Organic tea plant protection technology

Agricultural measures:
(1) Selection of pest-resistant varieties: The selected varieties are Fuding Dabai, Longjing 43, Fuyun 6, etc.
(2) Proper close planting: Organic tea gardens are generally built in high mountain areas or semi-mountainous areas with good natural conditions, lush vegetation, and favorable 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.
(3) Applying Organic Fertilizer: Apply 100 kg of compound fertilizer per mu before spring tea, combine deep turning in autumn and winter, apply 200 kg of organic fertilizer per mu, such as cake, manure, and manure, to cultivate fertility, enhance vigor, and improve tea tree itself. The ability to resist pests and diseases.
(4) Intensive cultivation: Diligent weed removal can reduce the number of infested wintering sites and effectively control the breeding and harm of pests. A shallow ploughing and weeding is performed prior to spring tea extraction to remove overwintering weeds.

Dye intermediates, also referred to as intermediates, refer to various aromatic derivatives used in the production of dyes and organic pigments. They are derived from benzene, toluene, naphthalene, anthracene and other aromatic hydrocarbons from coal chemical and petrochemical industries through a series of organic synthesis unit processes. With the development of chemical industry, the application range of dye intermediates has been extended to pharmaceutical industry, pesticide industry, propellant and explosive industry, information recording materials industry, as well as auxiliaries, surfactants, spices, plastics, synthetic fibers and other production sectors. There are many kinds of dye intermediates, and hundreds of them are more important. The most important early dye intermediates, such as nitrobenzene, aniline, phenol, chlorobenzene and phthalic anhydride, have been developed into important basic Organic Intermediates because of their wide use and large dosage. The annual output in the world is more than one million tons. The most important dye intermediates are o-nitrochlorobenzene, p-nitrochlorobenzene, o-nitrotoluene, p-nitrotoluene, 2-naphthol, anthraquinone, 1-aminoanthraquinone and so on. Starting from the above intermediates and through a series of organic synthesis unit processes, various intermediates with complex structures can be prepared.

Dye intermediates mainly include benzene intermediates, toluene intermediates, naphthalene intermediates and anthraquinone intermediates, in addition, there are some heterocyclic intermediates. The main reaction processes of intermediate in production are nitration, sulfonation, halogenation, reduction, amination, hydrolysis, oxidation, condensation and so on. The synthesis of a complex intermediate often takes many unit processes, sometimes using different basic materials and different synthetic routes.
