Abstract

The invention discloses a bamboo willow mulching film covered cuttage method. A mulching film with the width of 40-80cm is selected, a one-year-old flat stubble strip with the thickness of 0.8-1.2cm is cut into a cutting slip with the length of 10-20cm, the upper end of the cutting slip is flat, the lower end of the cutting slip is in a U shape, the distance between a cutting notch and the upper portion of a terminal bud is about 1cm, the cutting slip is soaked in a water tank for 3d, water is changed per 24h, 1% thiophanate methyl is used for soaking for 24h, the line space of plants is 30cm*40cm, and when the cutting slip is perpendicularly inserted in soil, the first bud on the upper portion is exposed out of the mulching film by 1-2cm, and sufficient water is supplied.

Description

Bamboo willow covering with plastic film cottage method

Technical field

The invention belongs to plant cultivation method technical field, relate to a kind of bamboo willow covering with plastic film cottage method.

Background technology

Bamboo willow is a willow kind of preferably educating and taming out through selecting.Its form, side shoot, dense planting is similar with bamboo, is named as bamboo willow.Be several maximum Zhi Yeji seedling company joint studyes of California, USA agricultural university and the U.S., by the tremble with fear good hybridization strain of bamboo, korean willow, the seed selection of osier willow combined hybrid of the U.S..China national level R&D institution introduces from the U.S., and by the evidence success of 1～4 grade, 8 regions, the whole nation, cold-resistant, and drought resisting anti-ly the each side performance such as floods considerably beyond the domestic various quick growing species of treess at present.Bamboo willow is Salicaceae sallow.Arbor, growth potential is large, and height can reach more than 20 meters.Green, smooth during bark children.Apical dominance is obvious, and axillary bud sprouting power is strong, and branch early, spend by side shoot and trunk angle 30～45.Tree crown turriform, branch is even.Leaf lanceolar, single leaf alternate, blade reaches 1522cm, the long gradually point of wide 3.5～6.2cm tip, base portion wedge shape, there is obvious serration at edge, and face of blade is green, back side canescence, petiole is micro-red, shorter.Bamboo willow is new hybridization of willows kind, through the choosing of nearly 4 years of Saturn company, preferably educates and tames, and bamboo willow is being inherited on the basis of traditional willow kind many merits, has further improved fast-growing and the resistance of these seeds.This kind has been conducive to change the single situation of China's quick growing species of trees, promotes fast-growing and high-yield plantation to development in pluralism, brings more wide development space will to the development of China's forestry industry.

Summary of the invention

The invention provides a kind of bamboo willow covering with plastic film cottage method.

Bamboo willow covering with plastic film cottage method of the present invention adopts following proposal: selecting width is the mulch film of 40～80cm, rugosity is 1 year life stubble bar of 0.8～1.2cm, is cut into the long cuttings of 10～20cm, above holds level with both hands, the lower end shape of a hoof, clip is apart from 1cm left and right, terminal bud top, in pond, soak 3d, every 24h changes water once, with 0.1% thiophanate methyl, soaks 24h, seeding row spacing is 30cm * 40cm, cuttings is vertically inserted to soil, and top the first bud exposes the outer 1～2cm of film, waters sufficient water.

Embodiment

Below in conjunction with embodiment, bamboo willow covering with plastic film cottage method of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.

Select the coast is clear, physical features is smooth, and irrigation and drainage are convenient, the sandy loam that soil property is fertile, loose and loam.Before whole ground, apply the farmyard manure 60～80m becoming thoroughly decomposed ³/ hm ², phosphate fertilizer 250kg/hm ², diammonium phosphate 200kg/hm ².By following 3 steps, carry out farming: soil deeptillage, the degree of depth 30～35cm, fully mixes fertilizer and soil, is conducive to absorption and the growth of trees; The ground of ploughing deeply is harrowed 1 time, required to accomplish to harrow real rake thoroughly, reach flat, loose, even, broken, be conducive to like this overlay film and cuttings cuttage; After raking the soil level, to suppress, a kind of farm tools is flat, is beneficial to nursery soil moisture conservation.Selecting width is the mulch film of 40～80cm, in whole good ground, covers comprehensively, is conducive to like this soil moisture conservation and suppresses weeds propagation and widespread.Overlay film will, according to south-north direction, with the damage of windproof film over the ground, also be conducive to cuttage cuttings.Bamboo Liu Qiumo stop growing or early spring resin before flowing, gather kind of a bar, at this moment plant nutrient abundance in bar.General select 1 year life stubble bar that rugosity is 0.8～1.2cm, select that degree of lignification is high, robust growth, leaf bud are full, without damage by disease and insect and the kind bar that has no mechanical damage, after such kind bar cuttage, easily take root and survive, seedling growth is healthy and strong.Clip cuttings should be carried out in indoor or cool canopy.In 3 months, be cut into 10～20cm long cuttings by kind of bar the last ten-days period, above hold level with both hands, the lower end shape of a hoof; Requirement terminal bud is full, and clip, apart from 1cm left and right, terminal bud top, notices that otch is level and smooth, and the cuttings shearing is soaked 3d in pond, and every 24h changes water once, with 0.1% thiophanate methyl, soaks 24h; Or be embedded in husky Tibetan in hole with wet sand.Cultivation bamboo willow is with spring and autumn cuttage, and spring, during cuttage, north and south was that spacing in the rows, thing are line-spacing (30cm * 40cm) in early April.When cuttage top the first bud exposes the outer 1～2cm of film, cuttings is vertically inserted to soil, during cuttage, will first punch, prevent that mulch film is brought in cuttings, suppress taking root of cuttings; Can not insert, can not pedal sky, not interrupt, do not hinder skin, do not hinder bud.Meanwhile, jack will be treaded, and cuttings and soil are combined closely.After completing, cuttage fills with immediately sufficient water, to guarantee surviving of cuttings.Seedling raise period in autumn front and back at the beginning of 11 months, method is the same.

Cuttings after cuttage through watering, bud picking, topdress, overwinter management, weeding and prevention and elimination of disease and pests management Hou Chu garden.

Above-described embodiment does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.

Claims

1. a bamboo willow covering with plastic film cottage method, is characterized in that, comprises the following steps: selecting width is the mulch film of 40～80cm, rugosity is 1 year life stubble bar of 0.8～1.2cm, is cut into the long cuttings of 10～20cm, above holds level with both hands, the lower end shape of a hoof, clip is apart from 1cm left and right, terminal bud top, in pond, soak 3d, every 24h changes water once, with 0.1% thiophanate methyl, soaks 24h, seeding row spacing is 30cm * 40cm, cuttings is vertically inserted to soil, and top the first bud exposes the outer 1～2cm of film, waters sufficient water.
