Abstract
A cutting propagation method of industrial cannabis sativa belongs to the technical field of cultivation and breeding of bast fiber plants. The cutting propagation method comprises the following steps: performing final singling of seedlings of industrial cannabis sativa, wherein 1seedling is planted in one square meter; topping when the plant is 1m high and the primary branch length is 20cm, wherein the topping length is 2cm; uniformly mixing matrix and carrying out sterilization and disinfection, wherein the volume ratio of vegetable garden soil or cured loess to perlite or vermiculite to peat for planting in the matrix is 4:3:3; laying a layer of matrix which is 10cm thick on a seedbed which is 1.2m wide and 10m long; carrying out cuttage when branch shoots are 15-20cm long; preparing cutting shoots which are 10-15cm long and soaking the cutting shoots in a 1/5000 potassium permanganate solution for 20-30min, wherein only 2-3 leaves at the top of the cutting shoots which are not unfolded completely are kept, the cuttage density is 3-4cm*10-12cm and the cuttage depth is 3-5cm; setting up supports which are 50cm high, covering with a plastic film, sealing the periphery of the plastic film, performing proper shading, controlling the temperature inside the plastic film to be below 35 DEG C and the relative air humidity inside the plastic film to be higher than 85%; supplying illumination twice in morning and afternoon, 1-3 hours each time. By implementation of the cutting propagation method, 50-100 cuttage seedlings can be propagated from one seed (one seedling) after 90-120 days. The cutting propagation method is simple to operate, low in cost and high in seedling culture speed. The cutting propagation method is an optimal method for quickly obtaining seedlings with consistent genetic gene, can be widely applied to cultivation and breeding of industrial cannabis sativa and related researches.
Description
Technical field:
The present invention relates to a kind of method of industrial hemp cottage propagation, belong to crudefiber crop cultivation and breeding technical field.
Background technology:
The application of industrial hemp relates to ecological health food, auto industry, weaving, building materials, papermaking, military supplies and other light industry fields, and the recent domestic development rapidly.Industrial hemp is the dioecism cross-pollinatd plant, and in kind, interindividual variation is larger, and cultivation utilization and scientific experimentation are brought to adverse effect.The technology of the present invention is by a large amount of seedling of quickly breeding same gene type (individual plant source), and the research for different disposal on the hemp impact significantly improves reliability and the science of result of the test.
By literature search, have no the open report identical with the present invention.
Summary of the invention:
The object of the invention is to overcome the difference between existing industrial hemp kind individuality, a kind of method of industrial hemp cottage propagation is provided.
Research finds, industrial hemp after cuttings is cultivated under protective condition cottage propagation, through correct maintenance, cuttings started to take root after 10-15 days, within 25-30 days, played afterwards transplantation of seedlings or for the scientific experimentation of design.Set out by an industrial hemp seed, after 90-120 days, can obtain cuttage seeding 50-100.
Industrial hemp cuttage breeding method of the present invention, its concrete steps are as follows:
1. cuttings is cultivated the plantation of light seeding as early as possible hemp when temperature meets the hemp growth, final singling 1 strain/m
2, strengthen rich water quality management, promote numb strain growth, when numb plant height degree 1m, pinch, remove top tip 2cm, promote a minute branch growth; Remove again the top 2cm of branch when primary branch grows to 20cm, in this way on the hemp plant, obtain required minute branch.
2. matrix is prepared by removing not vegetable garden soil or the slaking loess of decomposed organic matter: perlite or vermiculite: cultivation mixes by the volume ratio of peat=4:3:3, every cube of matrix is used 200-300L soil fungicides triazolone or tmtd solution, concentration is 2 times of product description working concentration, carries out sterilizing.
3. the necessary draining in ground, preparing seedbed, seedbed is unobstructed; Seedbed width 1.2m, length≤10m; The thick matrix of upper berth, seedbed 10cm.
4. cuttings is prepared when a minute branch grows to 15-20cm length for cuttage and seedling culture; Use sharp scissors or single-edge blade to shear cuttings, length 10-15cm, retain top 2-3 the not yet blade of full extension, removes unnecessary blade and petiole, soaks 20-30 minute in 1/5000 liquor potassic permanganate; Avoid the damage to cuttings terminal bud and stem in cuttings pruning process.
5. cuttage technique cutting density 3-4cm * 10-12cm, insert dark 3-5cm; Cuttage is wanted to put in place for 1 time, plug repeatedly; After cuttage, water the liquor potassic permanganate that soaks cuttings, drenched matrix.
6. after inserting, thin bamboo strips used for weaving sheet or customization bow member are prepared in management in advance, support immediately after cuttage, and support height 50cm, cover transparent plastic film, surrounding compacting sealing, moisturizing; Use sunshade net covered with sunshade, cooling and the injury of minimizing high light radiation; Keep the interior relative air humidity of film more than 85%, temperature is no more than 35 ℃; Every day of fine day early, the period in evening throw off cover from sun make cuttings early, respectively accept sunlight 1-2 hour evening; Along with the growth of cuttings and adaptability strengthen, early, see that the time of light respectively extends to 2-3 hour evening.
7. within 10-15 days, start to take root after playing the cuttage of transplantation of seedlings hemp, continue to cultivate 10-15 days, balled transplanting or lifting are for scientific experimentation.
Through the cuttings of 90-120 days, cultivate and cuttage and seedling culture, can be by the consistent cuttage seeding 50-100 of a seed (1 seedling) breeding hereditary basis.
The invention has the advantages that:
1. can overcome the individual difference of industrial hemp seed shoots, a large amount of seedling of quickly breeding same gene type (individual plant source), the research for different disposal on the hemp impact, significantly improve reliability and the science of result of the test;
2. the method is simple to operate, and cost is low, grows seedlings fast, and growth is neat, can be widely used in industrial hemp cultivation, breeding and relevant scientific research.
