Non-polluted tea garden construction technology experience

In the past three years, I have been engaged in the construction of non-polluted tea gardens in the tea production process, made some useful trials, and also achieved some results. Now I will introduce the preliminary experiences of specific operations as follows: 1 The first is to solve the problem of excess pesticide residues. Rational Use of Drugs 1.1 Nineteen non-degradable pesticides are not used on tea plants and on jasmine trees. specifically is:
Dicofol, 666, DDT, 1605, 1059, omethoate, methamidophos, isocarbophos, toxaphene, heptachlor, chlordane, indomethacin, insecticidal guanidine, phosphoamine, fluoroacetamide, Benzion, Isophos, Monocrotophos, Carbofuran. 1.2 Main control methods for tea pests Widely used in agricultural prevention and control: I conducted experiments in Bailinhe City Tea Institute respectively, such as breeding and promotion of disease-resistant pests, cultivation of disease-free pests, rational planting, cultivation of tillage, and cultivation Weeding, proper harvesting, pruning, etc. may play a role in lowering the population or reducing the incidence of pests and diseases. The effect was also obvious. The number of pest control was reduced from 8 times per year before 1996 to 5 times in 1999, and the cost savings were nearly 50 yuan/666.7 m2.
Use plant quarantine as much as possible: Through quarantine, it is mainly to prevent spread of diseases and insects as seedlings are transported and spread.
Create conditions Apply physical and mechanical control: Apply a variety of physical factors and mechanical equipment to prevent pests and diseases. Such as: killing or removal; light trapping, sex traps induced insects and other insects.
Promote the use of biological control: (1) The use of natural enemies to control pests, such as the use of insectivorous insects, spiders, predators, insectivores and amphibians. (2) "Bacteria treatment of insects", the use of Beauveria bassiana 871 to prevent and control tea Lizard Weevil, the use of cypress pests to control black locust white peony, coconut garden quail, etc., the use of tea caterpillar virus to control tea caterpillars, etc. In the same year, we promoted the use of Tianba BTA biological pesticides at Bailin Lingtouping Tea Plant and received good results. (3) "Bacteria treatment" such as the use of agricultural anti-101 tea leaf blight prevention and control.
Prudent application of chemical control: At present, the pesticides that can be used within a certain range are: Bataan, Prazomide, Laurelin, Uranus, Killing Lingjing, Instant Exterminator, Dichlorvos, Colchicine, Moxa, and Kecate Tolk, enemy killing, kung fu, etc.
We vigorously advocate integrated prevention and control: I have adopted comprehensive prevention and control methods at the Baipinglingtou Pingpingchang and the City’s tea science field, striving to embody “prevention over treatment” to achieve effective control of pests and diseases. The problem of pesticide residues was gradually reduced, from 50% in 1996 to 34.6% in 1997, 14.6% in 1998, and 9.8% in 1999. 2 Promote the use of organic fertilizers or active bio-fertilizers Organic fertilizers have an effective nutrient balance, and contain a variety of trace elements that are suitable for the growth of tea plants. They also increase the permeability of the soil, improve the structure of the soil, and increase the ability to retain water and fertility. Therefore, we demand that the tea area use more organic fertilizer. For example, mature livestock, poultry manure and human waste, grass ash, cake fertilizer, mushroom fertilizer, compost, green manure and so on. In particular, new tea gardens, tea gardens, and other remodeled tea gardens will require organic fertilizers.
Bailing Ling Topingchang promoted the application of active organic bio-specific fertilizers, combined with the application of farmyard fertilizers, and usually applied only 5kg/666.7m2 of urea when germinating. The quality of tea was significantly improved, and the price of clove was increased by 8% compared with other teas. %.

Therapeutic heating pads usually operate from household current and must have protection against overheating.

A moist Heating Pad is used dry on the user's skin. These pads register temperatures from 76 to 82 °C (169 to 180 °F) and are intended for deep tissue treatment and can be dangerous if left on unattended. Moist Heating Pads are used mainly by physical therapists but can be found for home use. A moist cloth can be added with a stupe cover to add more moisture to the treatment.
