Description
Technical Field
The invention belongs to the technical field of litsea cubeba cultivation, and particularly relates to a method for efficiently treating litsea cubeba seeds.
Background
Litsea cubeba, also named litsea cubeba, alpinia japonica, cinnamomum komarovii, deciduous shrubs or small trees of the genus litsea of the family Lauraceae, up to 8-10 meters, greenish yellow bark of young trees, smoothness, and grey brown bark of old trees. Pungent, slightly bitter, fragrant and nontoxic. The litsea fruit is a raw material tree for producing litsea oil, extracting citral and manufacturing special essence. As the special essence is in stock and price shortage in markets at home and abroad, the price of the litsea pungens is doubled, and the market gap is large. Therefore, the artificial planting of the litsea cubeba is one of the important ways for farmers to create income and enrich in hills and mountainous areas. The litsea cubeba is one of the special spice plant resources in China, the annual output of litsea cubeba oil in China reaches more than 2000 tons, the litsea cubeba oil is the largest producing country and export country in the world, the annual export amount reaches about 3500 tons, and the products are sold in America, Japan, English, French, Germany, Switzerland, Holland and other countries and enjoy the reputations of China and abroad.
The seed seedling culture is the most main breeding method of the litsea pungens at present, but the litsea pungens have long dormancy period and extremely slow germination, and the seeds need to germinate individually about 50 days after sowing, so that the duration time is very long and can reach two years; the cortex of the litsea pungens seed is thick and hard, the wax layer is attached to the seed coat, so that the litsea pungens seed is waterproof and airtight, and the seed contains substances for inhibiting seed germination, so that the dormancy period of the litsea pungens seed is long, the seed germination is difficult, and the germination rate and the emergence rate are low, therefore, the litsea pungens seed needs to be treated to a certain extent before sowing, so that the dormancy is released, the seed germination is started, the germination rate and the emergence rate are improved, and experiments prove that the germination rate of the litsea pungens seed without treatment is only 7.2%.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide a method for efficiently treating litsea pungens seeds, which can effectively reduce or remove substances contained in the seeds for inhibiting seed germination, release dormancy of litsea pungens seeds, promote germination of litsea pungens seeds, and effectively increase germination rate and emergence rate.
The specific technical scheme is as follows:
a method for efficiently treating litsea seeds comprises the following steps:
s1, seed moistening: putting the litsea pungens seeds into 5% potassium permanganate solution, putting the litsea pungens seeds into a refrigerating chamber with the temperature of 0-3 ℃, soaking the litsea pungens seeds for 6-12 minutes, taking the litsea pungens seeds out, washing the litsea pungens seeds with low-temperature water at the temperature of 0-3 ℃ and then washing the litsea pungens seeds with water at the temperature of 40-50 ℃;
s2, dewaxing: taking out the seeds after seed moistening, mixing the seeds with soapy water, fly ash and river sand with the particle size smaller than that of the seeds according to the proportion of 1: (1-3): (2-6): (3-7), putting the mixture into a stirrer, uniformly stirring the mixture for 30-60 minutes, and taking out the mixture; putting the mixture on a screen of a vibrating screen to screen out fly ash and river sand, and then washing the mixture clean by warm water;
s3, dormancy breaking: taking out the dormancy releaser and washing the dormancy releaser clean for later use; the dormancy releaser is disc-shaped, and a plurality of water outlets are uniformly formed in the periphery of the bottom of the outer wall of the dormancy releaser; a drainage groove with a drainage notch is annularly arranged on the outer wall of the dormancy eliminator, and the bottom of the drainage groove is lower than the upper surface of the dormancy eliminator; a cylinder is vertically arranged in the middle of the upper surface of the dormancy eliminator, crushed ice blocks are arranged in the cylinder, and a plurality of water outlet holes communicated with the dormancy eliminator are formed in the periphery of the bottom of the cylinder; uniformly mixing the seeds treated in the step S2 with river sand, and putting the mixture into a dormancy eliminator; then the crushed ice is put into a cylinder at the middle part of the dormancy releaser; standing at normal temperature until the crushed ice is completely melted, supplementing the crushed ice into the cylinder again, and then supplementing for 2-5 times; after the crushed ice is melted, the generated ice water flows into the dormancy eliminator from the bottom of the cylinder to continuously infiltrate the seeds and then flows out of a water outlet on the outer wall of the dormancy eliminator, the concentration of abscisic acid in the seeds is reduced when the seeds are infiltrated by the ice water at low temperature, the relative concentration of gibberellin is increased, so that the seeds are in contact dormancy to promote the germination of the seeds;
s4, screening: after step S3 is completed, the mixture of seeds and river sand is taken out; screening out river sand to obtain seeds which finish dormancy breaking;
s5, sterilization: and (5) washing the seeds obtained in the step (S4) with clear water, draining, and sterilizing by ultraviolet irradiation to finish the pretreatment of seed sowing.
Further, in the step S2, the ratio of the seeds to the soapy water to the fly ash to the river sand is 1:3:2: 3.
Further, the soap water in the step S2 is obtained by uniformly mixing soap powder and warm water according to the proportion of 1: 10.
Further, the river sand used in step S3 has a grain size of one third to one half of the seed grain size.
The method is simple to operate, and the steps of moistening seeds, dewaxing, dormancy relieving and the like are sequentially performed, so that substances inhibiting seed germination in the seeds are effectively reduced or removed, the dormancy of the litsea cubeba seeds is relieved, and the germination rate and the emergence rate of the litsea cubeba seeds are effectively improved by promoting the germination of the litsea cubeba seeds.
