Abstract
The invention discloses a seedling method for promoting growing of nursery stock lateral roots and belongs to a plant breeding method. The method includes that (1) collected and mixed seeds of water oaks and apocarya are disinfected and hidden in sand; (2) germinated seeds are taken out successively in next early spring; (3) after a part of radicles of the germinated seeds is cut, the germinated seeds are transplanted into a clean sand bed, a plastic tunnel is covered on the sand bed and used for preserving heat and moisture so as to promote germinating of seed embryos and growing of radicles; and (4) when seedlings of the seeds emerge, the seedlings are transferred from the sand bed, a part of newly grown roots are cut again, and the seedings are planted in a field according to certain strain row gaps. In a sand hidden period and a germination accelerating period of forest tree seeds, measures of cutting parts of radicles of the embryos twice are taken, a large amount of lateral roots and fibrous roots are seduced to grow at the root breaking positions of seedling main roots, and the number of the lateral roots and the fibrous roots are increased by 100-350%. Increasing of root system area promotes growth and development of the seedlings, proportion of portions of the seedlings above the ground and under the ground is adjusted, and survival rate of afforestation of seedling transplanting is improved. The method has wide application and popularizing prospects in nursery stock cultivating of deep-root tree varieties.
Description
Technical field
The present invention relates to a kind of forest seeding and seedling raising technology, specifically relate to a kind of propagation method that promotes nursery stock lateral root growth seeding and seedling raising.
Background technology
The general main root prosperity of seedling of forest tree seed breeding, side, fibrous root are less.Particularly some deep-rootedness seeds, as the trees such as walnut, oak, the root length of its seedling main root is generally 1～2 times of height of seedling, and its root system is commonly called as " carrot " root; Nursery stock lateral root and the fibrous root of these type of seeds are few, and the survival rate that afforestation is transplanted is extremely low, brings huge loss to production of forestry.In prior seed seeding growing seedlings method, cut root although take to carry out a bud seedling in the time that seed sprouting is transplanted, for deep-rootedness seeds, do not change its root system and continue the characteristic of growth downwards, root system lacks flourishing side, fibrous root.
This method is chosen Fagaceae (Fagaceae) oak and is belonged to the deep-rootedness seeds such as (Quercus L.) and Juglandaceae (Juglandaceae) juglans (Juglans regia L.), cut the radicle of embryo in husky Tibetan phase of seed and vernalization phase, be completely cured by twice, can induce the place of being completely cured newborn a large amount of lateral root and the fibrous root of seedling main root, promote seedling to form I, II level side, the fibrous root root system of prosperity, compactness, adjust nursery stock ground and underground ratio, improve Nursery stock transplanting survival rate.
Summary of the invention
Goal of the invention: the object of this invention is to provide a kind of seedling-cultivating method that promotes nursery stock lateral root growth.Cut at twice the radicle of embryo in husky Tibetan phase of forest tree seed and vernalization phase, can induce and promote the place of being completely cured of seedling main root newly to bear I, II level lateral root and fibrous root, form the root system of luxuriant prosperity, compactness, adjust nursery stock on the ground and underground ratio, improve Nursery stock transplanting survival rate.
Technical scheme: for achieving the above object, a kind of nursery stock lateral root growth seeding growing seedlings method that promotes of the present invention, comprises the steps:
(1) by husky Tibetan after the water oak that gathers, modulates, apocarya seed disinfection;
(2) the husky seed of hiding of leafing through early spring in next year, takes out the seed germinateing successively.For subsequent use;
(3) step (2) chitting piece is cut off after radicle sterilization, transplanted in clean husky bed, the upper plastic covering shed insulation of husky bed, moisturizing, to promote the sprouting of seed plumule and the growth of radicle;
(4) when transplanting in needing before field after " hardening " after step (3) seed sprouting, then it is shifted out and be colonizated in large Tanaka from husky bed.
Wherein, step (1) is seed disinfection and Sha Zang, and the method can effectively suppress to cause growing of the pathogens such as nursery stock damping off, keeps the vigor of seed germination;
Step (2) picks that radicle stretches out and root reaches seed more than 3～5cm in time;
Step (3) cuts 1/3～1/2 of seed base-root for the first time, promotes the embryo sprouting of being completely cured out to grow I level lateral root;
Step (4) cuts 1/2～2/3 of seedling I level lateral root for the second time, promotes the sprouting of II level lateral root.
Beneficial effect: the present invention is in husky Tibetan phase of forest tree seed and vernalization phase, by cutting the measure of embryo radicle for twice, can induce the place of being completely cured newborn a large amount of lateral root and the fibrous root of seedling main root, side, fibrous root number are more once cut root and are increased 100%～350%, the increase of surface area of root systern has promoted growing of seedling, adjust nursery stock ground and underground ratio, improve Nursery stock transplanting survival rate.The method, in the cultivating seedlings of deep-rootedness seeds, has a wide range of applications and promotion prospect.
