Can you eat freshly fertilized vegetables? How many days can I eat compound fertilizer watered veget

Freshly fertilized vegetables can be eaten after rinsing with water. If the vegetables that have just been sprayed with pesticides cannot be eaten raw, they must be soaked in alkaline water for 10 to 20 minutes, and then rinsed with water before eating.

The sentence about the fact that vegetables can't be eaten with dung water is Zeng Yi.

Academician Zeng Yi is an academician of the Chinese Academy of Sciences.

Academician Zeng Yi, an expert in viruses, means that you can't use fresh manure to water vegetables, so it is easy to leave the virus behind, especially if you just water it, it will be marketed, or it will be uprooted and sold with soil, and the virus will spread. If it is fermented manure water, there will be no virus residue when watering the vegetables.

People living in rural areas know that human and animal manure is the main source of organic fertilizer, and a few decades ago, that is, in the era when there was no chemical fertilizer, human and animal manure was the main source of fertilizer for crops. However, human and animal manure is not used for direct fertilization, and it must be subjected to degradation and high-temperature treatment before use.

Generally, the organic fertilizer fermented by livestock manure is better, and the farmers should dilute the amount of organic fertilizer with water before watering the crops, and besides, any crops and vegetables cannot be eaten raw without cleaning. So, if you talk about viruses alone, anything will carry viruses, it just depends on whether they are really harmful or not.

From human and animal manure to fertilizer, to fertilization to help vegetables grow, everyone should also think about whether it will pollute vegetables. To put it simply, the inside of vegetables cannot be polluted, but the roots and exterior of vegetables must have certain bacteria, as long as they are washed before eating and cooked at high temperatures, these bacteria can be killed, and there will be no harm to the human body.

Rural people use manure to water vegetables is also passed down from generation to generation, and the so-called existence is reasonable.

Besides, it has existed for thousands of years, and you can ask the ancestors if you can eat it. I remember when I was a child, the old man poured fermented manure on the roots of vegetables, and the plant was absorbed by the root diameter, and it absorbed some trace elements.

It's not for academicians to use big dung to eat vegetables, and besides, they are all watered at the seedling stage, and farmers can master the growth cycle, and the vegetables that have just been watered must not be eaten.

In fact, manure as an organic fertilizer is a very good fertilizer, which will not cause harm to the soil and can increase soil fertility very well, while the long-term use of chemical fertilizer will reduce soil fertility and soil compaction. However, because untreated manure contains a lot of eggs and germs, it is best to ferment or autoclave before fertilizing.

Freshly fertilized vegetables can be eaten, and they can be washed several times with water. If you have just applied pesticides, wash them several times with alkaline water.

Generally speaking, vegetables can be picked and eaten on the same day after fertilization, as long as they are cleaned. However, in order for the nutrients in the fertilizer to be completely absorbed by the vegetables, it is better to eat after 7-10 years of fertilization.

Fertilized vegetables are not pesticides, fertilizers are to supplement the nitrogen, phosphorus, potassium and humus of vegetable growth, this is fine, as long as you don't eat just pesticides.

It depends on what kind of fertilizer it is, if it is an amine fertilizer, it will increase the nitrate content, so it should not be eaten, and it will take three or four days.

Compound fertilizer can be mixed with water to water vegetables, generally one pound of compound fertilizer needs to be mixed with 200 pounds of water before it can be used, otherwise it will burn the roots of crops because the fertilizer concentration is too high. Compound fertilizer can not only supplement nitrogen, phosphorus and potassium elements, but also can supplement some trace elements, compared with some nutrients than a single fertilizer, compound fertilizer has more advantages in some aspects, but for some crops, partial application of a certain fertilizer can also effectively increase yield.

1. Can compound fertilizer be mixed with water to water vegetables?

1. Compound fertilizer can be mixed with water to water vegetables, generally one pound of compound fertilizer needs to be mixed with 200 pounds of water before it can be applied, but the concentration can not be too high, and the dose cannot exceed the standard, otherwise it will cause root burning.

2. However, the needs of different crops for the type, quantity and proportion of nutrients must also be diverse, and it is necessary to test the soil to understand the texture and nutritional status of the soil before using compound fertilizer.

3. Compound fertilizer should be used in combination with elemental fertilizer. The nutrient composition of compound fertilizer is fixed, and it can only be used in combination with various elemental fertilizers, or water-soluble fertilizer with fertile leaves to meet the nutrient needs of crops at different times.

2. How long after watering compound fertilizer can I eat.

1. After the compound fertilizer is watered, the nitrite content in the vegetables will be relatively high, and after the fertilizer effect is released for a certain time, it will be reduced after about 10 days, and it can be eaten at least after 10 days.

2. The main elements contained in compound fertilizer are nitrogen, phosphorus, potassium and other elements, and the varieties of compound fertilizer are different, and the proportion of nutrient content is different, which is usually used as base fertilizer or washed with water in the later stage of vegetable growth.

3. When picking vegetables, it is best after dusk, which is the time to experience the longest sunshine time, which is conducive to the dissipation of nitrite in vegetables.

Summary. In general, vegetables can be eaten 1-2 days after fertilizing. If foliar fertilizer is applied to it, it needs to wait for 20 days and should wait for the fertilizer effect to be basically released before eating.

If you also apply compound fertilizer, you will have to wait for 10 days or more if the fertilizer is released. The concentration of the fertilizer is different, so it is not clear how many days it will take, but it will be washed when you eat it in a few days.

In general, vegetables can be eaten 1-2 days after fertilizing. If you apply foliar fertilizer to it, you need to wait for 20 days, and you should wait for the effect of the fertilizer to be basically released before eating. If you also apply compound fertilizer, you will have to wait for 10 days or more if the fertilizer is released and the fertilizer is released.

The concentration of the fertilizer is different, so it is not clear how many days it will take, but it will be washed when you eat it in a few days.

Is it very harmful to the body to accidentally eat leeks that have been applied with compound fertilizer?

I heard that salt nitrates, carcinogens, are there any remedies?

Generally, after watering chemical fertilizer, Zheng Yi can eat it one day later. Chemical fertilizers act on the roots, and the toxicity of chemical fertilizers is very low and will not cause harm to people. Chemical fertilizer refers to the chemical method of manufacturing or mining ore is a fertilizer, also known as inorganic fertilizer, including nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, micro fertilizer, compound fertilizer, etc., they have the following common characteristics:

The composition is simple and the nutrient content is high; The fertilizer effect is fast, and the fertilizer is strong; Some fertilizers have acid-base reactions; Generally, it does not contain organic matter, and there is no effect of soil modification and fertilization.

Summary. Pro, after the compound fertilizer is watered, relatively speaking, the nitrite content in vegetables, especially leafy vegetables, is higher, and the fertilizer effect is released for a certain time, and it will be reduced after about 10 days, so it can be eaten at least ten days later.

Compound fertilizer mainly contains nitrogen, phosphorus and potassium and other elements, different varieties, different nutrient content ratios, usually used as a base fertilizer and in the later stage of vegetable growth with water. The total amount of nutrients in compound fertilizer is generally relatively high [8u58 medicinal material network, there are many types of nutrients, and a single application of compound fertilizer can at least be more than two main nutrients of crops at the same time.
