Now the tea is very polluted, but what are the sources of its pollution? And how to solve it? 10

Mainly air pollution, but also soil pollution and water pollution, as well as the harm of acid rain, and even the greenhouse effect, abnormal climate, etc., can pollute tea and affect the quality of tea. To solve this problem, the main thing is to do a good job in environmental protection, such as treating urban industrial sewage and domestic water to make it meet the national emission standards, and strictly controlling the emission of nitrogen oxides and sulfur oxides, as well as other toxic and harmful gases.

Factories that pollute the environment can be sued. Environmental pollution disputes are subject to no-fault liability, that is, regardless of whether the standard is met, regardless of the subjective state, as long as the infringement is caused, the responsibility must be liable. In addition, the proof of environmental pollution is reversed, and the polluter proves that it is not responsible.

If you go to the relevant remediation department, such as the environmental protection department, you can only hold the polluter administratively responsible, and at the same time, you can mediate, but if you judge the polluter's civil liability, it can only be done through litigation.

Air pollution is the main thing, as well as soil pollution, etc., and if you want to solve it, you must act for all! There's no way around it, but you can start with you and don't litter!

In the control of tea tree diseases and insects, chemical control is a major measure, but chemical pesticides have the shortcomings of killing natural enemies, high toxicity, easy to make pests resistant and causing residual pollution to tea and the environment. There are many varieties of chemical pesticides, and their properties, modes of action, and prevention and control objects are also different. The following are the commonly used medicines suitable for tea gardens:

1. Trichlorfon has stomach toxicity and contact killing effect, and the main dosage form is 90% trichlorfon crystals. It is mainly used for the prevention and control of leaf-eating pests such as tea caterpillars, stinging moths, leaf roller moths, demoiselle moths, inchworms, etc., with a dilution factor of 1000 times and a safety interval of 5 7 days. 2. Dichlorvos has the effects of contact killing, stomach poisoning and fumigation, and the main dosage form is 80% emulsifiable concentrate.

It is mainly used for the prevention and control of leaf-eating pests such as tea caterpillars and moths, tea aphids, tea thrips, small green leafhoppers, blackthorn whiteflies, etc., with a dilution factor of 1500 times and a safety interval of 5 days. 3. Dimethoate has the effect of contact killing and plant systemic conduction, and the main dosage form is 40% emulsifiable concentrate, which is used for the prevention and control of small green leafhoppers, tea aphids, blackthorn whiteflies, scale insects and tea moth larvae in the leaf-laying stage. Dilute 2000 3000 times with an interval of 7 to 10 days.

4. Marathon has contact killing, stomach toxicity and fumigation dosage form, which is 50% emulsifiable concentrate. It is mainly used to control various scale insects, and also has a certain effect on tea caterpillars, inchworms, tea aphids, blackthorn whiteflies, and tea mites. Dilute 800-fold.

The safety interval is 10 days. 5. Phosphine has stomach toxicity and contact killing effect, the main dosage form is 50% emulsifiable concentrate, mainly used for the prevention and control of tea caterpillars, tea silkworms, inchworms, stinging moths, leaf roller moths, demoiselle moths, tea aphids and scale insects. Dilute 1000-fold with a safety interval of 3 to 5 days.

6. Bataan has the effects of internal absorption, contact killing, stomach poisoning and food rejection. The main dosage form is 90% wettable powder. It is mainly used to control leaf-eating pests such as weevils and inchworms and tea caterpillars in tea gardens, and also has a certain effect on small green leafhoppers, diluted 1500 times, with a safety interval of 15 days.

7. Pyrethrin dosage form has 20% emulsifiable concentrate, moderate toxicity, strong contact killing and stomach toxicity, wide insecticidal spectrum, efficient for lepidopteran larvae, mainly used for the prevention and control of poisonous moths, inchworms, leaf moths, spiny moths and small green leafhoppers, dilution factor of 6000 times, safety interval of 10 days. 8. Cypermethrin, also known as Xingmian Bao, Chlorpermethrin, dosage form is 10% emulsifiable concentrate, moderate toxicity, with strong contact killing and stomach toxicity, rapid efficacy, long residual effect, mainly used for the prevention and control of lepidopteran larvae, and the treatment of small green leafhoppers, aphids, scale insects, thrips, dilution times 6000 8000 times, safety interval of 5 days. 9. The insect control sperm form is 10% emulsifiable concentrate, which has the effect of contact killing and stomach toxicity, and is mainly used for the prevention and control of tea caterpillars, inchworms, stinging moths and aphids, diluted 6000 times, and the safety interval is 3 days.

1. Rare earths, which are used in agriculture, can promote root growth and plant photosynthesis, but there are standards for use, and excessive use is counterproductive. There is one thing we have to recognize, aside from the actual only talk about the theory that is empty talk, rare earths are only in mining areas, and long-term excessive contact will be harmful to the body, rare earths are insoluble in water, plants absorb, it exists in the cells, will not run to the surface, you can soak out of the water is minimal, and will not affect the body, now many seedlings, will be used, such as phytoxin. Suffice it to say, don't worry about this.

The use of pesticides is a truth, I will tell you, don't the vegetables in the vegetable market now be sprayed? Don't worry, I'm all drugged, even if I grow vegetables at home, or the bugs will be eaten up, what will I eat? The state has relevant regulations for the use of some pesticides, and the medicine also has an expiration date, how long after, basically invalid, do not worry too much.

2. Don't be too greedy when buying, you have to get 100 pounds of tea at the very least, drink less tea picked in summer, drink less strong tea, don't soak for a long time, and the best way to brew kung fu tea, so that you can avoid less intake. If you look for something organic, non-pesticides, thousands of yuan a catty, I don't think it's necessary, tea farmers drink their own tea, just like those who grow vegetables, everything has to have a degree, what you said is extreme, not so exaggerated.

3. Calm down, don't give up a forest because of a tree, and drink tea with confidence.

In fact, it is not so serious, the problem exists, but it does not mean that it cannot be drunk, my country is still very strict with tea safety standards, many brands are also improving, and now many advocate ecological planting.

Rare earths are widely found in soil, water, atmosphere and living organisms, and humans cannot avoid them. Rare earths in nature enter plants and animals through soil, air, and water, and then enter the human body through the food chain. The rare earth content of tea comes from the growth process:

One is that tea plants absorb rare earth metals from the soil; The second is the spraying of rare earth "fertilizers" to cause residues in tea.

No, because even if you spray pesticides, the amount cannot be too large, let alone spray and pick, it will slowly oxidize after rain and time, and then pick after more than 20 days, not as serious as you think.

Please rest assured as much as possible that the greens we eat every day are sprayed with pesticides, and we still eat greens every day. Compared with green vegetables, tea has a long growth period, and even if pesticides are sprayed, it is far less than the green vegetables eaten every day. In addition, the pesticide of tea is specially researched and required by the Ministry of Agriculture, which is an environmentally friendly and green organic pesticide! ~

It's a purely malicious attack, it's not that exaggerated at all, because Japan, the European Union, their standards and international standards are different, that's deliberately harsh on our country, we ourselves are doing Tieguanyin, as early as a few years ago, Anxi County banned the use of highly toxic pesticides, and besides, our fellow villagers drink Tieguanyin every day, I grew up so old that I have heard of drinking and drinking the dead, and I have never heard of drinking tea and drinking the dead!

Hehe, no, how many years of history.
