Tomato Y-shaped double-branch pruning method

Abstract

The invention discloses a tomato Y-shaped double-branch pruning method. The method comprises the following steps that firstly, every two supporting iron wires parallel to the moisture surface servingas a set are fixed to the place 1.8-2.2 meters from the moisture surface; a single row of tomatoes are planted in the middle of the moisture surface, the plant spacing is 35-45 centimeters, after first inflorescences occur in the plants, the first inflorescences are removed, and a side branch under each main trunk and the corresponding first inflorescences is reserved as a double-branch pruned fruiting branch; the upper end of a V-shaped vine guiding rope is fixed to every two supporting iron wires, the lower end of each V-shaped vine guiding rope is fixed to a branching part of the corresponding main trunk and side branch, so that a V-shaped plane formed by each V-shaped vine guiding rope is perpendicular to a plane formed by the two corresponding supporting iron wires, and the main trunks and the side branches wind the V-shaped vine guiding ropes respectively; all the side branches formed in the later period are removed, and when every double branches grow to the height of the supporting iron wires, pinching is conducted on the main trunks and the side branches. By means of the method, the problems can be solved that branches and leaves of infinite growing-type tomatoes in the middle and later period are too dense, the ventilation and light transmission are weak, and the operation of personnel is difficult.

Description

technical field [0001] The invention relates to the technical field of tomato pruning in plastic greenhouses, in particular to a Y-shaped double-stem pruning method for tomatoes. Background technique [0002] Tomatoes are annual herbaceous plants with semi-erect stems. According to the location of the inflorescence and the growth characteristics of the main axis, tomatoes can be divided into limited growth types and unlimited growth types. Most of the tomato varieties in the market are unlimited growth types. type tomato. Tomato axillary buds have strong meristem ability, basically each axillary bud can form side branches, and secondary and tertiary branches can be formed on the side branches. Too many branches consume a lot of nutrients, poor ventilation and light transmission, which is conducive to the occurrence of diseases and insect pests. When tomato plants grow to a certain height, plant adjustments must be made, mainly for unlimited-growing tomatoes. There are two ...
