In the selection and process of cuttings, generally choose annual germinating branch, now the degree of lignification of fringe bar is low, be beneficial to calli induction, and then form young root, during cuttage, section needs to be cut into inclined-plane, because the area of draws water can be increased like this, several leaves to be with in addition, because plant will carry out
photosynthesismanufacture
organic matter, should also be noted that when fringe bar is chosen select fringe bar sturdy logical straight, leaf bud is full, blade does cuttings without the branch of damage by disease and insect.
The long 3-5 centimetre of cuttings selected in embodiment 1 also leaves at least leaf, belong to the short fringe in cuttage, short fringe is because burying more shallow in lower end, aeration condition is good, be conducive to root of hair and survive, short fringe all will leave 1-2 leaf, blade stored nutrient material, and carry out photosynthesis, very large to root of hair survival of random.
Select spring the annotinous branch of having spent natural dormancy period as cuttings, its shoot vegetative material abundance, cuttings is germinateed very fast, take root slow, the cuttage survival rate of branch be improved, before cuttage, root process can be urged to cuttings, make rudiment after the first root of hair of cuttings, or rudiment of taking root synchronously is carried out.
Select autumn the dormant branch of lignification then as cuttings, its branch development enriches, sprout is full, carbohydrate content is higher, inhibiting substances does not also produce completely, the optimum phase terminates to carry out cuttage by the previous moon in growth of not yet falling leaves, cuttings easily forms callus and not enough root, is beneficial to safe overwintering.
ABT root-inducing powder is a kind of wide spectrum, efficient, compound
plant growth regulator, be applied to cuttage and seedling culture, can hestening rooting, shorten rootage duration, improve rooting rate, the seeds cottage propagation that difficulty is taken root success, its effect is better than indolebutyric acid and naa; By seed soaking, spray seed or plant, processing block root or stem tuber etc., make various crop seed seedling that a series of physiological change occur, and improves budding gesture, germination rate, accelerate to nourish and grow, well established and vigorously developing, makes crop ontogeny healthy and strong.
What select in embodiment 1 is the cuttings process that ABT2 rooting powder solution is mainly applicable to plant cuttage propagation, particularly difficult plant cuttage nursery of taking root, to root induction, promote well developed root system, improve cuttage survival rate, when processing cuttings, quickly dipped method is adopted cuttings to be dipped in cuttage again after 30 seconds in 2000ppmABT2 rooting powder solution.(only the concentration of ABT2 rooting powder solution and cuttings soak time are made through repetition test and change, other steps are with embodiment 1), test data sees the following form, and adopts this embodiment 1 to process the survival rate of the great Hua trachelospermum jasminoide of cuttings the highest, growth cycle is the shortest, is most preferred embodiment.
Carbendazim is a kind of broad spectrum activity
bactericide, to various crop by
fungi(as imperfect fungus, many
sac fungi) cause
diseasethere is control efficiency, can be used for
blade facespraying, seed treatment and soil treatment etc., carbendazol generally adopts 40%-50% carbendazim proportioning solution.
Thiophanate methyl is also a kind of broad-spectrum germicide, has interior suction, preventive and therapeutic action, effectively can to prevent and treat various crop
disease, can be used for soil treatment, thiophanate methyl liquid generally adopts 50%-70% thiophanate methyl proportioning solution.

After cuttings cuttage, final-period management to be carried out from humidity, temperature and light according to three aspects.
Humidity aspect, cuttings dehydration, just can be wilting withered.Before a large amount of root of hair of cuttage fringe, keep the water suction of cuttage fringe to be that cuttage is successfully crucial with dehydration balance, and the excessive dehydration of cuttage fringe is the main cause of cuttage failure.If antecedent soil moisture, cuttings is withered dead soon, if but scholar's earth excess moisture, also can cause air deficiency, expiratory dyspnea, cause cuttings leaf to come off and dead, it is suitable that soil water-containing reaches 60%-70% most; The water suction of relative air humidity big leaf's slice easily, reduces leaf transpiration dehydration, reduces evaporation from land surface, keeps soil moisture, promote root of hair, therefore relative moisture is the bigger the better.
Temperature aspect, cuttings root of hair needs certain temperature, and temperature is very large to cuttage rooting, survival of random, and the height of temperature has very large relation to the activity of the respiration of cuttings, transpiration, enzyme and meristem cell division ability etc.Cuttings root of hair is accelerated along with the rising of temperature within the specific limits, and the optimum temperature of cuttings root of hair is 20-30 DEG C, the most desirable with 25 DEG C, and at this moment overground part and underground part are all more neat; General cuttings root of hair between ground temperature 20-35 DEG C, ground temperature lower than 20 DEG C or higher than 35 DEG C, unfavorable cuttings root of hair.
Illumination aspect, photosynthetic source is carried out in illumination, and when lacking sunlight, photosynthesis can not carry out smoothly, and also just can not produce the needs of enough organic nutrition supply cuttings healing and taking roots, illumination also can improve soil temperature, is beneficial to cell division.But illumination is defended too by force and temperature can be caused too high, transpiration is strengthened, and dehydration is too much, and blade is burnt, and cuttings is withered dead, and putting cuttage wants appropriateness to shade, and shading hut is advisable with 50%-70%.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
