Pinching is erased the lateral bine of intensive sprouting with facilitating lateral bine at 1.6m, it is ensured that lateral bine uniform spatial distribution, adjacent lateral bine distance
It is maintained at 30cm or so.
7. pruning
Focus on spring bud picking and summer pruning：Spring erases unnecessary bud on trunk and the parallel climing, position sprouted on lateral bine not
When or overstocked bud；If there are multiple buds in a section, 1 strong bud is only selected and remain；When the sprouting of reservation grows to 25cm, it is pinched
Point, pinches bud point when pinching point flat, but does not crumb or pinches disconnected, pinch the flat advantage without crumbing and be that the life of shoot apex can be retained
Long element makes its reflux be conducive to shoot growth（It is primarily referred to as long thick）, and traditional to pinch the heart then be to pinch disconnected or stem apex of crumbing to push up
Hold auxin to be lost in, plant stops growing up, therefore using pinch it is sharp do not crumb or pinch it is disconnected by the way of it is possible to prevente effectively from nutrition
Loss, branch is necessarily developed more sturdy than pinching disconnected mode in same time.Summer is to more new district（Core wire）
Within the branch of excessive growth that grows up trimmed by the way of retaining two bud cutting backs, the branch of excessive growth grown up other than more new district is adopted
With directly remove or zero leaf trim mode trimming, remove overstocked branch and weak branch；The intersection of adjacent two trees bearing basal shoot end is new
Slightly, it is trimmed using zero leaf trim mode.
Winter pruning：Heavy pruning is taken to weak tree, to restore tree vigo(u)r.Base portion has the branches and tendrils of apparent innovation shoot to bounce back to innovation shoot
At sprouting；Long branch is cut in the place of 0.6cm or so.It with rope or ties up branch card and is fixed to climing after the completion of winter pruning
On frame face.Ensure that branches and tendrils are tiled to be fixed on frame face, cut not formed arch branches and tendrils, otherwise the coming year vault easily expedite the emergence of out to
The branch of excessive growth of upper growth.The target of pruning be to be formed it is four dry two parallel double climing tree-like, this is tree-like be effectively reduced because
Canker infects and the risk in the gardens Si Shuhui, and after tendril is infected by canker, in the case where infecting position 20cm, quick height connects again
Rejuvenation, using the compensating action of plant, the branch not infected by canker increases fruiting amount, can effectively reduce Kiwi berry and burst
It is lost caused by ulcer disease.
Focus on spring bud picking and summer pruning energy and the earth reduces winter pruning amount, reduces trimming wound, can effectively reduce
The infection rate of Prospect on Kiwifruit Bacterial Canker reduces the generation of canker.Coordinate the copper such as sprayed with copper oxychloride after fallen leaves and winter pruning again
Preparation is handled with wound treasured, can effective prevention and control canker generation.
8. canker plant is handled
Canker is infected to scionwood item, at morbidity from graft union with a distance from far, can be cut at 20-40cm down along morbidity
Fall, then facilitates culture main stem again；Close from graft union, after being cut along the place of the downward 5cm of graft union or so again again
Grafting culture；Canker is infected to stock, stock can be cut down, then high is again connect after facilitating sprouting from base portion.
9. water and fertilizer management
Treelet（1-3 is raw）：In sapling rudiment to before there are 3 mounted blades, only waters, do not apply fertilizer.It pours within general 15 days or so
Water, rainfall is plentiful does not water.After having 3 mounted blades, foliage-spray dilute 400-500 times urea ammonium nitrate solution or
0.5% urea, every 20 days or so primary, after preferably in the afternoon 5 points or cloudy every 2-3 times additional 0.3% potassium dihydrogen phosphate
It carries out.Autumn（The 9-10 months）Every plant of organic fertilizer 25-30kg and balance composite fertilizer 100-150g and appropriate trace element fertilizer.
At age tree（Life in 4 years and after）：Annual fertilising 5 times.It is rudiment fertilizer for the first time, is applied before spring bud.Spring soil
Earth thaws, after sap flowing, and tree body comes into play, and the advantageous rudiment of fertilising of this phase is bloomed, and is enhanced the vigor of new root, is promoted root
Absorption to nutriment promotes young sprout growth.Rudiment fertilizer is preferably applied before germination, based on instant nitrogenousfertilizer, be equipped with a small amount of phosphorus,
Potash fertilizer.Second is Hua Qianfei, is applied within 10-20 days before flowering, main to apply the micronutrients such as phosphorus potash fertilizer and boron calcium, is improved
Percentage of fertile fruit prevents shedding.Third time is fruit-promoting fertilizer, thank spend after application in 30-50 days, this stage fruit starts to expand rapidly, root
It is that expansion rate is fast, Shoot growth is vigorous, needs a large amount of nutrient, and at this moment applying fertilizer is to shape fruit, the rush tip, expansion tree crown
Important period, the bearing basal shoot formed to current year raising yield and the coming year have great relationship.At this time will long fruit, also to carry
High fruit quality should apply the complete fertilizer that nitrogen, phosphorus, potassium add micronutrient, can significantly improve fruit quality.4th time is quality
Fertilizer, thank spend after 60-90 days apply, for make fruit inside enrich, increase single fruit weight and improve quality, suitable blade face imposes 2-3
Secondary phosphorus, potash fertilizer.5th time is base manure, is applied after fruit picking to before falling leaves, based on the organic fertilizers such as compost, cake fertilizer, pigs and cattle column excrement,
