℃ condition can be sowed during down to indivedual seed sprouting; Wherein the mass concentration of copper sulfate solution is 9～11g/L in the step 1; The water content of used damp sand is 70～80% in step 2 and the step 3.
The physics compounding method of application of cold temperature lamination of the present invention, drying and alternating temperature stratification has realized improving the purpose of Long Ya Aralia wood seed germination rate and germination vigor, increases the germination regularity simultaneously, shortens and come up the time; Handle the Long Ya Aralia wood percentage of seedgermination newly gather among the present invention more than 80%, germination vigor is handled the wooden percentage of seedgermination of the Long Ya Aralia of doing after hiding more than 75% in (7 days time) 58% or more among the present invention, and germination vigor is in (7 days time) more than 55%.Among the present invention in the presprouting of seeds processing procedure, do not need chemical reagent, finish the presprouting of seeds operation by the physical method that temperature and moisture are regulated, pollution-free to environment and soil, simple to operate, production cost is low, and helps to improve the resistivity of Long Ya Aralia wood seedling to sick worm infringement, is fit to production application.
