Abstract
The invention discloses an improved method for walnut high grafting and excellent changing, which comprises the steps of selecting and processing rootstocks, selecting scions, grafting operation, grafting subsequent management and the like, and combines the operation of reserving auxiliary culture branches: on the one hand, the excessive nutrition provided by the root system can be shunted, the transpiration of the tree body is increased, the junction bleeding is reduced, the grafting young shoots are prevented from overgrowing, on the other hand, the photosynthesis can be effectively carried out, the nutrition is made to flow back to the tree body and the root system, the original root crown balance of the tree body is maintained to the maximum extent, the stress resistance of the tree body is improved, and the multiphase combination is realized, so that the survival rate of grafting is ensured, and the survival rate of grafting is improved.
Description
Technical Field
The invention belongs to the technical field of walnut cultivation, and particularly relates to an improved method for high grafting and high-quality changing of walnuts.
Background
The high grafting and high quality improvement is one of the common techniques for improving the walnut orchard at present, can quickly realize the updating of excellent varieties, promotes the orchard to enter the fruiting period in advance, and achieves the purposes of early fruiting, early high yield, and early quality improvement, yield increase and efficiency increase. But traditional high grafting trades excellent operation, owing to saw cut most branch and leaf after, can make the proportion unbalance of tree body root system and crown, lead to the nutrition insufficient, very easily cause the whole malnutrition of walnut and resistance variation, lead to the grafting survival rate low easily.
Disclosure of Invention
Based on the background, the invention provides an improved method for high grafting and high quality changing of walnuts, which can improve the grafting survival rate.
The technical scheme of the invention is as follows:
an improved method for high grafting and changing of walnuts comprises the following steps:
s1, selecting a walnut tree which is strong in growth, free of diseases and insect hazards and with the diameter at breast height below 15cm as a high grafting walnut tree;
carrying out rhizosphere topdressing, tree disc mulching and trunk insecticidal sterilization treatment on the high-grafting walnut trees;
s2: determining a grafting opening, reserving a certain amount of fostering branches for the weak branches below the grafting opening by 50cm and within 100cm from the ground, and flattening or drooping;
s3: collecting scions: selecting branches with the thickness of more than or equal to 1.5cm and the medullary rate of less than or equal to 20 percent as scions;
s4, carrying out early spring branch grafting on the actual or inferior big tree from 3 late ten days to 4 middle ten days of the month, and carrying out timely supplementary grafting according to the survival condition of the branch grafting;
s5: carrying out door opening budding in summer;
s6: in the growing season, the young shoots are fixedly bound, plucked and strengthened and mature lignified; pruning, shaping and cleaning the garden for protection after autumn; winter protection and freeze protection are carried out in early spring.
Preferably, in step S3, the scion retains 3-5 shoots.
Preferably, the trunk is sprayed with the long-acting forest protective agent in step S1.
Compared with the prior art, the invention has the beneficial effects that:
the invention provides an improved method for walnut high grafting and excellent changing, which comprises the steps of selecting and processing rootstocks, selecting scions, grafting operation, grafting subsequent management and the like, and combines the operation of reserving auxiliary culture branches: on the one hand, the excessive nutrition provided by the root system can be shunted, the transpiration of the tree body is increased, the junction bleeding is reduced, the grafting young shoots are prevented from overgrowing, on the other hand, the photosynthesis can be effectively carried out, the nutrition is made to flow back to the tree body and the root system, the original root crown balance of the tree body is maintained to the maximum extent, the stress resistance of the tree body is improved, and the multiphase combination is realized, so that the survival rate of grafting is ensured, and the survival rate of grafting is improved.
Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the invention. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of the stated features, steps, operations, and/or combinations thereof, unless the context clearly indicates otherwise.
Example 1: an improved method for high grafting and changing of walnuts comprises the following steps:
s1, selecting a walnut tree which is strong in growth, free of diseases and insect hazards and with the diameter at breast height below 15cm as a high grafting walnut tree;
carrying out rhizosphere topdressing, tree disc mulching and trunk insecticidal sterilization treatment on the high-grafting walnut trees;
in specific implementation, the trunk is also sprayed with the long-acting forest protective agent.
When the method is specifically implemented, the whole grafting process of high grafting and high quality changing can be ensured to be carried out in a sterile and harmless environment, so that the survival rate of grafting is further improved.
S2: determining a grafting opening, reserving a certain amount of fostering branches for the weak branches below the grafting opening by 50cm and within 100cm from the ground, and flattening or drooping;
the fostering branches reserved in the step can distribute excessive nutrition provided by root systems, increase transpiration of the tree body, reduce junction bleeding and prevent grafted young shoots from overgrowing on one hand, and can effectively perform photosynthesis to make nutrition flow back to the tree body and the root system, so that original root crown balance of the tree body is maintained to the maximum extent, and the stress resistance of the tree body is improved.
S3: scion collection: selecting branches with the thickness of more than or equal to 1.5cm and the medullary rate of less than or equal to 20% as scions, wherein 3-5 buds are reserved in the scions.
S4, carrying out early spring branch grafting on the actual or inferior big tree from 3 late ten days to 4 middle ten days of the month, and carrying out timely supplementary grafting according to the survival condition of the branch grafting;
s5: carrying out door opening bud grafting in summer (from 5 late months to 6 middle months approximately);
s6: in the growing season (about 6-8 months), the young shoots are fixedly bound, pinched, strong and mature lignified; pruning, shaping and clearing the garden to protect after autumn; winter protection and freeze protection are carried out in early spring.
The step is the subsequent management of grafting, and the management in the step can prevent the high-grafting walnut tree from being infected by high temperature or diseases and insect pests in winter so as to prevent the trunk part of the tree from being seriously frozen and even the serious walnut tree from dying, thereby further improving the grafting survival rate.
The above embodiments are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents thereof, and all such changes, modifications, substitutions, combinations, and simplifications are intended to be included in the scope of the present invention.
