A tomato "f" shape pruning method

Abstract

The invention provides a tomato "F"-shaped pruning method. When the tomato plant height is 25-35 cm, several "herringbone"-shaped brackets, vertical bars and two horizontal bars are used to form a pruning structure. , remove the first inflorescence, keep the main trunk and 1 lateral branch under the first inflorescence as the fruiting branch, the main trunk is wrapped around the vertical rod, the lateral branch is wrapped around the horizontal rod, and the lateral branches are left with 2 ears of fruit and then topped; the main trunk grows to " Topping after the intersection of the "herringbone"-shaped brackets, leaving 1 side branch and wrapping it on the upper crossbar, leaving 2 ears of fruit and topping. The method of the invention uses single-row planting, which not only increases the planting density, but also expands the growth space of the tomato in the middle and late stages, which is beneficial to the ventilation and lighting of the plant, reduces the occurrence of humidity and pests and diseases, and increases the number of tomato plants. Each tomato can hang at least 8 ~10 ears of fruit, improve tomato yield.

Description

technical field [0001] The invention relates to the technical field of open-air tomato pruning, in particular to a tomato "F"-shaped pruning method. Background technique [0002] The pruning method of tomato planting in the open air mostly adopts the frame method of fixing one horizontal bar on the "herringbone" frame. Tomatoes are planted in double rows, and the single stem pruning is wrapped around the two oblique bars of the "herringbone" frame. However, this method of tomato frame pruning has the following disadvantages: when the tomato plant grows to the middle and late stages, the upper leaves of the plant and the side branches that cannot be removed in time are staggered and blocked, which is not conducive to ventilation and light transmission and later plant adjustment operations; the height of the tomato trunk exceeds "people" When the height of the glyph frame is high, the trunk must be topped in time, which cannot meet the needs of further obtaining tomato yield i...

AI Technical Summary

Problems solved by technology

This method can solve the shortcomings of the "herringbone" pruning technique in the middle and later stages of the plant, such as too dense upper branches and leaves, weak ventilation and light transmission, and low yield in the later stage.
