What kind of vegetables are considered greens? What are the precautions for growing green vegetables

With the improvement of people's living standards and quality, pollution-free vegetables are sought after by people. In the face of this situation, how to quickly produce pollution-free vegetables and how to manage them to better meet people's needs are the current research hotspots. The most important part of the so-called green pollution-free vegetable planting is the choice of planting environment.

Generally, vegetable planting needs factors such as sunlight, air, and water, but green vegetables have relatively high requirements for the planting environment.

It should only be cultivated in an environment suitable for growth. Green vegetables should be grown far away from people's living environment. Because the place where humans live is seriously polluted, the water quality is not up to the requirements, and water is the main factor for the growth of vegetables.

Therefore, it is important to choose an area where green vegetables are grown far away from areas where people live, so as to provide the purest water source for green plants. If you choose to plant plastic greenhouses, you should choose an area with relatively pure water quality. Otherwise, the vegetables grown are not green and pollution-free vegetables.

Green vegetable cultivation must not only meet the requirements of pure, pollution-free water, but also meet standard soil requirements. The selected soil must meet the following conditions: the nutrient content should be comprehensive, the soil should be rich in organic matter, and the soil should have a strong resistance to insects.

The requirements for the soil are relatively high, and the selection should be cautious and cautious. For a piece of land, the technical department must first set up an inspection team to collect soil samples for inspection, and only after reaching the standard can it be planted.

Pollution-free vegetable cultivation also has high requirements for fertilizers, and the use of any fertilizer must be carefully considered. Among them, green organic chemical fertilizers are mainly used, and inorganic chemical fertilizers are mixed at the same time. Reasonable fertilizer formula can promote the rapid growth of green vegetables and ensure sufficient nutrition during the growth of green vegetables.

Green vegetables can also use a variety of compound fertilizers to promote vegetable growth during the growth process.

Pollution-free vegetable planting is a thing worthy of people's attention, and it is necessary to choose the right soil before planting. Technicians should sample the soil of the plantation and plant it in the area after meeting the growth requirements of pollution-free vegetables. In addition to soil selection, fertilization is also an important thing.

The requirements for fertilizer are relatively high, and technicians have to go through many tests to choose the most suitable fertilizer for green vegetables. Chemical fertilizers can provide a lot of nutrients to vegetables, but pollution-free vegetables cannot use chemical fertilizers. Because, if not used properly, the vegetable leaves will fall off and the surrounding environment will be damaged.

Pesticides with relatively large medicinal properties should also be used with caution.

Green vegetables are not sprayed with any pesticides, fertilization is to use home fertilizer, such fertilizer is the safest, planting green vegetables need to pay attention to his heat preservation, soil fertility, irrigation water, if necessary, you can build a greenhouse, planting green vegetables to pay attention to temperature and humidity.

The body contains vitamins, and there are no residual pesticides on the body surface are green vegetables, and the light is sufficient; catch insects regularly; Regular fertilization; watering daily; Use more calculated fertilizers.

Pure natural no chemical fertilizer added, no pesticide vegetables are green and healthy vegetables, planting green vegetables to pay attention to the prevention and control of insects, to try to use natural fertilizers such as manure.

Now, green vegetables are generally called pollution-free vegetables. Refers to vegetables that are naturally grown and have not been subjected to pesticides and harmful chemical fertilizers. When growing green vegetables, fertilizers are carefully selected.

Scientific mixing of organic and inorganic fertilizers. The soil in the planting area should also have some resistance to insects.

Green vegetables refer to the general term of safe, high-quality and nutritious vegetables that follow the principle of sustainable development, under the premise of a good ecological environment in the production area, are produced in accordance with a specific quality standard system, and are recognized by specialized agencies and allow the use of green food labels. It is necessary to stay away from factories, mining enterprises and traffic arteries that emit harmful substances, and ensure that the environment for our vegetable planting is clean and free of dust, toxic gas and ecological pollution. Choose fertile soil, and do a good job of preparing the vegetable plot, before planting vegetables, you should first choose a good plot with fertile land, and it is best not to choose poor or clay soil, because it is not suitable for the cultivation of most vegetables.

In rural areas, the number of organic fertilizers is not only large, wide, and convenient, but also reduces the cost of agricultural production and the impact of chemicals on vegetables. Therefore, in the process of planting green vegetables, it is necessary to focus on farmhouse organic fertilizer. It is necessary to choose high-quality, high-yield, disease-resistant and pest-resistant varieties, and it can also be said that excellent vegetable varieties are the basis for planting green vegetables with high yield and high quality.
