Description

TECHNICAL FIELD

[0001] The application relates to the technical field of greenhouse cultivation support, and in particular to a horizontal greenhouse support suitable for efficient production of cherry tomato. BACKGROUND

[0002] As an important economic crop of facility agriculture, cherry tomato in a plastic greenhouse has a high yield and good benefits, and is widely planted in China. However, with the expansion of the industry scale, the technical bottlenecks of the traditional cultivation mode are increasingly prominent, which restricts the sustainable development of the industry.

[0003] Cherry tomato plants grow vigorously, and the plant height can be more than 2 meters. If the fruits touch the ground, the fruits will rot and diseases will occur frequently, so it is necessary to erect the plants by using a support. In the middle and late growth period of the tomato, the plants are heavy, and the ordinary support is difficult to bear, and the support often collapses.

[0004] There are many improvement schemes for the traditional support, but all have certain problems. The patent with the publication number CN220733705U, a hanging vine device for greenhouse tomato planting, adopts a hanging vine operation, and the distance and number of hanging ropes can be adjusted at will, but it is only limited to use in a greenhouse, and the plastic greenhouse facility is simple and cannot implement the hanging vine technology special for a greenhouse; the patents with the publication numbers CN221948844U, CN220915908U and CN214545990U mention a vine support for tomato cultivation, which can better adjust the height and direction of the vine, but it is only used for single or several tomato plants, and when used in a field, it faces the dilemma of high production cost and insufficient practicality, and has low practicality; the patent with the publication number CN219395689U discloses a tomato planting support, which can be used for tomato hanging vine cultivation in a plastic greenhouse, and facilitates the fixation of several tomato vines in a row, and improves the fixation efficiency of single row plants, but the support structure is thin, and the anti-toppling capacity is insufficient, especially in the fruit swelling period.

[0005] CN205567249U discloses a "human" frame system, which is the current mainstream support structure. The frame structure is simple, easy to build, low in cost and reusable. Bamboo poles are used as materials, two bamboo poles are inserted into the ground at an angle on the ridge, the top of the two bamboo poles are fixed to each other, and the two bamboo poles form a "human" shape. The tomato vines are fixed on the bamboo poles, and a horizontal bamboo pole is connected to the top of the "human" frame in the same column. Although the structure has the advantages of simple construction and low cost, it has systematic defects. The bamboo pole insertion structure has poor load-bearing capacity, and the frame body is at high risk of collapse in the late growth stage of the plants. To avoid the impact of the "human" frame of cherry tomatoes on field operations such as plowing, the "human" frame needs to be rebuilt every year, which can only be used for one crop of plants, has low utilization rate, and increases labor costs. More seriously, the upper vines of the "human" frame are intertwined with each other, which is not conducive to uniform spraying of liquid medicine, and the disease and pest control effect is poor. At the same time, the dense upper part leads to poor ventilation and light transmission of the middle and lower parts of the plants, inducing poor fruit development and high incidence of diseases.

[0006] These technical defects form a complex chain reaction, from insufficient load-bearing capacity leading to increased investment in frame reconstruction, to reduced field management efficiency leading to increased disease and pest infestation, to increased pesticide use leading to increased soil pollution. The existing technology system has been difficult to meet the requirements of modern agriculture for high yield, high efficiency and ecological friendliness. Therefore, the development of a new type of horizontal shed frame has become a key breakthrough to solve the problem of cherry tomato cultivation in plastic greenhouses, and has important significance for promoting the development of modern facility agriculture.

Referring to Figure 1 With Figure 2 , the horizontal shed frame suitable for efficient production of greenhouse cherry tomatoes is also in the south-north direction like the greenhouse, and the shed frame is horizontal with a height of 2 m.

[0034] The horizontal shed frame comprises a plurality of rows of support columns 1 arranged at intervals, and the support column 1 is exemplified by a cement column with good support performance. The lower end of the support column 1 is deeply buried in the soil, and the upper end is exposed 2 m above the ground. The thickness of the support column 1 is 10 cm X 10 cm. The support column 1 is divided into a plurality of rows arranged at intervals along the south-north direction, and a plurality of support columns 1 are arranged at intervals along the east-west direction in each row.

[0035] Taking a plastic greenhouse with a span of 8 m and a length of 50 m as an example, the distance between adjacent support columns 1 in the east-west direction is 2 m, and the distance between adjacent support columns 1 in the south-north direction is 10 m. That is, there are six rows of support columns 1 in the south-north direction, and each row of support columns 1 comprises four support columns 1. The support columns 1 at the two ends of the shed frame are pre-buried ground anchors, and the lead lines are tensioned.
