Embodiment 1

[0026] A kind of pear tree cultivation management and shaping method, described method comprises the steps:

[0027] (1) In the pear orchard, a pear tree planting ridge with a width of 2 meters is set up, and the row spacing drainage ditch is arranged on both sides of each pear tree planting ridge, and the row spacing drainage ditch is connected with the general drainage ditch around the pear orchard. Pear trees are planted on the central line of the pear tree planting ridge at a plant spacing of 2.5 meters;

[0028] (2) Use the following method to reshape it:

[0029] ①The first year: Prune the trunk of the pear tree planted in the autumn of the previous year or the spring of the current year to a height of 0.8 meters, cultivate the first germinated pear head into the main trunk, and select the branches formed at the original trunk at about 0.6 meters. Leave two buds growing in opposite directions to cultivate the lower main branch, and the unidirectional extension length of...

Embodiment 2

[0036] A kind of pear tree cultivation management and shaping method, described method comprises the steps:

[0037] (1) In the pear orchard, a pear tree planting ridge with a width of 3 meters is set up, and row spacing drainage ditches are arranged on both sides of each pear tree planting ridge, and the row spacing drainage ditch is connected with the general drainage ditch around the pear orchard. Pear trees are planted on the central line of the pear tree planting ridge by 2 meters apart;

[0038] (2) Use the following methods to reshape it:

[0039] ①The first year: Prune the trunk of the pear tree planted in the autumn of the previous year or the spring of the current year to a height of 0.8 meters, cultivate the first germinated pear head into the main trunk, and select the branches formed at the original trunk at about 0.6 meters. Leave two buds growing in opposite directions to cultivate the lower main branch, and the unidirectional extension length of the lower main...

Embodiment 3

[0047] A kind of pear tree cultivation management and shaping method, described method comprises the steps:

[0048] (1) In the pear orchard, a pear tree planting ridge with a width of 2.5 meters is set up, and row spacing drainage ditches are arranged on both sides of each pear tree planting ridge, and the row spacing drainage ditch is connected with the general drainage ditch around the pear orchard. Pear trees are planted on the central line of the pear tree planting ridge at a plant spacing of 2.2 meters;

[0049] (2) Use the following methods to reshape it:

[0050] ①The first year: Prune the trunk of the pear tree planted in the autumn of the previous year or the spring of the current year to a height of 0.8 meters, cultivate the first germinated pear head into the main trunk, and select the branches formed at the original trunk at about 0.6 meters. Leave two buds growing in opposite directions to cultivate the lower main branch, and the unidirectional extension length ...

Abstract

The invention discloses a pear tree cultivating, managing and shaping method. Through foliage top-dressing, the yield of pears can be effectively increased. At the flowering stage, a boric acid aqueous solution of which the volume percentage is 2-3% is sprayed to leaf surfaces, so that coming off of flowers can be effectively reduced, and the percentage of fertile fruits can be increased. Throughreasonable shaping of pear trees, dwarfing culture of the pear trees can be realized, facility cultivation in shelter from rain can be realized, and the pear tree cultivating, managing and shaping method is more suitable for cultivation in rainy places such as south of China. Through the pear tree shaping method, the branch quantity, the extending direction and the distribution level of the pear trees can be controlled, the ventilation properties and the illumination properties of a pear garden are improved, the situation that pear tree nutrition is uniformly transported to each pear branch can be guaranteed, the size of the pears can be guaranteed, and the commodity properties of the pears can be improved. The tree form is low, so that the pear trees are easy to trim by fruit growers, thepears are easy to pick by the fruit growers, and artificial operations are convenient.

Description

technical field [0001] The invention belongs to the technical field of pear tree cultivation, and in particular relates to a pear tree cultivation management and shaping method. Background technique [0002] Pear (Pyrus L.) is an important economic crop in my country, and its cultivated area and output both rank first in the world. Pear fruit has high nutritional value, crisp and juicy, sweet and sour taste, and has certain medical value, so it is loved by consumers. In the cultivation technology management of pear trees, the tree structure is directly related to the lighting efficiency and nutrient distribution of the tree body, thereby affecting the fruit quality, and it occupies a very important position in the pear tree cultivation system. At present, in the domestic pome fruit industry, labor costs have increased greatly. In the past, the large-crown tree shape and some tree shapes with high technical requirements required a long period of time, complicated management,...
