Abstract
The invention discloses a method for promoting the germination of quercus rubra seeds, belonging to plant breeding methods. The method comprises the following steps: (1) performing modulation pretreatment on seeds for later use; (2) performing chemical reagent stimulation; and (3) disinfecting the seeds, and then preserving the seeds in sand or directly sowing the seeds. According to the method disclosed by the invention, the seeds are treated by using chemical reagents at high temperature to ensure that diseases and insect damages of red oak seeds can be significantly reduced, the dormancy of the quercus rubra seeds can be broken, the seeds can be promoted to germinate 30-40 days in advance, the germination rate can be increased by 15-20%, a working procedure that the seeds can only germinate by virtue of necessary low-temperature treatment can be omitted, and the working efficiency can be increased by 30-50% compared with that when a conventional germination accelerating process is adopted; and moreover, the growth cycle of seedlings can be prolonged.
Description
Technical field
The present invention relates to a kind of woody plant raising technology, specifically relate to the method promoting the red oak seed germination in North America.
Background technology
The red oak in North America (Quercus rubra), also known as yellow jacket tree, is that Fagaceae (Fagaceae) oak belongs to (Q.L.) seeds.Robur adaptability is very strong, and its wood quality is excellent, and decorative pattern is beautiful, and oak is internationally famous top grade preciousness material.Red oak originates in the U.S. in North America, and China has carried out systematic study on introduction the nineties, and in Zhejiang, Jiangsu, the ground such as Jiangxi and Shanghai tests, and obtains good result.North America red oak growth is fast, and tree-like grace, the beautiful ornamental value of red autumnal leaves in autumn is high, is widely used in the afforestation of town and country.At present, breeding based on seed propagation of these seeds, conventional seed planting seedling-cultivating method is directly broadcasted sowing in soil by seed, because red oak seed has hibernation feature, need could normally to sprout after the cold wet condition process of about 3 months, in soil pathogen and soil insect more, the factors such as soil aeration is poor in addition, cause sowing nursery germination percent of seed in soil extremely low; In addition, the red oak seed in North America mostly is import, and seed profile is comparatively large, and the direct cost of 1 seed is at about 2 yuan, and seedling cost is very high, and traditional seedling-cultivating method is produced to achievements in forest-tree seedling and brought loss.This method be by red for North America oak first through hot-water soak, kill causing harm of the real weevil of red oak kind, then use (CS (NH
2)
2) remove the dormancy of red oak seed, seed, without the need to through long-time cold wet process, directly can sow germination.This method reduce causing harm and nursery operation and cost of oak weevil, promote that seed germinates ahead of time, improve percentage of seedgermination, extend the growth cycle of nursery stock, in North America red oak nursery is produced, there is important directive significance.
Summary of the invention
Goal of the invention: the object of this invention is to provide promote North America red oak seed germination method, significantly reduce causing harm of oak weevil, promote that seed germinates ahead of time, improve germination rate, extend the growth cycle of red oak nursery stock, reduce nursery stock production operation and cost.
Technical scheme: promote that the method concrete steps of North America red oak seed germination are as follows:
(1) gather the seed of the red oak maturation in North America October in autumn ~ November, or in the seed of purchase in early spring in next year, reject and go rotten and after damaged seed, pull out after being placed in the hot water immersion 30 ~ 40m of 45 ~ 50 DEG C and dry in the shade.For subsequent use;
(2) by the seed chemical reagent stimulation process of step (1).For subsequent use;
(3) by step (2) seed through 0.5% (CuSO
4.5H
2o) after sterilization, evenly sowing, in husky bed, is not superposed to suitable with seed mutually.The insulation of plastic covering shed, moisturizing on husky bed, to promote the sprouting of seed;
Wherein, step step (2) described seed chemical reagent stimulation process refers to 2 ~ 3% (CS (NH of the seed after by modulation treatment
2)
2) aqueous solution soaking 8 ~ 12h after, then to rinse well with clear water.
Beneficial effect: the present invention be by red for North America oak first through hot-water soak, kill the causing harm, with 0.5% (CuSO of the real weevil of red oak kind
4.5H
2o) disinfection seed can not lose embryo, then uses (CS (NH
2)
2) remove the dormancy of red oak seed, seed, without the need to through long-time cold wet process, directly can sow sprouting.This method reduce causing harm and nursery operation and cost of oak weevil, promote that seed is done sth. in advance 30 ~ 40d and germinateed, germination rate improves 15% ~ 20%, extends the growth cycle of nursery stock.
