Abstract

The invention discloses a method for pruning a walnut tree and belongs to the technical field of fruit tree planting. The method comprises the following steps: (a) carrying out trunk fixing: carrying out trunk fixing on a young tree before leaf falling in the fall of the same year of young fruit tree fix-planting; (b) carrying out leader branch reserving: carrying out central leader branch and three first-layer leader branch reserving on the young tree in the ensuing year of young fruit tree fix-planting; carrying out second-layer leader branch reserving on the fruit tree in the third year after planting; and carrying out third-layer leader branch reserving on the fruit tree in the fourth year after planting, wherein all leader branches are reserved in a vertically-staggered manner; and (c) carrying out lateral branch reserving: reserving 3 to 5 first-layer lateral branches for each first-layer leader branch, wherein the distance from the first-layer lateral branches to base parts of the first-layer leader branch is 60 to 80 meters; reserving 2 to 3 second-layer lateral branches for each second-layer leader branch, and reserving 2 third-layer lateral branches for each third-layer leader branch; and reserving all the lateral branches in a vertically-staggered manner. According to the method, the problems that the growth speed of walnuts is low, the yield per unit area is low and the fruit quality is poor can be solved.

Description

Walnut shaping and trimming method

Technical field

The present invention relates to planting fruit trees technical field, the shaping and trimming method of especially a kind of walnut.

Background technology

Walnut is juglandaceae plant, walnut kernel is delicious, and containing abundant nutrient, trace element and a large amount of linoleic acid fat, not only can extract oil, prepare cake, candy, what people often ate also has minimizing enteron aisle to the absorption of cholesterol, the effect of preventing hypertension, arteriosclerosis and brain tonic and intelligence development, thus walnut obtains in China and plants widely; But in existing walnut plantation, walnut is left many differences, leaf is often caused to block each other, affect its photosynthesis, cause the inharmonious of fruit tree growth, thus affect the speed of walnut growth and the output of unit are, and it is low to cause walnut fruit-setting rate, the problem of fruit quality difference.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of walnut shaping and trimming method, and the method can solve the problem that walnut growth rate is slow, yield per unit area is low, fruit quality is poor.

In order to solve the problem, the technical solution adopted in the present invention is: this walnut shaping and trimming method, comprises the following steps:

A, fixed dry: before fruit seedling field planting fall foliage then, treelet to be done surely, heading height be 1 meter to 1.5 meters and the full bud of treelet lee face of selecting and remain;

B, major branch are selected and remain: carry out selecting and remain of center leader's branch and 3 ground floor major branches to treelet before the fall foliage of fruit seedling field planting Second Year; Within after planting the 3rd year, before fall foliage, selecting and remain of 2 second layer major branches is carried out to fruit tree; Within after planting the 4th year, before fall foliage, selecting and remain of 2 third layer major branches is carried out to fruit tree; Ground floor major branch, distance between second layer major branch and third layer major branch are 1.5 meters, and the plug hole that staggers up and down between each major branch is selected and remain;

Selecting and remain of c, side shoot: described ground floor major branch is selected and remain 3 to 5 ground floor side shoots respectively; Described ground floor side shoot is apart from described ground floor major branch base portion 60 meters to 80 meters; Described second layer major branch to be selected and remain 2 to 3 second layer side shoots, 2 the 3rd side shoots that described third layer major branch is selected and remain; The plug hole that staggers mutually between described side shoot is selected and remain.

Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:

1, pruning major branch of the present invention layering raw, and ventilation and penetrating light is good; Make the mobile jib of fruit tree, major branch, the combination of center branch firmly, negative cutting is measured greatly, and the life-span is long, and makes tree-like plentiful, adds setting fruit position;

2, the present invention can keep walnut robust plant, long-term growth situation is excellent, in actual plantation, survival rate has brought up to more than 90% from traditional 45%, walnut diameter year increases by more than 1.8 centimeters, branch out in year and reach 76, can bear fruit in advance compared with the walnut planted with traditional cultivating technology solid, output exceeds 25% than traditional cultivation method.
