Problems solved by technology

Due to the limitation of the height of the greenhouse, the common tree crowns currently used in production are relatively high, which are not suitable for application in greenhouse cultivation; at the same time, the greenhouse is a relatively high-temperature, high-humidity, weak-light regional environment, and it is necessary to develop a A tree shape with high light efficiency suitable for greenhouse cultivation, dwarfed crown, good ventilation and light transmission

Embodiment 1

[0029] The present embodiment adopts the method for conventional open-field cultivation of pear trees, and the variety is "Cuiguan", which includes the following steps:

[0030] (1) Determine the stem and manage the seedlings of the year. Select strong seedlings for colonization, and the fixed height is 40-50cm. When most of the long shoots reach more than 60cm for the first time and are close to the end of the shoot, pick the heart and pull it into a bow shape to change the dominance of the top and promote the formation of new long shoots from the middle and short shoots on the main trunk. Do the same when the new long shoots are close to stopping. Untie all the pulled branches 1 to 2 months before the leaves fall, so that the angle of the branches will naturally rise. By the end of the year, many long shoots with strong growth, 80-100cm in length, 30°-45° base angle, 90° waist angle and 45° tip angle can be cultivated. When pruning in winter, select 2 to 4 long shoots as ...

Embodiment 2

[0037] Present embodiment adopts the method for pear tree greenhouse cultivation, and kind is ' emerald crown ', comprises the following steps:

[0038] (1) Determine the stem and manage the seedlings of the year. Select strong seedlings for colonization, and the fixed height is 40~50cm. When most of the long shoots reach more than 60cm for the first time and are close to the end of the shoot, pick the heart and pull it into a bow shape to change the dominance of the top and promote the formation of new long shoots from the middle and short shoots on the main trunk. Do the same when the new long shoots are close to stopping. Untie all the pulled branches 1 to 2 months before the leaves fall, so that the angle of the branches will naturally rise. By the end of the year, many long shoots with strong growth, 80-100cm in length, 30°-45° base angle, 90° waist angle and 45° tip angle can be cultivated. When pruning in winter, select 2 to 4 long shoots as the backbone branches, cu...

Abstract

The invention belongs to the field of pomology and fruit tree ecology and discloses a pear tree form shaped like a Chinese character 'Mi' and a shaping method thereof. The tree form is composed of one main trunk, eight backbone branches, and 200-240 branch groups. The eight backbone branches use the main trunk as a central point and respectively extend toward 8 directions so as to form a tree body framework shaped like a Chinese character 'Mi'. The base angle of the backbone branches is 30-45 degrees. The waist angle is 75-90 degrees. The tip angle is 40-50 degrees. Each backbone branch is provided with 25-30 branch groups which comprise a large-scale branch group, 3-4 medium-sized branch groups and 20-25 small branch groups. The tree form integrates the advantages of a pear canopy frame type tree form and an open-heart-shaped tree form, and has the advantages of being shortened in tree crown, balanced and stable in tree vigor, strong in wind resistant capacity of fruits, even in size of fruits, good in quality of fruits, high in commodity rate, simple, convenient and labor-saving to trim, and the like. The pear tree form is suitable for being cultivated in southeast coastal areas where typhoons occur often.

Description

technical field [0001] The invention relates to a "rice"-shaped tree shape of a pear tree and a shaping method thereof, belonging to the fields of fruit tree cultivation and fruit tree ecology. Background technique [0002] The tree shape of pear trees is an important part of pear tree cultivation. Different tree shape structures have a great influence on the management difficulty, tree vigor, yield and quality of pear trees. At present, the main tree shapes used in the production of pear trees in my country include evacuated layered, spindle, happy, and scaffolding tree shapes. The evacuated layered shape is the traditional tree shape of northern pear trees. It has a tall crown, a strong skeleton, a long lifespan, high and stable yields, but it has disadvantages such as inconvenient management and uneven fruit quality. The spindle shape (natural spindle shape, improved spindle shape, etc.) has many advantages such as fast forming, early fruit and high yield, and easy manag...
