Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of vegetable planting, and particularly relates to a seedling erecting mechanism for tomato growth. BACKGROUND

[0002] The seedling hanging is an important management technique in the process of tomato planting, and is especially suitable for tomatoes planted in facilities (such as greenhouses and sheds). The seedling hanging can make the tomato plants grow upward, fully utilize the vertical space in the facilities, increase the planting density, and improve the yield per unit area. Meanwhile, after the plants grow vertically, the leaves are more reasonably distributed, which is conducive to ventilation and light transmission. Good ventilation can reduce air humidity and reduce the occurrence of diseases. The seedling hanging enables the leaves to better receive light and produce more organic matter, thus providing sufficient nutrients for the growth and development of fruits, thereby improving the quality and yield of the fruits.

[0003] The purpose of the seedling hanging is to make the tomato seedlings grow upward around the rope. With the growth of the tomato seedlings, the top seedlings will deviate from the rope. At this time, the breeding personnel need to regularly adjust the height of the rope winding and reel, and manually wind the vine. Otherwise, the seedling hanging rope will be wound into the stem and damage the stem. However, the rope needs to be tied and knotted on the support in the early stage, which is time-consuming and laborious, and the process of adjusting the winding and reeling of the rope is relatively complicated.
