Description
Technical field
The invention belongs to agricultural plantation technology fields, and in particular to a kind of method for culturing seedlings of sweet osmanthus.
Background technology
Sweet osmanthus is the flower that people extremely like, and has the good reputation of ten big famous flowers.China sweet osmanthus in 1771 through Guangzhou,
India is passed to Britain, is hereafter rapidly developed in Britain.Many countries American-European now and Southeast Asian countries have cultivation, development ten
Divide rapidly, however the rest period of fragrans seed is long, can go mouldy if preservation is improper, germination percentage is caused to reduce.Seed
It is fettered with hard kind shell, again containing higher germination inhicbitor, and there is one layer of colloid in seed in kind shell, is not easy to absorb
Moisture, the emergence rate of sowing in the field seed is very low, so the dormancy time for breaking seed is very necessary.
Fashion is increasingly becoming using flowers as a kind of new cuisines raw material in recent years, to flower nutrition product Quality Research
Gradually carrying out.Not only contain volatile oil in sweet osmanthus, at the same also containing the nutrition such as mineral element, protein and amino acid into
Point, it is edible, medicinal and for health care etc., it is the edible treasure of ecosystem.Therefore the nutritional quality for improving sweet osmanthus is equally to be promoted
The effective means of planting benefit.
The content of the invention
The purpose of the present invention is being directed to the problem of existing, a kind of method for culturing seedlings of sweet osmanthus is provided, is not only effectively increased
The emergence rate of fragrans seed, while the sweet osmanthus finished product seedling quality educated is good, the sweet osmanthus nutritive value brought out is high, great promotion price
Value and the market competitiveness.
The present invention is achieved by the following technical solutions：
A kind of method for culturing seedlings of sweet osmanthus, includes the following steps：
（1）Seed selection and processing：
Full grains, no disease and pests harm, the seed having no mechanical damage are selected, after removing exocarp and pulp, then seed is put into
20 ~ 25min of homogenization in homogenizer takes out after drying, then seed is put into immersion treatment in seed treatment liquid after finishing
40 ~ 45min takes out spare after finishing；
（2）Vernalization is handled：
By step（1）Treated, and fragrans seed is put into progress vernalization processing in germinating box, is taken out after 5 ~ 8h spare；
（3）Seed is sowed and management：
By step（2）Treated, and seed is seeded on seedling bed carries out seedling management, when seedling grows 2 ~ 3 true leaves, is opened
The addition sprinkling for beginning to carry out foliar fertilizer is handled, and is carried out at the same time x ray irradiation x processing, until seedling grows 8 ~ 9 true leaves；Afterwards again
Finished product sweet osmanthus seedling is cultivated into according to a conventional method.
Further, step（1）Described in homogenization when control the pressure in homogenizer to be for 8 ~ 10MPa, temperature
45~50℃。
Further, step（1）Described in seed treatment liquid by following parts by weight material composition：3 ~ 5 parts of gibberellin,
1 ~ 3 part of brassinosteroid, 15 ~ 20 parts of glucose, 4 ~ 8 parts of urea, 1000 ~ 1200 parts of water.
Further, step（1）Described in immersion treatment when heating keep seed treatment liquid temperature be 40 ~ 45 DEG C.
Further, step（2）Described in vernalization processing when control temperature in germinating box as 33 ~ 36 DEG C.
Further, step（3）Described in foliar fertilizer additional sprinkling processing and x ray irradiation x processing carry out daily
Once, fountain height per acre is controlled when wherein foliar fertilizer sprinkling is handled, and for 30 ~ 35kg, x ray irradiation x processing is to utilize60Co- γ are penetrated
Line carries out radiation treatment, the when a length of 3 ~ 4h irradiated every time, and the dosage rate of irradiation is 0.5 ~ 1.0Gy/min, the foliar fertilizer by
The material composition of following parts by weight：4 ~ 6 parts of γ-aminobutyric acids, 30 ~ 50 parts of glucose, 2 ~ 4 parts of magnesium sulfate, 5 ~ 8 parts of fulvic acids
