Organic tea pest control technology

With China's accession to the WTO and the needs of the development of the market economy, the promotion of new technologies for organic tea plant protection and the improvement of tea quality and safety have become an urgent task for plant protection technicians. The relevant technical points are described below. 1. Use natural enemies to control pests 1.1 Create a good environment for natural enemies. Around the tea plantation, pine, brown, buckwheat and other protective forests or street trees can be planted to improve the tea plantation's ecological environment, maintain the balance of the tea garden ecosystem and the diversity of biological communities, and create good habitats and breeding sites for natural enemies. 1.2 More pests were raised in tea gardens to control the pests. Chickens can eat a large number of pests in the forestry tea gardens, thereby reducing the amount of pests; chickens can also feed on weeds, grab planed loose soil, chicken manure can be fertilizer garden, to remove weeds, promote soil microbial activity and fertilization The land has a certain role. 2. Agricultural measures for controlling pests 2.1 Selection of disease-resistant pests: The selected varieties are Fuding Dabai, Longjing 43, Fuyun 6, etc. These varieties are more resistant to aphid, tea scab, black locust whitefly and tea caterpillar. 2.2 Proper and close planting: Organic tea gardens are generally chosen to be built in high mountain or semi-mountainous areas with good natural conditions, lush vegetation and suitable climate. Tea planting spacing 1.5 meters, spacing 0.3-0.4 meters, planting 2 to 3 plants per hole, single planting, favorable tea garden ventilation. 2.3 Application of Organic Fertilizer: 100 kg of compound fertilizer per acre before spring tea, combined with deep turning in autumn and winter, applying 200 kg of organic fertilizer per acre, such as cake, manure, and manure, to cultivate fertility, enhance tree vigor and improve tea tree itself. The ability to resist pests and diseases. 2.4 Intensive cultivation: Diligent weed removal can reduce pests and wintering habitats, and can effectively control pest reproduction and harm. A shallow ploughing and weeding is performed prior to spring tea extraction to remove overwintering weeds. After the end of the rainy season in June, weeding and weeding were conducted once, and weeding and weeding were conducted once in August. In October, weeding, cleaning, and sealing the park. 2.5 Picking at the right time: It is required to pick several times in batches in the picking season to reduce the harm of various pests such as aphids, small green leafhoppers and tea orange borers. 3. Physical measures There are mainly three physical measures for controlling pests: The first is the use of insect sex pheromones and mutual maturation to trap and intervene normal mating behaviors of insects, such as trapping and killing male moths such as tea caterpillars and tea silkworms with sex attractants. The second is to use frequency-vibration insecticide traps to kill pests. The third is the use of pest odor characteristics, using sweet and sour venom to trap leaf roller moth adults. 4. Other pest control measures 4.1 The use of pesticides such as celangulin, a plant-derived crude drug, to control lepidopteran pests and small green leafhoppers, etc., has good control effect. 4.2 When the park is closed in winter, pesticides such as lime sulfur can be used to control leafhoppers, leafhoppers and diseases. 4.3 Development and use of biological preparations to prevent and control pests, such as the use of Beauveria bassiana preparations to prevent and control tea Lilium and small green leafhoppers, Bacillus thuringiensis preparations against tea caterpillars, tea-footworm, black-spotted moth and other pests are better.

Hospital Bed

Hospital Bed, also known as hospital bed, Hospital Equipment, Nursing Bed, etc., is a hospital bed used by patients when they are hospitalized in the hospital.

According to the function, it can be divided into electric medical beds and manual medical beds. Among them, electric medical beds can be divided into five-function electric medical beds and three-function electric medical beds. Manual medical beds can be divided into double-shake medical beds and single-shake medical beds. Medical beds, flat medical beds.

According to whether it can be moved, it can be divided into a wheeled medical bed and a right-angle medical bed. Among them, electric medical beds are generally movable with wheels.

In addition, there are other special function beds, such as: ultra-low three-function electric bed, Hospital Bed For Home, hospital bed with bedpan, scald rollover bed, rescue bed, mother-child bed, crib, child bed, ICU monitoring bed, examination bed, etc.
