Abstract
The invention discloses a layering seedling culturing strong rooting girdling technology method for tree varieties with difficult rooting. The method includes the following steps that step1, in the growing season, an annual growth lignified or semi-lignified new treetop is selected, a processed part is determined according to the varieties and different thicknesses, and the length of the treetop is required to be 2-15cm; step2, according to the processed part, a stem at the 1.5-13cm position above a root are subject to leaf removal, multi-line parallel equal-distance spiral cutting is performed around the stem, the cutting depth reaches a cambium, according to the varieties and different thicknesses, the cutting line distance is 0.2-1cm, the number of lines is 3-6, the number of surrounding cycles is 1.5-3, and 1-2 pieces of bark are stripped off along the cutting lines; step3, rooting agent processing and moisturizing burying are performed according to a routine technology. Compared with the prior art, the bark is spiral and continuous, an auxin high-concentration accumulation area is enlarged while the number of nutrition accumulation parts are increased, nutrition exchanging between the bark and a seed tree is guaranteed, the rooting speed of layering seedling culturing is increased, the rooting number is increased, and the layering seedling culturing of the tree varieties with difficult rooting is improved.
Description
Technical field
The present invention relates to agricultural technology field, specifically the difficulty seeds layering seedling growth brute force girdling technical method of taking root of taking root.
Background technology
Current known layering seedling growth mode mainly adopts and carves wound branch, ringing, then wound is embedded in moistening matrix, band girdle or quarter hinder blocking-up organic nutrition and growth hormone transports to trunk direction, and accumulate near band girdle mouth, impel wound to form as early as possible callus, grow new root, in order to strengthen effect, often adopt root-growing agent to process.But the seeds that take root for some difficulties, the activity site of taking root that this processing method forms is few, and the quantity of taking root is not even taken root less, and survival rate is lower; Or rootage duration is oversize, branch is easily withered.
Summary of the invention
In order to overcome the defect of existing layering seedling growth technology, the invention provides a kind of difficulty seeds layering seedling growth brute force girdling technical method of taking root of taking root.The rooting rate of having accelerated the difficult seeds layering seedling growth of taking root, has increased the quantity of taking root, and has improved take root seeds survival rate of seedling of difficulty.
The invention has the beneficial effects as follows such realization:
The first step is in the season of growth, select annual not lignification on tree body or semi-lignified newly slightly, the treatment sites of taking root is according to kind and the new different length that requires 2～15 centimetres of rugosity slightly.
Second step, in selected new slightly stem section treatment sites from the stem section of base portion up to 1.5～13 centimeters, tripping, adopt Girding cutter to make multi-thread parallel equidistant helical cut around stem section, depth of cut reaches and forms layer, according to kind with newly slightly rugosity is different, line of cut is apart from being 0.2～1 centimetre, and line number is 3～6, spiral surrounding cutting 1.5～3 weeks.
The 3rd step, according to choice of tree species, along line of cut, strip 1～2 bark, after peeling, expose 1～2 spiral xylem surface.
The 4th step, according to routine techniques, carry out root-growing agent processing and moisturizing and bury and cover.
Guaranteeing that in line-spacing situation, line number is more, more around all numbers, rootability is stronger; Along line of cut interval, strip off the skin stronger than the rootability that strips off the skin continuously along line of cut.
Compared with prior art, this difficulty seeds layering seedling growth brute force girdling technical method sensitive part of taking root of taking root of taking root has increased by 5～10 times compared with routine techniques, continuous helical form bark is guaranteeing that processing newly slightly exchanges simultaneously with elite stand nutrition, accumulation position has additional nutrients, and expand growth hormone high concentration accumulation area, the rooting rate of having accelerated the difficult seeds layering seedling growth of taking root, has increased the quantity of taking root, and has improved take root seeds survival rate of seedling of difficulty.
Accompanying drawing explanation:
Fig. 1 is stem section parallel equidistant helical cut schematic diagram of the present invention.
In figure, 1, spiral xylem surface.
Embodiment
Embodiment 1: the sweet cherry layering seedling growth brute force girdling technical method embodiment of taking root.
The first step is in the season of growth, select annual not lignification on tree body or semi-lignified newly slightly, the treatment sites of taking root requires the length of 15 centimetres.
Second step, at selected newly stem section treatment sites base portion upwards in 13 cm range slightly, tripping, adopt Girding cutter to do 4 line parallel isometric helix cuttings around stem section, depth of cut reaches and forms layer, line of cut distance is 0.5 centimetre, spiral surrounding cuts 2 weeks, along any two lines of cut, strips the bark being clipped in the middle, and exposes spiral xylem surface 1 after peeling.
The 3rd step, according to routine techniques, carry out root-growing agent processing and moisturizing and bury and cover.
Embodiment 2: the Chinese yew layering seedling growth brute force girdling technical method embodiment of taking root.
The first step is in the season of growth, select annual semi-lignified on tree body newly slightly, the treatment sites of taking root requires to be greater than 2.5 centimetre lengths.
Second step, at selected newly stem section treatment sites base portion upwards in 2 cm range slightly, extract needle, adopt Girding cutter to do 3 line parallel isometric helix cuttings around stem section, depth of cut reaches and forms layer, line of cut distance is 0.2 centimetre, spiral surrounding cuts 2 weeks, along any two lines of cut, strips 1 bark, exposes spiral xylem surface 1 after peeling.
The 3rd step, according to routine techniques, carry out root-growing agent processing and moisturizing and bury and cover.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
Claims (2)
1. the difficulty seeds layering seedling growth brute force girdling technical method of taking root of taking root, is characterized in that, step is:
