Abstract

The invention pertains to gardening plant propagation technological field, in particular to a fast cutting propagation method of bougainvillea spectabilis. The method comprises seedbed construction, selection and treatment of cuttings, curing management, etc.. With a thickness of 25-35mm, perlite is used as the stroma of the seedbed; the lengths of the treated cuttings are 8-12cm, the cuttings are evenly inserted into the stroma of the seedbed at a depth of 4-6cm based on certain plant and row spacing, along with scientific curing management, cotton yarns or straws are covered between the cutting seedlings for water absorption and heat preservation, new roots of the cuttings are initially formed after 14 days, and seedlings grow out after 30 days, then acclimatization and transplantation can be carried out. The invention, combined with the seedbed construction, treatment with plant growth liquid and scientific curing management technology, greatly shortens the rootage and seedling time of the cuttings with obvious rootage effect by robust taproots and high survival rate; besides, the invention is simple and easy to apply, easy and convenient to manage and has high economic benefit without occupying arable land.

Description

The cuttage and quick-propagation method of a kind of triangle plum

Technical field

The invention belongs to the propagation technique field of gardening plant, be specifically related to the asexual cuttage and quick-propagation method of a kind of triangle plum.

Background technology

Triangle plum (Bougainvillea spectabilis) belongs to Nyctaginaceae (Nyctaginaceae) bougainvillea (Bougainvillea) and belongs to, and originates in Brazil, another name bougainvillea, bougainvillea, paper flower etc.The triangle plum is the climing property of a perennial evergreen liane, warm, moistening, the sun-drenched environment of property happiness; Not water-fast wet, but impoverishment tolerant, drought-resistant.The Triangular Flos Mume look anti-to be seen, sight is strong, and it is long to have a green florescence of leaf, the characteristics that the four seasons are open, so be usually used in the lawn and intersperse plant, hedge plant and flower stand plant.In addition, the triangle plum has very strong dust suction, drug abuse function, can be used for purifying air, and afforests and beautifies environment; Cuttage is one of main propagation method of triangle plum.But it seems that from prior art ubiquity is had relatively high expectations to the cuttage branch, need the old stem of perennial living materialization semi-lignified, and the ground point selection in seedbed is also had bigger restriction, and the time is long, the not high relatively serial shortcoming of survival rate.

Summary of the invention

In order to overcome existing triangle plum cuttage technique to the restriction of seedbed, cutting and long deficiencies such as rootage duration, the present invention proposes a kind of taking root and becoming the seedling time, the triangle plum cuttage and quick-propagation method of raising survival rate of cuttage seeding of shortening.

The cuttage and quick-propagation method that the present invention proposes comprises seedbed construction, transplants a cutting and choose and handle, and science maintenance management step:

(1) seedbed construction

The cuttage seedbed should be chosen in leeward, shady and cool ground, bedside 1.0-1.5m, and length is decided as required, and high 35-40cm uses brick one-tenth all around; Selecting perlite for use is cutting medium, sprays 0.5% carbendazim solution matrix is sterilized, the thick 25-35cm of matrix, leveling;

(2) cutting is chosen and is handled

Carry out cuttage annual early March to mid-June, this moment, temperature was moderate, humidity height, convenient management.Get perennial or 1 year sturdy stem bar of life (the closely sturdy 1-2 of structure gives birth to skin, and the branch effect is best) on the sunny side, cut sth. askew into segment, must transplant a cutting, guarantee that the base portion otch of transplanting a cutting is smooth and smooth, every segment length 8-12cm, the 2-3 sheet leaf on reservation top with cutter; Soak otch 15-20min with plant growing liquid (the NAA solution of 100mg/L); Press 4-6cm * 4-6cm seeding row spacing again and will transplant a cutting the seedbed of evenly inserting pearlite interstitial substance, insert and transplant a cutting dark about 4-6cm, cover the cotton gauze or the straw of the insulation that can absorb water between the cuttage bar, compacting after watering;

(3) maintenance management

Water: will guarantee fully that matrix was moistening in preceding 10 days after the cuttage, relative air humidity is controlled at 85-95%, and every day, mist was irritated 3 times, the morning, noon and afternoon each once, each 20-30min; Mist filling every day is 2 times after 10 days, sooner or later respectively once, and each 20-30 minute; Then reduce to once a day each 20-30min after 20 days;

Illumination: then visible sparse light after 10 days progressively added intense light irradiation later on, was beneficial to blade and carried out photosynthesis in slightly shady place's maintenance in preceding 10 days after the cuttage, and the base portion that promotes to transplant a cutting produces callus and begins to take root; Can accept maintenance full sun after 25 days.Have only and fully accept sunlight, just can make new root stalwartness.

Fertile part: after the cuttage the 3rd day and the 7th day with the NAA solution of 100mg/L once to the root drip irrigation of transplanting a cutting, with the promotion rooting of cuttings.New root begins to take shape after 15 days, and can spray the potassium dihydrogen phosphate of a 2-3 about ‰ this moment weekly; Emerge and execute a urea the last week to impel the healthy and strong growth of seedling;

After 14 days, the new root of transplanting a cutting begins to take shape, and seedling forms after 30 days, and can carry out hardening, transplanting this moment.

The present invention handles in conjunction with seedbed construction, plant growing liquid and the maintenance management technology of science, and that has shortened cuttage seeding greatly takes root, becomes the seedling time, and the rooting efficiency of seedling is remarkable, main root is sturdy, survival rate is high; And have simple, simple and convenient management, economic benefit is high and characteristics such as the resource that do not occupy cultivated land.

Embodiment

Case study on implementation 1:

Select annual or perennial triangle plum branch, cut sth. askew into the cutting that 8-12cm grows even thickness, keep the 2-3 sheet leaf on cutting top with sharp pocket knife.Soak otch 20min with plant growing liquid (the NAA solution of 100mg/L), press 5cm * 5cm seeding row spacing again, insert the dark about 4-6cm of cutting, cover cotton gauze between the cuttage bar, the back compacting of watering its seedbed of evenly inserting pearlite interstitial substance.

After the cuttage preceding 10 days, every day, mist was irritated 3 times, each 25 minutes; Mist filling every day is 2 times after 10 days, sooner or later respectively once; Then reduce to once a day each 30min after 20 days.After the cuttage the 3rd day and the 7th day are with the NAA solution of 100mg/L to the root drip irrigation of transplanting a cutting once.Spray one time 2.5 ‰ potassium dihydrogen phosphate weekly from the 15th.Progressively added intense light irradiation in shade place maintenance after 10 days, and accepted maintenance full sun after 25 days in preceding 10 days after the cuttage.The result shows that cuttage seeding generally begins to take root about 14 days, rooting rate is up to 91.7%; Left and right sides seedling grew up in 30 days, can carry out hardening and the transplanting of next stage.
