Popularization and application of frequency-vibration solar insecticidal lamp in controlling vegetable pests
Today, we will share with you the promotion and application of frequency-vibration solar insecticidal lamps in the prevention and control of vegetable pests. As a new vegetable pest control method, the frequency-vibration solar insecticidal lamp also has some factors that affect the insecticidal effect of the insecticidal lamp. In order to further verify the relevant factors that affect the trapping effect of insecticidal lamps in practical applications, and give full play to the role of frequency-vibration solar insecticidal lamps to trap vegetable pests, we demonstrate while experimenting, which may affect the trapping effect of frequency-vibration solar insecticidal lamps. The main factors (the installation height of the frequency-vibration solar insecticidal lamp, the effect of turning on the lights at different times and at different times), the effects of planting crops and trapping insects, the weather conditions and the trapping effect were tested, observed and achieved certain results. In order to further rationally and effectively promote the use of frequency-vibration solar insecticidal lamps on vegetable crops in the future. The installation height of the frequency-vibration solar insecticidal lamp should be adjusted according to the local facilities and planting conditions. The horticultural field, facilities cultivation, and scaffolding crops can be installed at a height of 100-150 cm. Inconvenient, and the leafy planting area is suitable for lower, the height should be less than 100 cm, otherwise it will affect the insects with small body shape, flying ability and poor jumping ability, such as the diamondback moth. Through the investigation of the trapping of insect pests by the frequency-vibration solar insecticidal lamp, we believe that we should pay attention to the factors such as the use time, installation height and weather requirements of the frequency-vibration solar insecticidal lamp: First, the installation time of the frequency-vibration solar insecticidal lamp and the time required to turn on the light should be from the end of May to the end of October of that year, especially in the June-October of each year, the effect is more prominent, open every day. The light trapping time can trap a large number of main vegetable pests from 19-24 hours in the evening, such as the diamondback moth, the bean wild cockroach, the Spodoptera litura, the beet armyworm, the small tiger, etc., which can effectively reduce the occurrence of the above pests. Base, so it is recommended to turn off the lights after 12:00 midnight. Second, regarding the installation height of the frequency-vibration solar insecticidal lamp, it can be considered in combination with two factors. First, the situation of planting vegetable crops and trapping insect pests in the frequency-controlled solar insecticidal lamp control area, such as leafy crops, the installation height can be appropriately lower, such as below 100cm, which can be used to trap and fly. At the same time, the insects of the nocturnal moths, taking into account small insects and small flying insects, such as the diamondback moth, do not affect the controllable area of ​​each lamp, but in the scaffolding and high-crop crop fields, considering the control area per lamp The frequency-vibration solar insecticidal lamp can be suitably higher, the height is at least 120cm or more, so as to reduce the trapping effect of scaffolding and high-bar crop obstacles; secondly, according to the facilities of the vegetable growing area, it is appropriate to reduce the frequency-vibration solar energy killing. Control of insect light lines. Thirdly, regarding the weather requirements during the trapping of the frequency-vibration solar insecticidal lamp, during the period from May to October each year, there are two points in the light-throwing trap: one is when special weather, such as typhoon, rainstorm or thunderstorm, the second is In the weather with cool weather and wind level 5 or above, it is recommended not to turn on the light to trap and kill. From the base three years of trapping, the weather is cool, the wind is strong, affecting the activities of adults, reducing the trapping effect, and also affecting the service life of the frequency-vibration insecticidal lamp. . Rhodium powder Rh≥99.95% Properties: silver-white metal, extremely hard, wear-resistant, also has considerable ductility Application: It can be used as raw material for electrical instrumentation, chemical industry and manufacture of precision alloys. Rhodium powder is based on the widespread use of ruthenium in the industrial industry. Since rhodium is a rare metal required by the industry, the industry price is slightly higher than that of general non-ferrous metals. Rhodium, one of the rare elements, has various uses. Rhodium can be used to make hydrogenation catalysts, thermocouples, platinum-rhodium alloys, etc. It is also often plated on searchlights and reflectors, and is also used as a polishing agent for gemstones. and electrical contact parts. precious metal XI AN RHINE BIOLOGICAL TECHNOLOGY CO.,LTD , https://www.rhinebioteches.com
