Problems solved by technology

Although artificial control can effectively control the occurrence of branch diseases, it is time-consuming and labor-intensive, and the wounds formed on the main trunk also seriously weaken the tree vigor, which obviously affects the normal growth of pear trees.
Chemical control that increases the amount and frequency of use of chemical pesticides not only cannot achieve complete control, but also brings hidden dangers to the food safety of pome fruit while increasing the cost of chemical pesticides.
[0006] And, do not find suitable stock that reduces pear tree disease at present, therefore, still can't completely overcome the generation of trunk disease and insect pest of pear tree even by the mode of grafting

Embodiment 1

[0049] A kind of pear tree cultivation method that prevents pear tree trunk disease, specifically as follows:

[0050] 1) Build a horizontal scaffolding

[0051] Use 3.3m×0.14m×0.14m cement columns as corner columns, use 2.7m×0.10m×0.10m cement columns as side columns, and use 2.0m×0.06m×0.06m cement columns at intervals of 3 meters. Top pillars, build a building with an area of ​​3335m 2 The horizontal scaffolding has a surface height of 1.8 meters.

[0052] 2) Cultivation of disease-resistant rootstock seedlings

[0053] Dig a 1-meter-wide and 0.5-meter-deep planting ditch along the planting row at intervals of 3.6 meters, lay 30 cm of straw on the bottom of the ditch, backfill the soil on the straw to 10 cm from the topsoil, and spread 20-40 Dan of decomposed organic fertilizer per mu , potassium sulfate compound fertilizer 40-50 kg, and then take topsoil to fill the ditch level, and then mark the planting points every 4 meters on the planting row, sow 3 to 5 Sichuan pea...

Embodiment 2

[0069] A kind of pear tree cultivation method that prevents pear tree trunk disease, specifically as follows:

[0070] 1) Cultivation of disease-resistant rootstock seedlings

[0071] Dig a 1-meter-wide and 0.5-meter-deep planting ditch along the planting row every 5 meters apart, lay 30 cm of straw on the bottom of the ditch, backfill the soil on the straw to 10 cm from the topsoil, and spread 20-40 Dan of decomposed organic fertilizer per mu , potassium sulfate compound fertilizer 40-50 kg, and then take topsoil to fill the ditch level, and then mark the planting points every 5 meters on the planting row, sow 3 to 5 Sichuan pear seeds at each planting point in the winter of 2010, and sow The depth is 3 to 5 cm. After sowing, water thoroughly and cover with transparent plastic film. In the spring of the second year, after the seeds germinate and emerge from the ground, remove the mulch film quickly, keep a strong rootstock seedling and tie it up with a bamboo pole to grow st...

Abstract

The invention discloses a pear tree cultivation method for preventing disease damage of the trunks of pear trees. The method comprises the following steps that firstly, pyrus pashia trees high in resistance to pear tree branch and trunk diseases including the ring spot, the stem blight and the branch rot are selected as stock seedlings and cultured; secondly, pyrus pashia stock seedlings with the height being 1.5 m or above and the neck thickness being 1.5 cm or above are selected, and pear trees of an annual pear cultivation variety are subjected to high-position grafting with a cut grating method in the period of the later ten days of February and the early ten days of March; lastly, reasonable later-stage management and trimming pruning are carried out to complete grafting of pear trees. Pear trees cultivated with the method are minimum in branch and trunk disease incidence and disease index, highest in single plant yield and single fruit weight and high in fruit comprehensive quality; besides, labor and pesticides used for controlling branch and trunk disease damage are greatly reduced, and the safety of fruits is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and in particular relates to a pear tree cultivation method for preventing pear tree trunk diseases. Background technique [0002] Pear is one of the main fruit trees in my country, and its cultivated area and output both rank first in the world. Among various fruit trees in my country, pear tree area and output are second only to apples and citrus, ranking third. The south of the Yangtze River is a tropical and subtropical pear area, and the sand pear variety is mainly cultivated. [0003] At present, the southern sand pear mainly adopts the cultivation methods such as inverted "ge" shape shaping, trunk type fine spindle shape shaping and horizontal scaffolding shape shaping. However, no matter which plastic cultivation method is used, the rootstock is cut off at the base of the rootstock 3-5cm away from the ground, and then the cultivars are directly grafted, and the annual s...
