Tomato F-shaped pruning method

Abstract

The invention provides a tomato F-shaped pruning method. When tomato plants grow to 25-35 centimeters, several inverted-Y-shaped supports, vertical rods and two transverse rods are adopted for constituting a pruning structure, when first inflorescences appear on the plants, the first inflorescences are removed, main trunks and one lateral branch of each first inflorescence are reserved as bearingbranches, the main trunks wind the vertical rods, the lateral branches wind the transverse rods, and the lateral branches are subjected to pinching after two spikes of fruits are reserved; the main trunks are subjected to pinching after growing to intersections of the inverted-Y-shaped supports, one lateral branch is reserved and winds the transverse rod at the upper portion, and pinching is conducted after two spikes of fruits are reserved. According to the method, single-row planting is adopted, the planting density is increased, the growth space of tomatoes in the middle and later periods is also expanded, ventilation and lighting of the plants are facilitated, the humidity and the occurrence of diseases and insect pests are reduced, the number of fruits borne on the tomato plants is increased, each tomato plant can at least bear 8-10 spikes of fruits, and the yield of the tomatoes is increased.

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...

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.
