Abstract

The invention discloses a pear grafting and planting method. The method comprises the following steps that cultivated land is constructed, seedlings are planted in batches, and single-bud grafting is carried out with the first batch of seedlings serving as rootstocks and the second batch of seedlings serving as scions. By means of the grafting method, the survival rate is 97%, the grafting survival rate is greatly improved, and the generation of abnormal branches is avoided.

Description

A kind of pear-tree grafting implantation methods

Technical field

The invention discloses a kind of pear-tree grafting implantation methods, are related to nursery fruits and vegetables field of planting.

Background technology

Pear is a kind of wide ace-high fruit, various in style, the main implantation methods of pear tree during grafting, but is passed at present The grafting method of system is all to select the age of tree pear tree of more than 5 years as stock, and it is low to there is graft survival rate, and growth is fast Degree is slow, and in order to the survival rate for ensureing grafting mostly is polygerm grafting, so results in and have in the scion for surviving the direction of growth Contrary bud branch, so may result in the generation of abnormal branch, need later stage artificial treatment, not only waste time and energy, and can also directly affect The harvest of pear.

The content of the invention

The present invention devises a kind of pear-tree grafting implantation methods, comprises the following steps：

（1）Sand loam is selected, per mu applies quick lime 50-100kg, deep plough 20-35cm, shines carclazyte earth, promotes soil to dredge Pine, while utterly destroying soil disease pest；

（2）In the middle ten days January, take at least 5 kinds pear tree seedlings and be planted in through step（1）On the soil of process, spacing in the rows be 4 × 6m, the stem of seedling is slightly 0.5-1.0cm；

（3）When the seedling of first the pear tree grows to 30-40cm, the bud head scissors on its top is cut off except 2- 3cm, and paraffin is coated, while removing branch and leaf of the length more than 15cm, Second Year mid-March, cut off plant top 5-8cm, coats paraffin, and removes branch of the length more than 30cm and leaf；

（4）The seedling plantation is grown into after first pear tree for 2 years later, starts to plant second batch pear tree seedling, described The implantation time of the seedling of second batch pear tree is the middle ten days January, and spacing in the rows is 2 × 3m, and the stem of seedling is slightly 0.5-1.0cm；

（5）When the seedling of second batch pear tree highly grows to 60-70cm, during the thick 1.0-1.2cm of stem, start grafting, grafting period It is stable at 20-29 DEG C for temperature, illumination soft or cloudy afternoon 5:00-7:00 carries out the step of grafting, grafting is：

A, the full healthy and strong simple bud of second batch pear tree is selected, the knife of chamfered forward one at 2-2.5cm below eye, into 45 degree of angles Inclined-plane, prunes one layer of epidermis, finally in the branch other end away from bud point 0.5- from the reverse side of bud point at bud point 0.5-0.8cm A knife is splayed at 0.8cm to segment, the incision of scion is applied and spread by the simple bud of the lopping bar of band one for obtaining as scion The naa solution of 300ppm；

B, prune a segment table skin in first the pear tree seedling trunk side, depth reaches xylem, scabbles tangent plane, so After the vertical cut one that lets droop indulge mouth, otch is inserted into the scion obtained by step A, make its forming layer and forming layer of stock or so Both sides are all alignd, and often enclosing to be connected from bottom to top from the bottom of grafting part with film band carries out colligation, and in scion and stock Interface coats the paraffin of thin layer, and at the whole grafting on the outside of gently wrap up in last layer and prick and have perhaps lacunary black thin Film, when spike length waiting goes out sprouting, removes plastic sheeting.

Beneficial effect：The present invention utilizes simple bud grafting, it is to avoid the generation of abnormal branch after grafting survival, and leads to before grafting Past top, prune and avoid stock from growing exceeding prosperous, can well retain the nutrient in stock, more conducively scion survive and Growth, substantially increases the survival rate of grafting.

Specific embodiment

The preferred embodiments of the present invention are illustrated below, it will be appreciated that preferred embodiment described herein is only used In the description and interpretation present invention, it is not intended to limit the present invention.

（1）Sand loam is selected, per mu applies quick lime 50-100kg, deep plough 20-35cm, shines carclazyte earth, promotes soil It is loose, while eliminating soil disease pest；

（2）In the middle ten days January, take 5 kinds of pear tree seedlings and be planted in through step（1）On the soil of process, spacing in the rows is 4 × 6m, real The stem of raw seedling is slightly 0.5-1.0cm；

（5）When the seedling of second batch pear tree highly grows to 60-70cm, during the thick 1.0-1.2cm of stem, start grafting, gas during grafting Temperature is stable at 20-26 DEG C, the afternoon 5 at cloudy day:00 carries out the step of grafting, grafting is：

A, the full healthy and strong simple bud of second batch pear tree is selected, the knife of chamfered forward one at 2-2.5cm below eye, into 45 degree of angles Inclined-plane, prunes one layer of epidermis, finally in the branch other end away from bud point 0.5- from the reverse side of bud point at bud point 0.5-0.8cm A knife is splayed at 0.8cm to segment, used as scion, the naa of 300ppm is spread in painting to the simple bud of the lopping bar of band one for obtaining Solution；

The present invention in Hefei City Lujiang County Guo He towns, tested by life, and 60 plants of pear trees of grafting, scion is germinateed 58 plants, survival rate Up to 97%, there is not abnormal branch in the developmental process in later stage in scion, grows fine, without the need for artificial pruning.

Claims

1. a kind of pear-tree grafting implantation methods, it is characterised in that comprise the following steps：

A, the full healthy and strong simple bud of second batch pear tree is selected, the knife of chamfered forward one at 2-2.5cm below eye, into 45 degree of angles Inclined-plane, prunes one layer of epidermis, finally in the branch other end away from bud point 0.5- from the reverse side of bud point at bud point 0.5-0.8cm A knife is splayed at 0.8cm to segment, how scion is placed in 200ppm by the simple bud of the lopping bar of band one for obtaining as scion 5h is soaked in acetic acid solution；

B, prune a segment table skin in first the pear tree seedling trunk side, depth reaches xylem, scabbles tangent plane, so After the vertical cut one that lets droop indulge mouth, otch is inserted into the scion obtained by step A, make its forming layer and forming layer of stock or so Both sides are all alignd, and often enclosing to be connected from bottom to top from the bottom of grafting part with film band carries out colligation, and in scion and stock Interface coats the paraffin of thin layer, and at the whole grafting on the outside of gently wrap up in last layer and prick and have perhaps lacunary black Plastic sheeting, when spike length waiting goes out sprouting, removes plastic sheeting.
