Abstract
The invention provides a bletilla striata tissue culture seedling exercising and cultivation method. The method comprises the steps that a matrix is prepared, seedling exercising is conducted in bottles, seedlings are taken out of the bottles, domestication and cultivation are conducted, and domestication management is conducted, wherein the domestication matrix is prepared by evenly mixing sandy soil or soil with sand, humus soil and sawdust. According to the bletilla striata tissue culture seedling transplantation method, every three cleaned tissue culture seedlings form a cluster, and the tissue culture seedlings are shallowly planted into a seedbed in a green onion arranging mode. By means of the cultivation method, the survival rate of the bletilla striata tissue culture seedlings transplanted to the field and the yield are increased, the transplanting survival rate of domesticated seedlings reaches over 95%, and the investment cost is lowered for a grower.
Description
Technical field
The invention belongs to traditional Chinese medicine planting technology field, be specifically related to a kind of hardening cultivation method of bletilla plantlet in vitro.
Background technology
Bletilla is that the orchid family bletilla belongs to herbaceos perennial, calls white root, Pseudobulbus Bletillae (Rhizoma Bletillae), Cold boiled chicken baby, YANGJIAOQI, purple orchid, triflorous ainsliaea leaf, company and grass etc.With stem tuber hyoscine, energy astringing to arrest bleeding, detumescence and promoting granulation; Control pulmonary tuberculosis hemoptysis, the haematemesis of bronchiectasis hemoptysis, stomach ulcer, hematuria, the disease such as to have blood in stool.The diseases such as traumatism and bleeding, burn and scald, rhagadia manus et pedis are controlled in external application.Huge commercial exploitation is had in biological medicine, health food, textile printing and dyeing, sapecial coating and daily-use chemical industry etc.Along with the demand of the exploitation of bletilla food and dyeing industry, beauty culture, bletilla consumption increases increasingly.
The seed nature germination rate of bletilla is extremely low, breeding difficulty, and wild resource is rare, and because demand is large, wild resource faces exhaustion frequently, now lists " endangered animal and plant kind international trade pact " in and is protected, therefore only take artificial breeding.Current conventional method is main mainly with plant division greatly, and to be cut into small pieces plantation by stem tuber, reproduction coefficient is low, cannot meet market demand.People start artificial propagation, and many places have employed tissue culture propagation method to obtain a large amount of seedling fast; Because tissue culture propagation carries out in artificial environment, its self-support capacity is very poor, particularly the absorption function of its coring, cane dredge transportation function, the photosynthesis function of blade can not gather and so adapt to extraneous environment, its due function can't be played completely, cause transplanting survival rate very low like this, therefore need to carry out domestication could transplant smoothly, to improve its survival rate.
Summary of the invention
For solving above-mentioned prior art Problems existing, the present invention proposes a kind of hardening cultivation method of bletilla plantlet in vitro, and this cultivation method improves bletilla plantlet in vitro to the survival rate in land for growing field crops and output, reduces the cost of investment at plantation family.
Technical scheme of the present invention is achieved in that
A hardening cultivation method for bletilla plantlet in vitro, comprise substrate preparation, in-bottle seeding, bottle outlet, domesticating and cultivating and domestication management, concrete steps are as follows:
(1) substrate preparation: by sandy soil or folder sandy soil, humus soil and wood sawdust according to weight ratio 3:2:1 mix make plantlet in vitro domestication matrix for subsequent use;
(2) in-bottle seeding: bletilla plantlet in vitro to be cultivated is moved in booth together with seedling bottle and carries out hardening, place 10-15 days under indoor natural light, then bottle cap is opened, place 1 day;
(3) bottle outlet: have the tweezers of cotton to take out plantlet in vitro by head bundle and the medium of its root is cleaned, making plantlet in vitro be divided into individual plant as far as possible; Cleaned plantlet in vitro is put into ventilating and cooling place and places a few hours, then cover the blade of plantlet in vitro with wet towel, and only root is exposed, finally root is placed in the carbendazim aqueous solution and soaks several minutes, transfer in the root-growing agent aqueous solution and soak several minutes;
(4) domesticating and cultivating: domestication matrix step (1) prepared evenly is sowed in booth, and carry out ploughing deeply soil, ditching, ridging makes seedbed; Then the plantlet in vitro step (3) cleaned transplants the seedbed to booth, and clean plantlet in vitro is one clump with 3 by transplanting method, by the mode surface planting of row green onion on seedbed, and then blinding;
(5) tame management: water weekly once permeable, topsoil only need be kept every day moistening and spray, plantlet in vitro transplants the dead seedling of cleaning after a week, transplant after 15 days, carry out single-dose application and weeding, transplant and execute foliage fertilizer once after one month, and spray an insecticide, the domestication time is 4-7 month.
Further, described sandy soil or folder sandy soil, humus soil and wood sawdust by weight proportioning be (1 ~ 3): (1 ~ 2): (1 ~ 2), preferably 3:2:1.
Further, described step bletilla plantlet in vitro (2) to be cultivated spends the hardening phase at other booths, then only need put in this booth and just can transplant for 2 days.
Further, described step plantlet in vitro root (3) soaks 2 minutes with in 1000 times of carbendazim aqueous solution, transfers in 1000 times of root-growing agent aqueous solution to soak after 3 minutes to wait for transplanting.
Further, (4) described step is evenly sprayed onto on seedbed with the carbendazim aqueous solution and the root-growing agent aqueous solution after blinding again, and waters sufficient normal root water.
Further, described step admixes bactericide and insecticide after (4) ploughing deeply soil, and is exposed to the sun 3 days.
Further, (5) described step is tamed management and is comprised temperature treatment, when noon, external temperature was too high, carries out aeration-cooling; When winter, external temperature was lower, on seedbed, Small plastic shed insulation taken by cover.
Beneficial effect of the present invention:
1, the component of plantlet in vitro domestication matrix of the present invention is made up of sandy soil or folder sandy soil, humus soil and wood sawdust, and the soil permeability of this matrix is good, is conducive to again the growth of bletilla plantlet in vitro.Clean plantlet in vitro is one clump with 3 by transplanting method, and by the mode surface planting of row green onion on seedbed, such transplanting method improves plantlet in vitro survival rate.This is because the survival rate that the survival rate of single planting kind does not have several to plant together is high, and bletilla pseudobulb form is to arrange the mode surface planting of green onion to seedbed, is more conducive to its growth than upright plantation.
2, the present invention provides an applicable transition method from test bottle to the Nature for bletilla plantlet in vitro, make that plantlet in vitro is very enough improves the absorption function of its coring, the photosynthesis function of dredging transportation function, blade of cane very soon, can reform of nature environment quickly, improve the transplanting survival rate of plantlet in vitro, application the method, can make domestication transplantation of seedlings survival rate to more than 95%.
