Abstract
The invention discloses a mesh rack for hybridizing stevia rebaudiana. The mesh rack is constructed in a manner as follows: three wooden sticks are vertically driven into the ground and are covered by a nylon mesh. In spring, a stevia rebaudiana parent is planted at each predetermined position of the stevia rebaudiana hybridizing mesh rack in a permanent planting manner, the mesh rack is mounted before flowering, and the stevia rebaudiana parents are covered by the nylon mesh. At a full-bloom stage, the parents are flapped and shaken from the outside of the mesh enclosure every day, so that pollen of the parents can drift in the air, and the parents are mutually pollinated and hybridized. Through hybridizing stevia rebaudiana by adopting the mesh rack disclosed by the invention, the method is simple, and the efficiency is high.
Description
Technical field
a kind of stevia is hybridized rack, relates to the crossbreeding technology of stevia, says more specifically a kind of device of mutually hybridizing for stevia two parents.
Background technology
stevia is the sugar [yielding of a kind of composite family, because flower is little, floral organ is intensive and attachment region connects fragile, adopt traditional single flower hybridization if carry out artificial hybridization, single flower bagging, complex operation, workload is large, and efficiency is low, is a larger technology barrier for carrying out in large quantity stevia crossbreeding work.It is very necessary designing a kind of device that facilitates stevia artificial hybridization.
Summary of the invention
the object of the invention is the problem existing for the existing stevia artificial hybridization in various places, propose a kind of stevia hybridization rack, in order to facilitate the artificial hybridization between stevia Parent.
the present invention is achieved in that
1. a stevia hybridization rack, it comprises support and nylon guard, it is characterized in that, and described support is made up of three waddys, and three waddy height are 1.5m, and on the ground, three hammer into a little and are triangularly arranged three vertical nails of waddys; The nylon wire enclosure is in the outside of support, and sack downwards and contact to earth.
three waddys of described formation support hammer into and are a little preferably triangular arranged, leg-of-mutton length of side 30-40cm; Described nylon guard adopts 30-60 object nylon wire to make; It is 10-15cm that three waddys of described formation support hammer into the degree of depth; Between described rack, keep the distance of 60-80cm.
a kind of using method of stevia hybridization rack
1. spring, the each strain of field planting stevia parent in stevia hybridization rack preposition, spacing in the rows 10-20cm, to each individual plant listing mark.
2. before stevia is bloomed, stevia hybridization rack is installed, Parent is covered in nylon wire.
3. after blooming, pat, shake the stevia in guard every day from the outside of guard, promotes its pollen to fly away in air, impels the mutual cross of Parent phase.
4. after seed maturity, divide receipts, point solarization, point Tibetan to the seed of reciprocal cross in guard, as the use of next year sowing.
adopt the effect of nylon guard to be the Parent of a pair of stevia and other stevia plant to keep apart, prevent insect pollination interference.
beneficial effect of the present invention:
beneficial effect of the present invention is, the stevia crossover operation technology of very complicated is simplified.In the time carrying out the artificial pollination of stevia Parent, as long as pat and rock being grown in inner stevia Parent in the outside of nylon guard, promote the flying upward of pollen, just can make the hybridization of can mutually pollinating of the flower of Parent part, the stevia filial generation of acquisition some.This operation is very simple, without technology content, not high to operating personnel's technical requirement, is easy to promote the use of.
Accompanying drawing explanation
fig. 1 is a kind of effect schematic diagram of stevia hybridization rack
in figure: 1 is support, 2 is nylon guard, and 3 is ground, and 4 is stevia.
embodiment:
below in conjunction with specific embodiment, the present invention is conducted further description.
stevia 4 is hybridized the structure of rack:
a kind of stevia 4 is hybridized rack, it comprises support 1 and nylon guard 2, it is characterized in that, described support 1 is made up of three waddys, three waddy height are 1.5m, and three waddys are vertically followed closely on ground 3, and hammering into the degree of depth is 15cm, three hammer into and are a little triangular arranged, leg-of-mutton length of side 35cm; Nylon guard 2 is enclosed within the outside of support 1, and sack downwards and contact to earth, is altered powder with protection against insect; Nylon guard 2 adopts 40 object nylon wires to make; Between rack and other rack, keep the distance of 70cm.
the use that stevia 4 is hybridized rack is for example:
determine the hybrid combination of 20 stevia 4 in spring in 2013.
1. spring, the each strain of field planting stevia 4 parents within stevia 4 is hybridized rack preposition, spacing in the rows 15cm, to each individual plant listing mark.
2. before stevia 4 is bloomed, stevia 4 is installed and hybridizes rack, 20 couples of parents are covered respectively in 20 nylon wires.
3. after blooming, pat, shake the stevia 4 in guard every day from the outside of guard, promotes its pollen to fly away in air, causes two parents mutually to hybridize.
4. after seed maturity, divide receipts, point solarization, point Tibetan to the seed of reciprocal cross in guard, as the use of sowing.Sow 40 of above-mentioned 20 combinations parts of seeds winter in greenhouse by solar heat, and each combination has all obtained the filial generation seedling of some.
Claims (5)
