Problems solved by technology

[0003] At present, the prevention and control of trunk diseases of pear trees is mainly based on the combination of chemical control and artificial control. Although it can effectively control the occurrence of branch diseases, it is time-consuming and laborious, and the wounds formed on the trunk have seriously weakened the vigor of the tree. , significantly affect the normal growth of pear trees
Simultaneously, do not find suitable rootstock that reduces pear tree disease at present, therefore, still can't completely overcome the generation of the trunk disease and insect pest of pear tree even by the mode of grafting, simultaneously, also generally exist the low situation of survival rate in the pear tree grafting process

Embodiment 1

[0020] A method for cultivating pear trees for preventing pear trunk diseases, comprising the steps of:

[0021] S1. Select the Sichuan pear with a seedling height of more than 1.5 m, a stem diameter of about 1.0 to 2.0 cm, good adaptability, and strong resistance to pear tree branches and trunk diseases as a rootstock seedling;

[0022] S2. From late February to early and mid-March, cut the rootstock at a height of 50cm from the ground, then use a grafting knife to split vertically downward at one-third of the cross-section of the cut, and select annual Fengshui pear branches with full leaf buds To make a scion, cut a knife under the leaf bud, cut off the phloem, and expose the cambium. The cut surface is about 3 to 4 cm long, and the cut surface is smooth. Then, beveled at the end of the long cut surface to form a short cut surface at an angle of 45 degrees. Cut the cut surface of the scion After dipping in the mixture of 0.03 forchlorfenuron + 0.07% moonshin at a medium spe...

Embodiment 2

[0026] A method for cultivating pear trees for preventing pear trunk diseases, comprising the steps of:

[0027] S1. Select the Sichuan pear with a seedling height of more than 1.5 m, a stem diameter of about 1.0 to 2.0 cm, good adaptability, and strong resistance to pear tree branches and trunk diseases as a rootstock seedling;

[0028] S2. From late February to early and mid-March, cut the rootstock at a height of 50cm from the ground, then use a grafting knife to split vertically downward at one-third of the cross-section of the cut, and select annual Fengshui pear branches with full leaf buds To make a scion, cut a knife under the leaf bud, cut off the phloem, and expose the cambium. The cut surface is about 3 to 4 cm long, and the cut surface is smooth. Then, beveled at the end of the long cut surface to form a short cut surface at an angle of 45 degrees. Cut the cut surface of the scion After dipping in the mixed solution of 0.06% forchlorfenuron + 0.05% moonshin at medi...

Embodiment 3

[0032] A method for cultivating pear trees for preventing pear trunk diseases, comprising the steps of:

[0033] S1. Select the Sichuan pear with a seedling height of more than 1.5 m, a stem diameter of about 1.0 to 2.0 cm, good adaptability, and strong resistance to pear tree branches and trunk diseases as a rootstock seedling;

[0034] S2. From late February to early and mid-March, cut the rootstock at a height of 50cm from the ground, then use a grafting knife to split vertically downward at one-third of the cross-section of the cut, and select annual Fengshui pear branches with full leaf buds To make a scion, cut a knife under the leaf bud, cut off the phloem, and expose the cambium. The cut surface is about 3 to 4 cm long, and the cut surface is smooth. Then, beveled at the end of the long cut surface to form a short cut surface at an angle of 45 degrees. Cut the cut surface of the scion After dipping in the mixed solution of 0.045% forchlorfenuron + 0.06% moonshin at med...

Abstract

The invention relates to the technical field of pear tree cultivation, in particular to a pear tree cultivation method for preventing pear tree trunk diseases, which comprises the following steps: selecting pyrus pyrifolia which is 1.5 m or more in seedling height, about 1.0-2.0 cm in stem thickness, good in adaptability and strong in pear tree branch and trunk disease resistance as stock seedlings; the method comprises the following steps: cutting a scion on a rootstock seedling, placing the cut surface of the scion in a mixed solution of 0.03-0.06% forchior fennron and 0.05-0.07% moonlight flower element, quickly dipping, grafting on the rootstock seedling at a high position by adopting a cut grafting method, spraying a grafting promoting solution at the joint of the scion and the rootstock, and preparing the grafting promoting solution from amino-oligosaccharin, a fructus psoraleae seed extract, vitamin B12 and deionized water. The grafting survival rate of the pear trees can be remarkably increased, and the occurrence rate of trunk diseases in the pear tree cultivation process is reduced.

Description

technical field [0001] The invention relates to the technical field of pear tree cultivation, in particular to a pear tree cultivation method for preventing pear tree trunk diseases. Background technique [0002] Pear tree disease is an important obstacle affecting the yield and quality of pear fruit. At present, it is more harmful to the production of pear trees. The most common diseases of pear tree trunk diseases mainly include pear ring spot, pear rot and pear dry rot. Serious It will cause the branches to die. [0003] At present, the prevention and control of trunk diseases of pear trees is mainly based on the combination of chemical control and artificial control. Although it can effectively control the occurrence of branch diseases, it is time-consuming and laborious, and the wounds formed on the trunk have seriously weakened the vigor of the tree. , significantly affect the normal growth of pear trees. Simultaneously, do not find suitable stock that reduces pear t...
