Abstract
The invention discloses a cutting seedling growing method for stems below top shoots of stevia rebaudiana. According to the method, branches remaining after shearing and cutting of the top shoots are sheared into single-section stems, the stems are grouped from top to bottom, concentrated cutting and management are performed on each stem group, and coverings are gradually removed after the stem groups root successively. By means of the grouped cutting and management method, neat rooting and sprouting are achieved, unified management is facilitated, and neat, complete and robust seedlings are easily obtained.
Description
Technical field
a cuttage and seedling culture method for the following stem section of the stevia top tip, relates to the cuttage raise seedling technique of stevia, is in particular a kind ofly to cut and insert stevia branch pushing up the tip method that remaining part carries out cuttage and seedling culture.
Background technology
in the cuttage and seedling culture practice of stevia, find the stem segment cuttage nursery branch of stevia being cut into single-unit, the distance of the distance top tip is different, and the ability that survives of taking root is also different.With top the tip compared with, from top the tip more away from stem section, transplanting seedling time is longer, and taking root, it is slower to go back seedling.So often only utilize the top tip stevia carries out stevia cottage propagation on producing time, the part below the tip of top is all given it up.
in fact, each joint below the tip of stevia top, all contains axillalry bud in axil, as long as give suitable condition, can both germination and growth, and grow sprouting.But the cuttage of the top tip following stem section utilizes also does not have suitable technical support at present.The cuttage of this part is utilized and also there is certain difficulty.
Summary of the invention
the object of the invention is on cuttage and seedling culture, be difficult to for the stevia top following branch of the tip make full use of problem, a kind of method of the stevia top following stem segment of the tip being carried out to grouping cuttage and seedling culture is proposed, to improve the survival rate of stevia cuttage, and chrysanthemum seedling is grown vigorously.
the present invention is achieved in that
a cuttage and seedling culture method for the following stem section of the stevia top tip, draw together following steps:
(1) draw materials: from the stevia branch that clip long 30-40cm in field is long;
(2) pushing up the tip cuts slotting: cut the top tip from the top 3-5cm of branch and concentrate cuttage and seedling culture;
(3) section of cutting: the top tip is cut and inserts the stem section that remaining branch is cut into single-unit;
(4) divide into groups: by above-mentioned stem section according to order be from the top down divided into second section, Section three, Section four ... each group;
(5) cuttage: each group of stem section concentrated cuttage respectively on different seedbeds;
(6) cover: on seedbed, build small arched shed, and covered with plastic film and sunshade net, carry out nursery maintenance;
(7) take off lid: each group mutually continuous take root after progressively throw off covering respectively.
beneficial effect of the present invention:
be in the stem section of branch different parts, the time of growth is different, and the maturity of tissue development is different, and physiological active degree is also different.On a branch, the root of hair viability of the top tip is the strongest, and near the tissue of the top tip, its growth time is shorter, and the maturity of tissue development is lower, and physiologically active is stronger, takes root faster after cuttage.Otherwise away from the tissue of the top tip, its growth time is longer, and the Developmental maturity of tissue is higher, and organization is further aging, and physiologically active is more weak, takes root also slower.So to the branch below the tip of top, according to order from the top down, be cut into the stem section of single-unit, take cuttage in set of packets, the stem section that the way managed respectively is conducive to Different node is taken root long seedling, grows vigorously.The stem section of the nearly tip is taken root early fast, survives early, early takes off lid; The stem section of the tip far away is taken root slowly, and survive late, evening takes off lid.Do like this and can make Different node, the stem section of different regeneration capacity all obtains sufficient growth conditions, and root of hair is seedling also, survival and growth, and the stem section of different parts is all fully utilized.Meanwhile, each joint below the tip of top is through cuttage, and the stem section of single-unit has 2 axillalry buds, can send two sproutings, grows up to two branches, if for cuttage, can obtain higher reproductive efficiency than the top tip.
concrete implementation example:
the cuttage of stevia strain-9:
(1) draw materials: from the stevia branch that clip long 30-40cm in field is long;
(2) pushing up the tip cuts slotting: cut the top tip from the top 3-5cm of branch and concentrate cuttage and seedling culture;
(3) section of cutting: the top tip is cut and inserts the stem section that remaining branch is cut into single-unit;
(4) divide into groups: by above-mentioned stem section according to order be from the top down divided into second section, Section three, Section four ... each group;
(5) cuttage: each group of stem section concentrated cuttage respectively on different seedbeds;
(6) cover: on seedbed, build small arched shed, and covered with plastic film and sunshade net, carry out nursery maintenance;
(7) take off lid: each group mutually continuous take root after within the 9th day, the 11st day and the 12nd day, progressively throw off covering respectively.
this way finally respectively forms motility rate and all reaches 100%, identical with the survival rate of top tip cuttage; Take root, send out seedling neatly, be bred as average 2 branches of individual plant of seedling, a branch more than top tip seedling; Individual plant stipes number 5, than many 1 of top tip seedling, has higher reproductive efficiency for cuttage than top tip seedling.
