Description

Technical Field

[0001] This invention relates to the field of tomato planting tool support technology, specifically to an adjustable support for tomato growth. Background Technology

[0002] Tomatoes are annual or perennial herbaceous plants, widely loved for their sweet and sour taste. The best time to plant tomatoes is generally in spring, from April to May. Choose well-drained soil, till it, and apply an appropriate amount of fertilizer as base fertilizer. Select disease-resistant and vigorous tomato varieties, sun-dry and soak the seeds to sterilize them, then sow them directly on the soil, water, and cover with soil. With the continuous improvement of tomato cultivation techniques, the main stem of individual tomato plants is becoming taller, with more lateral branches, and the weight of the fruits is also increasing. However, the branches of tomato plants are relatively weak, necessitating trellising to prevent the plants from collapsing.

[0003] Most existing tomato trellises use hooks to support the fruit. As tomatoes grow, the fruit continues to expand and increase in weight, making it impossible to adjust the trellis according to the growth of the tomato bunches. This affects the growth of the tomatoes and makes it difficult to promote their use.
