Abstract

A walnut tree tip removing and pruning method comprises the steps that tip removing and pruning are carried out on a central bough, main branches, lateral branches growing on the main branches and small branches bearing fruit directly; in a sapling stage, root whorled branches, opposite branches and two necking branches with too short distances on the central bough are pruned; for the annual central bough, two to three branches are reserved beside an extension head, and the rest of branches are all retracted, changed in direction or removed; the amount of buds reserved on the main branches is two thirds that of the central bough, the amount of the buds reserved on the lateral branches is two thirds that of the main branches, the amount of the buds reserved on the small branches is two thirds that of the lateral branches, and the distance between each main branch and the tip of the corresponding main branch of the same layer is larger than 1.5 meters. Cutting back is carried out on the extension head every year. The proportion of the central bough, the main branches, the lateral branches growing on the main branches and the small branches bearing the fruit directly is 1:3:13:50. According to the walnut tree tip removing and pruning method, a tree crown can be expanded in an accelerating mode, the amount of the branches can be increased, high yield in an early stage can be achieved, and a tree body structure enabling luminous energy to be used reasonably, bearing high yield and enabling the fruit with good quality to be obtained can be cultivated.

Description

The clear tip trimming method of a kind of walnut

Technical field

The present invention relates to planting fruit trees management domain, relate in particular to the clear tip trimming method of walnut.

Background technology

Peach is rose family deciduous tree, and bark black is common fruit tree and ornamencal flower and tree.Peach is happiness photosensitiveness plant, and rudiment power is with to become principal stresses strong.The bud of peach has prematurity, so, vegetative period the long and suitable area of environmental condition, can 3～4 sublateral shoots of pumping in 1 year, even more, and the situation that forms repeatedly branch and repeatedly grow.This to accelerate to be shaped and ahead of time result advantage is provided, thereby provide condition for pruning.

Walnut trimming method: cutting back refers to and cuts off 1 year vimineous part.The season of growth is extractd the young sprout top tender part of children, is called pinching, also referred to as growth season cutting back.On walnut treelet, the method for conventional cutting back developmental branch increases branch amount.Cutting back to as if from firsts and seconds side shoot the eugonic developmental branch of pumping, cutting and cutting length is 1/4-1/2, generally can sprout the branch that 3 left and right are grown after cutting back.

Sparse branching is that branch is removed and is sparse branching from base portion.Sparse branching object is generally male flower branch, sick branch, withered branch, useless water sprout, overstocked intersection branch and overlapping branch etc.Male flower branch is too much, time to consume a large amount of nutrition, thereby it is weak to cause setting body, when pruning, should suitably remove, to save nutrition, strengthen tree vigo(u)r.Walnut branch medulla is larger, tissue looseness, the easily burnt tip of deadwood.Withered branch, except itself is without productive value, also can become the place that disease worm grows, and should wipe out in time.In the time that the inner branch density of tree crown is excessive, be in line with staying strong principle to remove at any time overstocked branch a little less than going, in order to ventilation and penetrating light.When sparse branching, should be close to branch and wipe out, can't stay short wooden stake, be beneficial to clip healing.

Slow putting do not cut, and cries again long putting, and its effect is to relax shoot growth gesture, increases short-and-medium quantity, is conducive to the accumulation of nutriment, promotes young-abounding tree result.Put (can even up rear slow putting) except the straight prosperous branch of back should not delay, all the other branches delay puts effect all.Branch length more sturdy and horizontal stretching is put, and the sprig that growing way is approximate is all easily sprouted in front and back.Not cutting back of weak branch, one section of next year growth, very easily forms bud.

Perennial secateurs is cut and recalls contracting or claim contracting to cut, and this is a kind of the most frequently used method during walnut is pruned.The effect of retraction because of the position of retraction different different.The one, rejuvenation effect, the 2nd, inhibitory action.In production, the utilization of rejuvenation effect has two aspects, and the one, local rejuvenation, for example retraction upgrades fruit-bearing shoot cluster, the perennial tediously long sagging slow branch etc. of putting.The 2nd, entirely set rejuvenation, be mainly that old and feeble tree retraction upgrades.In production, use the prosperous strong auxiliary support branch of inhibitory action major control, the strong skeleton branch in inhibition tree vigo(u)r imbalance etc.

Summary of the invention

The object of this invention is to provide the clear tip trimming method of a kind of walnut that can improve walnut output.

In order to realize foregoing invention object.The clear tip trimming method of walnut, comprises that center is dry, major branch, main cladogenous side shoot, and the clear tip of the sprig of direct result is pruned; On treelet Qi Jiang center is dry verticillate with branch, the card neck secateurs of life, two hypotelorisms is removed; Annual center is dry, stays 2 ~ 3 except extending head, and remaining all bounces back, turns to or combs and remove; Major branch stays dry 2/3 of the twig amount of staying centered by twig amount, side shoot stay twig amount be major branch stay twig amount 2/3, sprig stay twig amount be side shoot stay twig amount 2/3, with the distance of interlayer major branch and the major branch tip of a branch more than 1.5 meters.

Described extending head often carries out cutting back every year.Described center is dry, major branch, main cladogenous side shoot, and the ratio of the sprig of direct result is 1:3:13:50.

The clear tip trimming method of walnut of the present invention, can accelerate spreading crown, increases branch amount, early high-yield, and cultivate the tree body structure that can rationally utilize luminous energy, burden higher yield and obtain fine quality fruit.

Embodiment

The clear tip trimming method of walnut, comprises that center is dry, major branch, main cladogenous side shoot, and the clear tip of the sprig of direct result is pruned; On treelet Qi Jiang center is dry verticillate with branch, the card neck secateurs of life, two hypotelorisms is removed; Annual center is dry, stays 2 ~ 3 except extending head, and remaining all bounces back, turns to or combs and remove; Major branch stays dry 2/3 of the twig amount of staying centered by twig amount, side shoot stay twig amount be major branch stay twig amount 2/3, sprig stay twig amount be side shoot stay twig amount 2/3, with the distance of interlayer major branch and the major branch tip of a branch more than 1.5 meters.Extending head often carries out cutting back every year.Center is dry, major branch, main cladogenous side shoot, and the ratio of the sprig of direct result is 1:3:13:50.The clear tip trimming method of walnut of the present invention, can accelerate spreading crown, increases branch amount, early high-yield, and cultivate the tree body structure that can rationally utilize luminous energy, burden higher yield and obtain fine quality fruit.

In 2007-2011 years in Lvliang City, Shanxi Province with one voice Hetaoyuan carry out clearly the tip and prune and do not make to prune tree-like comparative trial.Kind is Shanxi dragon, seeding row spacing 4*5 rice, every mu of 33 strain tree vigo(u)r stalwartnesses.Under geographical conditions approach situation, adopt 5 years walnut output of this clear tip trimming method as follows with 5 years walnut yield comparisons not doing to prune:

Tree-like	High quality fruit rate/%	Fruit mass/g	Strain product/kg	Per mu yield/kg
					Umbrella shape	74.30%	18.56	10.35	341.55
Do not prune	62.40%	16.33	9.45	311.85
