Three strokes teach you to produce pollution-free tea
As people's attention to themselves increases and advances, “no pollution†and “no pollution†will become the people's dietary choices. Under this background, millions of tea farmers in our province want to obtain good income in tea, an important approach It is a pollution-free tea. However, "pollution-free" is simple to say. Many people still feel that they have no way to start. In view of this, this reporter recently made a special trip to the Institute of Tea of ​​the Provincial Academy of Agricultural Sciences to discuss the latest non-pollution cultivation techniques for tea with Wang Yun, the main researcher of the “Nuisanceless Tea Demonstration Base Construction†project. Wang Yun said that they will “transform†the non-pollution cultivation techniques of ripe tea in Mingshan County into three strokes. Farmers will continue to operate according to this, and they will not be able to find good tea. Wang Yun, the first recruiting block, said that the premise of pollution-free tea production technology is to choose a good land, not only to produce good tea, but also to stay away from cities, factories, and roads because of the exhaust of cars. Dust and waste water discharged from the factory can contaminate the tea garden. The construction of pollution-free tea gardens should select areas with good ecological conditions, no pesticides and heavy metal pollution in the environment (to determine the content of lead and other heavy metals in the soil before the construction of the park), and prevent pesticides and heavy metals from affecting tea from the beginning of construction. Pollution. For the tea garden's own small environment, it is necessary to build a good ecological environment through reasonable close planting, tea plantation, and to purify the atmosphere and water and soil pollution, and enhance the natural control ability of natural enemies of tea gardens on pests. The second measure of insect pest attack Wang told reporters that if the tea garden is not polluted, the best way is not to use pesticides, or less medication.

Good results. For the prevention and control of pesticides, we must also choose high-efficiency, low-toxicity and low-residue organic phosphorus and chrysanthemum pesticides. The use of highly toxic and high-residue pesticides is strictly prohibited. In addition, the use of omethoate and water-sulfuric acid should also be reduced, and strict drug concentration, drug use time, and fresh leaf picking interval should be taken into consideration, and attention should be paid to the protection of natural enemies. In fact, it is reasonable for pests and diseases to cause certain losses to tea. The third step is to process the most important part of the tea leaves, which are the most important ones after processing. According to Wang Yun, tea should be packed with clean utensils before it enters the processing plant, and it should not be used with copper ware, but should also be protected from contaminants such as pesticides that can easily cause pollution. After the tea leaves the factory, the processing machinery should use lead-free, copper and other heavy metals contaminated alloy equipment, such as stainless steel fixing machine, kneading machine, forming machine and other processing, in order to ensure that the product is not subject to heavy metal pollution during processing. The problem of harmful bacteria should be strictly controlled by the processing and hygiene management of the tea factory. There should be sanitary requirements for the fresh leaf plots and the environment of the tea factory. For example, the clothing of workers, the hygiene of packaging equipment and places should be strictly managed. Wang Yun said that one of the major problems faced by the production of pollution-free tea in our province is that tea farmers cannot effectively monitor the production process of tea under the operating status of the household. Therefore, he believes that the tea farmers should be organized in various forms (such as the company plus farmers) to implement the pollution-free tea production technology. Only such prevention and control can achieve low cost and good results.
