Method for pruning tomato bearing branch leaning to one side

Abstract

The invention discloses a method for pruning tomato bearing branches leaning to one side, comprising the following steps of: arranging a lifting rope vertical to ground surface beside rhizome of each plant; cultivating 5-8 bearing branches on each plant from down to up by adopting a continuous pinching and swapping method, and dragging each bearing branch onto the lifting rope of a northward adjacent plant of the plant to cause the included angle between each bearing branch and the ground surface to be 30-45 degrees. By adopting the method, the total inflorescence number of an individual plant can be improved, sunlight can be ensured to directly irradiate onto a tomato plant, photosynthesis is carried out more fully, carbohydrate accumulated on leaves of the bearing branches is easy to return into fruits, the fruits can get larger, and yield is improved. The phenomenon that the bearing branches drop and then are broken as the fruits expand and weight is increased in the later expanding stage of the fruits can be avoided. Plant height can be controlled, three-dimensional space in a shed can be fully utilized, the problem of falling seedling for multiple times can be solved, and labour can be reduced. Field transmitting condition can be improved, morbidity of the fruits can be reduced, the fruits also can be ensured to uniformly develop and be bright and glossy, and high-qualityfruit rate is improved.

Description

technical field [0001] The invention relates to the technical field of tomato cultivation in a solar greenhouse, in particular to a method for pruning tomato fruiting branches. Background technique [0002] In the process of tomato cultivation and management in solar greenhouse, plant pruning is a key technology that affects tomato yield. Tomatoes are symaxial branches, and the conventional pruning methods can be used in the following two ways: single-dry pruning and double-dry pruning. Single-dry pruning, leaving 5 to 6 ears for topping, and removing all the other side buds. Double-trunk pruning, that is, take the main stem and a vigorous side branch as the two main trunks, remove all the side branches on it, and then hang the vines separately, and then do the pruning once a week, remove the new growth from the tomato base and the leaf axils of each main trunk Newly grown lateral branches. Regardless of whether single-stem pruning or double-stem pruning is used, the foll...

AI Technical Summary

Problems solved by technology

Regardless of whether single-stem pruning or double-stem pruning is used, the following disadvantages exist: one is that the yield potential of unlimited-growing tomato varieties cannot be fully utilized; the other is that the flowering and fruiting nodes of the main branch continue to increase. The difficulty of management is constantly increasing, and the vines have to be dropped many times

In order to give full play to the growth characteristics of tomatoes, the continuous topping and pruning technology has gradually been adopted in production. The continuous topping and pruning technology can increase the total number of inflorescences per plant and increase the yield. The fruit rate is low, and at the same time, the fruiting branches cannot fully receive the sunlight, so they are easy to get sick, and in the late stage of fruit expansion, the phenomenon of falling and breaking the fruiting branches will occur due to the expansion of the fruit and the increase in weight
