Reshaping and cultivating method of pear tree with single trunk and two main branches

Abstract

The invention relates to a reshaping and cultivating method for a pear tree with a single trunk and two main branches. The reshaping and cultivating method specifically comprises the following steps: planting a plantlet at a 1.5m-1.7m position of the height of the trunk; selecting and remaining two strong branches or strong buds which are cultivated into two main branches reversely growing along the rows at a basal angle of 45 degrees; fixing the main braches on a horizontal shed frame when the main branches reach racking points, and inducing the extended branches of the main branches to an inducing rod which forms a 45-degree angle with the shed frame, wherein extended fruiting branch groups which are in parallel arranged and vertically extend into the rows are provided on the main branches; and gently and slowly pushing, binding and fixing the two main branches to the flat shed frame surface in autumn of the next year. The reshaping and cultivating method disclosed by the invention is quick in crown forming speed, capable of completing the crown structure cultivation 3 years after the planting to begin to enter into an initial fruiting period which is increased year by year, and high in fruit quality uniformity. Meanwhile, the pruned crown does not contain secondary branches, and therefore, the reshaping and cultivating method has the advantages of being simple to prune, convenient to manage, good in ventilation and light transmission condition and the like.

Description

technical field [0001] The invention belongs to the technical field of fruit tree shaping and cultivation, and in particular relates to a method for shaping and cultivating pear trees with one trunk and two main branches. Background technique [0002] Pear is a plant of the genus Pyrus in the family Rosaceae, a perennial deciduous fruit tree, arbor, with oval leaves, white flowers, juicy and edible fruits. Harvest when the fruit is ripe between August and September, use fresh or slice and dry. The main varieties are Qiuzi pear, white pear, sand pear, and foreign pear, which are mostly distributed in North China, Northeast China, Northwest China and the provinces along the Yangtze River Basin. The adaptability to the external environment is stronger than that of apples. Cold tolerance, drought tolerance, waterlogging tolerance, saline alkali tolerance. Its shaping methods are mainly trellis-type happy tree shape and natural happy-shaped tree shape without trellis. [0003...

Problems solved by technology

[0004] 2. The planting density of pears with natural open-heart trellises is relatively low. In the first 5 years, the pears were mainly cultivated pears, which were put into production late, and the cost of pears was high. At present, it is still difficult to popularize pears.

However, the above method is not suitable for the special climatic conditions in Jiangsu area, and it is late in the fruiting period.
