Abstract
The invention discloses a naked stratification method for Acer mono seeds, which relates to a stratification method for seeds. The method disclosed by the invention is designed for solving the technical problem that in the existing Acer mono seed stratification process, seeds are germinated in advance, seeds after being sown are sprouted irregularly, and the sowing time is strictly restricted. The method disclosed by the invention comprises the following steps of: 1, soaking Acer mono seeds into clear water, replacing water every day, soaking the soaked seeds by using a potassium permanganate solution so as to carry out disinfection on the seeds, and then rinsing the seeds by using clear water; and 2, naked stratification: placing the Acer mono seeds rinsed in the step 1 at a temperature of 3-5 DEG C for 24-32 weeks so as to carry out naked stratification on the seeds, in the previous 21-27 weeks of naked stratification, controlling the relative water content of the seeds to be 45-50%, and in the last 3-5 weeks of naked stratification, controlling the relative water content of the seeds to be 35-40%, so that the naked stratification of Acer mono seeds is completed. The method disclosed by the invention facilitates the improvement of the sowing and seedling-raising effects of Acer mono seeds, and is applicable to the field of seed stratification.
Description
Technical field
The present invention relates to the germination accelerating method of seed.
Background technology
The traditional seed dormant method of releasing of look wood maple has the mixed sand bed of low temperature to amass, survive the winter and the lamination processing method such as bury.The mixed sand bed of low temperature amasss or the burying storage of surviving the winter can make seed first green sprouting after maturation, but germination rate is low, emerges irregular.If in the lamination process, do not control environmental temperature well, have a large amount of seeds and rot or sprout in advance and cause huge economic loss.Removing look wood maple seed dormancy needs the plantsman to carry out the vernalization processing in the fixed time period in every year, dormancy-broken seeds must be sowed in predetermined time, if run into the extreme weather situations such as high temperature, wet weather at seeding time and incur loss through delay, dormancy-broken seeds can not the sowing in time meeting constantly descend even death seed vitality, thereby affects nursery effect.
Summary of the invention
The present invention will solve in the present look wood maple earthing of seeds processing procedure to sprout in advance, after planting germinates uneven, and the sowing time is subject to the technical problem of strict restriction, thereby provides a kind of look wood maple seed naked lamination germination accelerating method.
The naked lamination germination accelerating method of a kind of look wood maple seed of the present invention is to carry out according to the following steps:
One, look wood maple seed was soaked 2～3 days with clear water, change water every day 1～2 time, with the potassium permanganate solution soaking disinfection 1～2h of the seed after soaking with 5～10g/L, then rinse well with clear water;
Two, naked lamination is processed: the look wood maple seed after step 1 is rinsed well is placed in 3～5 ℃ and is carried out naked lamination processing 24～32 weeks, the relative water content of front 21～27 weeks control seed that naked lamination is processed is 45%～50%, when naked lamination processing finishes front 3～5 week, the relative water content of control seed is 35%～40%, namely finishes the naked lamination vernalization of look wood maple seed;
Wherein, relative water content refers to that contained humidity amount in the seed accounts for the percentage of seed gross weight.
The present invention includes following beneficial effect:
1, the present invention's seed in the lamination processing procedure is not puddled with any matrix, the method of temperature and water content in naked lamination, the control lamination process used has realized the in advance sprouting of look wood maple seed, and increase the germination regularity of look wood maple seed, to dormancy-broken seeds again dry storage with the purpose of sowing at any time;
2, the present invention does not need chemical reagent in the presprouting of seeds processing procedure, finishes the presprouting of seeds operation by the physical method that temperature and moisture are regulated, and is pollution-free to environment and soil, simple to operate, is fit to production application;
3, production cost of the present invention is low, method is simple, easy to operate, easily promote, help to improve the seeding and seedling raising effect of look wood maple seed, be fit to use in the production practices.
Embodiment:
Embodiment one: the naked lamination germination accelerating method of a kind of look wood maple seed of present embodiment carries out according to the following steps:
One, look wood maple seed was soaked 2～3 days with clear water, change water every day 1～2 time, with the potassium permanganate solution soaking disinfection 1～2h of the seed after soaking with 5～10g/L, then rinse well with clear water;
Two, naked lamination is processed: the look wood maple seed after step 1 is rinsed well is placed in 3～5 ℃ and is carried out naked lamination processing 24～32 weeks, the relative water content of front 21～27 weeks control seed that naked lamination is processed is 45%～50%, when naked lamination processing finishes front 3～5 week, the relative water content of control seed is 35%～40%, namely finishes the naked lamination vernalization of look wood maple seed.
Present embodiment comprises following beneficial effect:
1, present embodiment seed in the lamination processing procedure is not puddled with any matrix, the method of temperature and water content in naked lamination, the control lamination process used has realized the in advance sprouting of look wood maple seed, increase the germination regularity of look wood maple seed, to dormancy-broken seeds again dry storage with the purpose of sowing at any time;
2, present embodiment does not need chemical reagent in the presprouting of seeds processing procedure, finishes the presprouting of seeds operation by the physical method that temperature and moisture are regulated, and is pollution-free to environment and soil, simple to operate, is fit to production application;
3, the production cost of present embodiment is low, method is simple, easy to operate, easily promote, help to improve the seeding and seedling raising effect of look wood maple seed, be fit to use in the production practices.
Embodiment two: what present embodiment and embodiment one were different is: the seed of look wood maple seed for newly gathering in the step 1.Other is identical with embodiment one.
Embodiment three: what present embodiment was different from embodiment one or two is: the relative water content of the front 25 weeks control seed that naked lamination is processed in the step 2 is 46%～49%.Other is identical with embodiment one or two.
Embodiment four: what present embodiment was different from embodiment one or two is: when the lamination processing finished front 3 week, the relative water content of control seed was 36%～38% in the step 2.Other is identical with embodiment one or two.
By following verification experimental verification beneficial effect of the present invention:
Test one: the naked lamination germination accelerating method of a kind of look wood maple seed of this experiment is to realize according to the following steps:
