A high-light-efficiency double-plant thin V-shaped cultivation method for moderately dense peach

Abstract

The invention discloses a high luminous efficiency double-strain fine V-type cultivation method for peach appropriate close planting, which relates to fruit tree cultivation method field. The method comprises the steps of planting more than 2 peach sprouts along row direction in certain interval to form a small included angle perspective V-type planting, in this way, the branch set can be conveniently configured; the ventilation and light transmission condition can be improved; and the output can be improved; in the perspective of density, the single strain Y-type trunk along row direction is moved transversally to half of the plant spacing, in this way, the branch set category is increased; the time of peach economic output is shortened; and water, fertilizer, light, air and land can be used in the most fully and reasonable way.

Description

technical field [0001] The invention relates to a fruit tree cultivation method, in particular to a high-light-efficiency double-plant fine V-shaped cultivation method for moderately densely planting peaches. Background technique [0002] Peach is a seasonal fruit that is not resistant to storage. It is one of the bulk fruits that people love and is rich in nutrition. Since peach seedlings can bear fruit in the second year after planting, it is required to quickly form during cultivation so as to form yield as soon as possible. This is why Higher requirements are put forward for the colonization mode and individual plant shaping. There are two main types of traditional peach tree shapes, namely, the natural happy shape and the main trunk sparse layer delayed happy shape, neither of which is suitable for dense planting, so the early production cannot be formed. As a relatively advanced cultivation mode of dense plants and wide rows, the Y-shaped single plant (also known as t...

Problems solved by technology

Therefore, in addition to the defects of the Y shape of a single plant, there are also other serious defects such as the poor ability of sustainable regeneration and sustainable results of branches due to excessive density.

Especially if the angle with the ground is too small, the stem will inevitably be too long, resulting in the extension of the part, which is not only particularly unsuitable for mechanized operation, but also lowers the land utilization rate.

In addition, there is also a similar distribution of dense plant wide row cultivation mode in foreign countries, the plant spacing can reach 1 meter, and the odd and even plants are also inclined to the two sides of the row at a small angle, but to be precise, it is a kind of Rotate 90 degrees so that the two main branches are inclined to the sides along the row in a thin Y-shaped single plant (here we call it "single-plant rotated thin Y-shaped"), and it is difficult to effectively arrange branch groups between the two main branches. In the north-south planting mode, the branch group at this part is the branch group with the best orientation and the highest light efficiency, which shows that its defects are more obvious
