Since ancient times our country has had a habit of drinking tea. The fragrance of tea is refreshing and thirst quenches the thirst and is popular with people. However, with the improvement of living standards, people not only demand that they can drink tea, but also hope that they can drink green, unpolluted tea. This is what we usually do. Said pollution-free tea. Pollution-free tea refers to production under a specific production and operation procedure in a pollution-free production environment. After inspection, pesticide residues, heavy metals and harmful microorganisms meet the requirements of GB2762 and GB2763 tea hygiene standards formulated in 2005. This type of tea has a normal appearance and inherent color, aroma, and taste. It must not be mixed with exotic plant leaves, non-non-tea materials, no odor, and no mildew. Here's a brief introduction to pest control technology for pollution-free tea
One, to take (scissors) control insects. Timely picking, reasonable pruning, Taiwan wolfberry can improve the ventilation and light conditions of the tea garden, suppress the occurrence of hibernation or hibernation close conditions of black locust whitefly, scale insects and so on. It can reduce the risk of many dangerous pests such as aphids, small green leafhoppers, and elephant armor. For insects, shoots must be reclaimed and harvested. In the summer and autumn seasons, as many leaves as possible should be picked. There are many pests in the fall, which can extend the picking and delay the closure of the park.
Second, ploughing pests. Usually in summer and autumn, it is suitable for turning 1~2 times. Severe plots of the Lizard's Weevil have deeper turn before the spring tea is mined, which can significantly reduce the occurrence of pests. Combined application of organic manure in winter for deep cultivating soil, exposing earthworms and elephant larvae to the ground, causing them to die due to environmental discomfort or predation by natural enemies. When the soil is properly repressed, the insects will die mechanically or they will not be able to emerge in the following year.
Third, to fertilizer resistance. The application of organic nitrogen fertilizer can increase the tea tree resistance to tea orange borer; the application of lime is not conducive to the survival of thrips and leafhoppers; phosphate rock extract as the top dressing can kill red spider. Replanting basal fertiliser, reasonably applying spring fertilizer, summer fertilizer, autumn fertilizer, mainly organic fertilizer, supplemented by chemical fertilizer, balanced application of nitrogen, phosphorus and potassium, and paying attention to drainage and irrigation and drought prevention, can significantly improve the resistance to insects.
Fourth, "species" pest control. That is, proper planting methods are used to reduce the occurrence of pests and diseases. For example, when opening a new garden, use seedling-free seedlings, try to adopt clustered or strip planting methods, avoid over-close planting, and create a good tea garden ecological environment; a reasonable intercropping of tea gardens to prevent large-scale single planting in order to maintain rich natural vegetation , reduce the incidence of major pests. However, in the serious tea plantations in the small green leafhoppers, tea plantations should not be interplanted with peanuts and legumes. Spodoptera litura areas should not be interspersed with sweet potatoes.
Fifth, pest control. Protection of natural enemies, such as pruning, branches and leaves underneath Taiwan, can be piled up near the tea plantation to facilitate the return of natural enemies to the tea gardens; artificially removed egg pieces, insect packs, and protective bursa have many natural enemies and are surrounded by water. In the altar and suizhong, to be treated after parasitoids and parasitic fly flies out; to collect spiders with grass to control insect pests in tea gardens; to attract insects to feed tea garden pests; to protect crickets and frogs and to prevent chickens and ducks from tea Silkworms and so on. It can artificially multiply and release natural enemies, such as the tea-footed tick beetle, the Trichogramma beetle, the grass beetle, the ladybug ladybug, the farmland bee bee, and the predator. It can also introduce natural enemies and develop and use biological agents to control pests. For example, Bacillus thuringiensis preparations and virus preparations control Lepidoptera pests such as Chazie, Tea caterpillar, Black-sucking moth, Beauveria bassiana, Laodelphus repens and Chaenomeles falciparum, and fungal preparations to control Blackthorn mealybugs. In addition, pathogenic microorganisms can be extensively propagated and processed into biological pesticides for use.
Six, to catch (entice) insecticide. Such as catching large scales, adults can also capture their old larvae. In the early spring, the eggs of tea caterpillars were collected, and the cluster larvae of the tea caterpillars and moths were killed, and the insects of the leafhoppers, codling moths and insects were pinched, and the adults were lighted.
