What are the harms of using uncooked organic fertilizer for vegetables? How to take the right medica

The application of organic fertilizer without manure is mainly organic chemical state, and the root system of vegetables can not digest and absorb nutrients, which is equivalent to no fertilizer, which harms the growth and development and production of vegetables. Organic fertilizer is organic fertilizer, which is human and animal excrement, straw fertilizer, domestic garbage disposal, etc., which have a complicated origin. Organic fertilizer can kill parasite eggs, lawn seeds, green plant pathogens, etc.

If there is no manure and vegetables are sprayed with farm manure, people who eat such vegetables are very susceptible to parasites. The weeds in the vegetable field are more luxuriant, which endangers the growth and development of vegetables, and the application of herbicides produces environmental pollution of vegetables in order to manipulate the weeds. In addition, plant viruses and bacteria have not been killed, and vegetables are very susceptible to diseases, resulting in a decrease in vegetable production.

Organic fertilizers are mainly derived from green plants and/or small animal residues, and are carbon-containing substances whose main function is to provide nutrients to plants in the soil layer. It is produced and processed by microbial chemicals, animal and plant wastes, and green plant residues, which remove toxic and harmful substances and contain many beneficial chemicals, including: a variety of organic substances, peptides and a variety of trace elements including nitrogen, phosphorus, and potassium.

Organic fertilizer is rich in a lot of organic matter, and it is an area where a variety of microbial strains grow, develop and reproduce. According to Huang Jingchun's scientific research, the ratio of nitrogen-fixing bacteria in the soil layer has been nearly doubled, and the ratio of organic fertilizer has been nearly doubled, <>

The number of chemical fibrolytic bacteria increased by nearly 2 times, and the biological community of other microbial species also increased significantly, so the application of organic fertilizer could greatly promote the maturation process of newly opened land resources. In addition, organic fertilizer can also produce a variety of phenols, vitamins, enzymes, auxin and other chemicals in the process of decomposition, which can promote the growth and development of crop roots and the digestion and absorption of nutrients. Experiments have confirmed that rapeseed cake is often especially reasonable in tea plants, not only because rapeseed peanut bran is rich in nutrients, but more importantly, rapeseed cake produces a chemical that can stimulate the growth and development of the root system during the decomposition process, and promote the growth and development of tea roots and the absorption of nutrients.

Other organic fertilizers also have similar effects.

Until every year when ploughing or autumn planting, it will be carried to the fence according to the manure removal port, and then transported to the field as a base fertilizer for crops. Naturally, there is also the use of manure on the edge of the field. Generally speaking, the surface of the manure will be smeared with a layer of grass mud, in order to ensure that the organic matter of the soil fertilizer does not evaporate, and to ensure the moisture of the soil fertilizer, which is beneficial to the rot of some chemicals inside.

At the same time, the heat generated in the case of manure will also destroy the larvae and pathogenic bacteria in the animal manure, ensuring the safety of vegetables. It is very easy to lead to more root diseases and pests: unfermented organic fertilizer generally carries a lot of harmful bacteriaIn particular, animal feces will retain a large number of harmful bacteria such as Escherichia coli, resulting in vegetable root diseases and pests, and sometimes leading to dead seedlings.

Burning seedlings may seriously affect the growth of plants, may lead to stunted plant development, and there may be deformities in the growth of vegetables. It is necessary to take into account the specific composition of the chemical agent, and also to take into account the problem of ***, and try not to choose the toxic one.

This may burn the seedlings, may carry a lot of germs, may have insect eggs, and may cause pests and diseases. To choose a relatively small agent, we must grasp the concentration of the agent, and do not choose a high concentration of pesticides.

The use of unripe organic fertilizers can lead to damage to the soil, but it can also lead to soil deterioration, which can also affect the soil quality. It will cause vegetables to be greatly affected, and it will also lead to a decrease in the yield of vegetables. When using this organic fertilizer, it must be incubated and matured.

Let's talk about farmhouse fertilizer first, farmhouse fertilizer is the manure of all animals and poultry raised in the countryside, including human manure, mixed with soil and piled together, after a long time of piling and fermentation. Organic fertilizer is to use the rural waste orange crops to fertilize is the basis for promoting agricultural harvest, with the social and economic development in recent years, organic vegetables approached people's tables, at first we don't understand what organic means, because it feels so strange and distant.

Rotting manure is a process from the fermentation of farmhouse fertilizer, also called farmhouse fertilizer, making farmhouse fertilizer is a very troublesome process, it requires a large area of empty space, in the countryside, you will be on the edge of the ditch, the field and the wheat field, everywhere you can see a pile of manure, now the farmland is less and less to apply farmhouse fertilizer, on the one hand, because a single farmer has no farmhouse fertilizer to use, the farmer health system has also made the production of farmhouse fertilizer on a large scale, and most of the animal manure has become a raw material for the production of organic fertilizer.

If fresh manure is used as the base fertilizer, its nutrients are difficult to be absorbed by cropsManure contains a large number of pathogenic microorganisms and parasite eggs, which can pollute the soil after application, and the heat generated by fermentation in the ground will also occurDamage to crop roots, easy to burn roots. Well-rotted farm manure is conducive to the consumption of livestock manure resources in rural areas. In rural areas, the amount of livestock and human manure is relatively large.

In the eyes of ordinary people, these things are disgusting and filthy things, and they should be avoided from afar. But in the eyes of farmers, the fermentation process of farm manure is very simple, first pile up the animal manure, fill it with water, cover it with soil, and then wait until the second year to use, it is generally used by this method to decompose, although the fermentation time is very long, but there is still a great chance that the decomposition is not complete,.

It is processed with animal manure in a factory. To put it bluntly, organic fertilizer is sterilized, while farmhouse fertilizer is naturally fermented without sterilization treatment. Farm manure has not been sterilized, and harmful insect eggs are in it, which is sometimes harmful to the dealer.

Organic fertilizer refers to the process of converting waste organic matter into fertilizer through the fermentation of microorganisms under artificial control and certain moisture, C N and ventilation conditions. Through the composting process, the organic matter is transformed from an unstable state to a stable humus substance, and its compost products do not contain pathogenic bacteria, weed seeds, and are odorless and fly-free, which can be safely handled and preserved, and is a good soil conditioner and organic fertilizer.

There are two main meanings of fermentation:

1. Kill pathogenic bacteria, grass seeds, etc.

2. Through the process of mineralization and humification, the organic matter is converted into substances that are easily absorbed by plants. It also improves the texture of the soil.

When fruit trees or vegetables are applied with organic fertilizer as fertilizer, it is indeed required to apply well-rotted organic fertilizer. This is usually called "cooked fertilizer" or "raw fertilizer" in rural areas, mature fertilizer is organic fertilizer after full decay, and raw fertilizer is organic fertilizer without decay and fermentation treatment.

Because this allows the microorganisms inside to completely ferment the organic matter. It is convenient for the absorption of plants, so that plants can grow and survive better. And it also kills the bacteria in it.

Because only when they are decomposed, some of the organic matter in these plants can be fermented and can be absorbed by plants.

Many farmers do this because rotting allows vegetables to absorb nutrients better and increases yields.

In this way, you can ensure that the nutrition of the vegetable is sufficient, and later it can also avoid pests, and then you can also ensure that the juice is sufficient and the nutritional value can be guaranteed.

Because after treatment in this way, the nutrients in the fertilizer can be fully stimulated, and the effect is better.

Because the value of such vegetables is very high, and the yield is also very high, there will be no corruption problems in the later stage.

Because this can make the vegetables grow stronger and make the vegetables look better.

Advantages of bio-fertilizers.

1.Improving the soil:

1) Through the proliferation of beneficial bacteria, a large number of beneficial bacteria form a dominant population around the plant roots.

2) Through the activities of beneficial bacteria, the soil organic matter is quickly decomposed, so that the formation of soil aggregates makes the fertilizer, water retention, water supply and air permeability well adjusted.

3) Decompose pesticide residues in the soil to avoid pesticides causing harm to the next crop. It is also suitable for harmful substances discharged from roots during the decomposition of plant growth.

2.Improving the quality of crops, while releasing phosphorus and potassium, can promote the release of trace elements in the soil, which is the utilization of crops at the same time, beneficial bacteria metabolize and produce a variety of substances required by plants, such as small molecule amino acids, vitamins, etc.

3.Achieve the role of biological control of diseases. Root irrigation can control the germs in the soil and spray them on the leaves to prevent diseases.

4.Make crops mature early and prolong the harvest period. Due to the improvement of soil physical and chemical properties, soil nutrients are rich and balanced, and the fertilizer in the soil can be better absorbed by crops, so it can make crops mature early and prolong the harvest period.

5.Unlike chemical fertilizers, bio-bacterial fertilizers can bring excess soluble nutrients into the soil at one time, biological fertilizers can avoid environmental pollution, and beneficial bacteria continue to multiply and metabolize around plant roots. Continuously provide nutrients to crops.

As long as it does not contain chemicals, it can be used, of course, it is better to change it with the word "organic". Inorganic chemical hormones and antibiotics can't be used.

There are many types of pesticides and chemical fertilizers that should not be used on vegetables, and the following are some common pesticides and fertilizers that are not suitable for use on vegetables:

1.Dichlorvos: This pesticide is converted into compounds similar to neurotransmitters in the body, which is more harmful to the human and animal nervous systems. Therefore, it should not be used on vegetables to avoid poisoning after consumption.

2.Methaloxine: This pesticide will produce toxic nitrosohyoylcarbamate methyl ester after decomposition, which is carcinogenic to humans. Therefore, it cannot be used on vegetables to avoid harm to the human body.

3.Paraquat: The main ingredient in this herbicide is glufosinate-ammonium, which can cause organ damage and soil and water contamination over time. Therefore, it should not be applied on vegetables to avoid contaminating the food.

4.Dicofol: This insecticide can remain on the surface of vegetables, which has an impact on the liver and kidneys of the human body, and consumers are prone to poisoning, especially children and pregnant women. Therefore, it should not be used on vegetables.

5.Aminophosphaline: This insecticide can affect the nervous system of the human body and may cause headaches, dizziness, nausea and other discomforts. Therefore, it should not be used on vegetables.

In short, pesticides and fertilizers that are harmless to the body should be chosen to effectively protect vegetables, rather than using these potentially harmful pesticides and fertilizers.

Pesticides and fertilizers that are not suitable for use in vegetables include organomercury preparations, organochlorine preparations, organophosphorus preparations, ammonium nitrate, ammonium chloride, potassium chloride.

Fujilong, Saili Pin, Mercury, Cilisheng, Flying Phosphorus, Liuliu Imitation Six, Dichlorvos, Trichlorfon and other pesticides and fertilizers, the main loss is that there are too many chemical components and are easy to damage.

They are organomercury preparations, organophosphorus preparations, organochlorine preparations, ammonium chloride, potassium chloride, etc., which cannot be used on vegetables.

<> fresh livestock manure, gasket materials, and plant stems and leaves are all part of Wuxiao rotted organic fertilizer after fermentation at high temperature or room temperature. During fermentation, it is necessary to ensure that the ambient temperature of the periphery is not lower than 10 °C, and the materials are mainly divided into four cycles of heating, constant temperature, high temperature and cooling in the fermentation process. Organic fertilizer is very rich in organic matter and various nutrients to provide nutrients for crops.

After the organic fertilizer is decomposed, it can also provide energy and nutrients for the soil microbial cavity grinding activities1. What are the well-rotted organic fertilizers?

1. Fresh livestock manure, gasket materials, and plant stems and leaves are all decomposed organic fertilizers after fermentation at high temperature or room temperature. Fresh livestock manure needs to be decomposed into nutrients and humus in a usable state of crops through the action of microorganisms during the accumulation process.

2. During fermentation, it is necessary to ensure that the ambient temperature of the periphery is not lower than 10 °C, and the materials are mainly divided into four cycles of heating, constant temperature, high temperature and cooling in the fermentation process. When the material continues to heat up to the constant temperature stage, it will kill harmful bacteria, weed seeds and eggs of diseased insects, but the temperature should not exceed about 70 °C, otherwise it will cause the loss of beneficial bacteria.

3. Organic fertilizer is very rich in organic matter and various nutrients to provide nutrients for crops. After the organic fertilizer is decomposed, it can also provide energy and nutrients for soil microbial activities, promote microbial activities, accelerate the decomposition of organic matter, and the active substances it produces can promote crop growth and improve the quality of agricultural products.

Second, what crops can organic fertilizer be used on?

1. Basically all crops can use organic fertilizer, organic fertilizer is neutral (some slightly acidic) slow-release fertilizer, generally as long as it is well-rotted organic fertilizer will not harm crops. Organic fertilizer is very good for vegetables, vegetables are easier to accumulate nitrate, if you apply organic fertilizer can significantly reduce the nitrate content, eat vegetables with organic fertilizer is better for the body.

2. After the organic fertilizer enters the soil, it can be condensed into new humus after microbial decomposition, which can be combined with the clay and calcium ions in the soil, and then form an organic and inorganic complex to promote the formation of water-stable aggregate structure in the soil, so as to coordinate the contradiction of water, fertilizer, gas and heat in the soil. Organic fertilizers can also reduce soil bulk density, improve soil cohesion and adhesion, and make tillage better. Because humus is loose and porous, the adhesion and cohesion are smaller than clay and larger than sand, so it can not only improve the porosity and aeration of cohesive soil, but also change the loose state of sand.

3. Long-term use of a large number of chemical fertilizers will lead to an increase in soil pathogens and insect eggs, and if not treated in time, it will spread pathogens, increase the concentration of ammonia, nitrate and soluble organic nitrogen in groundwater, and eutrophication of surface and groundwater, resulting in deterioration of environmental quality and even endangering the survival of organisms. Therefore, the rational use of organic fertilizers can not only reduce environmental pollution, but also reduce fertilizer inputs.
