[0093]

[0094] The application also discloses a green rose thrips prevention and control system based on a multi-modal physical stress rose thrips green prevention and control method, which comprises a spectrum interference system, a ground surface reflection system and a stress incubation cabin.

[0095] Referring to Figure 1 , the spectrum interference system comprises LED light sources 20 comprising main light sources and auxiliary light sources, which are installed in an array at intervals between rose lands.

[0096] The ground surface reflection system comprises a reflection film frame 21 which is installed obliquely towards a rose plant, and the reflection film frame 21 is used for laying a reflection film.

[0097] Referring to Figures 2-6 , the stress incubation cabin comprises a cabin body 1, a fresh flower bearing module, an environmental stress system, a negative pressure collection system and a sunshade mechanism.

[0098] The closed cabin body 1 is made of transparent material, and a silicone curtain is used for the open end face, which not only ensures good sealing to maintain the stability of the internal environment, but also provides initial heat energy for system operation by using the natural light outside, and realizes energy-saving green operation.

[0099] The prevention and control process comprises two stages of “low-temperature and high-humidity incubation” and “high-temperature and low-humidity driving” which are performed in cycles. In the driving stage, the environmental stress system creates an environment that forces the thrips adults to leave the flowers, and combines sound waves and yellow light for induction, so that the adults are captured and inactivated by the negative pressure collection system, and the sunshade mechanism is unfolded intermittently or when cooling is needed, to assist in adjusting the temperature in the cabin.

[0100] The fresh flower bearing module is arranged at the bottom of the cabin body 1 and is used for placing fresh flowers.

[0101] Referring to Figures 2-4The fresh flower carrying module comprises a bed plate 5 and a bed layer 6, the bed layer 6 is installed above the bed plate 5 through a plurality of evenly distributed elastic members 7, the elastic members 7 are formed into an elastic suspension structure by springs or silica gel columns, so that the bed layer 6 becomes an elastically vibrating platform, a vibrator 8 is arranged at the bottom of the bed layer 6, in the high-temperature driving stage, the vibrator 8 is started to generate low-frequency micro-vibration, the vibration is amplified by the elastic members 7 and uniformly transmitted to the fresh flowers on the whole bed layer 6, the vibration simulating the natural environment can effectively disturb the thrips hiding in the deep part of the flowers, destroy the adhesion state of the thrips, force the thrips to separate from the flowers and enter the air, greatly enhance the subsequent airflow and light-induced driving effect, and overcome the defects of dead angles existing in the traditional static treatment mode.

[0102] The negative pressure collection system comprises an air inlet 2 arranged at one side of the cabin body 1 and an air outlet 3 arranged at the other side, a grid structure is arranged at the air inlet 2, the grid structure at the air inlet 2 can prevent large sundries from being sucked in, and a negative pressure fan 4 is installed at the air outlet 3 and used for forming a directional airflow in the cabin body 1, the negative pressure generated by the negative pressure fan 4 can suck away the thrips adults guided to the position of the air outlet 3 and prevent the thrips adults from escaping.

[0103] The negative pressure collection system further comprises an inactivation device and a collection tank 14.

[0104] The inactivation device is a high-voltage insecticidal electric net 13 arranged on the suction passage of the negative pressure fan 4 and used for killing the sucked pests, the adults induced to the air outlet 3 will first pass through the high-voltage insecticidal electric net 13 at high speed and be inactivated instantaneously by high-voltage electric shock, the high temperature caused by the electric shock simultaneously causes the insect bodies to rapidly dehydrate and carbonize and become light and brittle.

[0105] The collection tank 14 is detachably installed below the inactivation device and used for collecting the inactivated pests, the dry insect corpses naturally fall into the collection tank 14, the harmless treatment of the insect bodies is realized, and the risk of secondary pollution is eliminated.

[0106] The environmental stress system is used for regulating and controlling environmental parameters in the cabin body 1, and the environmental parameters include temperature, humidity, carbon dioxide concentration, sound waves and light waves.

[0107] The environmental stress system comprises a temperature and humidity detector, a carbon dioxide concentration detector, a steam generator 9, a carbon dioxide generator 10, a sound wave generator 11 and an optical inducer.

[0108] The temperature and humidity detector and the carbon dioxide concentration detector are arranged in the cabin body 1 and are used for monitoring the environmental parameters in the cabin body 1 in real time, so that the parameters can be accurately and stably set at preset values, the temperature and humidity in the incubation stage are 30±1℃ / 85±3%, and the temperature and humidity in the driving stage are 50-55℃ / 30%.

[0109] Steam generator 9 and carbon dioxide generator 10 are installed inside the chamber 1. Steam generator 9 releases steam through a porous coil (not shown in the attached diagram) extending into the chamber, which can quickly and evenly increase the humidity inside the chamber to the required high humidity level. Carbon dioxide generator 10 releases CO2 directly into the chamber, rapidly increasing the concentration to 800-1200 ppm during the expulsion phase. The high CO2 environment causes thrips to feel suffocated, and in synergy with high temperature and low humidity, it significantly aggravates their discomfort and strengthens their escape behavior.

[0110] The sound generator 11 is installed on the side wall of the cabin 1 with the sound generating end facing the bed 6, and it emits low-frequency sound waves of 170-250Hz. This frequency band of sound waves is an aversion signal to thrips, and can create all-round acoustic stress within their habitat, further driving them away.

[0111] The optical inducer is set at the air outlet 3. The optical inducer is an insect-attracting lamp 12 set at the suction end of the negative pressure fan 4. The light source of the insect-attracting lamp 12 is yellow light with a wavelength of 589nm. After the adult insects are forced to leave the flower, this specific wavelength of yellow light becomes a strong visual guiding beacon, pointing out a unified "exit" direction for the chaotic thrips, causing them to actively gather towards the negative pressure air outlet, thus achieving efficient directional migration.

[0112] A shading mechanism is installed at the top of the cabin 1 to change the light transmittance of the cabin 1. The shading mechanism includes: two side-by-side rollers 15, which are rotatably mounted on the top of the cabin 1 by means of a spring 16; a shading net 17, the fixed end of which is wound onto the rollers 15, and the movable end of which is provided with a support rod 18. A groove 19 is provided at the bottom of the cabin 1, and the support rod 18 can be engaged with the groove 19 to keep the shading net 17 in an unfolded state to shade the cabin 1.

[0113] When cooling is needed, staff can easily unfold the shade net 17 by simply pulling out the support rod 18 and inserting it into the groove 19. The spring 16 makes the retraction operation equally easy. The unfolded shade net 17 can effectively block most of the direct sunlight. Combined with the ventilation of the negative pressure fan 4, it can accelerate the cooling and dehumidification inside the chamber 1, allowing the system to reset quickly and prepare for the processing of the next batch of flowers. This reduces the reliance on external auxiliary cooling equipment and lowers energy consumption.

[0114] During operation, the harvested rose bouquets are neatly placed on the bed 6 of the flower-carrying module, the cabin 1 is closed to ensure a seal, and preparations are made to execute the first prevention and control cycle.

[0115] The steam generator 9 is started to release steam into the cabin through its porous coil, precisely increasing and maintaining the humidity at a high humidity level of 85% ± 3%. At the same time, relying on the solar energy absorbed by the transparent cabin 1 or the auxiliary heating device, the temperature is stabilized at 30 ± 1℃, simulating the suitable environment for thrips egg hatching, prompting the eggs hidden in the receptacle, petals to hatch within 3 hours, and the nymphs to become more active, leaving their original hiding place and thus being exposed to subsequent stress environments.

[0116] After the hatching stage, the system automatically switches to the expulsion mode, and the environmental parameters change dramatically:

[0117] Environmental stress: the steam generator 9 stops working, the negative pressure fan 4 starts working and cooperates with the sunshade mechanism to cool and dehumidify, making the temperature in the cabin rise sharply to 50-55℃, while the humidity drops to about 30%, and the carbon dioxide generator 10 starts working, releasing CO2 into the cabin, making the concentration quickly reach 800-1200ppm. The triple stress environment of high temperature, low humidity, and high CO2 makes the thrips severely dehydrated and suffocated, producing a strong instinct to escape.

[0118] Vibration disturbance: the vibrator 8 set at the bottom of the bed layer 6 is started, producing low-frequency micro-vibration, which is evenly transmitted to the fresh flowers, effectively disturbing and driving away the adults hiding in the deepest part of the flowers, forcing them to fly away from the flowers.

[0119] Sound wave driving: the sound wave generator 11 emits 170-250Hz low-frequency aversive sound waves, creating acoustic stress in the entire cabin, further preventing the adults from falling back and driving them to gather in the air.

[0120] Light-induced orientation: the 589nm yellow light trap 12 set at the air outlet 3 is lit, providing a clear optical guidance signal for the thrips flying in confusion in the air.

[0121] Airflow guidance and capture: the negative pressure fan 4 continues to work, forming a stable directional airflow in the cabin from the air inlet 2 to the air outlet 3. The adults driven by stress and disturbance will instinctively tend to the "more comfortable" airflow outlet direction and be precisely guided to the vicinity of the air outlet 3 by the yellow light.

[0122] The thrips adults induced to the air outlet 3 are first sucked in by the airflow and pass through the high-voltage insecticidal mesh 13, which releases a high-voltage electric shock instantly, inactivating the insect bodies. The inactivated and dried insect bodies naturally fall into the easily pullable collection tank 14 below, achieving harmless treatment and collection, and eliminating the risk of live insect escape or collection device blockage.

[0123] After one "hatching-expulsion" cycle, the next cycle can be entered as needed to ensure thorough elimination of eggs with inconsistent hatching periods.
