Description

Technical Field

[0001] The invention belongs to the field of garden pest control, and in particular relates to a method for controlling rose pests by using a spectrum period. Background Art

[0002] Garden roses (Rosa spp.) are often invaded by various pests during the planting process, which seriously affects the growth and ornamental effect of the plants. Spider mites suck the juice from the leaves, causing grayish-white spots to appear on the leaves, causing them to dry up and fall off early. When severely infected, the entire plant is on the verge of death; aphids harm tender shoots, young leaves and flower buds, causing bud atrophy, leaf curling, abnormal flower color or failure to bloom after the buds bloom, and the secretion of nectar causes sooty mold, further reducing the ornamental value of roses. Thrips suck the petals and young leaves, causing the leaves to shrink and become deformed, and brown or silvery-white spots to appear on the surface of the petals, significantly damaging the color and quality of the flowers. In addition, leaf-feeding pests such as the larvae of the spiny moth and the adult beetle are more harmful in summer and autumn. They are highly destructive to rose leaves and flower buds and can quickly eat a large number of leaves, resulting in obstructed photosynthesis and deterioration of the plant's health.

[0003] At present, the main means of prevention and control of rose diseases and pests are chemical agents. Although these agents are fast-acting, long-term use will lead to increased resistance of pests and a gradual weakening of the prevention and control effect. At the same time, excessive application may also cause harm to the environment and non-target organisms.

[0004] Biological control is a method of using one organism to fight another organism. It is limited by environmental conditions and difficult to implement on a large scale.

[0005] The limitations of these control methods highlight the need to find more efficient and environmentally friendly technologies.

[0006] Studies have shown that specific light waves can interfere with the behavior of pests and inhibit their feeding and reproduction. At the same time, specific sound waves and vibrations can inhibit the wing flapping and flight behavior of some pests, interfere with mating and egg laying, and affect the development and reproduction of nymphs. However, this control technology currently lacks an economical and practical standardized application method.

[0007] The role of vibration and combination

[0008] If light waves can be used to control rose pests and diseases, it will not only reduce the use of chemical agents and alleviate the problem of pest resistance, but also play an important role in environmentally friendly garden management. Summary of the invention

[0009] The purpose of the present invention is to provide a method for controlling rose pests using a spectral period, so as to achieve targeted control of common pests on rose plants and reduce the damage to the environment and ecology caused by traditional pest control methods.

[0010] To achieve the above purpose, the technical solution of the present invention is as follows:

[0011] A method for controlling rose pests by using a spectral cycle, wherein blue LED lamps and purple LED lamps are used to illuminate rose plants at night from March to May each year, the blue LED light accounts for 20-80%, the purple LED light accounts for 20-80%, the air humidity is maintained at ≥80% during the irradiation process, the irradiation time is 4-6 hours, and a low-frequency oscillator with a frequency range of 100-500 Hz is used to oscillate the roses;

[0012] From June to November every year, sulfur plasma lamps illuminate rose plants for 4 to 6 hours at night, and high-frequency oscillators with a frequency range of 20 to 50 kHz are used to oscillate the roses:

[0013] A phosphor coating is coated on the surface of the sulfur plasma lamp. The components of the phosphor coating include, by weight percentage: 10-20% of calcium aluminum silicon nitride doped europium phosphor powder, 17-40% of silicone resin, 45-70% of dimethylformamide, 1-2% of polyethylene glycol, 0.5-2% of 2-hydroxy-2-methylpropiophenone, 0.5-1% of tetrabutylammonium hydroxide, and 0.1-0.5% of polydimethylsiloxane.

[0014] Preferably, when different types of pests break out, the spectrum adjustment and irradiation time are shown in the following table:

[0015]

[0016] Preferably, the wavelength center of the blue light LED lamp is 460-480nm, the power density is 3-5W / m, the light emitting angle is 100-120°, and the brightness is 150-200lm / m.

[0017] Preferably, the wavelength center of the purple LED lamp is 400-420nm, the power density is 3-10W / m, the light emitting angle is 90-100°, and the brightness is 100-150lm / m.

[0018] Preferably, the high-frequency oscillator is a piezoelectric ceramic oscillator with an output power of 0.5 to 20 W, which is installed at 2 / 3 to 3 / 4 of the height of the rose plant with an installation interval of 4 to 8 m.

[0019] Preferably, the low-frequency oscillator is a mechanical vibrator with an output power of 0.5 to 20 W, which is installed underground under the rose plant at a distance of 5 to 10 cm from the ground, with an installation interval of 2 to 4 m.

[0020] Preferably, the sulfur plasma lamps are installed at a height of 2 to 4 meters from the rose plants, with an installation interval of 5 to 10 meters.

[0021] Preferably, the coating method of the phosphorescent coating on the surface of the sulfur plasma lamp is:

[0022] 1) Stir siloxane resin, dimethylformamide and mixed 2-hydroxy-2-methylpropiophenone evenly, then add dispersant polyethylene glycol and catalyst tetrabutylammonium hydroxide, stir until completely dissolved, then ultrasonically treat the mixed solution for 5 to 10 minutes, then add calcium aluminum silicon nitride doped europium phosphor powder, stir until the calcium aluminum silicon nitride doped europium phosphor powder is evenly dispersed, then add leveling agent, stir evenly, and finally filter the coating through a 150-200 mesh filter, let it stand for more than 30 minutes, and obtain a phosphor coating;

[0023] 2) In a dust-free environment, use anhydrous ethanol to clean the surface of the sulfur plasma lamp to ensure that there is no dust and grease, put the sulfur plasma lamp in a drying oven, preheat it to 50-60° C. for more than 30 minutes, and evenly spray the phosphor powder coating on the surface of the sulfur plasma lamp, and the coating thickness is controlled to be 30-50 μm;

[0024] 3) Dry naturally at room temperature, use ultraviolet light source with wavelength of 365-405nm for light curing, the light curing time is 30-120 seconds, and the ultraviolet light intensity is 800-1200mW / cm 2 Then put it into an oven, heat it to 80-100°C, keep it for 2-3 hours, complete the light curing, and obtain the finished sulfur plasma lamp.

[0025] Preferably, the blue LED lamp and the purple LED lamp are installed at the same height as the rose plants.

[0026] Preferably, a sprayer is used to increase the air humidity, and the sprayer is installed at the highest point of the inner wall of the flower bed, with an installation interval of 2 to 4 m.

[0027] Preferably, the air humidity is measured by a light intensity, temperature and humidity sensor, and the light intensity, temperature and humidity sensor is installed at 2 / 3 to 3 / 4 of the height of the rose plant, with an installation interval of 4 to 8 m.

[0028] Among the common diseases and pests of roses, aphids and spider mites can be repelled when exposed to blue light and purple light. This is because aphids and spider mites have lost the system in their bodies that repairs cell damage caused by light. In order to minimize light damage, they develop an avoidance habit when they see blue light and purple light.

[0029] For the prevention and control of whiteflies, thrips and scale insects, a mixture of blue and purple light is used, especially when the air humidity is ≥80%. In order to adapt to the high humidity environment, insects need to balance the water in their bodies, and the interference of blue-purple mixed light on the insect metabolic system aggravates its physiological imbalance, thereby accelerating its death.

[0030] The sulfur plasma lamp uses a microwave drive system, combined with a pulse width modulation module (PWM), to set the output frequency within the range of 300 to 500 Hz, which not only avoids the flicker that can be detected by the human eye, but also interferes with and repels insects. The rear of the sulfur plasma lamp is equipped with a heat dissipation device to improve stability. The surface of the sulfur plasma lamp is sprayed with a phosphorescent coating. Through calcium aluminum silicon nitride doped with europium phosphor powder (Eu2+: CaAlSiN), it can filter non-target stray light (400 to 550nm) and enhance the output of red light (550 to 700nm). The silicone resin and a variety of additives have excellent leveling, adhesion and light conversion efficiency, ensuring the long-term stability of the coating in high temperature and high humidity environments. In addition, the continuous spectrum advantage of the sulfur plasma lamp makes it perform significantly in repelling leaf-eating pests such as the spur moth and the lantern moth, and is particularly suitable for the prevention and control needs of leaf-eating pests during the high incidence period from June to November.

[0031] The central wavelength of blue LED lamps is 460-480nm, and the central wavelength of purple LED lamps is 400-420nm. By adjusting the proportional power and luminous angle distribution of the two, targeted prevention and control of different pests can be achieved. When installing blue LED lamps and purple LED lamps, the light should be concentrated and evenly covered as much as possible to reduce energy waste.

[0032] The piezoelectric ceramic oscillator can accurately generate high-frequency sound waves of 20 to 50 kHz, which have a strong effect in repelling leaf-eating pests. In addition, the sound waves of 20 to 40 kHz cannot be recognized by humans. While being able to effectively repel insects, it does not interfere with humans.

[0033] The mechanical vibrator is placed 5 to 10 cm below the ground under the rose plant. The vibrator generates low-frequency vibrations of 100 to 500 Hz in the soil near the plant roots, which can be transmitted well in the soil, affecting root pests and also transmitting to the surface plants. At the same time, it also avoids the interference of vibration waves in the air to people.

[0034] The combination of high and low frequency sound waves can further enhance the effect of repelling pests. High-frequency sound waves of 20 to 50 kHz can inhibit the flapping and flight behavior of whiteflies, interfere with mating and egg-laying; for noctuids, spur moths, and tiger moths, they can simulate the signals of natural enemies such as bats to trigger strong avoidance behavior, reduce adult mating and larval feeding rates. Low-frequency vibrations of 100 to 500 Hz can disrupt aphids' secretion of honeydew and group communication; spider mites are disturbed by low-frequency vibrations, and their stomata are closed and their activities are restricted; the feeding and movement behavior of thrips will also be significantly reduced; and low-frequency sound waves can induce scale insects to undergo internal mechanical resonance, affecting the development and reproduction of nymphs. For beetles, low-frequency sound waves can disrupt the soil activities of their larvae and grubs, while high-frequency sound waves affect the flight ability of adults.

[0035] Combined with the information from light intensity, temperature and humidity sensors, intelligent algorithms are used to identify and analyze the types of pests and their probability of occurrence, and dynamically adjust the on / off time of lamps, the ratio of spectrum and sound waves, and the working time. In addition, the system also takes into account the function of garden landscape lighting. During the non-pest high-incidence period, blue and purple LED strips can be used as night landscape light sources, and sulfur plasma lamps provide high-efficiency viewing lighting effects. The purple light strip lighting time is controlled during the inactive period of tourists to reduce discomfort to the human eye.

[0036] Compared with traditional chemical control methods, this system effectively reduces the use of pesticides, avoids environmental pollution and pest resistance problems, and the blue-violet light is continuously irradiated on the back of the leaves, which avoids the situation where traditional pesticide spraying is difficult to act on the back of the leaves. The traditional use of light to control pests mainly focuses on light trapping, but insect traps have a certain degree of mistaken killing effect on natural enemy insects and also have a certain negative effect on ecological diversity. The use of insect repellent spectrum to repel pests can accurately avoid target pests, while having less impact on natural enemy pests. For example, 460-480nm blue light has a strong repellent effect on aphids, but has little impact on their natural enemy ladybugs, avoiding damage to the ecology and enhancing the effect of the ecosystem itself in preventing and controlling aphids.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] The present invention achieves effective control of rose diseases and pests through scientific spectrum selection, and can accurately control target pests. Compared with traditional chemical control, it effectively reduces the use of pesticides, avoids environmental pollution and pest resistance problems, and the spectrum irradiation can directly reach the back of the leaves, avoiding the situation where traditional pesticide spraying is difficult to act on the back of the leaves. Compared with the traditional method of using light to lure and kill pests, it avoids the accidental killing of other beneficial pests, avoids damage to the ecology, and enhances the effect of the ecosystem itself in controlling aphids.

[0039] The rose pest control system of the present invention achieves precision and efficiency in pest control, while meeting the needs of garden landscape lighting, reducing garden maintenance costs, showing great application potential in the field of pest management, and meeting the goal of sustainable development of ecological gardens. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 1 This is a comparison chart of the pest control effects of Example 1 of the present invention under different conditions. DETAILED DESCRIPTION

[0041] The present invention will be further described below in conjunction with the embodiments and drawings.

[0042] Example 1: Comparative experiment on insect repellent conditions. Experimental setting: The experiment was conducted in a black light-proof box with a length and width of 1 m and a height of 0.5 m. Two comparison groups and six experimental groups with different lighting and vibration matching were set up. Lights with different wavelengths and oscillators with different vibration frequencies were set up in the upper right corner of the box. Four pots of roses with the same size and height were placed in each box, and the same pests were placed in each pot. The setting is shown in Table 1.

[0043] Table 1

[0044]

[0045] The number of pests was counted after the light and oscillator were working for one day. Figure 1 .

[0046] As can be seen from the figure,

[0047] In control group 1, where no pest control treatment was performed, the number of pests was the highest, indicating that the wavelength and oscillation of light can effectively suppress the number of pests.

[0048] In control group 2, (sulfur plasma lamp without phosphorus coating + 30kHz oscillation) has a certain control effect on noctuid armyworms, cutworms, tiger moths and scarab beetles, but the control effect on noctuid armyworms, cutworms and tiger moths is obviously much weaker than that of experimental groups 3 and 6.

[0049] Experimental group 1 (470nm blue light + 300Hz oscillation) performed best in reducing aphids and had certain effects on whiteflies and scale insects.

[0050] Experimental group 2 (410nm purple light + 300Hz oscillation) performed best in reducing spider mites, thrips, and scale insects, and had certain effects on whiteflies and scale insects.

[0051] Experimental group 3 (phosphorus-coated sulfur plasma lamp + 300 Hz oscillation) had a certain effect on controlling noctuid moths, cutworms, tiger moths and scarab beetles, but the effect was not as good as that of experimental group 5.

[0052] Experimental group 4 (470nm blue light + 30kHz oscillation) has a certain effect on aphids and whiteflies, but not as good as experimental group 1. It also has a certain effect on the control of noctuids, caterpillars, tiger moths and beetles, but the effect is not as good as experimental group 5.

[0053] Experimental group 5 (410 violet light + 30kHz oscillation) had the most significant control effect on whiteflies.

[0054] Experimental group 6 (phosphorus-coated sulfur plasma lamp + 30kHz oscillation) had an outstanding effect in reducing noctuid moths, cutworms, tiger moths and scarab beetles.

[0055] Example 2: Garden application experiment

[0056] In order to avoid the influence of terrain factors on the test results, five 5m×2m sample plots were set up in the rose green belt with consistent terrain conditions in the study area. The sample plot settings are shown in Table 1. White sticky insect boards of size 50cm×50cm were hung at 2m and 5m of the sample plots. Pest counts and replacements were carried out on the sticky insect boards every February. Ten leaves of the same size were randomly selected from the sample plots every February to count the pests on the front and back. The experimental results are shown in Tables 1 and 2.

[0057] In the control group 1, no pest control measures were taken and the number of pests remained at a high level.

[0058] In the control group 2, the pest control measure was to spray 0.2% cypermethrin once a week; although the control effect was more obvious in the early stage, it gradually weakened with the passage of time, and there was a risk of environmental pollution and pest resistance.

[0059] In the control group 3, the pest control measure was to use incandescent insect trapping equipment, irradiating for 8 hours every night; although it had a certain inhibitory effect on some pest species, the overall effect was limited.

[0060] In the control group 4, the pest control measures are as follows: from March to May each year, blue LED lights and purple LED lights are used to irradiate the rose plants at night, with the blue LED light intensity of 50% and the purple LED light intensity of 50%. During the irradiation process, the air humidity is maintained at ≥80%, and the irradiation time is 4 to 6 hours; from June to November each year, sulfur plasma lamps are used to irradiate the rose plants at night for 4 to 6 hours; the number of piercing-sucking pests (such as aphids and whiteflies) and leaf-feeding pests (such as brown-edged green moth and noctuid armyworm) is significantly reduced, especially in July-December, the number of piercing-sucking pests is reduced by more than 70%, and the number of leaf-feeding pests is reduced by more than 60%.

[0061] In the experimental group, from March to May each year, blue LED lamps and purple LED lamps were used to irradiate rose plants at night, with the blue LED light accounting for 20-80%, and the purple LED light accounting for 20-80%. During the irradiation process, the air humidity was maintained at ≥80%, the irradiation time was 4-6 hours, and a low-frequency oscillator with a frequency range of 100-500Hz was used to oscillate the rose; from June to November each year, a sulfur plasma lamp with a phosphorescent coating was used to irradiate the rose plants at night for 4-6 hours, and a high-frequency oscillator with a frequency range of 20-50kHz was used to oscillate the rose: the comprehensive insect prevention effect is more prominent when pests are controlled according to the means described in the present invention, which not only further reduces the number of pests, but also can control the number of some pest species (such as brown-edged green caterpillars and noctuids) at extremely low levels, proving the synergistic effect of spectral interference and vibration on pest control with high efficiency and accuracy.

[0062] In summary, the present invention, which utilizes the combination of spectral irradiation and vibration, has obvious sustainability and eco-friendliness and is worthy of further promotion and application.
