Abstract
The invention discloses a seed treatment method for improving quality of goldenrain tree seedlings and provides a whole set of seed treatment measure from seed harvesting and storage to treatment before seeding, in particular to a seed germination method with physical treatment and chemical treatment. Compared with a traditional method, the seed quality of goldenrain trees is obviously increased, the emergence rate is greatly increased, the quality of growing seedlings is excellent, the defect that a traditional goldenrain tree seed difficultly germinates is overcome, troubles during goldenrain tree planting are reduced, good seedlings are provided for afforestation, and a practical value is obvious.
Description
Technical field
The present invention relates to the planting technology of Luan Shu, especially relate to a kind of method for treating seeds improving Luan Shu nursery stock quality.
Background technology
Luan Shu resists cold drought-enduring, cultivation manageability, and normal cultivation views and admires tree as flower garden, and Luan Shu can obtain through refining tannin extract in addition, and flower can make weld, and seed can extract oil, and timber yellow-white, easily processes, can furniture processed; Leaf can make blue dyes, and flower hyoscine, also can make weld; The multiple utilities of trees different parts makes Luan Shu have higher ecology and economic worth.
Seeding and seedling raising remains the main mode that current goldenrain tree tree planting adopts, and the quality of seed directly has influence on the quality of trees, and the process of seed is the basis ensureing seedling quality.And the seed coat of Luan Shu is hard not easily permeable, as without dealing carefully with, Second Year is sowed in spring and is not often germinateed, also cause Luan Shu seed wastage large because its seeding ratio is low, trees quality of emerging is very different especially, bringing a lot of trouble to the cultivation management of Luan Shu, being worth research as provided a kind of effective method for treating seeds.
Summary of the invention
Goal of the invention: in order to solve in prior art the low and uneven problem of seedling quality of existing Luan Shu trees emergence rate, the present invention proposes the method for treating seeds of a kind of effective raising emergence rate and seedling quality.
Technical scheme: to achieve these objectives, the present invention takes following technical scheme: a kind of method for treating seeds improving Luan Shu trees quality, comprises the steps:
(1) collect seed: acquisition time selects late September to early October, select life in-15 years in 10 years to physically well develop, lead to straight without damage by disease and insect, form, tree crown is open, the maternal plant of completely filled fruit, when the non-full maturity of fruit, namely carry out gathering of fruit, after gathering, in 12-24h, remove pericarp, isolated seed is got clean water soaking 2-4d and increases 5%-10% to seed weight, take out nature dry in the shade to 8 one-tenths dry;
(2) storage of seed: get glass open-top receptacle, sand is poured at bottom, the stone that the salt acid soak covering one deck mass fraction 0.5% above sand is crossed, is layered on stone with gauze, by above-mentioned air-dry after seed be layered on gauze, one deck sand is covered again on seed, cladding thickness is 3-5cm, and sand covers one deck gauze again, the wooden sealing of lid of vessel port, be placed in refrigerator temperature to remain on-5-0 DEG C and place after 20-30d, after taking out, 0-10 DEG C of husky Tibetan stores;
(3) physical treatment before sowing: 8-15d before sowing, seed is taken out from sand, with screen cloth to be separated with sand rear be first placed in sunlight under to be exposed to the sun 2-3h, shrivelled seed is removed with clear water drift, with file, seed coat is poked, be wrapped in gauze, be placed in take out after 45-50 DEG C of water soaks 20-30min and repeatedly wash 10-15min by rubbing with the hands, remove the mucous membrane under stranding with water drift, continue after 25-35 DEG C of incubator dries to be placed in interior 15-20 DEG C of storage;
(4) chemical treatment before sowing: 3-6d before sowing, get chloroform 2-5 part in mass, tartaric acid 3-6 part, sodium citrate 5-8 part, sodium bicarbonate 6-15 part, concentrated sulfuric acid 10-20 part and ash 8-15 part preparation mixed solution, the seed stored in step (3) is taken out, be placed in mixed solution soak 4-8h after after taking-up water rinse 3-5 time natural air drying to 8 become the dry gauze that is placed on to wrap up storing and wait to sow.
More preferred, the fruit of gathering in described step (1) chooses the uncracked fruit of dark brown, in case fruit is not gathered just drop to ground, ensures the freshness of seed.
Further, the removal of described step (1) mesocarp should be carried out under 20-25 DEG C of room temperature.
More preferred, in described step (2), the particle diameter of stone is 1-3cm.
More preferred, in described step (2), the soak time of stone in hydrochloric acid is 12-24h.
More preferred, in described step (2) container fill seed and sand mixture is no more than 2/3rds of container capacity.
More preferred, the frequency of washing by rubbing with the hands of washing seed in described step (2) by rubbing with the hands is no more than 200 times/min.
More preferred, when soaking in described step (4), temperature is 40-45 DEG C.
More preferred, the water that in described step (4), rinsing adopts is deionized water.
Beneficial effect: a kind of method for treating seeds improving Luan Shu nursery stock quality provided by the invention, propose a set of from the gathering of seed, be stored into a whole set of seed treatment measure of the process before sowing, especially presprouting of seeds adopts physical treatment to hold concurrently chemical treatment method, comparatively conventional method, significantly improve the seed quality of Luan Shu, emergence rate increases substantially, and the nursery stock product grown are of fine quality, overcome the easy ablastous drawback of traditional Luan Shu seed, decrease the trouble existed in goldenrain tree tree planting, for its afforestation provides the nursery stock of high-quality, practical value is remarkable.
