Description

A kind of grafting green cucumber root-planting method
Technical field
The present invention relates to a kind of root-planting methods of cucumber seedling to realize the method for dividing root specifically by the grafting of cucumber seedling.
Background technique
It is found in the research to fields such as all kinds of stress (such as moisture, saline and alkaline) and Nutrient Absorptions, it is native under natural conditions Each factor (environmental factor, nutritive water equality) is all different in both horizontally and vertically distribution in earth, and this nonuniformity is to people More acurrate meticulously understand plant in depth and bring certain difficulty.Blackman and Davies (1985) is to probe into soil moisture Influence of the content to corn stomatal movement, takes the lead in designing and root-planting method is utilized.Then, root-planting method is in various crops It is widely used in the research of (such as cotton), garden crop (such as cucumber, citrus).Using dividing the method for root that can not only simulate The growth conditions of plant under field conditions (factors), and certain factor pair under the conditions of root system two sides are in identical or different can be probed into The influence of the plant growth and development keeps research easier, quick and accurate, and can Enhancement test result accuracy and persuasion Power.
Currently, the root-planting method generallyd use is directly to be divided into two parts root system or more parts.But due to root system of plant quantity It is numerous, it is difficult to accomplish to divide equally.And for system of taproot plant, it is also necessary to first cut main root before dividing root, it is original to destroy root system Structure, need specific culture apparatus carry out point offspring culture and survival rate it is low, the experimental study period is also grown, more unfavorable It is the situation for causing research material that cannot react plant normal growth development completely due to cutting main root, greatly reduces research knot The accuracy of fruit.Thus, this carrys out inconvenience for studying the system of taproot vegetational zone as cucumber.Dong Hezhong etc. (2010) is built A kind of method for dividing root for cotton has been found, has divided root research to provide new way for cotton using a kind of grafting means.But due to There are larger differences in growth and development characteristic and in the structure and composition of stem for cucumber and cotton, use its institute through test of many times The method grafting green cucumber shoot survival percent of description is undesirable.Therefore, a kind of neither destruction main root is established, and can improve and divide root cucumber The novel root-planting method of shoot survival percent is very necessary.
Summary of the invention
The technical problem to be solved by the present invention is to according to defect of the existing technology, provide one kind to be suitble to include that cucumber exists The Split-Root Nutrient Solution Method of the simple and effective of interior system of taproot plant, high-survival rate.Two sides root system is complete, consistent after this method can guarantee point root Good, the grafting root-planting shoot survival percent nearly 100% of property.
The technical scheme adopted by the invention is that:
A kind of grafting green cucumber root-planting method, using having, 2 true leaves, root system be complete, in the same size, no disease and pests harm, growth Healthy and strong cucumber seedling is as grafting, and selecting one plant of cucumber seedling, beveling forms notch, another strain from top to bottom at its hypocotyl Cucumber seedling chamfers from bottom to top in the same location of hypocotyl and obtains notch, is fixed after the docking of the two notch is chimeric with Grafting clip; The cucumber seedling for forming notch from top to bottom is stock strain, and it is scion strain that another strain, which has the cucumber seedling of notch from bottom to top, Stock true leaf and growing point are removed after grafting survival;Being divided to offspring tool, there are two complete root systems to contain two hypocotyls, and one shares Scion.
Further, the method specifically comprises the following steps:
(1) full, neat and consistent cucumber seeds, seed soaking, vernalization 1. seed treatment: the preparation of cucumber seedling: are chosen;2. selecting It takes the consistent seed that germinates to be seeded in the hole tray of the seedling medium equipped with sterilizing, after planting covers the seedling medium of one layer of sterilizing; 3. hole tray after planting is set in phjytotron, after seedling grows the 1st true leaf, appropriateness controls water and promotes root growth hair It educates, nurturing staff;After seedling grows 2 true leaves, choose that root system is complete, cucumber of in the same size, no disease and pests harm, robust growth Seedling, a part are used as scion strain, and a part is used as stock strain, and preparation starts to graft;
(2) it grafts and divides root: taking scion, be in 15~20 degree of angularly upper oblique partial applications at 1~1.5cm of its cotyledon lower part, Depth reaches plumular axis diameter about 3/5~2/3;Stock is taken, is in 15~20 degree of angular lower bevelings at 1~1.5cm of its cotyledon lower part, Depth reaches plumular axis diameter about 3/5~2/3;It is fixed after stock and the docking of the notch of scion are fitted into Grafting clip, after grafting survival Remove the true leaf and growing point of stock.
Further, 1. seed treatment in step (1): full, neat and consistent cucumber seeds are chosen, 55 DEG C are hoted water treatment of seeds 10 minutes, then stirring to room temperature is soaked seed 6 hours, and seed is put in the culture dish for being covered with the double-deck filter paper with distillation water-soaked It is interior, it is placed in 28 DEG C of insulating boxs vernalization 24 hours.
Further, 32 holes that the consistent seed that germinates is seeded in the seedling medium equipped with sterilizing are 2. chosen in step (1) Hole tray irrigates bottom water before sowing, every hole broadcasts 1, depth about 2cm, after planting covers the seedling medium of about 1cm thickness sterilizing;Wherein, Seedling medium is that 1:1 is mixed by volume for turf and vermiculite.
Further, 3. hole tray after planting to be set in phjytotron in step (1), diurnal temperature is 25 DEG C/15 DEG C, Photoperiod 14 hours/10 hours, daytime 400 μm of olm of average light intensity-2s-1;After seedling grows the 1st true leaf, appropriateness It controls water and promotes root growth and development, nurturing staff;After seedling grows 2 true leaves, choose root system it is complete, it is in the same size, without disease pest The cucumber seedling of evil, robust growth, a part are used as scion strain, and a part is used as stock strain, and preparation starts to graft.
Further, grafting carries out in greenhouse in step (2), appropriate shading, and temperature is controlled at 20~25 DEG C;Graft work Tool is sterilized with 70% medicinal alcohol.
Further, grafting is transplanted in the basin of bore 12cm high 10.5cm, is placed in artificial after grafting in step (2) In climatic chamber, seedbed and plastic covering film are irrigated, appropriate shading treatment removes plastic film and shading facility after 2~3d, transfers Connect the true leaf and growing point of rear 5~6d removal stock.
Beneficial effects of the present invention:
(1) the method for the present invention stock, scion during graft union is intact plant, and it is true to remove stock after healing Leaf and growing point ensure that the consistency of two root growths in agglutination;It is original without directly destruction or indirect asynchronous stimulation Two root systems ensure that two sides root system integrality and consistency, more accurately simulate cucumber normal growth situation.
(2) the method for the present invention is simple and easy, high-efficient;Divide root graft shoot survival percent high, nearly 100%;It is applied widely, it fits The system of taproot plant preferably grafted can be used the method and divide root.
(3) the method for the present invention can be used for carrying out the accurate subregion irrigation of the crops such as cucumber, root system stress and Nutrient Absorption experiment Deng research, there is important scientific research value;It is practical to can also be used for culture of crop High efficiency and high quality cultivation and ornamental plant etc. Production link.
