Can you spray pesticides in the process of tea planting, and do you need pesticides for tea?

1. Except for the tea trees that are certified as organic tea gardens, pesticides are not allowed to be sprayed during the planting process, and pesticides are generally sprayed under other circumstances. Pollution-free or green certification only restricts the use of highly toxic pesticides. Drinking organic tea should not have pesticide residues.

Pesticide residues, heavy metals, and harmful microorganisms are one of the key controls).

2. Standardized tea production, no pesticides are allowed to be sprayed half a month before picking fresh leaves, which is constrained in the industry, and the state will also sample and inspect the quality. The standardized tea pesticide residues have a certain range of control, and they cannot leave the factory if they are exceeded.

3. Most pesticides are insoluble in water, and the content is low, and they will not be soluble in tea soup during the brewing process.

4. It is best not to eat the tea residues, so that the pesticide residues that are insoluble in water may be ingested.

There are nearly 500 kinds of ingredients in tea. There are mainly caffeine, theophylline, theobromine, choline, xanthines, flavonoids and glycosides, tea tannins, catechins, terpenes, phenols, alcohols, aldehydes, acids, esters, aromatic oil compounds, carbohydrates, vitamins, proteins and amino acids. Amino acids are cysteine, methionine, glutamic acid, arginine, etc.

Tea also contains calcium, phosphorus, iron, fluorine, iodine, manganese, molybdenum, zinc, selenium, copper, germanium, magnesium and other minerals. These ingredients in tea are beneficial to the human body, especially manganese, which can promote the formation of vitamin C in fresh tea and improve the anti-cancer effect of tea. Their combined effect is of great significance to the prevention and treatment of diseases in the human body, so there is a saying that "you can't go without tea for a day".

According to a certain density (3000-8000 plants per square meter), double rows and double plants (or single row and two plants). Then according to the fertilization management of each growing season, the control of pests and diseases, plastic pruning (section.

In one or two years, it is mainly pruned to make the tea trees gradually form tea tents).

"Seed" insect control. That is, to reduce the occurrence of pests and diseases by adopting appropriate planting methods. For example, when opening a new garden, seedlings without diseases and insects are used, and sprayed with a new high-fat film solution to repel underground diseases and insects, isolate virus infection, and improve the ability to resist natural disasters.

Try to adopt the method of cluster planting or strip planting to avoid excessive dense planting and create a good ecological environment of tea gardens; Reasonable intercropping in tea gardens to prevent large-scale monoculture, so as to maintain abundant natural vegetation and reduce the probability of large occurrence of pests and diseases.

To harvest (cut) insect control. Timely picking, reasonable pruning, and timely application of callus antiseptic film on the cutting edge to promote wound healing and prevent germs from invading and infecting. It can improve the ventilation and light transmission conditions of tea gardens, and inhibit the occurrence of black-thorn whiteflies and scale insects under humidity-loving or canopy-loving conditions.

The buds and leaves of insects should be re-harvested and strongly harvested. In summer and autumn, try to pick as many leaves as possible and leave fewer leaves. If there are many pests in autumn, the harvest can be extended and the closure of the garden can be postponed appropriately.

Fertilizer to fight insects. The application of organic nitrogen fertilizer could improve the resistance of tea plants to tea orange gall mites. The application of lime is not conducive to the survival of thrips and leafhoppers; The phosphate rock powder extract is used as top dressing outside the roots, which can kill red spiders. Heavy application of basal fertilizer, reasonable topdressing of spring fertilizer, summer fertilizer, autumn fertilizer, organic fertilizer as the mainstay, chemical fertilizer as a supplement, nitrogen, phosphorus and potassium balanced application, and pay attention to drainage, irrigation drought prevention and spraying strong stems, so that the plant stem is thick and strong, and the plant is lush.

It can significantly improve insect resistance, reduce the amount of pesticides and fertilizers, and reduce residual toxicity.

You can choose to spray with glyphosate or glufosinate-ammonium herbicide, and if the tea tree is relatively large, the concentration needs to be increased.

Paraquat, but older tea leaves should only be plucked and not killed with herbicides.

The best way is to use some pesticides that are specifically designed to remove weeds, and spray them regularly, which can effectively remove the tea tree and inhibit its growth.

Tea is a natural beverage with a long history, and even in contemporary times, it is still widely used, and there are fanatical tea enthusiasts in both the East and the West. And in recent years, due to various scientific studies that have verified the health benefits of tea, tea has slowly become popular in the circle of young people.

Food safety is the top priority in social issues, although tea safety is not as often mentioned as rice and flour oil, but for tea lovers, it is also a special concern for you. At present, there are all kinds of tea on the market, and the price fluctuates greatly, and each touted how good their tea is, but everyone has no way of knowing how good their tea is. Especially the pesticide residues in the tea, that is also the same old tune of the problem, is the tea all chemical fertilizers, can you not drink the chemical fertilizer Biluo spring tea?

Pesticide residues must be measured by a standard, which is to apply the MRL (Greater Allowable Limit) specification promulgated in China, and pesticide residues can only be considered as a safety hazard to food if they are higher than this standard. At present, the application of chemical fertilizer in tea is a normal agricultural and animal husbandry countermeasure, which depends on the variety, amount of chemical fertilizer used and the safety interval. Most of the vegetables and fruits we usually eat and drink are safe, because there are pesticide residues but not exceeding the standard, and they cannot harm their physical and mental health.

Some Camellia oleifera trees grow in the high mountains of the plateau area, and due to the regional environment itself, it is not easy to produce insects, so these Camellia oleifera trees are basically not sprayed. Generally, new tea is chemical-free, with fewer pests and diseases in spring and more pests and diseases in autumn and winter, so some chemical fertilizers will be used. However, the residence period of chemical fertilizer is also limited, and if you go to pick tea after the residence period, there are very few pesticide residues, so you can rest assured.

Even if there are some pesticide residues in tea, it does not mean that we will drink pesticide residues in our stomachs when we drink tea. At present, many chemical fertilizers used for Camellia oleifera are all fat-soluble, most of them are pesticide varieties with very low water solubility, which are absorbed on the organization of tea, and are not easy to accompany the brewing to the tea soup, and the content in the tea is generally only about 1. In that way, based on the world's highest average tea consumption of 10 grams a day, even if this tea has a little pesticide residue exceeding the standard, the stomach is almost zero when you really drink it with tea.

Choosing well-known brands with guaranteed quality and selecting safe and secure tea products is also the premise of drinking tea and buying tea.

So what do you think about this? Feel free to share your thoughts and thoughts!

I think that as long as qualified pesticides are used under normal regulations, of course, you can drink with confidence, and if you use pesticides, it is only to keep the tea from being eroded by some pests, and as long as these pesticides are within the controllable range of the law, they will not affect the use.

Yes. We should look at this problem rationally, rather than when it comes to pesticides, pesticides are not flood beasts, and it can not only protect crop yields, but also improve the quality of agricultural products, which is also one of the reasons why naturally grown fruits, fruits without pesticides and fertilizers are in good condition and good taste.

It is safe to drink because most of the pesticides are washed off before stir-frying the tea.

You don't have to use pesticides, and the tea I drink doesn't use pesticides. Also, I was reluctant to drink it because of the high level of spring tea, and the spring tea in this house was produced and sold by tea farmers.

In addition, in order to increase agricultural production in some places, tea leaves are sprayed with pesticides, and the tea leaves are not cleaned before they are made. Normally, when you make tea, the first tea is brewed to wash away pesticide residues, which is unscientific.

Also, there are pesticides and non-pesticides for tea. The book "Color Atlas of Tea Tree Pests and Diseases" lists pests and diseases that can harm tea trees. When is the pest and disease hazard, when to spray.

Therefore, the pesticides are not the same, and the harm is not the same, so we should pay attention.

If you want to buy safe tea without pesticides, you can book on the official website of Hospitality Jiupin, which is stocked under the tea tree, with fewer pests and strict quality control.

Of course, tea needs to be pesticides, but now the medicine for tea is basically low-toxicity! Later, because the workmanship will be fried at high temperature, there is no need to worry too much.

But because the tea leaves are directly made into dry tea without cleaning, it is best to clean it first when drinking tea, and the cleaning method is very simple, the first tea water is soaked for 30 seconds and poured out!

Some don't, some will fight, look at the geography and planting techniques, satisfied.

<> tea plants generally need to be sprayed with pesticides. Under normal circumstances, the tea trees planted need to be sprayed with pesticides, after entering the summer, when the temperature rises in the large-scale planting of tea gardens, pests are easier to multiply on a large scale, if pesticides are not used, it is likely that the tea trees in the entire tea garden will be infringed, so the general tea garden will spend the summer by pruning and spraying.
