Abstract

The invention discloses a method for planting early bearing walnut in autumn. The method comprises the following steps of: (1) digging a planting pit; (2) selecting a nursery stock for planting; (3) determining the density of planting; (4) trimming and treating a root system; (5) planting; (6) covering a mulching film; (7) performing nutrient and water management; and (8) performing winter protection. According to the method, the excellent nursery stock is selected, the root system of the nursery stock is scientifically treated, and a reasonable planting method and thermal insulation measures are adopted, so that the percentage of the nursery stocks, which are planted in autumn and are frozen to death and frost-bitten in winter, of early bearing walnuts is reduced from 10-15% to less than 5%, so that the survival rate of the nursery stocks planted in autumn is greatly improved; and by virtue of reasonably-dug planting pits and density control, the nursery stocks, planted in autumn, of the early bearing walnuts have the advantages of favorable tree vigor, short fruit bearing time and higher fruit bearing percentage, so that the economic benefits of the walnut are greatly improved.

Description

The method that a kind of morning, real Walnut Autumn was planted

Technical field

The invention belongs to agriculture livestock and poultry cultivation field, the method that especially a kind of morning, real Walnut Autumn was planted.

Background technology

Walnut is classified as with its abundant nutrition and unique local flavor first of the world's four large dry fruits, and is very popular.Planting of walnut is divided into that the spring plants and two kinds of autumn cultivations by the time: planting spring is to plant before Sprout period after soil thaws; Autumn plants and to refer to plant before freeze-up to soil behind the nursery stock fallen leaves in autumn.Autumn the walnut trees of planting have rudiment in spring in next year early, the fast and healthy and strong characteristics of growth, but there is winter in the walnut of planting autumn frostbite is serious, survival rate is low shortcoming.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art part, provide a kind of can Effective Raise fall planting walnut survival rate, reduce real walnut planting technique method morning of frostbite in winter.

The object of the present invention is achieved like this:

The method that a kind of morning, real Walnut Autumn was planted may further comprise the steps:

(1) digs planting pit: dig length and width, deeply be respectively the planting pit of 50 * 50 * 50cm at field planting point;

(2) plant with the selection of nursery stock: it is above and root system is complete to select grafting mouth young sprout to reach 80cm, and main root length is more than 20cm, and the nursery stock with the lateral root more than 10 is used nursery stock as planting;

(3) planting density: be advisable with 4 * 5m or 5m * 6m with seeding row spacing;

(4) root system pruning and processing: the main root bottom that will plant with nursery stock cuts flat, and removes splitting part and damaged portion; The root system with nursery stock of planting is placed in the green dense cellulose solution of 15mg/l and soaked 10 days;

(5) plant: in planting pit, fill first the organic manure of half height, and it is piled the mound shape, will plant and put into the hole with nursery stock, its root system is distributed on the interior mound in hole with evenly unfolding; Then banket around root system, after collar was buried, it was in fact heavy gently to step on, and then waters sufficient water.

(6) covering with plastic film: every the root of using nursery stock of planting after watering covers 1 square metre mulch film, and with tight with soil pressure around the mulch film, the mulch film of covering should present with the center at nursery stock place lower, all around high pit shape;

(7) rich water quality management: before the rudiment in spring, water water one time, ooze lower after earthing 3-5cm again;

(8) winter protection in winter: nursery stock is overwhelmed to the opposite direction of grafting mouth, and at the anti-dry frozen ground about landfill 20cm on the nursery stock.

And described step (5) is tackled to plant when planting and is carried out classification with nursery stock, and transplanted seedling tree at the same level together.

Advantage of the present invention and good effect are:

The present invention is by selecting good nursery stock, scientifically seedling root being processed and taked rational method for planting and Insulation, freeze to death the in the winter time percentage of frostbite of nursery stock of planting of real Walnut Autumn early is reduced to below 5% by 10～15%, has greatly improved the survival rate of planting nursery stock autumn.Rationally dig the control of planting pit and density and can make reality walnut nursery stock morning of planting autumn have good tree vigo(u)r, the as a result time of lacking and higher fruiting rate, greatly improved the economic benefit of walnut.

Embodiment

The below is described in detail embodiments of the invention; Need to prove that present embodiment is narrative, is not determinate, can not limit protection scope of the present invention with this.

1, dig planting pit:

At first level land, table soil and subsoil should be placed respectively when leveling land, whole good after first with the subsoil backfill, the backfill table is native and fill with permeable heavy reality again.Dig length and width, deeply be respectively the planting pit of 50 * 50 * 50cm at heavy real field planting point, plant trees again.

2, plant with the selection of nursery stock:

Select good purebred nursery stock to use nursery stock as planting.Plant with nursery stock require its grafting mouth young sprout to reach more than the 80cm and root system complete, main root length has the lateral root more than 10 more than 20cm.Plant with should presenting fresh white under the master of nursery stock, the lateral root epidermis, and without going rotten and phenomenon of losing water; The position of planting with seedling grafting should engage firmly, and without damage by disease and insect, the branch lignification is ripe high, without the stripping phenomenon.

3, rational density

Early real walnut planting density can not be too large, and seeding row spacing is advisable with 4 * 5m or 5m * 6m, also can plan first dense planting seeding row spacing 3m * 4m, finally changes 6m * 8m into.The reasonable disposition pollinizers can be every a plant strain or every the 4 row delegation pollinizers of planting of 4 strains.Pollinizers and main breed ratio are 1: 4～6.

4, root system pruning and processing:

The main root bottom of planting with nursery stock is cut flat with shrub and hedge trimmer, remove splitting part and damaged portion, be beneficial to the recovery of root system behind the transplanted seedling tree and the healing at the place of being completely cured; The root system with nursery stock of planting is placed in the green dense cellulose solution of 15mg/l and soaked 10 days, to promote to form new root, improve survival rate.

5, plant

Should will carry out split pole with nursery stock to planting when planting, transplanted seedling tree at the same level makes the rear sapling up-growth of cultivation consistent together, is convenient to management.In planting pit, fill first the organic manure of half height when planting, and it is piled the mound shape, will plant and put into the hole with nursery stock, its root system is distributed on the interior mound in hole with evenly unfolding; Then banket around root system, after collar was buried, it was in fact heavy gently to step on, and then waters sufficient water.

6, covering with plastic film

In order to improve ground temperature, keep soil moisture, to promote Survival rate of nursery stock, plant with 1 square metre of mulch film in the root covering of nursery stock for every after watering, and with tight with soil pressure around the mulch film.The mulch film that covers should present with the center at nursery stock place lower, and high pit shape all around is in order to collect rainwater when precipitation.

7, rich water quality management

Water water one time before the rudiment in spring that autumn plants, ooze lower after earthing 3-5cm again, pluck in order to the guarantor.

8, winter protection in winter

Take mounding to improve the tolerance to cold of trees, nursery stock will be overwhelmed to the opposite direction of grafting mouth when burying soil, otherwise young sprout easily causes splitting, and at the anti-dry frozen ground about landfill 20cm on the nursery stock.
