In the cultivation process of Chinese medicinal materials, there are often hazards such as cockroaches, earthworms, golden worms, cockroaches, etc., which directly affect the survival of the seedlings of the Chinese medicinal materials and the development of the plants, so that the quality of the medicinal materials is deteriorated and the yield is reduced. Therefore, effective prevention and control of underground pests in the drug field is the key to ensuring robust plant growth and increasing yield. According to production experience, the following comprehensive methods must be adopted to control underground pests:
1. Deep ploughing in winter: In the winter, the soil is deeply cultivated by 35 cm, and with the cultivation of worms, the ploughing can destroy the survival of the pests and the wintering environment, and reduce the density of the next year.
2, manure treatment: unfertilized farmyard manure is a good place for underground pests to lay eggs. Therefore, cultivated medicinal plants should be applied to fully decomposed farmyard manure. At the time of application, 5% of carbaryl 500 g per acre was used for the harmless treatment of the medicament, and the effect was good.
3, clean up the pastoral: weeds are the main place for underground pests to lay eggs and conceal, and also a bridge for the migration of larvae to the drug field. Therefore, after harvesting the head lice crops, timely weeding the weeds in the field can reduce the number of wintering larvae and pupa; at the same time, timely shovel the weeds in the field before the emergence of the crops or the larvae of the 1-2 larvae in the underground pests. Early food intake of larvae can also eliminate some larvae and eggs. Weeds are buried or transported out of the field, and fertilizer is used to eliminate spawning parasites.
4, pesticide dressing: with 3% carbofuran granules per acre with 1000 grams of seed dressing, can control cockroaches, cockroaches, yellow ants, ground tigers and golden worms and other underground pests.
5. Root filling: When the seedlings are pesty, if the seedlings are found and the larvae are found in the soil, 90% crystal trichlorfon 800 times solution, 50% diazinon emulsifiable concentrate 500 times solution, 2.5% enemy kill 6000 times solution, Quickly kill 400 times of butyl or 50% of phoxim emulsifiable concentrate 500 times, optionally fill one of the above liquids, fill once every 8-10 days, continuously 2-3 times, killing tigers and cockroaches And underground pests such as golden worms.
6. Spreading poisonous soil: 5% of butyl p-butyl phosphate per acre is 2.5-3 kg, can be applied by ditch and acupoints, and the efficacy period is up to 60-90 days; or 50% phoxim emulsifiable concentrate per acre is 500 g. Mix fine sand or fine soil 25-30 kg, spread the ditch next to the drug root and sprinkle it into the soil, and then cover the soil; or combine the shovel and cultivating the soil to control a variety of underground pests.
7. Irrigation and disinfestation: In areas with good water source conditions, after the occurrence of the ground tiger, timely irrigation, the pest control effect is good.
8. Manual catching: Every morning, the field will open the topsoil around the newly damaged medicine seedlings or the residual stems and leaves of the damaged stems, and catch the pests and concentrate them.
9. Inducing adult worms: The effective methods for trapping adult worms are usually: (1) using the phototaxis of scarabs, terrapins, and cockroaches, and placing some black light lamps to trap them during the adult germination period. (2) Mix 1000g of wheat bran (bean cake) with 100g of trichlorfon with warm water after adding saute, add 100g of brown sugar, suffocate for 3-5 minutes, make bait, divide bait into small in the evening. Distributed between the sloping lines of the transplanted medicine field, can trap the tigers, cockroaches and other adults, and collect the pests in the early morning. It can also be used with 100% of 20% methomyl emulsifiable concentrate, diluted with 1000g of water, sprayed in 100kg of fresh grass or chopped vegetables (about 16cm long), mixed into bait, stacked in the field in the evening, every A small pile of 30-40 cm in diameter and 15 cm in height is piled up at a certain distance, and 25 kg of poison bait is used to trap the tiger, or a fresh walnut branch of about 1 m is used to soak the 50-fold diluted omethoate solution, 10 After the hour, take it out and insert it into the field of the medicinal material in the evening, 25-40 per acre. The effect of trapping the chafer is good.
10, ground application: In the evening, use a 16-type agricultural sprayer, according to the standard of 2.5% of the enemy to kill 8 ml of water in a bucket of water, with 2000 times the solution, spray the ground. This pest control technology can be used to control various underground pest pests of various medicinal materials.
11. Plant application: When the seedlings of the medicinal plants have holes, nicks and other symptoms, use 90% trichlorfon 800-1000 times solution, 50% octyl sulfate emulsifiable oil 1000-1500 times solution, 50% diazine emulsifiable concentrate 1000- 1500 times liquid, 20% anti-feeding amine emulsion 500 times liquid, the above agents may be sprayed or alternately used. Adults are sprayed 2-3 times in the evening, and once every 7-10 days.

TOF (Time of Flight) ranging sensor is a type of sensor that measures distance by calculating the time it takes for a light signal to travel from the sensor to the target object and back. It uses laser or infrared light to emit a signal and measures the time it takes for the signal to return to the sensor. By knowing the speed of light, the sensor can accurately calculate the distance between itself and the target object.
TOF ranging sensors are commonly used in various applications such as robotics, autonomous vehicles, industrial automation, and augmented reality. They provide accurate distance measurements and can be used for object detection, collision avoidance, gesture recognition, and mapping.
Compared to other distance measurement technologies like ultrasonic sensors or infrared proximity sensors, TOF ranging sensors offer several advantages. They provide higher accuracy, faster response times, and can work in various lighting conditions. They are also capable of measuring longer distances and can be used for both indoor and outdoor applications.
Overall, TOF ranging sensors are a versatile and reliable technology for measuring distances and are widely used in many industries for a range of applications.
