Description
Technical field
The invention belongs to trees improving technology fields, and in particular to a kind of Pinus Massoniana Lamb In Seed Orchard maternal plant spray cutting back side
Method.
Background technique
Conventional Forest Tree Genetic Breeding and breeding production in, for experimental forest and breeding garden construction after cultivating and managing,
Mainly field weeding, improvement of soil fertility, irrigation take precautions against drought, spray and control worm, supple-mentary pollination etc., but set in previous seed orchard management
Body administrative skill refers to less.
Masson pine is strong positive tree species, and growth result needs sufficient illumination, and aforementioned way to manage cannot all solve
Certainly increase lighting issues, only so that the solid elite stand of breeding garden is reached purpose that is ventilative and increasing illumination by pruning.
With shaping technique, since immature elite stand, tree body is presented in the spatial development for making limb skeleton structure open a business towards evacuation
Receive the tree crown that illumination is sufficient, solid face is big out；By trimming measure, interior thorax is cleared up, the branch of thin and delicate non-robustness is pruned off, makes
Tree body ventilation and penetrating light, with sharp Growth status and solid.
Applicant has found in long-term research process, implements tree body management to Pinus Massoniana Lamb In Seed Orchard, there is to be solved three
A critical issue: first is that downgrading tree body, the various technical measures with Dwarf Effect of integrated use place restrictions on Tree height growth, at
The elite stand height control that year largely blossoms and bears fruit implements tree body management and is intended to management easy to produce and cone picking in 6m or so；
Second is that culture is tree-like, grow according to the habit of masson pine tree body limb and naturally it is various tree-like, it is expected that culture is main
It is tree-like, it can be summarized as cup-shaped the first transaction of a day's business shape, evacuation globular model, three kinds of ovate cone, so that breeding garden elite stand cultivates tree-like reference
Using；Third is that updating fruitful branch, in order to delay tree crown to extend and update fruitful branch, mode is cut using retraction, by current growth
Side shoot leading shoot stay stake to bounce back.It stays stake retraction mainly to place restrictions on tree crown extension to young sprout retraction, while staying the branch stake of certain length
Promote it and sprouts the new fruitful branch of culture.Having been proven in practice that in recent years: young sprout retraction stays stake rush sprout, cultivate new fruitful branch, skill
Feasible in art, effect is affirmative.
Summary of the invention
In view of the problems of the existing technology, it is an object of the invention to design, to provide a kind of Pinus Massoniana Lamb In Seed Orchard maternal plant tender
The technical solution of branch cutting back method.
A kind of Pinus Massoniana Lamb In Seed Orchard maternal plant spray cutting back method, it is characterised in that in annual 4~May of spring
Between, current year raw young sprout is when 50~60cm, branch new life green needles 1~2cm of length, more than leading shoot base portion at 10~20cm
Stake is stayed in cutting.
A kind of Pinus Massoniana Lamb In Seed Orchard maternal plant spray cutting back method, it is characterised in that the current year raw young sprout
For the tender tip of 5~7 not yet complete lignifyings of wheel newly formed for the year comprising a leading shoot and several side tips.
A kind of Pinus Massoniana Lamb In Seed Orchard maternal plant spray cutting back method, it is characterised in that selection grows normal needle
Leading shoot trimmed, and guarantee to have at 5~10cm of leading shoot clip the normal needle of growth.
A kind of above-mentioned Pinus Massoniana Lamb In Seed Orchard maternal plant spray cutting back method, design rationally, through the invention can be real
Existing masson pine following functions:
(1) tree body extension is placed restrictions on: by the way that masson pine maternal plant tender lateral branch leading shoot cutting back, the part that leading shoot is cut exactly is limited
The increment (1/3 meter of suitable amount of recovery) that leading shoot edge side shoot increases extension is deducted in the only part of Seedling height and tree crown extension,
The practical amount of recovery of tree height and hat width is up to 30cm, 1 year retraction 30cm, 10 years accumulative 3m.It can be seen that cutting back technology,
It is fairly obvious that the effect grown tall and extended with tree crown is placed restrictions on for breeding garden elite stand, is one of the effective measures that tree body is downgraded.
(2) promote side shoot solid: the solid elite stand side shoot of breeding garden forms the new branch of a wheel, intermediate 1 major branch tip, branch every year
Base forms 5~7 side shoot tips along side.Branch is all the fruit branch bred of blooming, intermediate due to the apex advantageous effect of arboreal growth
The major branch tip obtain nutrient abundance from tree body, thus Shoot growth is sturdy, it is also more to blossom and bear fruit；What other side shoot tips obtained supports
Divide with regard to few, Shoot growth is thin and delicate, the fruit of knot is also smaller.The major branch tip is cut, the superiority condition of growth, trunk infusion are lost
Readjust, make nutrient concentration flow to the side shoot tip, promote its growth with it is solid.Its effect is mainly reflected in side shoot tip percentage of fertile fruit and mentions
High, cone increase, full seed.
(3) cultivate new fruitful branch: branch retains the branch stake of 10~20cm long of base portion, needle by clip after cutting
Bud can expand sprouting, cut for 4~May, and current year, germination rate was up to 80% or more.Bud tip well-grown, each cuts branch after sprouting
The tip averagely sprouts 3 or more the new bud tips, long average 8.2cm of young sprout or so, longest young sprout 15cm, and young sprout is slightly 0.25~
0.50cm.In addition, branch cuts the bud tip shoot of rear current year sprouting, next year terminal bud germination, which is grown, can simultaneously yield positive results.Thus it demonstrate,proves
Real, the branch technology of cutting can cultivate new fruitful branch.
Specific embodiment
Further illustrate the present invention with reference to embodiments.
A kind of embodiment 1: Pinus Massoniana Lamb In Seed Orchard maternal plant spray cutting back method
Between annual 4~May of spring, the tender tip for 5~7 not yet complete lignifyings of wheel that selection current year is newly formed comprising one
A leading shoot and several side tips, current year raw young sprout is when 50~60cm, branch new life green needles 1~2cm of length, in leading shoot base portion
It is cut above 10~20cm and stays stake, and guarantee there is the normal needle of growth at 5~10cm of leading shoot clip, retraction must not cut
Mouth is located at the branch section of not needle, this is blight wood position, and blight wood will not sprout new buds.1 can be divided into the wheel new branch of branch
Leading shoot and several side tips, leading shoot downgrade tree crown for bouncing back, and the side tip gives over to fruitful branch.
Test example
One, the embodiment that branch is cut
(1) explore and optimum cut the time: in 4~June of spring, exactly current year new branch growth period, by every 10 days into
Row is once cut, 7 times total in April 11,21 days, 30 days, May 12,21 days, June 1,16 days respectively.It is explored and is obtained with this
: which is cut the moon most appropriate 3 middle of the month with, which section time to be again most in three periods of the upper, middle and lower ten days moon
It is good.
(2) it tests most suitable cut and stays pile length: cutting to preset and stay pile length, respectively 10cm, 15cm, 20cm tri-
Kind, it is required to the needle with normal length.It being selected to cut the branch of test, base portion does not have needle part to be known as " blight wood ",
There is no needle bud not have sprouting performance, within the branch stake that tool needle cannot be can be regarded as.But " blight wood " really cuts branch stake
A part, as branch pile length include " blight wood " if it should be explained that.But the clip needle bud of stake is stayed to determine to three kinds after cutting
When be observed, record the sprout time of needle bud, sprout quantity, sprout branch and thick etc., stay pile length than three kinds on this basis
Difference, determine and most suitable stay pile length.
Cut whether to succeed to be mainly reflected in and stay in stake branch section, stay a secateurs lancet leaf bud germination it is strong, at branch rate
Height, growth are sturdy, illustrate that cutting success obtains good effect.It cuts the part that branch is cut up and about stays stake branch section 2~3
Times, effect is the extension effects measured the size of amount of recovery and place restrictions on tree height and hat width, these will be by cutting branch
Length and be cut up between part mutual ratios to be illustrated.
Two, the result of implementation that branch is cut
It bounces back the specific implementation situation cut in order to illustrate branch, now to cutting the segmentation disposition of the major branch tip, clip needle bud
Germination, the increment for sprouting branch etc. are explained with expression form subitem, and see Table 1 for details.
1 masson pine branch of table cuts disposition and result of implementation
According to the result of implementation that table 1 is shown, it can affirm that branch is cut in the management of Pinus Massoniana Lamb In Seed Orchard tree body, promoted on the whole
It is of practical meaning for blossoming and bearing fruit, cultivating new fruitful branch.
(1) it is cut using current year new branch implementation: cutting test and amount to 639 new branch, it is the long 50~60cm of general branch, flat
Equal 58.5cm cuts 35~45cm of length, average 43.5cm, cuts the long 10~20cm of tool needle branch stake, average 15cm, cuts
Thick 0.7~the 0.9cm of clip of branch stake, average 0.86cm.
(2) stay a germination for clip needle bud: 639 branch stakes are cut in test altogether, wherein there is 522 stake is stayed to sprout bud
Branch illustrates that the masson pine current year needle clip bud of new branch has stronger sprouting by population mean germination rate up to 81.7%
Power.And show from early April to mid-June, germination rate is in be gradually reduced trend.
(3) needle bud can form normal branch: cutting by 639 branch of statistics of participating in the experiment and stake is stayed to sprout based at branch number
It calculates, it is average that a clip is each stayed to have 3 rudiment branch.It was grown through 4~6 months, early November investigation display: rudiment Shoot growth
Amount, average long 5.8cm, stem thickness 0.25cm, wherein good reaches 8.2cm, 0.33cm respectively, part single plant is up to 10~15cm, long
Gesture is good.
Three, branch cuts practical analysis of related results
(1) what season optimum, that month in suitable season the suitable time that branch is cut: are distinguished from annual Growing season
It is again more preferable with which in three ten days preferably in month to be best phase in ten days.Now according to existing practice and research, difference season, the moon, ten days
Differentiated and is analyzed.Test result is now distinguished into three kinds of period lists, see Table 2 for details.
1. comparing by between 4,5,6 three month: the branch stake germination rate of population average, branch stake sprout a number, sprout length,
Sprout 4 test results of a rugosity to show: 3 testing means in April are respectively 93.8 %, 3.4,9.0cm, 0.38cm；5
2 average values in month are respectively 84.4%, 3.0,5.8cm, 0.24cm；2 average values in June are respectively 60%, 2.5
A, 2.5cm, 0.14cm.Illustrate be cut within three months 4~June, but excellent, May is that good, June is poor to be April.
2. comparing by between monthly three ten days: now being cut with 5 times of progress in 4, May as a result, therefrom choosing and cut branch every time
The more clonal test data of number, carries out the comparison between ten days.According to branch stake germination rate, branch stake sprouting number in table 2, to sprout branch long
A rugosity 4 every mean of dekan numbers are spent, sprout to compare and analyze.Early April is followed successively by 100%, 2.7,5.9cm, 0.33cm；
Mid-April is 98.1%, 4.0,9.9cm, 0.43cm；Late April is 95.6%, 5.5,12.5cm, 0.39cm；4 monthly average
Value is followed successively by 97.9%, 4.1,9.4cm, 0.38cm.The first tenday period of a month in May are followed successively by 94.4%, 3.5,8.1cm, 0.30cm；In 5 months
Ten days is 92.6%, 3.0,6.6cm, 0.29cm；5 monthly average values are followed successively by 93.5%, 3.3,7.4cm, 0.29cm.By 5 ten days
Phase compares, and branch stake germination rate is reduced by ten days later with early April highest, 5 percentage values are respectively 100%, 98.1%, 95.6%,
94.4%,92.6%.Branch stake sprouts a number and increment in 4 months, preferably the last ten-days period, go up in early April and May, the middle ten days it is poor.See Table 2 for details.
2 Pinus Massoniana Lamb In Seed Orchard branch of table cuts the time and pile length is stayed to test
(2) what branch was cut is suitable for staying pile length: 2 test data of table shows that 5 clone compound averages of 5 batches are right
Staying branch stake germination rate caused by pile length in 10,15, tri- kinds of 20cm, sprout quantity, sprout length, sprout a rugosity effect is one
It causes, the measured value that 10cm stakes sprout character for 4 kinds respectively is 92%, 3.7,7.2cm, 0.32cm；15cm stake difference
For 96%, 4.0,8.1cm, 0.35；20cm stakes are respectively 100%, 5.4,10.5cm, 0.38cm.Branch 4 sprouting characters of stake
Measured value is lower with 10cm stakes, and 15cm stakes are placed in the middle, 20cm stake highests.Highest is compared with minimum, 20cm stake ratio 10cm
The germination rate of branch stake is high 8%, sprouts that a number is 1.7 more, sprouts branch grow tall 3.3cm, sprout branch slightly high 0.06cm.This illustrates that branch is cut and stays
Pile length is best with 20cm.Main cause is that 20cm stakes are more sturdy, is counted by 225 (each 75 of the 3 kinds of branch stakes) participated in the experiment:
It is slightly 0.35cm, long 20cm stake is slightly 0.38cm that long 10cm stake, which is slightly 0.32cm, long 15cm stake,.Branch stake is long and bodkin
Full of leaves close, photosynthesis savings nutrient is more, the germination and growth of advantageous branch stake.From current test analysis, the branch stake of three kinds of length is equal
It is available, but have their own advantages and deficiency.The shorter relatively good choosing of 10cm pile lengths, amount of recovery is big, favorably places restrictions on tree height and coronary dilatation,
But it is sprouted character and is slightly poorer than long shoot stake.20cm is compared with 10cm, and branch stake is 1 times long, and the superiority and inferiority of the two is exactly the opposite, long shoot stake
Germination and cut effect and be an advantage over brachyplast certainly.15cm germination and cuts effect between the stake of long brachyplast, with
It is also affirmative that 20cm stakes, which compare, is that branch cuts the selection for staying pile length suitable.
