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 of the seedling of forest tree seed breeding is flourishing, and side, fibrous root are less.Some deep-rootedness seeds particularly, like trees such as walnut, oaks, 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 and is " 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 tremendous loss to production of forestry.In the prior seed seeding growing seedlings method, cut root though take when seed sprouting is transplanted, to carry out a bud seedling, for the 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 (Quercus L.) and Juglandaceae (Juglandaceae) juglans deep-rootedness seeds such as (Juglans regia L.); Cut the radicle of embryo in husky Tibetan phase of seed and vernalization phase; Be completely cured through twice, can induce the place of the being completely cured newborn a large amount of lateral root and the fibrous root of seedling main root, promote seedling to form prosperity, compact I, II level side, fibrous root root system; Adjustment nursery stock ground and underground ratio improve the Nursery stock transplanting survival rate.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide a kind of seedling-cultivating method that promotes the nursery stock lateral root growth.Cut the radicle of embryo at twice 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, adjustment nursery stock ground and underground ratio improve the Nursery stock transplanting survival rate.
Technical scheme: for realizing above-mentioned purpose, a kind of promotion nursery stock lateral root growth seeding growing seedlings method of the present invention comprises the steps:
(1) the husky Tibetan after the water oak that will gather, modulates, the apocarya seed disinfection;
(2) the husky seed of hiding of leafing through early spring in next year takes out seeds germinated successively.Subsequent use;
(3) step (2) chitting piece is cut off radicle sterilization after, transplant in clean husky bed, husky bed is gone up the insulation of plastic covering shed, is preserved moisture, with the sprouting that promotes the seed plumule and the growth of radicle;
(4) before the field, need through after " refining seedling " when transplanting behind step (3) seed sprouting, it is shifted out from husky bed be colonizated in big Tanaka again.
Wherein, step (1) is seed disinfection and Sha Zang, and the method can effectively suppress to cause growing of pathogen such as nursery stock damping off, keeps the vigor of seed germination;
Step (2) picks in time that radicle stretches out and root reaches the seed more than 3～5cm;
Step (3) cuts for the first time 1/3～1/2 of seed base-root, 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; Through cutting the measure of embryo radicle for twice; Can induce the place of the 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%, and the increase of root system area has promoted the growth of seedlings growth; Adjustment nursery stock ground and underground ratio improve the Nursery stock transplanting survival rate.The method has and uses widely and promotion prospect in the cultivating seedlings of deep-rootedness seeds.
