Description

A kind of guava cuttage and seedling culture method

Technical field

The invention belongs to plant cuttage nursery field, particularly a kind of guava cuttage and seedling culture method.

Background technology

Psidium belongs to evergreen dungarunga in Myrtaceae, high 2-5m.Originate in american torrid zone, about 16 ~ the 17th century imports China into, and show the ground such as the Taiwan of south China, Guangdong, Guangxi and Fujian has cultivation more, wherein common with the eastern Guangdong in Taiwan and Guangxi.Ripe fruit band is faint yellow, and meat is thick, succulence, and how young, gas is fragrant, and taste is sweet.

Guava happiness light, likes warm, does not resist cold, like fertile, well-drained soil; Guava can with growing directly from seeds, bending pruning (air layering) and grafting nursery, because root system root turion can occur, also can use offshoot.Guava well developed root system, barren-resistant, planting survival rate is extra-high, and growth rate is express, the guava seedling sowed then is the highest grow to more than 2 meters high.Second Year of planting can grow tall 3-4 rice, and tree-walk increases thick simultaneously, and hat width expands.

Guava conventional seedbed system method is graft seedling growth, but the grafting method cycle is long, and efficiency is low, and after result, fruit has definite variability.Prior art also has and adopts the method for cuttage and seedling culture, comprises cuttage and epicormic branch cuttage, due to cuttings more options more than the 2 years branches of cuttage, and now cuttings lignification completely, cuttage root-taking effect is poor, and survival rate is lower; And the cuttings of epicormic branch cuttage selects semi-lignified branch usually, take root more easy, survival rate is higher.

Summary of the invention

The object of the invention is to: for above-mentioned Problems existing, the invention provides a kind of guava cuttage and seedling culture method, this cottage method step simply, conveniently manages, the cycle is short, survival rate is high, can cultivate a large amount of seedling at short notice.

Technical scheme of the present invention is: a kind of guava cuttage and seedling culture method, comprises the following steps:

A, cuttings are selected: require selection one, biennial in, the stalwartness on top, semi-lignified and without the branch of damage by disease and insect, branch encloses stem 1.2-1.5cm, every segment length 15cm, base portion is whittled into level and smooth prismatic, cut off by its blade, top retains three pairs of blades, and sheet leaf cuts off 1/2;

B, cuttings process: by cuttings inferior end notch with compound root-growing agent process 3-5 second, root-growing agent adopts by several plants growth hormone and synergist thereof, and formulated according to a certain percentage, the concentration of root-growing agent controls at 0.2%-1%;

C, seedbed preparation: medium of seedling bed finishing paved, extrude groove along seedbed length direction, use along groove direction and the club of the equal thickness of cuttings equidistantly inserts out aperture, hole depth 3-5cm;

D, cuttage: the cuttings in step B inserted in aperture, the cuttage degree of depth is about 3-5cm, rinses cuttings with water, irrigates cuttings surrounding substrate simultaneously, drips root-growing agent 3-5ml around cuttings;

E, cuttage post processing: before cuttage rooting, start automatic spraying system, every 10-15 minute water spray once, humidity remains on more than 85%, starts wet curtain cooling system, makes warm indoor temperature remain between 25-30 DEG C, daytime starts blower fan, keeps room ventilation, passes through shading system, regulate indoor illumination, will avoid direct sunlight before cuttage rooting, illuminance controls between 5000-10000 strangles, after cuttage rooting, reduce injection flow rate gradually, increase illuminance;

F, the extermination of disease and insect pest: every 5-7 days sprays carbendazim, tpn or zineb once;

G, move bed: cuttage seeding insert after about 15 ~ 20 days, shift out greenhouse, be placed on slow seedling 15-20 days in shading shed, extract out after sprouting, shift out in outdoor bed until cutting, the first Zhou Yingjia shades facility, is diligent in irrigating, when nursery stock grows tall to more than 50cm, can goes out garden.

H, move bed after extract sprouting out and to take root seedling strain, every strain can put slow-release fertilizer 5-6 grain, New shoot growth to a certain extent after can suitably impose thin liquid fertilizer 3-5 times.

Beneficial effect of the present invention is: a kind of guava cuttage and seedling culture method of the present invention, step simply, conveniently manages, the cycle is short, survival rate is high, can cultivate a large amount of seedling at short notice.
