Abstract

The said technology is that cuttings are placed upside down inside furrow. Owing to the reverse temp difference between the surface and the inside of soil during early spring, the bottom of cuttings is in the proper rooting environment whereas their upper part is in the dormant state. The said cuttage technology has high survival rate.

Description

Rooting-speeding technology for mulberry cuttage

The present invention is a cottage propagation ancillary technique in the production of forestry.

Mulberry Cuttage is branch to be cut into plugged ear about long 15cm in early spring according to the way of routine, the plugged ear base portion is inserted in the seedbed of putting in order equably according to certain seeding row spacing again, and keeps certain humidity in the seedbed, and its base portion normal healing is taken root.But because at the bottom of the high soil temperature of temperature in early spring, the plugged ear base portion indolence of cuttage, and the tip is taken out in the i.e. germination before its base portion healing of most plugged ear, the formation vacation is appeared vividly and is resembled, and the nutrient of the plugged ear inside that runs out very soon.Because the base portion of plugged ear is healing and taking root not as yet, can not absorb nutrient, thereby false plugged ear of living finally all will exhaust because of nutrient dead.Thereby cause survival rate extremely low, the cuttage failure.

Purpose of the present invention is to create one for the plugged ear before the cuttage can control the fringe bud and sprout and take out the tip, can promote the environmental condition of its base portion healing and taking root again, finally greatly improves cuttage survival rate.

The object of the present invention is achieved like this: early spring, abundant at sunlight, well-drained field digs a dark 0.2m, the geosyncline of wide 1.2m, bottom land is smooth osculum, per in the same way 30 a bundles of the hard stem cutting fringe of mulberry tree about the long 15cm that intercepting is good, every bundle requires base portion smooth, and then plugged ear base portion 3-5cm being immersed concentration is 100 * 10 ^-6The ABT1 rooting powder solution in soaked 12 hours, the plugged ear of handling well is concentrated, base portion is arranged up in geosyncline, requires solid matter again, surfacing, with the wet sand after the sterilization between plugged ear and the slit of bottom land is filled up, evenly cover the wet husky 2cm of sterilization again on the surface thick, sprays once permeable, take the little shed insulation of plastic film then in the above, take shading shed on the shed, do not shade at ordinary times, keep covering husky moistening getting final product.When the temperature of surface sand in the shed surpassed 30 ℃, ventilation was opened at shed two, the cooling of shading above.Like this, owing to temperature height in early spring, add the effect that heats of plastic film shed, make the surface temperature in the geosyncline remain on 20-30 ℃, and the bottom land temperature is on the low side, form the upper and lower anti-temperature difference of plugged ear, thereby realize to promote plugged ear base portion healing and taking root, can control plugged ear itself again and not sprout the purpose of taking out the tip.

Adopt such scheme, can make plugged ear is healing and taking root before advancing the land for growing field crops cuttage, and method is simple, and expense is low, the rooting rate height.

Invention further specifies to present technique below in conjunction with accompanying drawing.

Accompanying drawing is that plugged ear is urged vertical section schematic diagram during the root among the present invention.

Among the figure: 1, geosyncline, 2, plugged ear 3, wet sand 4, plastic film shed

5, soil temperature table 6, osculum 7, shading shed

In the figure illustrated embodiment, dig geosyncline (1) earlier, and reserved osculum (6), the wet sand (3) after will sterilizing then is at the thick 3cm of being no more than of geosyncline (1) bottom shop skim.After above preparation is finished, just with the plugged ear (2) handled well by falling solid matter shown in the figure in geosyncline (1), plugged ear (2) space is filled up with wet husky (3), wet husky (3) bed hedgehopping in shorter plugged ear (2) bottom, keeping plugged ear (2) base portion is surfacing, cover wet husky (3) 2～3cm of one deck then on its surface thick, soil temperature table (5) is inserted in wet husky (3) lining, top layer, water once permeable again, take the little shed of plastic film (4) then, about the high 50cm of canopy, the plastic film earth point requires closely knit compressing, and takes shading shed (7) at last on plastic film shed (4).Need every order regularly to observe temp. and humidity during the urgency, note regulating temperature between 20～30 ℃, it is wetting to keep covering sand, can reach 95% rooting rate about 30 days.

Claims

1, plant cuttage technology in the Mulberry Cuttage process, adopts plugged ear to fall to insert to bury husky method with plastic film and urges root, and it is characterized in that: the plugged ear head utilizes the plugged ear anti-temperature difference up and down to promote the plugged ear healing and taking root, the raising rooting rate downwards with husky close being embedded in the geosyncline.

2, the root technology is urged in cuttage according to claim 1, it is characterized in that: plugged ear length basically identical, after the ABT1 root-inducing powder was handled, concentrated example inserted in the specification geosyncline, covers with wet sand and buries.

3, the root technology is urged in cuttage according to claim 1, it is characterized in that: plugged ear is embedded in the geosyncline, the surface is covered flat with wet sand, ground is done the little shed of plastic film again and is heated, like this, the base portion of plugged ear is that face of land soil temperature is higher, suitable its healing and taking root, and both the trench bottom soil temperature was lower on the top of plugged ear, bud on the plugged ear is not sprouted taken out the tip.
