Description

Technical Field

[0001] This invention belongs to the field of grape cultivation technology, specifically relating to a special grape cultivation trellis system and control method for greenhouses. Background Technology

[0002] Greenhouse grape cultivation can yield higher economic returns than open-field grape cultivation. With the improvement of cultivation technology, most grape berries are plump and compact, with excellent appearance. However, it can also lead to poor ventilation and light transmission inside the bunch. The berries inside the bunch are blocked by the outer berries, making it difficult for them to see light, resulting in poor taste and uneven taste among the berries. In addition, the moisture inside the bunch does not evaporate easily, which can easily cause the berries inside to rot, reducing the quality and economic value of the bunch. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides a special grape cultivation rack and control method for greenhouses, which can improve the ventilation and light transmission of grape bunches, prevent fruit rot, and make the taste of the whole bunch more uniform, thus effectively increasing economic benefits.

[0004] The specific technical solution adopted in this invention is as follows:

[0005] A special grape cultivation trellis for greenhouses includes a support frame for binding grapevines. The key feature is that the support frame comprises a set of crossbeams, bases, columns, and a frame body. The bases are spaced apart on the ground from front to back. The crossbeams are respectively positioned corresponding to the bases, and both ends of the crossbeams are connected to the greenhouse frame. The upper ends of the columns are flexibly connected to the crossbeams via connecting components, and the lower ends are hinged to the bases. Both ends of the frame body are connected to the columns on adjacent bases. Vibrators are installed on the columns, and the frame body has the freedom to swing to the left and right sides of the bases via the drive of the vibrators on the columns. The grapevines are bound to the frame body.

[0006] The connecting assembly includes a spring connected to the upper end of the column and a ring disposed on the upper end of the spring and fitted onto the crossbeam, wherein the crossbeam is a cylinder.

[0007] The frame is wrapped with hemp rope or cotton cloth.

[0008] The vibration frequency of the vibrator is 300-1000 Hz, and the amplitude is 0.01-0.2 mm.

[0009] A control method for a special grape cultivation rack in a greenhouse includes the following method of using the vibrator: after the first expansion period of the grapes, the vibrator is turned on intermittently on the 2nd to 4th day after each watering. The duration of each turn of the vibrator is 6-12 minutes and the duration of each turn is 10-30 minutes. The vibrator is turned on and off 4-5 times a day.

[0010] In the described method of use, the vibrator is intermittently turned on starting between 6 and 8 a.m.

[0011] A control method for a special grape cultivation rack in a greenhouse also includes intermittently turning on the vibrator after each watering as a vibration cycle. On the second or third day after completing one vibration cycle, a growth-promoting compound drug is sprayed onto the entire grape vine. The growth-promoting compound drug includes 1 volume part of a 700-800 times diluted solution of Wofengsu, 0.3-0.8 volume parts of a 400-600 times diluted solution of brassinolide, and 1.2-2 volume parts of a 30-60 times diluted solution of wood ash. The spraying amount is 350ml-500ml per vine.

[0012] The growth-promoting compound drug should be sprayed 1-2 hours before sunset in the afternoon.

[0013] The growth-promoting compound drug comprises 1 part by volume of 700 times diluted Wofengsu solution, 0.5 parts by volume of 600 times diluted brassinolide solution, and 1.5 parts by volume of 40 times diluted wood ash solution.

[0014] The preparation process of the plant ash dilution is as follows: take 1 volume part of plant ash and 30-60 volume parts of water, mix and stir, then stir every 5-8 hours, and after 30-48 hours of mixing, filter the residue and take the clear liquid for use.

[0015] The beneficial effects of this invention are:

[0016] This invention employs a vibrator mounted on a column. The upper end of the column is flexibly connected to a crossbeam, and the lower end is hinged to a base. The frame is connected to two adjacent columns and, with the help of the vibrator on the column, has the freedom to swing left and right. The frame is stably installed and can withstand relatively heavy grapevines. When the vibrator is turned on, the frame vibrates at a high frequency and low amplitude, swinging left and right in a fan shape. The grapevines tied to the frame vibrate, and the branches, leaves, and grape bunches move accordingly. The berries shake slightly, creating air channels inside the bunches without damaging them, allowing internal moisture to escape. When the berries shake, light enters the bunches, allowing the berries inside to receive sunlight, improving the taste of the berries and effectively enhancing the quality of the grape bunches, bringing greater economic benefits to fruit farmers.

[0017] Figure 1 This is a schematic diagram of the structure of the present invention;

[0018] In the attached diagram, 1 is the frame, 2 is the crossbeam, 3 is the base, 4 is the column, 5 is the frame, 6 is the vibrator, 7 is the spring, 8 is the ring, and 9 is the grapevine. Detailed Implementation

[0019] like Figure 1 As shown, a special grape cultivation trellis for greenhouses includes a support frame for binding grapevines 9. The support frame includes a set of crossbeams 2, bases 3, columns 4, and a frame body 5. The bases 3 are arranged sequentially on the ground from front to back at intervals. The crossbeams 2 are respectively arranged corresponding to the bases 3, and both ends of the crossbeams 2 are connected to the greenhouse frame 1. The upper end of the column 4 is flexibly connected to the crossbeam 2 via a connecting component, and the lower end is hinged to the base 3. Both ends of the frame body 5 are respectively connected to the columns 4 on two adjacent bases 3. A vibrator 6 is installed on the column 4 connected to one end of the frame body 5. The frame body 5 has the freedom to swing to the left and right ends of the base 3 by the drive of the vibrator 6 on the column 4. The branches of the grapevines 9 are bound to the frame body 5 in the front-to-back direction. The vibrator 6 is installed in the upper middle part of the column 4.

[0020] The connecting assembly includes a spring 7 connected to the upper end of the column 4, and a ring 8 disposed on the upper end of the spring 7 and sleeved on the crossbeam 2, wherein the crossbeam 2 is a cylinder. When the vibrator 6 is turned on, the vibrator 6 drives the column 4 to vibrate. Since the lower ends of the columns 4 connected to both sides of the same frame 5 are hinged to the base 3, and the upper ends of the columns 4 are sleeved on the crossbeam 2 by means of the ring 8 on the spring 7, the columns 4 drive the frame 5 to sway slightly left and right. The grapevines 9 on the frame 5 sway accordingly. Due to the swaying and vibration of the grape leaves and grape berries, the direction of shading is changed, and ventilation channels are formed between the grape berries, allowing light to enter the interior of the grape bunches and irradiate the berries inside. Furthermore, since the branches of the grapevine vine 9 are set along the front and back of the trellis 5, in order to promote the uniform growth of the fruit and the beautiful shape of the fruit bunch, during the thinning process, usually only one layer of fruit bunches is left on one side of the trellis 5. The fruit bunches grow in a front-to-back arrangement to prevent the fruit bunches from stacking and affecting ventilation and growth. The left and right swaying prevents the fruit bunches on the same grapevine vine 9 from colliding with each other, and avoids the fruit berries from breaking or falling off due to the large inertia of the fruit bunches and the collision between adjacent fruit bunches.

[0021] The spring 7 absorbs vibrations, reducing the kinetic energy of the vibrator 6 received by the crossbeam 2, thus keeping the frame 1 stable and unaffected.

[0022] The frame 5 is wrapped with hemp rope to prevent the grape vines 9 from being damaged by hard collisions with the frame 5 during vibration.

[0023] The vibrator 6 has a vibration frequency of 300-1000 Hz and an amplitude of 0.01-0.2 mm. This vibration frequency range, combined with the amplitude, can effectively prevent fruit berries from colliding with each other and can also create variable air channels between the fruit bunches to evaporate residual moisture in the bunches, preventing fruit berries from rotting and spoiling due to poor ventilation and residual moisture. It can also reduce the shading between fruit berries, allowing the fruit berries inside the bunch to receive more sunlight and improving the taste of the fruit berries inside. Due to the slight shaking of the fruit stalk, the stalk constantly changes position, and under the influence of sunlight and gravity, the fruit stalk is not entangled, making the distance between the fruit berries loose and providing more growing space for the fruit berries, thus improving the situation where the fruit berries inside the bunch are squeezed and deformed due to insufficient growing space.

[0024] A control method for grape cultivation using a special trellis in a greenhouse includes the use of a vibrator 6. The vibrator 6 is used intermittently 2-4 days after each watering, following the first swelling stage of the grapevines. Each vibration session lasts 6-12 minutes, with a shutdown time of 10-30 minutes. This intermittent vibration prevents injury to the grapevines and berries. The vibrator 6 is repeated 4-5 times daily. During this period, the grapevines are in a rapid growth phase, and the cells within the berries have undergone acute water absorption, resulting in balanced turgor pressure and relatively balanced physiological activity and division. The cells are plump, the skin is strong, and the fruit is firmly connected to the pedicel. Slight collisions between berries during the vibration process will not cause skin breakage or berry drop. The optimal time for intermittent operation is between 6-8 AM, when cell conditions are stable, transpiration rates are low, and wilting is prevented, effectively preventing grape berry drop.

[0025] A method for controlling the growth of grapevines in a greenhouse using a special trellis system includes: intermittently turning on the vibrator 6 after each watering as a vibration cycle; and on the second or third day after completing one vibration cycle, spraying the entire grapevine vine 9 with a growth-promoting compound agent. The growth-promoting compound agent comprises 1 volume part of a 700-800 times diluted solution of Wofengsu, 0.3-0.8 volume parts of a 400-600 times diluted solution of brassinolide, and 1.2-2 volume parts of a 30-60 times diluted solution of wood ash. The spraying dosage is 350 ml. The growth-promoting compound drug, with a dosage of 500 ml to 500 ml per vine, works synergistically on the grapevine 9, effectively inducing cell division at the pedicel and stem, which helps elongate the pedicel, increases the gap between grape berries, and provides more growth space for the internally compressed berries, resulting in a fuller grape bunch. On the other hand, the growth-promoting compound drug prevents the occurrence of tiny wounds at the pedicel and stem after vibration of the vibrator 6, promotes rapid wound healing, reduces the invasion of pathogens, and further prevents grape berries from falling off during the growth process after vibration.

[0026] The optimal time to spray growth-promoting compound drugs is 1-2 hours before sunset in the afternoon.

[0027] The preferred ratio of the growth-promoting compound drug is 1 part by volume of 700 times diluted Wofengsu solution, 0.5 parts by volume of 600 times diluted brassinolide solution, and 1.5 parts by volume of 40 times diluted wood ash solution.

[0028] Furthermore, the preparation process of the diluted wood ash solution is as follows: take 1 volume part of wood ash and 30-60 volume parts of water, mix and stir, then stir every 5-8 hours. After 30-48 hours of mixing, filter the residue and take the clear liquid for use, to ensure that the effective substances in the wood ash are fully dissolved in the water.

[0029] The present invention will be further described below with reference to specific embodiments and comparative examples:

[0030] In Example 1, the vibration frequency of vibrator 6 is 300 Hz, and the amplitude is 0.2 mm. The method of using vibrator 6 is as follows: after the first swelling stage of the grapevines, vibrator 6 is intermittently turned on 2-4 days after each watering. The vibrator 6 is turned on at 6:00 AM, with an on time of 10 minutes and a off time of 20 minutes, repeated 4 times daily. On the 5th day after watering, a growth-promoting compound is sprayed onto the grapevines 9. The growth-promoting compound consists of 1 volume part of a 700-fold diluted solution of Wofengsu, 0.5 volume parts of a 600-fold diluted solution of brassinolide, and 1.5 volume parts of a 40-fold diluted solution of wood ash. The preferred spraying time is 1 hour before sunset in the afternoon.

[0031] In Example 2, the vibration frequency of vibrator 6 was 800 Hz and the amplitude was 0.05 mm. The vibrator 6 was used as follows: after the first swelling stage of the grapevines, vibrator 6 was intermittently turned on daily for 2-4 days after each watering. The vibrator 6 was turned on at 7:00 AM for 12 minutes and turned off for 30 minutes, repeated 5 times daily. On the 5th day after watering, a growth-promoting compound was sprayed onto the grapevines 9. The composition and spraying time of the growth-promoting compound were the same as in Example 1.

[0032] Comparative Example 1: The vibration frequency of vibrator 6 was 60 Hz, and the amplitude was 1 mm. The method of using vibrator 6 was as follows: after the first swelling stage of the grapes, vibrator 6 was intermittently turned on 2 days before each watering. The vibrator 6 was turned on at 3 PM, with an on time of 10 minutes and a off time of 20 minutes, repeated 4 times daily. No growth-promoting compound drugs were sprayed.

[0033] Comparative Example 2: The vibration frequency of vibrator 6 was 300 Hz, and the amplitude was 0.2 mm. The method of using vibrator 6 was as follows: after the first swelling stage of the grapes, vibrator 6 was turned on intermittently on the same day and the following day after each watering. The vibrator 6 was turned on at 3 PM, with a duration of 10 minutes and a shutdown time of 20 minutes, repeated 4 times daily. No growth-promoting compound pesticides were applied.

[0034] In Examples 1, 2, Comparative Examples 1, and 2, the vibrator 6 was used on healthy grapevines 9 grown in the same greenhouse under unified management. All selected grapevines 9 produced fruit normally. At harvest time, three bunches of grapes were randomly picked from each vine 9 for statistical analysis. In Examples 1 and 2, the grape bunches showed uniform coloring, no internal rot, and plump, round berries. The taste of the berries inside and outside the bunches was almost indistinguishable, and there was no berry drop. In Comparative Example 1, there was significant berry drop before harvest, with less cracking; the main symptom was berry drop. In Comparative Example 2, there was berry drop before harvest, and cracked berries were present on the bunches and among the dropped berries. During harvest, berry drop was significant. In Comparative Examples 1 and 2, the grape bunches showed varying degrees of cracking and berry drop.

[0035] Therefore, the greenhouse-specific grape cultivation rack and control method of the present invention can effectively improve the ventilation and light transmission inside the grape bunches, without causing the grape berries to crack or fall off, making the taste of the berries more uniform and consistent, and improving the overall quality of the grape bunches.
